iOS通过UIAlertView实现Android Toast效果

        本文介绍如何实现自动关闭的UIAlertView，类似Android的Toast效果。

        废话不多说，直接上代码：

- (void)alertCenter:(NSString *)message{    NSString *title = @"AlertTitle";    UIAlertView *alert = [[UIAlertView alloc]initWithTitle:title message:message delegate:nil cancelButtonTitle:nil otherButtonTitles:nil];    [alert show];    // dismiss after 3 seconds    dispatch_time_t time = dispatch_time(DISPATCH_TIME_NOW, 3ull * NSEC_PER_SEC);    dispatch_after(time, dispatch_get_main_queue(), ^{        [alert dismissWithClickedButtonIndex:0 animated:NO];    });}
