【问题描述】：

我是 ios 新手。我制作了一个包含 Scrollview 的应用程序，在 Scrollview 中我添加了 10 页，每页包含 12 个按钮，并在我的 Scrollview 之外设置一个停止按钮，我想在按下停止按钮时设置，然后我想隐藏我选择的按钮，但它不起作用但是当我点击视图中的同一个按钮时，它是隐藏的，但是在这里我想在点击停止按钮时隐藏选定的按钮，我写代码就像

-(void)clikedOnButton:(UIButton*)whichButtonClicked

  SaveSoundIntoArray *saveInfointoArray=[SaveSoundIntoArray sharedInstance];
  if(whichButtonClicked.selected)
   
    NSLog(@"button selected is:%@",whichButtonClicked);
    NSUInteger butTag=(long)whichButtonClicked.tag;
    NSLog(@"button clicked is:%ld",butTag);
    switch (butTag)
    
        case 1:
        
            [[self.view viewWithTag:2] setHidden:YES];
            [[self.view viewWithTag:121] setHidden:YES];
            [saveInfointoArray.stopAllPlayer removeObject:saveInfointoArray.player1];  //when unselect the button ,remove object from array
            [saveInfointoArray.saveButtonName removeObject:whichButtonClicked]; //when unselect object button remove object from array
            [saveInfointoArray.selectedButtonButNotMoreThanTen removeObject:whichButtonClicked];
            [saveInfointoArray.VolumeSaveForPlayer removeObjectForKey:@"1"];
            totalSelectedButtonButNotMoreThanTen=[SaveSoundIntoArray countTotalSelectedButton:-1 and:1 and:0];
            whichButtonClicked.selected =NO;
            [saveInfointoArray.player1 stop];  //tap=2 , player1 stop
        
            break;
  
 

这个方法在我的 view1 中现在我在按下停止按钮时调用这个方法

- (IBAction)stopAllPlayers:(id)sender

view1=[[View1 alloc]init];
SaveSoundIntoArray *saveInfointoArray=[SaveSoundIntoArray sharedInstance];
if(saveInfointoArray.stopAllPlayer.count == 0)
 
 UIAlertView *alert=[[UIAlertView alloc]initWithTitle:@"Selection Empty" message:@"Your Selection is Empty" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
 [alert show];
 
else

for(int i=0;i<saveInfointoArray.stopAllPlayer.count;i++)

    copyOfSaveButtonName[i]=saveInfointoArray.saveButtonName[i];    //copy bcz loop mathi method call kriye tyare remove object thay 6
    copyOfStopAllPlayer[i]=saveInfointoArray.stopAllPlayer[i];  //copy bcz stopallplayer removeObject
    copyOfSaveButtonTag[i]=saveInfointoArray.saveButtonTag[i];  //copy bcz savebuttonTag removeObject

for(int i=0;i<copyOfStopAllPlayer.count;i++) //error here

    NSLog(@"button:%@ and Player:%@ is STOP",copyOfSaveButtonName[i],copyOfStopAllPlayer[i]);
    NSLog(@"button Tag is:%@",copyOfSaveButtonName[i]);
    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    button=copyOfSaveButtonName[i];
    button.selected=YES;
    NSLog(@"tag is :%@",copyOfSaveButtonTag[i]);
    int currentTag=[copyOfSaveButtonTag[i] intValue]; //use buttonTag for comparison of buttontags
    NSLog(@"currentTag: %d",currentTag);
    if(currentTag>=1 && currentTag<=12)
    
    [view1 clikedOnButton:button];
    
  

这里我没有从停止按钮获得按钮标签，我不知道，因为我对此感到困惑，请帮助我

谢谢。

【参考方案1】：

你可以使用：

UIButton *clickedButton = (UIButton*)sender;
NSLog(@"tag is : %i", clickedButton.tag)

【讨论】：

我在哪里使用它你能帮我吗？

我假设您的“copyOfStopAllPlayer” - 数组包含正确的对象，因为我不知道您的“SaveSoundIntoArray”类中发生的事情（如果不是，您应该在使用之前初始化“copyOfStopAllPlayer”数组) - 你可以使用“UIButton clickedButton = (UIButton)sender;”在迭代“copyOfStopAllPlayer”数组时，int currentTag = clickedButton.tag ...
