iOS开发之截屏

今天分享一个比较少用到的功能---截屏,时间比较紧功能也比较简单,就不多讲解了,直接分享代码

 @implementation UIView (ImageSnapshot) 
 - (UIImage*)imageSnapshot { 
     UIGraphicsBeginImageContextWithOptions(self.bounds.size,YES,self.contentScaleFactor); 
     [self drawViewHierarchyInRect:self.bounds afterScreenUpdates:YES]; 
     UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext(); 
     UIGraphicsEndImageContext(); 
     return newImage; 
 } 
 @end

如果用到的小伙伴可以直接C-V过去
