自动转屏适配调节
//Appdelegate.m
#import "MainViewController.h"
MainViewController * main=[[MainViewController alloc]init];
self.window.rootViewController=main;
[self.window makeKeyAndVisible];
@interface
#define SCREENWIDTH [[UIScreen mainScreen] bounds].size.width
#define SCREENHEIGHT [[UIScreen mainScreen] bounds].size.height;
UIButton * btn;
UITextField * text;
//MainViewController.m
-(void)viewDidLoad
[super viewDidLoad];
NSLog(@"w=%g,h=%g",SCREENWIDTH,SCREENHEIGHT);
//自动调节
self.view.backgroundColor=[UIColor greenColor];
//距离左右距离固定
text=[[UITextField alloc]initWithFrame:CGRectMake(20,20,SCREENWIDTH-2*20,50)];
text.autoresizeingMask=UIViewAutoresizeingFLexibleRightMargin|UIViewAutoresizingFlexibleLefgMargin|UIViewAutoresizeingFlexibleWidth;//距离左右距离不变,宽度自动变化
[self.view addSubview:text];

btn.backgroundColor=[UIColor redColor];
btn.autoresizeingMask=UIViewAutoresizeingFLexibleRightMargin|UIViewAutoresizingFlexibleLefgMargin|UIViewAutoresizeingFlexibleWidth|UIViewAutoresizeingTopMargin;
[self.view addSubvie:btn];
第三种解决转屏的方案:交换视图
//APPdelegate.m
#import "MainViewController.h"
MainViewController * main=[[MainViewController alloc]init];
self.window.rootVieController=main;
[self.window makeKeyAndVisible];
#import "Portrait.h"
#import "Landscape.h"
@interface
Portrait * v;
Landscape * h;
float width,height;
//MainViewController.m
-(void)viewDidLoad
[super viewDidLoad];
self.backgroundColor=[UIColor greenColor];
v=[[Portrait alloc]init];
h=[[Landscape alloc]init];
width=[[UIScreen mainScreen]bounds].size.width;
height=[[UIScreeen mainScreen]bounds].size.height;
//得到屏幕转向
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(change) name:UIDeviceOrientationDidChangeNotification object:nil];
-(void)change
NSLog(@"转屏");
if([[UIDevice currentDevice]orientation]==UIDeviceOrientationPortrait)
self.view=v;
self.view.frame=CGRectMake(0,0,width,height);
else if([[UIDevice currentDevice]orientation]==UIDeviceOrientationLeft)
self.view=h;
self.view.frame=CGRectMake(0,0,height,width);
else if([[UIDevice currentDevice]orientation]==UIDeviceOrientationRight)
self.view=h;
self.view.frame=CGRectMake(0,0,height,width);
//还有一个上边,这个事件不应该进行处理
//Portrait.m 肖像竖着 继承UIView
-(instancetype)initWithFrame:(CGRect)frame
self=[super initWithFrame:frame];
if(self)
self.backgroundColor=[UIColor redColor];
return self;
//Lanscape.m 景观横着 继承UIView
-(instancetype)initWithFrame:(CGRect)frame
self=[super initWithFrame:frame];
if(self)
self.backgroundColor=[UIColor blueColor];
return self;
Auto Layout
大屏幕适配自动布局:新技术,采用约束
使用代码进行约束自动布局
//APPdelegate.m
[self.window makeKeyAndVisible];
@interface
//ViewController.m
-(void)viewDidLoad
[super viewDidLoad];
//UIView * left=[[UIView alloc]initWithFrame:CGRectMake(20,20,100,100)];
UIView * left=[[UIView alloc]init];
left.translatesAutoresizingMaskIntoConstraints=NO;//关闭系统自带约束
left.backgroundColor=[UIColor redColor];
[self.view addSubview:left];
// UIView * right=[[UIView alloc]initWithFrame:CGRectMake(self.view.frame.size-20-100,20,100,100)];
UIView * right=[[UIView alloc]init];
right.translatesAutoresizingMaskIntoConstraints=NO;
right.backgroundColor=[UIColor greenColor];
[self.view addSubview:right];
NSLayoutConstraint * constraint;
//约束 离左20 离上20 高度20 宽度20
//左约束 NSLayoutAttributeLeading
constraint=[NSLayoutConstraint constraintWithItem:left attribute:NSLayoutAttributeLeading relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeLeading multiplier:1.0 constant:20.0];
[self.view addSubview:constraint];
//上约束 NSLayoutAttributeTop
constraint=[NSLayoutConstraint constraintWithItem:left attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTop multiplier:1.0 constant:20.0];
[self.view addSubview:constraint];
//宽度约束
constraint=[NSLayoutConstraint constraintWithItem:left attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNoAnAttribute multiplier:1.0 constant:100.0];
[self.view addSubview:constraint];
//高度约束
constraint=[NSLayoutConstraint constraintWithItem:left attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNoAnAttribute multiplier:1.0 constant:100.0];
[self.view addSubview:constraint];
//右约束
constraint=[NSLayoutConstraint constraintWithItem:right attribute:NSLayoutAttributeTrailing relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTrailing multiplier:1.0 constant:-20.0];
[self.view addSubview:constraint];
//上约束 NSLayoutAttributeTop
constraint=[NSLayoutConstraint constraintWithItem:right attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTop multiplier:1.0 constant:20.0];
[self.view addSubview:constraint];
//宽度约束
constraint=[NSLayoutConstraint constraintWithItem:right attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNoAnAttribute multiplier:1.0 constant:100.0];
[self.view addSubview:constraint];
//高度约束
constraint=[NSLayoutConstraint constraintWithItem:right attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:nil attribute:NSLayoutAttributeNoAnAttribute multiplier:1.0 constant:100.0];
[self.view addSubview:constraint];
基于界面的约束自动布局
Main.storyboard View Controller
设置左右距离一定:
两控件左对齐:
两控件相对距离:command键连选,拖拽
43章
UISplitViewController
分割和弹出视图UISplitViewController:用于ipad上
//Appdelegate.m
#import "MenuTableViewController.h"
#import "DetailViewController.h"
MenuViewController * menu=[[MenuViewController alloc]init];
DetailViewCOntroller * detail=[[DetailViewController alloc]init];
menu.delegate=detail;//设置传值代理
UINavigationController * menuNav=[[UINavigationController alloc]initWithRootViewController:menu];
UINavigationController * detailNav=[[UINavigationController alloc]initWithRootViewCOntroller:detail];
NSArray * vcs=[[NSArray alloc]initWithObejects:menuNav,detailNav,nil];
UISplitViewController * svc=[[UISplitViewController alloc]init];
[svc setViewControllers:vcs];
self.window.rootViewController=svc;
[self.window makeKeyAndVisible];
#import "DetailViewController.h"//导入才能看到协议
@interface
@property (strong,onatomic) NSArray * strs;
@property (strong,onatomic) id<PassValue> delegate;//实现协议的对象
//MenuTableViewController.m
-(void)viewLoad
[super viewLoad];
self.strs=[NSArray arrayWithObjects:@"11",@"22",@"33",@"44",@"55",@"66",nil];
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
return 1;
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return self.strs.count;
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString * cellid=@"mycell";
UITableViewCell * cell=[tableView dequeueReusableCellWithIdentifier:cellid];//从可使用单元获取一个单元
if(cell==nil)
cell=[[UIatableViewCell alloc]initWithStyle:UITableViewCellStyleDefault resueIdentifier:cellid];
cell.textLabel.text=self.strs[indexPath.row];
return cell;
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexpath:(NSIndexPath *)indexPath
NSString * str=self.strs[indexPath.row];
[self.delegate setString:str];
//理论上应该单独创建一个协议文件
@protocol PassValue
-(void)setString:(NSString *)str;
@end
@interface DetailViewController:UIViewController<PassValue>
UILabel * label;
//DetailViewController.m
-(void)viewLoad
[super viewLoad];
self.view.backgroundColor=[UIColor orangeColor];
label=[[UILabel alloc]initWihtFrame:CGRectMake(300,100,200,40)];
label.backgroundColor=[UICoor greenColor];
label.text=@"显示选中";
[self.view addSubview:label];
-(void)setString:(NSString *)str
self.label.text=str;
竖向隐藏详细视图(拖拽才显示),横向显示。
前面介绍的都是基于代码的开发方式。(团队开发程序)
接来下介绍的是基于nib的界面设计开发方式。
最后还有一种苹果主推的一种开发方式:基于故事版。(快速开发程序)
44-45章
nib介绍
//AppDelegate.m
#import "MainViewController.m"
Main.window.background * main=[[MainViewCOntroller alloc]initWithNibName:@"MainViewController" bundle:nil];//视图有xib文件时候可以采用基于xib创建
self.window.rootViewController=main;
//MainViewController.h
-(IBAction)buttonTap:(UIButton *)sender;//操作就是一个事件
@property (weak,nonatomic)IBOutlet UILabel * label;//输出口
-(IBAction)calTap:(id)sender;
@property(weak,nonatomic)IBOutlet UITextField * numberText;
-(IBAction)closeKeyboard:(id)sender;
//MainViewController.m xib文件创建视图控制器对应的视图界面
-(void)loadView
//首先加载视图,然后再调用viewDidLoad,混合编程
-(void)viewDidLoad
[super viewDidLoad];
/*
UIButton * btn=[[UIButtton alloc]initWithFrame:CGRectMake(0,200,200,40)];
btn.backgroundColor=[UIColor greenColor];
[self.view addSubview:btn];
*/
-(IBAction)buttonTap:(UIButton *)sender
NSLog(@"this is tap!");
self.label.text=@"访问到我了!";
-(IBAction)calTap:(id)sender
NSString * str=self.numberText.text;
int num=[str intValue];//如果输入一个非数值型字符串,转换为0
int sum=0;
for(int i=1;i<=num;i++) sum+=i;
self.numberText.text=[NSSstring stringWithFromat:@"%d",sum];
-(IBAction)closeKeyboard:(id)sender
//[self.numberText resignFirstResponder];可以不写
属性检查器。对象库。父类。尺寸检查器。
2)基于nib的界面设计输出口和操作
拖拽方式实现target事件。
基本编辑样式,助手编辑样式,版本编辑样式。
助手编辑状态下拖拽(按住comand键),将代码窗口和界面窗口放在一起,选中头文件。
要想访问某个控件用output,要想响应某个事件用action。
删除。连接检查器。
空心代表已经不和界面上的东西关联在一起了。
重新关联。直接拖拽(按住[外链图片转存失败,源站可能有防盗链机制,建议将图片保存下来直接上传(img-Mm5vXYJP-1654594428640)(F:\\Learn of ios\\Image\\Image00\\image-20220528105816894.png)]command键)。
另一种添加方式:
3)基于nib的界面设计控件
ALpha:控件的透明度。
按钮:定制图片展示Custom。在父类进行背景颜色设置。
Capitalizetion:有无大小写
Correction:有无拼写检查
Keyboard Type:键盘选择 Return key:回车样式 go
结束退出输入关闭键盘:
另一种关闭方法点击视图空白处关闭键盘:选中视图,选择标识检查器。
4)基于nib的界面设计控件
分段控件:
Tint:选中时渲染的颜色。Selected:默认选中。
-(IBAction)setgChang:(UISegmentedControl *)sender;
//MainViewControler.m
-(IBAction)setgChang:(UISegmentedControl *)sender
NSLog(@"%d",sender.selectedSegmentIndex);
滑块控件:
开关控件:valueChange事件
活动指示器控件:Animating旋转
进度条控件:
文件所有者(MainViewController),第一响应者(指视图上谁正在获得焦点),视图。
表控件:
//Appliaction.m
//创建ViewController视图,勾选xib文件,首先拖拽
MainViewController * main=[[MainViewController alloc]initWithNibName:MainViewController bundle:nil];
self.window.rootViewController=main;
-(IBAction)setgChang:(UISegmentedControl *)sender;
@interface MainViewController:UIViewController<UITableViewDataSource,UITableViewDelegate>
//MainViewControler.m
-(IBAction)setgChang:(UISegmentedControl *)sender
NSLog(@"%d",sender.selectedSegmentIndex);
-(NSInteger)numberOfSectionInTableView:(UITableView *)tableView
return 1;
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return 10;
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
static NSString * cellid=@"mycell";
UITableViewCell * cell=[tableVieww dequeueReusableCellWithIdentifier:cellid];
if(cell==nil)
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault resuseIdentifier:cellid];
cell.textLabel.text=@"hello";
return cell;
要想使用界面定制表格还需要关联:
5)基于nib的界面设计控件-表格单元的定制
表控件:
//Appliaction.m
//创建ViewController视图,勾选xib文件,首先拖拽
MainViewController * main=[[MainViewController alloc]initWithNibName:MainViewController bundle:nil];
self.window.rootViewController=main;
#import "TableViewCell.h"
@interface MainViewController:UIViewController<UITableViewDataSource,UITableViewDelegate>
@property (weak,nonatomic)IBOutlet UITableView * tableView;
//MainViewControler.m
-(void)viewDidLoad
[super viewDidLoad];
//加载xib 到内存
UINib * nib=[[UINib alloc]initWithNibName:@"TableCell" bundle:nil];//bundle表示在那个树里面,当前树的话用nil
//注册xib到表视图
[ self.tableView registerNib:nib forCellReuseIdentifier:@"one"];
UINib * nib2=[[UINib alloc]initWithNibName:@"OtherTableCell" bundle:nil];
[ self.tableView registerNib:nib2 forCellReuseIdentifier:@"two"];
//实现UITableViewDataSource和UIableViewDelegate两个协议后至需要实现三个协议
-(NSInteger)numberOfSectionInTableView:(UITableView *)tableView
return 1;
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
return 10;
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
//static NSString * cellid=@"mycell";
//UITableViewCell * cell=[tableView dequeueReusableCellWithIdentifier:cellid];
/*已经加载进来了
if(cell==nil)
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault resuseIdentifier:cellid];
cell.textLabel.text=@"hello";
*/
// UILabel *label=(UILabel *)[cell viewWithTag:10];
//label.text=@"hello";//另外一种访问方式,新建一个类UITableViewCell
int row=indexPath.row;
TableViewCell * cell;
if(row%2==0)
cell=[tableView dequeueReusableCellWithIdentifier:@"one"];
cell.label.text=@"hello1";
else
cell=[tableView dequeueReusableCellWithIdentifier:@"two"];
return cell;
//调节高度
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
return 60;
@interface TableViewCell:UITableViewCell
@property(weak,nonatomic)IBOutlet UILabel * label;
-(IBAction)btnTap:(id)sender;
//TableViewCell.m
-(IBAction)btnTap:(id)sender
NSLog(@"xxxx");
关联界面表格单元和创建的类TableViewCell
创建输出口:
添加一个按钮:拖拽操作事件
创建空的xib文件。TableCell.xib
首先要设置下单元的标识id。one。
创建表格的输出口。
6)基于nib的界面设计控件
基于上一个工程:
新建OtherTableViewCell.xib文件:
贯穿线:
separator:分隔符
Bouncs:蹦蹦跳跳
基于nib的其他控件:
//AppDelegate.m
#import "MainViewController.h"
MainViewContorller * main=[[MainViewController alloc]initWithNibName:@"MainViewController" bundle:nil];
self.window.rootViewController=main;
//MainViewController.m .xib
图片控件:
多行文本框。
时间日期选择器。
手势识别。点击几次,几个手指。
需要实现:
布局管理
基于nib的布局和转屏处理
//AppDelegate.m
#import "MainViewController.h"
#import "DoubleViewController.h"
//MainViewController * main=[[MainViewController alloc]init];
DoubleViewController * main=[[DoubleViewController alloc]init];
self.window.rootViewController=main;
//MainViewController.m .xib
双视图切换:
@interface
@property(strong,nonatomic)IBOutLet UIView *v;
@property(strong,nonatomic)IBOutLet UIView *h;
//DoubleViewController.m .xib
-(void)viewDidLoad
[super viewDidLoad];
//监听转屏
[[NSNotificationCenter defacultCenter]addObsever:slef selector:@selector(change) name:UIDeviceOritationDidChangeNotification object:nil]
-(void)change
if([[UIDevice currentDevice]orienttation]==UIInterfaceOrientationPortrait)
self.view=self.v;
else if([[UIDevice currentDevice]orienttation]==UIInterfaceOrientationLeft)
self.view=self.h;
else if([[UIDevice currentDevice]orienttation]==UIInterfaceOrientationRight)
self.view=self.h;
按住option键拖拽创建另外一个视图。
创建输出口:
//自动适配方案。
选中视图,文件检查器中取消自动布局。选中控件,尺寸检查器。Autoresizing自动约束,选择距离。
46-50章
Storyborad
故事板:可以多视图开发,不适合大项目团队开发。
创建Single View Application 项目:有了Main.storyboard在创建应用程序时就不在需要创建主视图了。
新建空项目:
指定主接口。创建其类:
关联:
助手编辑状态:
界面切换:再拖拽一个,并创建关联的类OherViewControll.m。进入助手编辑状态,响应事件。
直接连线:
导航视图用进栈push,视图切换用模态modal。
