ios 在项目中使用文字ttf文件

1.把test.ttf文件添加到工程中

2.在info.plist中添加Fonts provided by application（数组类型），数组中添加item   test.ttf 

 ps:

获取ttf字体名称

法1.遍历所有字体名称找到对应的

    for( NSString *familyName in [UIFont familyNames] ){  
        NSLog( "Family: %s ", [familyName UTF8String] );  
        for( NSString *fontName in  [UIFont fontNamesForFamilyName:familyName] ){  
            NSLog( " Font: %s ", [fontName UTF8String] );  
        }  
    }

法2.通过读取本地文件路径

　　 NSString *path = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"ttf"];

    NSURL *fontUrl = [NSURL fileURLWithPath:path];

    CGDataProviderRef fontDataProvider = CGDataProviderCreateWithURL((__bridge CFURLRef)fontUrl);

    CGFontRef fontRef = CGFontCreateWithDataProvider(fontDataProvider);

    CGDataProviderRelease(fontDataProvider);

    CTFontManagerRegisterGraphicsFont(fontRef, NULL);

    NSString *fontName = CFBridgingRelease(CGFontCopyPostScriptName(fontRef));

    CGFontRelease(fontRef);
