Ios 从另一个视图类隐藏带有标记的按钮不起作用。

我是iOS的新手。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外设置了一个停止按钮。我想设置何时按下停止按钮，然后我想隐藏我选择的按钮，但它不起作用，但当我在视图中单击同一按钮时，它是隐藏的，但我想在这里隐藏选择按钮当停止按钮被点击在这里，我写的代码如下

-(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;
  }
 }

这个方法在我的视图1中，现在我在按下停止按钮时调用这个方法，如下所示

- (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];
    }
  }

-（iAction）停止所有玩家：（id）发送者
{
view1=[[view1 alloc]init]；
SaveSoundIntoArray*saveInfointoArray=[SaveSoundIntoArray sharedInstance]；
if（saveInfointoArray.stopAllPlayer.count==0）
{
UIAlertView*alert=[[UIAlertView alloc]initWithTitle:@“选择为空”消息：@“您的选择为空”委托：自取消按钮：@“确定”其他按钮：无，无]；
[警报显示]；
}
其他的
{
对于（int i=0；i您可以使用：

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

我在哪里使用它？你能帮我吗？我假设你的“copyOfStopAllPlayer”-数组包含正确的对象，因为我不知道“SaveSoundIntoArray”类中发生的事情（如果不知道，你应该在使用之前初始化“copyOfStopAllPlayer”数组）-在迭代“copyOfStopAllPlayer”数组，int currentTag=clickedButton.tag。。。
