Obj-C: [__NSArrayI length]: unrecognized selector sent to instance - ios

Question

I'm trying to pass data from an NSMutableArray to an NSDictionary. It seems I do this successfully, however XCode throws me a crash when trying to display the passed data in self.username.text. Any idea why this is and how I can fix it? See code below.
ViewController.m
-(void)calloutTapped:(UITapGestureRecognizer *) sender
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"Main" bundle:nil];
OtherUserViewController *yourViewController = (OtherUserViewController *)[storyboard instantiateViewControllerWithIdentifier:#"OtherUserViewController"];
NSDictionary *dictionary = [[NSDictionary alloc] init];
dictionary = [self.addressData mutableCopy];
yourViewController.mapuserData = dictionary;
[self.navigationController pushViewController:yourViewController animated:YES];
}
OtherUserViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
if (self.mapuserData != NULL) {
NSLog(#"This is map user data %#", self.mapuserData);
self.addFriend.hidden = NO;
self.username.text = self.mapuserData[#"users_name"];
NSLog(#"THIS IS IT %#", self.mapuserData[#"users_name"]);
self.userBio.text = self.mapuserData[#"userbio"];
NSString *thirdLink = self.mapuserData[#"photo_path"];
NSString *ImageURLTwo = thirdLink;
NSData *imageDataTwo = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURLTwo]];
self.userPhoto.image = [[UIImage alloc] initWithData:imageDataTwo];
}
if (neighbourDetail == NULL) {
self.addFriend.hidden = YES;
self.username.text = [self.myFriendData objectForKey:#"node_title"];
NSLog(#"this is friend detail %#", self.myFriendData);
self.userBio.text = [self.myFriendData objectForKey:#"body"];
NSString *thirdLink = [self.myFriendData objectForKey:#"friendphoto"];
NSString *ImageURLTwo = thirdLink;
NSData *imageDataTwo = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURLTwo]];
self.userPhoto.image = [[UIImage alloc] initWithData:imageDataTwo];
} else {
self.addFriend.hidden = NO;
self.username.text = [neighbourDetail objectForKey:#"first name"];
NSLog(#"this is neighbour detail %#", neighbourDetail);
self.userBio.text = [neighbourDetail objectForKey:#"userbio"];
NSString *secondLink = [neighbourDetail objectForKey:#"photo_path"];
NSString *ImageURL = secondLink;
NSData *imageData = [NSData dataWithContentsOfURL:[NSURL URLWithString:ImageURL]];
self.userPhoto.image = [[UIImage alloc] initWithData:imageData];
}
NSString *testing = [self.myFriendData objectForKey:#"node_title"];
NSLog(#"This is the testing value %#", testing);
NSArray *friendorNo = self.checkfriendData;
NSLog(#"Friend or No Value %#", friendorNo);
for (NSDictionary *dict in friendorNo) {
if ([dict[#"node_title"] isEqualToString:testing]) {
self.addFriend.hidden = YES;
}
}
Logged data passed succesfully to self.mapuserData:
2017-06-14 22:03:49.397526-0700[3706:1178771] This is user data (
{
address = "2957 chill street";
childrenunder = Yes;
city = Vancouver;
"emergency facility" = None;
"first name" = josh;
"last name" = tree;
phone = 688;
"photo_path" = "x.png";
"points balance" = 24;
"postal code" = b6b6v5;
"profile photo" = "<null>";
"property type" = Apartment;
province = ont;
"special skills" = "None";
"star rating" = 0;
"street_address" = none;
supervision = Yes;

userbio = nfkkdkckmfkekxkx;

}

Answer 1

You are accessing an array.
Can you try this:
_username.text = [self.mapuserData firstObject][#"users_name"]
So, basically self.mapUserContent is an array of dictionary. What we did is get the first object and from the first object we get the username.
let me know if this works

Answer 2

You are trying to call objectForKey: for NSArray object.
self.addressData is a kind of NSArray
FIX:
NSDictionary *dictionary = [[NSDictionary alloc] init];
dictionary = [[self.addressData firstObject] mutableCopy];
yourViewController.mapuserData = dictionary;
