Exception while Assign Custom font

I am trying to add custom font in my application


I added the
file in my project and in
I added Fonts provided by the application and added to target membership. Now when I assign the font through Interface it works perfectly when I try to add it in
I get the below exception

Terminating app due to uncaught exception
'NSInvalidArgumentException', reason: '* -[__NSPlaceholderDictionary

My code is

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.alignment = _lbl_mylabel.textAlignment;

NSDictionary *attribs = @{
NSForegroundColorAttributeName: self.lbl_ticketdetail.textColor,
NSFontAttributeName: self.lbl_ticketdetail.font
NSMutableAttributedString *attributedText =
[[NSMutableAttributedString alloc] initWithString:text
paragraphStyle.lineSpacing = 3;

[attributedText setAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"GothamPro-NarrowMedium" size:20.0],NSParagraphStyleAttributeName:paragraphStyle}

NSRange plce = [text rangeOfString:place];
[attributedText setAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"GothamPro-NarrowMedium" size:16.0],NSParagraphStyleAttributeName:paragraphStyle}

NSMutableParagraphStyle *paragraphStyle1 = [[NSMutableParagraphStyle alloc] init];
paragraphStyle1.lineSpacing = 1;
NSRange tkt_num_range = [text rangeOfString:STR_tkt_num_club];
[attributedText setAttributes:@{NSFontAttributeName:[UIFont fontWithName:@"GothamMedium" size:13.0],NSParagraphStyleAttributeName:paragraphStyle1} range:tkt_num_range];
self.mylabel.attributedText = attributedText;

Crash occurred due to Attempting to insert null object to Dictionary.

I think you have problem with adding custom font to your project.

Please re-check

  1. Add .TTF font in your application.
  2. Add the key Fonts provided by application to a new row and add each .TTF file names.

After this steps, I guess your info.plist may like this:


When I set custom fonts via Storyboard, above steps are NOT needed for me!
