captureScreen截图Bug

[tsyouasd]

• (UIImage *)__captureScreen {

  //self.view.bounds.size, self.view.opaque
  UIGraphicsBeginImageContextWithOptions(SCREEN_SIZE,self.view.opaque, 0);
  CGContextRef context = UIGraphicsGetCurrentContext();
  // [self.view.layer renderInContext:context]; 当前未修改的
  [[[UIApplication sharedApplication] keyWindow].layer renderInContext:context];//用keywindow可以解决tabbar截图黑屏的问题
  UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
  UIGraphicsEndImageContext();

  return image;
  }
