强制UIAlertView进入横向模式 [英] Forcing UIAlertView into landscape mode

问题描述

我需要在横向模式下显示UIAlertView。我尝试了显而易见的，在 willPresentAlertView：委托方法中设置转换无效：

I need to display a UIAlertView in landscape mode. I tried the obvious, setting the transform in the willPresentAlertView: delegate method to no avail:

-(void) willPresentAlertView:(UIAlertView *)alertView {

    alertView.transform = CGAffineTransformMakeRotation(M_PI_2);
}

有关如何解决此问题的任何建议吗？

Any suggestions on how to fix this?

推荐答案

您是否在 didPresentAlertView ？中尝试过

- (void)didPresentAlertView:(UIAlertView *)alertView
{
    // UIAlertView in landscape mode
    [UIView beginAnimations:@"" context:nil];
    [UIView setAnimationDuration:0.1];
    alertView.transform = CGAffineTransformRotate(alertView.transform, 3.14159/2);
    [UIView commitAnimations];
}
