UILabel not visually refreshing - iphone

Question

The Problem
I have a UILabel buried in a few layers of subviews and I can't seem to change it's text. The code to update the label is inMyCardSubclass's updateVisualElements method. The really weird thing is that when I log the description of these labels, the text has been updated, but it is not visible. Here's what it looks like:
Inside my View Controller's viewDidLoad method I initialize a UIScrollView and my card object. I add its cardView as a subview like so:
-(void)viewDidLoad
{
[super viewDidLoad];
MyCardSubclass *myCard = [[MyCardSubclass alloc]initWithInfo:info andPoint:CGPointMake(5, runningYValue)];
[myCard setParentViewController:self];
[scrollView addSubview:[myCard cardView]];
//Resize scrollView contentSize
}
My Card
//header
#property (nonatomic, strong) UIView *contentView;
#property (nonatomic, strong) UIView *cardView;
#property (nonatomic, strong) CardInfo *cardInfo;
#property (nonatomic, strong) UIViewController *parentViewController;
//implementaion
-(UIView *)cardView
{
CGRect screenRect = [[UIScreen mainScreen] bounds];
UIView *toReturn = [[UIView alloc]initWithFrame:CGRectMake(self.point.x,self.point.y, screenRect.size.width-borderOffset*2, cardViewHeight)];
UILabel *titleLabel = [[UILabel alloc]initWithFrame:CGRectMake(borderOffset, 0, toReturn.frame.size.width-borderOffset*2, titleHeight)];
[titleLabel setText:self.title];
[toReturn addSubview:titleLabel];
[self.contentView setFrame:CGRectMake(borderOffset, titleHeight, screenRect.size.width-borderOffset, contentViewHeight)];
if(self.contentView)
[toReturn addSubview:self.contentView];
else
NSLog(#"no contentView");
//other view stuff
return toReturn;
}
My Card Subclass
//header
#property(nonatomic, strong) UILabel *totalAmountLabel;
#property(nonatomic, strong) UILabel *availableAmountLabel;
#property(nonatomic, assign) double available;
//implementation
-(UIView *)cardView
{
[self setContentView:[self contentViewFromCardInfo:self.cardInfo]];
return [super cardView];
}
-(UIView *)contentViewFromCardInfo:(CardInfo *)cardInfo
{
UIView *toReturn = [[UIView alloc]init];
NSString *amount = #"0";
self.totalAmountLabel = [[UILabel alloc]initWithFrame:CGRectMake(labelWidth,
runningYValue,
labelWidth,
labelHeight)];
[self.totalAmountLabel setText:amount];
[toReturn addSubview:self.totalAmountLabel];
runningYValue +=self.totalAmountLabel.frame.size.height+spacer;
self.availableAmountLabel = [[UILabel alloc]initWithFrame:CGRectMake(labelWidth,
runningYValue,
labelWidth,
labelHeight)];
[self.availableAmountLabel setText:#"0"];
[toReturn addSubview:self.availableAmountLabel];
return toReturn;
}
-(void)updateVisualElements
{
NSString *amount = #"10"
NSString *availableString = #100"
//The log descriptions for these labels are okay.
[self.totalAmountLabel setText:amount];
NSLog(#"%#",self.totalAmountLabel.debugDescription);
[self.availableAmountLabel setText:availableString];
NSLog(#"%#",self.availableAmountLabel.debugDescription);
NSAssert([NSThread isMainThread], #"Not on main thread");
NSAssert(self.totalAmountLabel, #"No label");
}
What I've tried
Calling [self.totalAmountLabel setNeedsDisplay] after setting the text
Calling the method on the main thread using [self.totalAmountLabel performSelector:#selector(setText:) withObject:amount afterDelay:0.0]

Answer 1

You can try one thing, Use Tag property to get the added Label and change its contends
Example:
UILabel totalAmountLabel = [[UILabel alloc]initWithFrame:CGRectMake(labelWidth,
runningYValue,
labelWidth,
[totalAmountLabel setText:amount];
totalAmountLabel.tag = 100;
[toReturn addSubview:totalAmountLabel];
Then in your updateVisualElements()
UILabel *tempTotalAmountLabel = (UILabel *)[self.view viewWithTag:100];
[tempTotalAmountLabel setText:amount];

Answer 2

Fixed it! The problem wasn't actually in my attempts to set the label or draw its view.
I wasn't using my initializers properly to init my content view only once.
I removed this override in my subclass
-(UIView *)cardView
{
[self setContentView:[self contentViewFromCardInfo:self.cardInfo]];
return [super cardView];
}
I also took the code from the -(UIView *)cardView method in my superclass and put into a -(UIView *)buildCardView method and rewrote the cardView property accessor to what it should have been.
-(UIView *)cardView
{
if(!_cardView)
_cardView = [self buildCardView];
return _cardView;
}
