UITableView中改变UIImage尺寸的方法
UIImage *image = [UIImage imageNamed:@"YourImage.png"]; UIImage *tempImage = nil; CGSize targetSize = CGSizeMake(48,48); //你想要的图片尺寸 UIGraphicsBeginImageContext(targetSize); CGRect thumbnailRect = CGRectMake(0, 0, 0, 0); thumbnailRect.origin = CGPointMake(0.0,0.0); thumbnailRect.size.width = targetSize.width; thumbnailRect.size.height = targetSize.height; [image drawInRect:thumbnailRect]; tempImage = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); cell.img.image = tempImage; //这里我是自定义了cell，将Image重置为新的tempImage即可
