How to get the Size (KB) of UIImage
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]); imgData = nil;
I think the op's size (kb) is the memory size of originalImage, right?
Check out the usage about malloc_size under the ARC refer to this.
#import <malloc/malloc.h>NSLog(@"Size of %@: %zd", NSStringFromClass([originalImage class]), malloc_size((__bridge const void *)originalImage));
