Adding a subview to another subview is not working

Question

I am trying to add label (headerLabel) to another subview (introPadTutorial) here and it is not showing up on the screen. Can some please help me where am I making mistake?

//Header file

@property (nonatomic, retain) UIView *introPadTutorial;

//Implementation file

@synthesize introPadTutorial;

UIView *v = [_appDelegate getCurrentView];
CGRect tutorialFrame = [self getTableViewFrame];

introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(v.frame.size.width, 80, -tutorialFrame.size.width, v.frame.size.height)];
[introPadTutorial setBackgroundColor:[UIColor uberLightGray]];
[introPadTutorial setUserInteractionEnabled:YES];

UILabel *headerLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 180, 180)];
[headerLabel setText:@"test test test"];
[headerLabel setBackgroundColor:[UIColor greenColor]];
[headerLabel setFont:[UIFont boldSystemFontOfSize:16.0f]];
[headerLabel setTextColor:[UIColor redColor]];
[headerLabel setShadowColor:[UIColor whiteColor]];
[headerLabel setShadowOffset:CGSizeMake(0, 1)];

[self.introPadTutorial addSubview:headerLabel];
[headerLabel release];

[v addSubview:introPadTutorial];
[introPadTutorial release];

Answer 1

Is your introPadTutorial view showing up? You have a negative width in it's initWithFrame call.

Answer 2

May be your...

introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(v.frame.size.width, 80, -tutorialFrame.size.width, v.frame.size.height)];

should actually be...

introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(0, 80, tutorialFrame.size.width, v.frame.size.height)];

Answer 3

Don't use a negative width to change the POSITION, use the origin to change the position.

Use this:

introPadTutorial = [[UIView alloc] initWithFrame:CGRectMake(v.frame.size.width - tutorialFrame.size.width, 80, tutorialFrame.size.width, v.frame.size.height)];

I think that should help make the subview actually show up.
