【问题描述】：

在我的应用程序中，我添加了一个滚动视图和一个表格视图作为子视图，在这个滚动视图上，我将多个菜单按钮（UI 按钮）作为子视图添加到了我的滚动视图中。我想要根据相应的菜单按钮加载具有不同数组的表视图。有什么想法吗？

- (void)viewDidLoad

    [super viewDidLoad];
    [self PutButtoninScrollView:7];


-(void)PutButtoninScrollView:(int)numberOfbuttons

    myButton1=[[UIButton alloc]init];
    myButton1= [UIButton buttonWithType:UIButtonTypeCustom];
    myButton1.frame=CGRectMake(5, 5, 70, 30);
    [myButton1 setTitle:@"दुनिया" forState:UIControlStateNormal];
    [myButton1 setTag:1];
    myButton1.backgroundColor=[UIColor blackColor];
    [myButton1 addTarget:self action:@selector(ListViewAction:) forControlEvents:UIControlEventTouchUpInside];
    [self.myScrollView addSubview:myButton1];

    myButton2=[[UIButton alloc]init];
    myButton2= [UIButton buttonWithType:UIButtonTypeRoundedRect];
    myButton2.frame=CGRectMake(80, 5, 70, 30);
    [myButton2 setTitle:@"India" forState:UIControlStateNormal];
    [myButton2 addTarget:self action:@selector(ListViewAction:) forControlEvents:UIControlEventTouchUpInside];
    [self.myScrollView addSubview:myButton2];
    [self.myScrollView setContentSize:CGSizeMake(160, 35)];
    _myScrollView.backgroundColor=[UIColor redColor];
    [self.view addSubview:self.myScrollView];


-(void)ListViewAction:(id)sender

    NSLog(@"sucessful");        

    if ([myButton.currentTitle isEqualToString:@"दुनिया"])
    
        NSLog(@"successful again 1");
    
    else if ([myButton.currentTitle isEqualToString:@"भारत"])
    
        NSLog(@"successful again 2");
            

问题是当我执行代码时 显示“成功”。这意味着 ListViewAction 方法被调用，但我的 if 语句从未执行。

【问题讨论】：

我们可以借助tag或者id指针来实现...

【参考方案1】：

试试这个

    -(void)PutButtoninScrollView:(int)numberOfbuttons

xPosition=5;
for(int i=0;i<numberOfbuttons;i++)


    myButton= [UIButton buttonWithType:UIButtonTypeRoundedRect];
    myButton.frame=CGRectMake(xPosition, 5, 70, 30);
    myButton.backgroundColor=[UIColor redColor];
   [myButton setTitle:[NSString stringWithFormat:@"%d",i] forState:UIControlStateNormal];
    [myButton setTag:i];
    [myButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
    [self.myScrollView addSubview:myButton];
    xPosition+=75;

[self.myScrollView setContentSize:CGSizeMake(xPosition,35)];
_myScrollView.backgroundColor=[UIColor redColor];
[self.view addSubview:self.myScrollView];


  - (void) buttonClicked:(id) sender

   NSString *strTitle = [sender currentTitle];
 // arrItem have list of array items
   NextView  *detailViewController = [[NextView alloc] initWithNibName:@"NextView" bundle:nil];
   detailViewController.arrTableView =[arrItem objectAtIndex:[strTitle integerValue]];
  [self.navigationController pushViewController:detailViewController animated:YES];

【讨论】：

可能是 uibutton 添加为子视图的问题。我已经阅读了有关 UIGestureRecognizer 的信息。但是不知道怎么用

【参考方案2】：

-(void)ListViewAction:(id)sender NSLog(@"成功");

if ([[sender currentTitle] isEqualToString:@"दुनिया"])

    NSLog(@"successful again 1");

else if ([[sender currentTitle] isEqualToString:@"भारत"])

    NSLog(@"successful again 2");

最终它以这种方式工作。只需将发件人而不是我的按钮放在 ListViewActionthanx 为您的帮助@Ravindhiran

【参考方案3】：

试试这个

[myButton1 addTarget:self action:@selector(ListViewAction:) forControlEvents:UIControlEventTouchUpInside];
[myButton2 addTarget:self action:@selector(ListViewAction:) forControlEvents:UIControlEventTouchUpInside];

【讨论】：

对不起，我的代码中是 (ListViewAction:)。我的 ListViewAction 工作正常。我得到输出字符串“成功”。我想要的是执行“再次成功1”和“再次成功2”

终于找到了解决办法：-(void)ListViewAction:(id)sender if ([[sender currentTitle] isEqualToString:@"दुनिया"]) NSLog(@"successful again"); else if ([[sender currentTitle] isEqualToString:@"भारत"]) NSLog(@"successful again1");
