UIImageView 上面放一個button（或者其他的控件，需要添加手勢或者點擊事件）時，如果點擊的事件不觸發時

 我們需要把UIImageView與用戶的交互打開 

例如：

    UIImageView * Image = [[UIImageViewalloc]initWithFrame:CGRectMake(0,0,ScreenWidth, 215 *FitHeight)];

    Image.image = [UIImageimageNamed:@"userbackground@2x"];

    //imageView打開用戶交互

    Image.userInteractionEnabled = YES;

    [self.viewaddSubview:Image];

 //跳過按鈕

    UIButton *  SkipButton = [[UIButtonalloc]initWithFrame:CGRectMake(ScreenWidth - 70 * FitWidth,25 * FitHeight,50 * FitWidth,50 * FitHeight)];

    [SkipButton setTitle:@"跳過"forState:UIControlStateNormal];

    [SkipButton setTintColor:littleLabelColor];

    SkipButton.titleLabel.font =littleLabelFont;

    [SkipButton addTarget:selfaction:@selector(SkipButtonAction)forControlEvents:UIControlEventTouchUpInside];

    [BackgroundPicture addSubview:SkipButton];

#PRagma mark 跳過的點擊事件

-(void)SkipButtonAction{

    [self.navigationControllerpopViewControllerAnimated:YES];

}
