Adding Custom Fonts in ios

1) Add the .TTF or .OTF font file/s you wish to use as a resource

2) Open your info.plist and create a new key called UIAppFonts(Fonts provided by application), set the key to be an array type.

3) For each font you want to use in your app, add it as a new object in the array with its full name and extension and save the info.plist when finished

4) Now in your code you can simply call

[UIFont fontWithName:@”Insert font name here” size:18]

}

– (void)dealloc
