문제를 해결할 수있었습니다. "DEFacebookComposeViewController.h"

그냥 다음 코드 교체 :

• (무효) viewWillAppear : { [슈퍼 viewWillAppear 애니메이션 (BOOL)를 : 당신은 다음과 같은 파일의 코드 주석을 해제 할 필요가 애니메이션 ];

  // Take a snapshot of the current view, and make that our background after our view animates into place. 
  // This only works if our orientation is the same as the presenting view. 
  // If they don't match, just display the gray background. 
      if (self.interfaceOrientation == self.fromViewController.interfaceOrientation) { 
  //  UIImage *backgroundImage = [self captureScreen]; 
  //  self.backgroundImageView = [[[UIImageView alloc]    initWithImage:backgroundImage] autorelease]; 
      } 
      else { 
      //   self.backgroundImageView = [[[UIImageView alloc] initWithFrame:self.fromViewController.view.bounds] autorelease]; 
  } 
       // self.backgroundImageView.autoresizingMask = UIViewAutoresizingNone; 
  // self.backgroundImageView.alpha = 0.0f; 
  // self.backgroundImageView.backgroundColor = [UIColor lightGrayColor]; 
  // [self.view insertSubview:self.backgroundImageView atIndex:0]; 
  
  // Now let's fade in a gradient view over the presenting view. 
      self.gradientView = [[[DEFacebookGradientView alloc] initWithFrame:[UIApplication sharedApplication].keyWindow.bounds] autorelease]; 
      self.gradientView.autoresizingMask = UIViewAutoresizingNone; 
      self.gradientView.transform = self.fromViewController.view.transform; 
      self.gradientView.alpha = 0.0f; 
      self.gradientView.center = [UIApplication sharedApplication].keyWindow.center; 
      [self.fromViewController.view addSubview:self.gradientView]; 
      [UIView animateWithDuration:0.3f 
        animations:^ { 
         self.gradientView.alpha = 1.0f; 
        }];  
  
      self.previousStatusBarStyle = [UIApplication sharedApplication].statusBarStyle; 
      [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque animated:YES]; 
  
      [self updateFramesForOrientation:self.interfaceOrientation]; 
  
       }

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleBlackOpaque animated:YES]; 

[self updateFramesForOrientation:self.interfaceOrientation]; 

    } 

희망.

감사합니다.

Answer 2

그냥

appDelegate.window.rootViewController.modalPresentationStyle = UIModalPresentationCurrentContext; 

로 구현 모듈

self.modalPresentationStyle = UIModalPresentationCurrentContext; 

이 코드를 교체하고 작업이 완료 B 것, 어디서나 코드를 변경할 필요가 없습니다.
