想單獨指定某段文本字體類型，但是sdk文檔中似乎沒有iphone可用字體列表 ，找到一種方法，可以查看當前sdk可用字體類型

[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];
