UILabel font size?

Question

I can't seem to modify the font size of a UILabel with the following code:

itemTitle.font = [UIFont systemFontOfSize:25];

As i increase the number 25 to something greater, it seems to only add a top margin to the label, which consequently pushes the text down so much, so that the text gets cut off at the bottom or completely overflows.

i have another UILabel elsewhere with systemFontOfSize 25, and it's much smaller than the itemTitle text. What's going on? Isn't 25 supposed to be an absolute value?

i am so confused on how to programmatically change font size of uilabels.

Solution 1

Check that your labels aren't set to automatically resize. In IB, it's called "Autoshrink" and is right beside the font setting. Programmatically, it's called adjustsFontSizeToFitWidth.

Solution 2

I have modified the UILabel by following code:

label.font=[label.font fontWithSize:25];

Try this and see whether is it working in your case or not???

Solution 3

[label setFont:[UIFont systemFontOfSize:9]];

this works for me.

Solution 4

For Swift 3.1, Swift 4 and Swift 5, if you only want change the font size for a label :

let myLabel : UILabel = ...
myLabel.font = myLabel.font.withSize(25)

Solution 5

**You can set font size by these properties **

timedisplayLabel= [[UILabel alloc]initWithFrame:CGRectMake(70, 194, 180, 60)];

[timedisplayLabel setTextAlignment:NSTextAlignmentLeft];

[timedisplayLabel setBackgroundColor:[UIColor clearColor]];

[timedisplayLabel setAdjustsFontSizeToFitWidth:YES];

[timedisplayLabel setTextColor:[UIColor blackColor]];

[timedisplayLabel setUserInteractionEnabled:NO];

[timedisplayLabel setFont:[UIFont fontWithName:@"digital-7" size:60]];

timedisplayLabel.layer.shadowColor =[[UIColor whiteColor ]CGColor ];

timedisplayLabel.layer.shadowOffset=(CGSizeMake(0, 0));

timedisplayLabel.layer.shadowOpacity=1;

timedisplayLabel.layer.shadowRadius=3.0;

timedisplayLabel.layer.masksToBounds=NO;

timedisplayLabel.shadowColor=[UIColor darkGrayColor];

timedisplayLabel.shadowOffset=CGSizeMake(0, 2);
