This is how I do it.. I’m copying and pasting my code so there’s some additional functionality.

// image is a UIImage
// inputText is the user selected imagename
// date is a string I inserting to make pictures a unique identifier (i.e. no duplicate names)
NSData *imageData1 = UIImageJPEGRepresentation(image, 1.0);
NSString *imageFilename = [NSString stringWithFormat:@"%@-%@.jpg", inputText,date];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *path = [NSString stringWithFormat:@"%@/%@", [paths objectAtIndex:0], imageFilename];

if([imageData1 writeToFile:path atomically:YES]){
    NSLog(@"Write to Document folder success filename = %@",path);
}
