Question

I am stuck at a simple task, I have uilabel on my uiviewcontroller’s interface file. I want to update that label via some methods. It doesn’t update the label.

.h
UIViewController
{
  UILabel *pictureNameLabel;
}
@property (nonatomic, strong) IBOutlet UILabel *pictureNameLabel;

.m
@synthesize pictureNameLabel=_pictureNameLabel;
- (void)viewDidLoad
{
        _pictureNameLabel = [[UILabel alloc] init];
        _pictureNameLabel.textColor=[UIColor blackColor];
        _pictureNameLabel.text=@"Try";
}

How can I fix that issue?

You don’t need to alloc the label. It’s already alive and get’s awaken from the nib.

.h
UIViewController
{
  //UILabel *pictureNameLabel;
}
@property (nonatomic, strong) IBOutlet UILabel *pictureNameLabel;

.m
@synthesize pictureNameLabel=_pictureNameLabel;
- (void)viewDidLoad
{
        //_pictureNameLabel = [[UILabel alloc] init];
        _pictureNameLabel.textColor=[UIColor blackColor];
        _pictureNameLabel.text=@"Try";
}
