How do you save a picture with NSUserDefaults?

问题

I have a iPad app that can take a picture and then put it within a image view. How do I go about saving the pic that I have stored in the image view? Here is what I have tried so far: [imageView setImage:[[NSUserDefaults standardUserDefaults] objectForKey:@"storedImageValue6"]];

回答1:

Pretty much you have to convert it to NSData and vice versa. Take a look at this link: Save images in NSUserDefaults?

回答2:

Here imageSet is UIImage

 NSData *imagedata=UIImagePNGRepresentation(imageSet);
[[NSUserDefaults standardUserDefaults] setObject:imagedata forKey:@"Theme Selecting"];    
[[NSUserDefaults standardUserDefaults] synchronize];

You can use this code for saving image
