Supported orientations has no common orientation with the application, and [UIAlertController shouldAutorotate] is returning YES

某一個頁面橫屏時會出現崩潰的問題描述，原因是當你在AppDelegate中返回的設備方向是UIInterfaceOrientationMaskLandscapeLeft.但是你在視圖控制器中返回支持自動旋轉。就會拋出此異常。

解決方法 重寫UIAlertContrller 的shouldAutorotate 方法，

#import <UIKit/UIKit.h>
 
@interface UIAlertController (Rotation)
- (BOOL)shouldAutorotate;
@end


#import "UIAlertController+Rotation.h"
 
@implementation UIAlertController (Rotation)
- (BOOL)shouldAutorotate
{
    return NO;
}
@end

即可
