iPhone, how does one read an image from the UIPasteboard as NSData?

I have an image that I append a message to inside the NSData of the image and then save it to the photo library using ALAssetLibrary. I then send it to someone over email.

I want to give the user the option to press and hold a modified image and then press copy and paste it in my app. To do this my app would have to read the image that was copied either byte by byte to get the whole file (preferred method) or read the whole thing as an NSData.

How would I be able to read the general pasteboard's contents as NSData or byte for byte on a buffer?

Did you look at the documentation for UIPasteboard? The first thing that jumps out at me is:

- (NSData *)dataForPasteboardType:(NSString *)pasteboardType

You could use the below code to read the image data from UIPasteboard .

UIPasteboard * pasteBoard = [UIPasteboard pasteboardWithName:@"CopyFrom" create:YES];
NSData *data = [pasteBoard dataForPasteboardType:@"com.appshop.copyfrom.imagedata"];
imageView.image = [UIImage imageWithData:data];
