UILabel not updating connected with IBOutlet - iphone

Question

I am trying to update the UILabel of IBOutlet, however for some reason the content is not getting updated. Initially, the content is getting loaded from the model, which performs jsonResponse in async. However, I have set a delegate once the content is there to update the layout for which I am calling setNeedsDisplay.
Any help here would be appreciated.
Thanks.
The code below:
#interface pd ()
#property (nonatomic,retain) NSDictionary *pD;
#property (nonatomic, retain) pd_model *pdModel;
#end
#implementation pd
#synthesize pD = _pD, pdModel;
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil :(NSDictionary*)pD {
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
self.productDetails = [[NSDictionary alloc] initWithDictionary:pD];
self.pdModel = [[ProductDetails_Model alloc] init:pD];
self.pdModel.delegate = self;
NSLog(#"%#",[self.pD description]);
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)];
[scrollView setBackgroundColor:[UIColor clearColor]];
[self.view addSubview:scrollView];
scrollView.showsHorizontalScrollIndicator = YES;
scrollView.scrollEnabled = YES;
// Do any additional setup after loading the view from its nib.
productRecCarousel = [[iCarousel alloc] initWithFrame:CGRectMake(0.0f, scrollView.contentSize.height, 320.0f, 100.0)];
productRecCarousel.delegate = self;
[scrollView addSubview:productRecCarousel];
[self addProductDescription];
NSLog(#"%#",[self.pdModel responseCode]);
[soldBy setText:[self.pdModel responseCode]];
//[soldBy setText:#"1"];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
// e.g. self.myOutlet = nil;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

return 150;

}
- (void)addProductDescription {
NSLog(#"%f",addProductDetails.frame.size.height);
addProductDetails.frame = CGRectMake(0.0f, productRecCarousel.frame.size.height, addProductDetails.frame.size.width, addProductDetails.frame.size.height);
[scrollView addSubview:addProductDetails];
}
- (void)updateTheLayout {
//[self.view setNeedsDisplay];
//This is where I get the delegate called once the model is being updated. I tried scrollView and self.view setNeedsDisplay and setNeedsLayout but the IBoutlet never gets updated which is in "ViewDidLoad as assigned as" : [soldBy setText:[self.pdModel responseCode]];
}
Thanks.

Answer 1

so you just have to call [soldBy setText:[self.pdModel responseCode]]; from updateTheLayout and not from viewDidLoad because it is not ready yet. And please make sure to update the UI elements from the main thread.

Answer 2

You have to call [soldBy setText:[self.pdModel responseCode]]; in your callback, not in the viewDidLoad method.
