数据验证功能实现,修改联系人,拼音显示分组,搜索

添加数据到表视图:

添加完数据之后,数据需要传递回主视图进行显示,数据传送有两种方式:代理和属性。属性是一个固定数据,根视图无法处理。而代理可以通过调用行为的方式对数据进行处理。

    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

    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];

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-iYXvYwNa-1654005542544)(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。
