关于UIAlertView弹出警告框自动消失

很多事时候弹出框只是为了提示用户，为了避免让用户过多不必要的操作，让弹出框自动消失就可以了

+ (void)showDismissedAlertDialog:(NSString*)message {

UIAlertView* alert = [[UIAlertView alloc] initWithTitle:nil   //NSLocalizedString(@"错误", nil)

message:NSLocalizedString(message, nil)

delegate:self

cancelButtonTitle:nil

otherButtonTitles:nil, nil];

[NSTimer scheduledTimerWithTimeInterval:1.5f

target:self

selector:@selector(timerFireMethod:)

userInfo:alert

repeats:YES];    //弹出框消失倒计时

[alert show];

}

#pragma mark -- 弹出框自动消失  使用倒计时

+ (void)timerFireMethod:(NSTimer*)theTimer//弹出框

{

UIAlertView *promptAlert = (UIAlertView*)[theTimer userInfo];

[promptAlert dismissWithClickedButtonIndex:0 animated:NO];

promptAlert = nil;

[theTimer invalidate];//使计时器无效

}
