I am trying to NSLog
the number of megs my NSData
object is however currently all I can get is bytes by using
NSLog(@"%u", myData.length);
So how would I change this NSLog
statement so I can see something like
2.00 megs
any help would be appreciated.
There are 1000 bytes in a kilobyte and 1000 kilobytes in a megabyte, so...
NSLog(@"File size is : %.2f MB",(float)myData.length/1000.0f/1000.0f);
Mind you, this is a simplistic approach that doesn’t handle particularly large or small numbers. A more generalized solution is to use Apple’s NSByteCountFormatter:
Or for OS X 10.8+ and iOS 6+
NSLog(@"%@", [[NSByteCountFormatter new] stringFromByteCount:data.length]);
In Swift:
print(ByteCountFormatter().string(fromByteCount: Int64(data.count)))
