Methods of saving images to NSUserDefaults:

Number 1: Saving and retrieving image directly:

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSData *imageData = [NSKeyedArchiver archivedDataWithRootObject:imageView.image];
[userDefaults setObject:imageData forKey:@"Image"];

//Retrieving
UIImage *image = (UIImage*)[NSKeyedUnarchiver unarchiveObjectWithData:[userDefaults objectForKey:@"Image"]];

Number 2: Saving the image in documents directory and saving its path in NSUserDefaults:

//Saving
//Obtain the path for Documents Directory
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];      

//Append Image name to the path
NSString *imagePath = [[documentsDirectory stringByAppendingPathComponent:@"Image"] retain];  

//Creating a file at this path
NSFileManager *fileManager = [NSFileManager defaultManager]; 
BOOL ok = [fileManager createFileAtPath:dataFilePath contents:nil attributes:nil];
if (!ok) {
    NSLog(@"Error creating file %@", dataFilePath);
} 
else {
    //Writing image to the created file
    NSFileHandle *myFileHandle = [NSFileHandle fileHandleForWritingAtPath:imagePath];

    [myFileHandle writeData:UIImageJPEGRepresentation(imageView.image, 1.0)];
    [myFileHandle closeFile];
}

NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
if (userDefaults) {

    [userDefaults setObject:imagePath forKey:@"ImagePath"];

}

//Retrieving
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
NSString *imagePath = [userDefaults objectForKey:@"ImagePath"];
NSFileHandle* fileHandle = [NSFileHandle fileHandleForReadingAtPath:dataFilePath];
UIImage* loadedImage = [UIImage imageWithData:[fileHandle readDataToEndOfFile]];

Method of saving text to NSUserDefaults:

//Saving
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
[userDefaults setValue:textView.text forKey:@"Text"];

//Retrieving
textView.text = [userDefaults valueForKey:@"Text"];
