我想减少从 UIImagePickerController 获取的图像文件大小。我使用这种方法

I want to reduce image file size that take from UIImagePickerController . I use this method

NSData * imageData = UIImageJPEGRepresentation（image，0.1）;

NSData *imageData = UIImageJPEGRepresentation(image, 0.1);

但它将2.2 MB图像文件大小减少到300 KB
我希望我的图像文件大小小于100 KB。

推荐答案

以千克为单位缩小图像大小的最简单方法是减小像素大小！将其缩小：

Easiest way to reduce image size in kilos is to reduce the size in pixels! Scale it smaller:

CGFloat scaleSize = 0.2f;
UIImage *smallImage = [UIImage imageWithCGImage:image.CGImage
                      scale:scaleSize
                      orientation:image.imageOrientation];
