iOS Font

1. 非常棒的查看字体样貌网站: http://iosfonts.com

     1. 查看设备支持字体: 

        NSArray *familyNames = [NSMutableArray arrayWithArray:[UIFont familyNames]];

     1. 需要导入第三方字体库link? 有些字库可以从OS X中导入 https://support.apple.com/en-hk/HT201375

     1. 导入第三方库，将.otf加入bundle中,配置info.plist Fonts 'provided by application'字段。例如AppleSDGothicNeo-Medium.otf添加进bundle中，则需要在info.plist中添加此,font name便是AppleSDGothicNeo-Medium。检测字库是否被导入:例如应用中用到的所有字库，其实这些字体系统都有

         UIFont *font1 = [UIFont fontWithName:@"Avenir-Roman" size:12];

         UIFont *font2 = [UIFont fontWithName:@"Helvetica Neue" size:12];

         UIFont *font3 = [UIFont fontWithName:@"HelveticaNeue-Medium" size:12];

         UIFont *font4 = [UIFont fontWithName:@"AppleSDGothicNeo-Regular" size:12];

         UIFont *font5 = [UIFont fontWithName:@"AppleSDGothicNeo-Medium" size:12];

         UIFont *font6 = [UIFont fontWithName:@"AppleSDGothicNeo-SemiBold" size:12];

         UIFont *font7 = [UIFont fontWithName:@"AppleSDGothicNeo-Bold" size:12];

         UIFont *font8 = [UIFont fontWithName:@"AppleSDGothicNeo-UltraLight" size:12];
