ios - iOS分享扩展未显示我的自定义ShareViewController

我似乎无法展示我的自定义ShareViewController。我继承了UIViewController，而不是SLComposeViewController，将其添加到Storyboard中，但是当我选择要共享的图像时，不会显示ShareViewController。这是我的整个代码:

头文件:

#import <UIKit/UIKit.h>
#import <Social/Social.h>

@interface ShareViewController : UIViewController

@end

实施文件:

@implementation ShareViewController

- (void)viewDidLoad{
    [super viewDidLoad];
    self.view.alpha = 0;

}

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    self.view.transform = CGAffineTransformMakeTranslation(0, self.view.frame.size.height);
    [UIView animateWithDuration:0.25 animations:^
     {
         self.view.transform = CGAffineTransformIdentity;
     }];
}

- (void)dismiss
{
    [UIView animateWithDuration:0.20 animations:^
     {
         self.view.transform = CGAffineTransformMakeTranslation(0, self.view.frame.size.height);
     }
                     completion:^(BOOL finished)
     {
         [self.extensionContext completeRequestReturningItems:nil completionHandler:nil];
     }];
}

-(void)viewDidAppear:(BOOL)animated {

    [super viewDidAppear:YES];

    for (NSItemProvider* itemProvider in ((NSExtensionItem*)self.extensionContext.inputItems[0]).attachments )
    {
        if([itemProvider hasItemConformingToTypeIdentifier:@"public.image"])
        {
            [itemProvider loadItemForTypeIdentifier:@"public.image" options:nil completionHandler:
             ^(id<NSSecureCoding> item, NSError *error)
             {
                 UIImage *sharedImage = nil;
                 if([(NSObject*)item isKindOfClass:[NSURL class]])
                 {
                     sharedImage = [UIImage imageWithData:[NSData dataWithContentsOfURL:(NSURL*)item]];


                 }
                 if([(NSObject*)item isKindOfClass:[UIImage class]])
                 {
                     sharedImage = (UIImage*)item;
                 }
             }];
        }
    }
}

@end

断点指示运行时确实执行代码，甚至捕获图像，但由于某些原因未显示自定义视图控制器。有什么帮助吗？

最佳答案

它是如此愚蠢，花了我一段时间才弄清楚，但是由于某种原因，默认情况下，自定义ShareViewController视图的背景色设置为[UIColor clearColor]。苹果很愚蠢:)，但我解决了这种情况
