NSData File Size

[Bertrand21]

Hey Guys,
I am trying to figure out the size of a file. I am writing the NSData to my Documents directory. This is working great but i would like to know how many megabytes the file i wrote is.

I want to get a value like 2.5 megabytes or something like that.

Thanks for your help!

Just call the length method on the data and it will tell you how many bytes it has.

I use myData.bytes

This gives me the bytes but how do I translate that to megabytes?
Thanks!

No, not bytes, length. Like this:
[myData length]

And then you divide that by 2^20

I guess the bytes is a little misleading! Thanks a lot kelvinkao! THis works perfectly!!!!
