iOS, NSString property confused as being UITextField

Question

@interface HuntProfileView : UIViewController
@property (strong, nonatomic) NSString *huntgroupTitle;
@property (strong, nonatomic) NSString *huntgroupId;
@property (strong, nonatomic) NSArray *lines;
@end

@interface HuntProfileView ()
@property (weak, nonatomic) IBOutlet UITextField *huntgrouptitleText;
@property HuntLineTable *childView;
@end

@implementation HuntProfileView

- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"huntgroupTitle %@", self.huntgroupTitle);
    self.huntgrouptitleText.text = self.huntgroupTitle;
}

^{
    HuntProfileView *viewController = [self.storyboard instantiateViewControllerWithIdentifier:@"HUNTVIEW"];
    viewController.huntgroupId = huntId;
    viewController.huntgroupTitle = title;
    [self.navigationController pushViewController:viewController animated:YES];
 }

viewController.huntgroupTitle = title; is correct, or at least title is the string as expected.

The NSLog in .m outputs as:

2015-01-21 09:47:42.267 changeView[1108:16196] huntgroupTitle <UITextField: 0x7fa9a8fc8480; frame = (16 63; 568 30); text = ''; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; layer = <CALayer: 0x7fa9a8fc9c70>>
2015-01-21 09:47:42.267 changeView[1108:16196] -[UITextField rangeOfCharacterFromSet:]: unrecognized selector sent to instance 0x7fa9a8fc8480
2015-01-21 09:47:42.270 changeView[1108:16196] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UITextField rangeOfCharacterFromSet:]: unrecognized selector sent to instance 0x7fa9a8fc8480'

I'm able to get successful execution when assigning self.huntgroupTitle a literal string ("hello, world"). Debugging has shown that at instantiation, both the input string of title as well as viewController.huntgroupTitle are confirmed to be the correct type.

Answer 1

While initialising the HuntProfileView you must be assigning a UITextField to huntgroupTitle . Please check that.

I guess you might be doing something like this

HuntProfileView *huntV = [[HuntProfileView alloc] init];
huntV.huntgroupTitle = **some UITextField**;

instead it should be

HuntProfileView *huntV = [[HuntProfileView alloc] init];
huntV.huntgroupTitle = someTextField.text;

Please check. Thanks

The Storyboard source file had:

<connections>
  <outlet property="huntgroupTitle" destination="wx0-NH-iGn" id="P9H-Oe-AEm"/>
  <outlet property="huntgrouptitleText" destination="wx0-NH-iGn" id="Z1E-9e-lEn"/>
</connections>

Removing line with property "huntgroupTitle" resolved this
