允许横向也可以查看uiimagepickercontroller推送的控制器

Question

我正面临一个关于横向定位的问题，以查看由uiimagepickercontroller推送的控制器。我在从选择器推送控制器的同时编写了以下代码。

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
        UIImage *editImage=[info objectForKey:UIImagePickerControllerEditedImage];
        NSData *data=[[ConstantIM shareInstance] compressImage:editImage];

        self.imgCirclephoto.image = [ConstantIM  imageWithImage:[UIImage imageWithData:data] scaledToWidth:[UIScreen mainScreen].bounds.size.width scaledToHeight:[UIScreen mainScreen].bounds.size.height];

        [[ConstantIM shareInstance] restrictRotation:NO];

        ImageChooseCancelView *cropController = [[ImageChooseCancelView alloc] initWithNibName:@"ImageChooseCancelView" bundle:nil];
        cropController.imgSel = editImage;
        cropController.imgDelegate = self;

        [picker pushViewController:cropController animated:YES];
}

在ImageChooseCancelView中，我编写了以下代码以允许横向模式：

- (NSUInteger)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskLandscape;
}

任何帮助将不胜感激。提前谢谢。

你必须改变interfaceOrienation mask。尝试在appDelegate中添加它

-(UIInterfaceOrientationMask)application:(UIApplication *)application
supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
    return UIInterfaceOrientationMaskAll;
else  //iPad 
    return UIInterfaceOrientationMaskAllButUpsideDown;
}
