How to change the height of a label during execution?

Question

This sounds simple, maybe I am missing something. I have four labels that I am using in a bar graph style. I want to change the height when the button is pressed to change the height of the label and make the bar graph look properly.

In my header for the labels I have:

@property (weak, nonatomic) IBOutlet UILabel *transBar;

I have been trying to use the following line of code in the method for the button action:

//Update the height of the bar graphs.

self.transBar.frame = CGRectMake(133, 283, 100, 200); //200 will be replaced with a variable when working.

When I test this I can not get the height to change despite how simple this seems. On the XIB in the size inspector I can easily change the value from 400 to 200 and it moves exactly how I want. I just can not get this to happen in runtime. Any help appreciated. Thanks guys.

How do you set the label on storyboard, are you using autolayout?

try that, let's see:

self.transBar.frame.size.height=200;
