我的子視圖沒有響應點擊事件

Question

我正在創建一個顯示子視圖像ActionSheetView的應用程序，並且我已經通過插口添加了UIGridView和UIPageControll，但現在，當我單擊它沒有響應的單元格時，我的子視圖是一個ViewController筆尖文件。

如果我創建一個按鈕並以編程方式添加到我的popupview中，那麼它將顯示，並且還會獲得點擊事件，但任何插座都不會響應。

我試圖在我的子視圖中設置userinteraction使能，但它沒有任何好處。

這裏是我的第一個觀點的代碼，通過點擊barbutton顯示子視圖：

- (void)popUpView:(id)sender { 
    //self.view.backgroundColor = [UIColor darkGrayColor]; 

    bGView = [[UIView alloc] init]; /this is the background view and all view is added in it 
    bGView.frame = CGRectMake(0,0,320,490); 
    bGView.backgroundColor = [UIColor clearColor]; 
    bGView.alpha = 0.8 ; 

    CGRect viewFrame = CGRectMake(10, 90, 300, 300); 
    aPopUpViewController = [[PopUpViewController alloc] initWithNibName:@"PopUpViewController" bundle:nil];  //this is my view controller and when this shows on screen it display my greed view 

    aPopUpViewController.view.frame = viewFrame; 
    aPopUpViewController.view.userInteractionEnabled = YES; 

    [bGView addSubview:aPopUpViewController.view]; 

    button = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [button addTarget:self 
       action:@selector(aMethod:) 
    forControlEvents:UIControlEventTouchDown]; 
    button.backgroundColor = [UIColor clearColor]; 
    [button setBackgroundImage:[UIImage imageNamed:@"close_button.png"] forState:UIControlStateNormal]; 
    button.frame = CGRectMake(-1, 80, 30, 30); 
    [bGView addSubview:button]; 

    //for view animation 

    /* 
    // from bottom to center animation 

    [bGView setFrame:CGRectMake(0.0f, 480.0f, 320.0f, 480.0f)]; //notice this is OFF screen! 
    [UIView beginAnimations:@"animateTableView" context:nil]; 
    [UIView setAnimationDuration:0.4]; 
    [bGView setFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)]; //notice this is ON screen! 
    [UIView commitAnimations];*/ 

    //for page like effect 

    /*[UIView transitionWithView:self.view duration:0.5 
         options:UIViewAnimationOptionTransitionCurlUp //change to whatever animation you like 
        animations:^ { [self.view addSubview:bGView]; } 
        completion:nil];*/ 

    /*CATransition *transition = [CATransition animation]; 
    transition.duration = 1.0; 
    transition.type = kCATransitionReveal; //choose your animation 
    [bGView.layer addAnimation:transition forKey:nil]; 
    [self.view addSubview:bGView];*/ 

    aPopUpViewController.view.userInteractionEnabled = YES; 
    bGView.userInteractionEnabled = YES; 
    self.view.userInteractionEnabled = YES; 

    bGView.transform = CGAffineTransformMakeScale(0.01, 0.01); 
    [UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveEaseOut animations:^{ 
     bGView.transform = CGAffineTransformIdentity; 
    } completion:^(BOOL finished){ 
     // do something once the animation finishes, put it here 
    }]; 

    [self.view addSubview:bGView]; 


    addLabel.enabled = NO; 
    clipArt.enabled = NO; 
    emailItem.enabled = NO; 
    closeButton.enabled = NO; 
    self.navigationController.topViewController.title = @"Choose ClipArt"; 

    ExampleAppDataObject* theDataObject = [self theAppDataObject]; 

    theDataObject.navBarHide = @"no"; 

} 

- (void)aMethod:(id)sender 
{ 
    //[aPopUpViewController.view removeFromSuperview]; 
    //[button removeFromSuperview]; 

    /*[UIView transitionWithView:self.view duration:0.5 
         options:UIViewAnimationOptionTransitionCrossDissolve//change to whatever animation you like 
        animations:^ { [bGView removeFromSuperview]; } 
        completion:nil];*/ 

    [bGView removeFromSuperview]; 

    addLabel.enabled = YES; 
    clipArt.enabled = YES; 
    emailItem.enabled = YES; 
    closeButton.enabled = YES; 

    self.navigationController.topViewController.title = @"Greeting's"; 

    ExampleAppDataObject* theDataObject = [self theAppDataObject]; 

    theDataObject.navBarHide = @"yes"; 
} 

這是怎麼在我的屏幕看起來像

UPDATE

現在我想通了我的問題是，問題是我給我的整個視圖一個龍頭列表，現在我添加網格視圖作爲子視圖，所以當我點擊單元格，而不是選擇單元格它w生病生成視圖雙擊手勢，爲什麼從來沒有選定單元格，多數民衆贊成，這就是我想..

Answer 1

你在主視圖中添加子視圖每次添加後這一行..

[self.view bringSubviewToFront:yourGridView];
