TTStyleSheet with span class

I am making an app with Three20. I have a TTTableViewController that is the main catalog for other screens and a secont TTViewController connected with a tturl scheme.

In my TTViewController there is a TTStyledTextLabel connected to a UIScrollView, that displays a chunk of text from a database that has span, p with classes.

I have defined those classes in an TTStyleSheet subclass that is instantiated just like in TTCatalog example.

The problem is, that even though in my TTTableViewController the stylesheet works, in the TTViewController it doesn't.

I have defined my TTViewController loadView as the following:

- (void)loadView {

[super loadView];

FMDBDataAccess *dba = [[[FMDBDataAccess alloc] init] autorelease];

Definition *def = [dba getDefinition:termId];

NSLog(@"%@ ",def.term);

self.title = def.term;

NSString *s = def.definition;

TTStyledTextLabel* label1 = [[[TTStyledTextLabel alloc] initWithFrame:CGRectMake(10, 10, self.view.bounds.size.width-20, self.view.bounds.size.height-20)] autorelease];

label1.font = [UIFont fontWithName:@"PFIndex Black" size:15];

label1.text = [TTStyledText textFromXHTML:s lineBreaks:YES URLs:YES];

label1.contentInset = UIEdgeInsetsMake(10, 10, 10, 10);

[label1 sizeToFit];

CGFloat height = label1.height;



CGRect scrollViewFrame = CGRectMake(0, 0, 320, 440);

sv = [[UIScrollView alloc] initWithFrame:scrollViewFrame];

[self.view addSubview:sv];



CGSize scrollViewContentSize = CGSizeMake(320, ceil(height));

[sv setContentSize:scrollViewContentSize];

[sv addSubview:label1];

}

Also, in my -initWithTermId:(int)termId:

- (id)initWithTermId:(int)tid {

if (self = [super init]) {

    [TTStyleSheet setGlobalStyleSheet:[[[CustomStyleSheet alloc] init] autorelease]];

    termId = tid;

}

return self;

}

Where CustomStyleSheet is the subclassed TTStyleSheet. Am I using the right UI Control for styling my text? Is there another one to use?
