Setting BOLD font on iOS UILabel

I have assigned a custom font of 'Helvetica' with size 14 already for the text in UILabel using Interface Builder.

I am using reusing the same label at multiple places, but at some place I have to display the text in bold.

Is there any way I can just specify to make the existing font bold instead of creating the whole UIFont again? This is what I do now:

myLabel.font = [UIFont fontWithName:@"Helvetica Neue" size:14];

Answer Source
myLabel.font = [UIFont fontWithName:@"Helvetica-Bold" size:14];

If you wanna set it programmatically,you must check bold type is support or not in iOS, normally Bold or Italic will have format FontName-Bold, FontName-Italic, FontName-BoldItalic.

Now, write a bold function

-(void)boldFontForLabel:(UILabel *)label{
    UIFont *currentFont = label.font;
    UIFont *newFont = [UIFont fontWithName:[NSString stringWithFormat:@"%@-Bold",currentFont.fontName] size:currentFont.pointSize];
    label.font = newFont;

Then call it

[self boldFontForLabel:yourLabel];
