The error means you are trying to put nil
in the dictionary (which is not allowed). Since you are building the dictionaries with string literals those can't be nil
. This means the problem is with one or more of your images.
Try this to help find the problem:
+(NSArray *)users
{
UIImage *image1 = [UIImage imageNamed:@"person1.jpeg"];
UIImage *image2 = [UIImage imageNamed:@"person2.jpeg"];
UIImage *image3 = [UIImage imageNamed:@"person3.jpeg"];
UIImage *image4 = [UIImage imageNamed:@"person4.jpeg"];
NSDictionary *user1 = @{@"username" : @"master photographer", @"email" : @"worldtravel@me.com", @"password" : @"drowssap", @"age" : @24, @"profilePicture" : image1 };
NSDictionary *user2 = @{@"username" : @"Lots of tots", @"email" : @"otterskips@me.com", @"password" : @"icecreamrocks", @"age" : @65, @"profilePicture" : image2 };
NSDictionary *user3 = @{@"username" : @"iTechie", @"email" : @"theRealApple@me.com", @"password" : @"infiniteloop", @"age" : @30, @"profilePicture" : image3 };
NSDictionary *user4 = @{@"username" : @"Royal", @"email" : @"king@me.com", @"password" : @"IGotAPalace", @"age" : @0, @"profilePicture" : image4 };
NSArray *userArray = @[user1, user2, user3, user4];
return userArray;
}
Now you can either use the debugger and see if image1
, image2
, image3
, or image4
is nil
or add NSLog
statements for each.
Keep in mind that filenames are case sensitive so be sure the name you pass to imageNamed:
exactly matches the real filename. Also verify the images have the extension jpeg
and not jpg
. Make sure the images are being packaged in your resource bundle.
