1.将准备好的字体文件加入项目中

2.打开Build Phases—Copy Bundle Resources，确保刚添加的字体文件在列表中，否则需要手动加到这里

3.编辑”项目名-Info.plist”文件
（1）addRow—Fonts provided by application

（2）将加入的字体名连同扩展名填在这里

4.在Mac下双击字体文件，在标题栏中找到字体的fontName

5.打印出系统所有的字体名

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 is %@", [fontNames objectAtIndex:indFont]);
        }
        [fontNames release];
    }
    [familyNames release];

6.这样就可以使用了[UIFont fontWithName:@"chenweixun-yingxing" size:20];

7.只有文件里配的字才会转换。
