I am creating a plist from my OSX app that contains some images. I am writing the image by :
[NSKeyedArchiver archivedDataWithRootObject:self.someImage]
Then I am using this plist file as a template for iOS app, but here I can't convert the file to UIImage
and neither to NSImage
(as this is only for OSX).
I am getting this error:
* Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: '* -[NSKeyedUnarchiver decodeObjectForKey:]: cannot decode object of class (NSImage)'
Please suggest me a way to perform the above.
OS X:
Instead of using NSKeyedArchiver
to convert an NSImage
to NSData
, use NSImage
's TIFFRepresentation
method:
NSData *imageData = [self.someImage TIFFRepresentation];
// save imageData to file
iOS:
Read the image data from the file, then convert it to a UIImage using UIImage's +imageWithData:
convenience constructor:
NSData *imageData = ...; // load imageData from file
UIImage *image = [UIImage imageWithData: imageData];
