活动指示器为5秒？

Question

所有

我试图UIActivityIndicator在viewdidappear方法上运行5秒钟.但我如何给活动指示器设定时间限制(5秒)？

这是代码 UIActivityIndicator

 UIActivityIndicatorView *activityView=[[UIActivityIndicatorView alloc]     initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

    activityView.center=self.view.center;

    [activityView startAnimating];

    [self.view addSubview:activityView];

Answer 1

有一行,没有其他依赖项和条件:

[activityView performSelector:@selector(removeFromSuperview) withObject:nil afterDelay:5.0];
