detecting image size programmatically -iPhone

My application lets user take a picture with default camera on iPhone and send it to a server. Before sending it I would like to check the image size and let's say if the size is larger than 500 KB I would let the user know filesize is too big and would not send it. Is there a way to check the image size programmatically? Help would be appreciated.

If you convert it to NSData, you can check the length property. The file size in MB is bytes divide by 2^20.

To convert to NSData use UIImagePNGRepresentation()

UIImage *myImage = ...
NSData *imageData = UIImagePNGRepresentation(myImage);
