iOS添加自訂自體 [UIFont fontWithName: size:]

1.添加對應的自體檔案（.ttf或.otf等）到工程目錄下，比如：SIMKAI.TTF

2.在-info.plist檔案中添加一項Fonts provided by application，item0對應的value為SIMKAI.TTF，多個自體依次添加即可。

3.使用 [UIFont fontWithName: size:]來設定自體，fontWithName的參數不一定是SIMKAI，這個字型名字需要別的方法去查。

查字型名字方法如下：

    for(NSString *familyName in [UIFont familyNames])    {           NSLog(@"familyName = %@", familyName);                for(NSString *fontName in [UIFont fontNamesForFamilyName:familyName])        {               NSLog(@"\tfontName = %@", fontName);        }    }

在上面第2步添加前和添加後的情況下分別執行如上代碼，把控制台列印出的資訊分別做記錄。

控制台列印資訊樣本：

用比較檔案的方法找出2次從控制台列印出的資訊的不同內容，這些不同的內容就是新添加進去的字型的名字。

從而可以看出，新添加進去的自體的名字就是 KaiTi_GB2312

設定自體的時候就應該如下操作：

[UIFont fontWithName:@"KaiTi_GB2312" size:20.0]
