ios - iPhone iOS8 : UIAlertView upside down rotation doesn't work fine when build from iOS7. 1 sdk 并在8.0及以上设备上运行

Question

任何人都知道如何为 iOS 8 设备修复此问题。是 Apple 的 UIAlertview 实现问题吗？

我有相同的屏幕截图。但由于信誉限制无法上传:(

Answer 1

在 IOS8 中添加了 UIAlertController 而不是 UIAlertView

if (([[[UIDevice currentDevice] systemVersion] compare:@"8.0" options:NSNumericSearch] == NSOrderedAscending)) {
    // use UIAlertView
}
else {
    // use UIAlertController

[self  showAlert];
}



-(void)showAlert

{
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"AlertView" message:nil preferredStyle:UIAlertControllerStyleActionSheet;
    UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"GO" style:UIAlertActionStyleDefault
    handler:^(UIAlertAction * action) {
    // [action doSomething];

    }];

    UIAlertAction* cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault
    handler:^(UIAlertAction * action) {
    [alert dismissViewControllerAnimated:YES completion:nil];

    }];

    [alert addAction:defaultAction];
    [alert addAction:cancel];
    [self presentViewController:alert animated:YES completion:nil];

    } 

尝试使用该解决方案。
