Ios8 iOS 8 UIAlertView未显示按钮
使用iOS 7.1中的UIAlertView在我的应用程序中显示一些警报在iOS 8中工作得非常完美警报会出现,但没有取消、确定和其他按钮。。。这会导致用户无法关闭警报,从而卡在该屏幕上,不得不关闭应用程序 我尝试为iOS UIAlertController 8实现UIAlertView和以前的版本,请参见下面的代码:Ios8 iOS 8 UIAlertView未显示按钮,ios8,uialertview,uialertcontroller,Ios8,Uialertview,Uialertcontroller,使用iOS 7.1中的UIAlertView在我的应用程序中显示一些警报在iOS 8中工作得非常完美警报会出现,但没有取消、确定和其他按钮。。。这会导致用户无法关闭警报,从而卡在该屏幕上,不得不关闭应用程序 我尝试为iOS UIAlertController 8实现UIAlertView和以前的版本,请参见下面的代码: if ([[[UIDevice currentDevice] systemVersion] floatValue] < 8.0) { UIAlert

}
对于这段代码,我也有同样的问题,这些按钮没有显示在警报中,有什么建议可以解决这个问题吗
请注意,我正在使用字符串进行国际化,它们通常可以工作,已经通过直接放置字符串(@“…)进行了测试,但不起作用。尝试以下方法:
UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"ALERTA!" message:@"What will you do?" **preferredStyle:UIAlertControllerStyleAlert**];
__weak ViewController *wself = self;
UIAlertAction *nao = [UIAlertAction actionWithTitle:@"I'm doing something" ***style:UIAlertActionStyleCancel*** handler:^(UIAlertAction *action) {
__strong ViewController *sself = wself;
sself.**lbl**.text = @"You did something!"; **//the text "You did something!" gets displayed on a label(if created) named lbl**
}];
[alert addAction:nao];
[self presentViewController:alert animated:NO completion:nil];
