（iPhone/iPad开发）在iOS系统中动态设置文本字体

想单独指定某段文本字体类型，但是sdk文档中似乎没有iphone可用字体列表，找到一种方法，可以查看当前sdk可用字体类型

[cpp]
NSArray *familyNames = [[NSArray alloc] initWithArray:[UIFont familyNames]];
    NSArray *fontNames;
    NSInteger indFamily, indFont;
    for (indFamily=0; indFamily<[familyNames count]; ++indFamily)
    {
        NSLog(@"Family name: %@", [familyNames objectAtIndex:indFamily]);
        fontNames = [[NSArray alloc] initWithArray:
                     [UIFont fontNamesForFamilyName:
                      [familyNames objectAtIndex:indFamily]]];
        for (indFont=0; indFont<[fontNames count]; ++indFont)
        {
            NSLog(@"    Font name: %@", [fontNames objectAtIndex:indFont]);
        }
        [fontNames release];
    }
    [familyNames release];

sdk3.0下输出字体列表是：
