推荐答案

尝试这样做，如果它有帮助：

Try this if it helps :

CGSize itemSize = CGSizeMake(kAppIconWidth, kAppIconHeight);
UIGraphicsBeginImageContext(itemSize);
CGRect imageRect = CGRectMake(0.0, 0.0, itemSize.width, itemSize.height);
[image drawInRect:imageRect];
self.cell.image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
