1 Add your custom font into your project , i.e. Dragged the font file(CALIBRIZ_0.TTF) into XCode project.
2 Edit Info.plist: Add a new entry with the key "Fonts provided by application".
3 For each of your files, add the file name to this array
4.Opened the font in font book(double click on your font in finder) to see what the real filename is and I see this:
Now set font to your label
yourLabel.font = [UIFont fontWithName:@"Calibri" size:15];
