ios – 如何获取UIImage的大小(KB)

我从didFinishPickingMediaWithInfo获取图像.

UIImage *originalImage = (UIImage*)[info valueForKey:UIImagePickerControllerOriginalImage];

我想要获取Kb的图像的大小.

解决方法

UIImage *originalImage = (UIImage*)[info valueForKey:UIImagePickerControllerOriginalImage];
    NSData *imgData = UIImageJPEGRepresentation(originalImage,1); //1 it represents the quality of the image.
    NSLog(@"Size of Image(bytes):%d",[imgData length]);
    originalImage = nil;
