IOS8.3中的UIAlertviewController崩溃

Question

我使用的是UIAlertView，但在IOS8.3中，我更改为UIAlertViewController，因为UIAlertview不工作，但UIAlertViewController与错误崩溃

'UIApplicationInvalidInterfaceOrientation',
reason: 'Supported orientations has no common orientation with 
         the application, and 
         [ChartsTableViewController2_iPhone shouldAutorotate] is returning YES'

不知道该怎么办请帮帮我。

Answer 1

尝试将UIAlertController子类并添加此代码。希望能帮上忙。

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}

- (BOOL) shouldAutorotate {
    return YES;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
    return UIInterfaceOrientationPortrait;
}
