Question
I tying to check my image size after picking form the photo library by using this code.
NSData *imageData1 = [[NSData alloc] initWithData:UIImageJPEGRepresentation((imageview.image), 0.5)];
int imageSize = imageData1.length;
NSLog(@"SIZE OF IMAGE: %i ", imageSize);
But showing something like this .
SIZE OF IMAGE: 237125
But i want to view the image size in the MB format like 25 MB how to do pls tell me how to do it.
thanks.
Solution
imageSize
has data length in bytes. You need to convert it to Mb
NSLog(@"SIZE OF IMAGE: %i Mb", imageSize/1024/1024);
UPDATE:
You can also use following code
NSLog(@"SIZE OF IMAGE: %.2f Mb", (float)imageSize/1024/1024);
to receive output like
SIZE OF IMAGE: 0.23 Mb
for sizes less the 1 Mb.
OTHER TIPS
[NSByteCountFormatter stringFromByteCount:imageSize
countStyle:NSByteCountFormatterCountStyleFile];
Complementing @rounak 's answer, in Swift 3:
ByteCountFormatter.string(fromByteCount: Int64(imageSize), countStyle: .file)
