convert NSData Length from bytes to megs

Question

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.

Accepted Answer

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)))
```
