I have a UILabel which I set a font size and a font name with Interface Builder. Now I have to read the values of both in my ViewController.

How can I do this?

This method has been deprecated iOS7, take a look at this article #19129297 – Chloral 17/10, 2014 at 17:41

Add a property to your view controller's .h file:

@property (nonatomic, retain) IBOutlet UILabel *label;

Link the label to this IBOutlet under "File's Owner" outlets in Interface Builder. If not using ARC, make sure you release it in -dealloc

- (void)dealloc
{
    [self.label release];
    [super dealloc];
}

Then to get the font name and size all you need is

NSString *fontName = self.label.font.fontName;
CGFloat fontSize = self.label.font.pointSize;

Does not work. I can write text in it, but the fontName and pointSize is null. – Yalu 2/2, 2011 at 9:18

Do you mean that you can programmatically change the text of the label, but you can't access the fontName and pointSize? I edited the above answer to include self.label, instead of just label, since I didn't mention creating an instance variable for label. – Safranine 2/2, 2011 at 14:36

Also, make sure you've hooked up the label in Interface Builder with the IBOutlet you made in File's Owner (the view controller). – Safranine 2/2, 2011 at 14:40

Ah, I forgot the connection in IB with the File's Owner. – Yalu 3/2, 2011 at 7:18

Swift:

var currentFontSize = button.titleLabel?.font.pointSize

They could have named it font.size whats up with pointSize. When you are creating font you use size UIFont(name: ..., size: ...) – Tranquil 16/1, 2022 at 15:27

Pointsize value is not the Font Size of used in UIFont size property. Say if you go set interface builder font size to 14 and do a print of the pointSize you'll get only 11.

Seems to be working now. If i set the font size of a label in the interface builder / storyboard editor to 17... myLabel.font.pointSize returns 17. – Provisional 13/1, 2017 at 0:10

you have to attach it to a UILabel IBOutlet, and then, label.font...
