iOS添加自定義自體 [UIFont fontWithName: size:]

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

2.在-info.plist文件中添加一項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:]來設置自體，fontWithName的參數不一定是SIMKAI，這個字體名字需要別的方法去查。

查字體名字方法如下：

1. for(NSString *familyName in [UIFont familyNames])
2. {
3. NSLog(@"familyName = %@", familyName);
5. for(NSString *fontName in [UIFont fontNamesForFamilyName:familyName])
6. {
7. NSLog(@"\tfontName = %@", fontName);
8. }
9. }

控制台打印信息示例：

1. 2012-08-08 14:27:56.150[1821:c07] familyName = Thonburi
2. 2012-08-08 14:27:56.153[1821:c07] fontName = Thonburi-Bold
3. 2012-08-08 14:27:56.154[1821:c07] fontName = Thonburi
4. 2012-08-08 14:27:56.154[1821:c07] familyName = Snell Roundhand
5. 2012-08-08 14:27:56.154[1821:c07] fontName = SnellRoundhand-Bold
6. 2012-08-08 14:27:56.155[1821:c07] fontName = SnellRoundhand-Black
7. 2012-08-08 14:27:56.155[1821:c07] fontName = SnellRoundhand
8. 2012-08-08 14:27:56.156[1821:c07] familyName = Academy Engraved LET
9. 2012-08-08 14:27:56.156[1821:c07] fontName = AcademyEngravedLetPlain
10. 2012-08-08 14:27:56.157[1821:c07] familyName = Marker Felt
11. 2012-08-08 14:27:56.157[1821:c07] fontName = MarkerFelt-Wide
12. 2012-08-08 14:27:56.158[1821:c07] fontName = MarkerFelt-Thin
13. 2012-08-08 14:27:56.158[1821:c07] familyName = Geeza Pro
14. 2012-08-08 14:27:56.159[1821:c07] fontName = GeezaPro-Bold
15. 2012-08-08 14:27:56.159[1821:c07] fontName = GeezaPro
16. 2012-08-08 14:27:56.182[1821:c07] familyName = Arial Rounded MT Bold
17. 2012-08-08 14:27:56.183[1821:c07] fontName = ArialRoundedMTBold
18. 2012-08-08 14:27:56.183[1821:c07] familyName = Trebuchet MS
19. 2012-08-08 14:27:56.184[1821:c07] fontName = TrebuchetMS
20. 2012-08-08 14:27:56.184[1821:c07] fontName = TrebuchetMS-Bold

用比較文件的方法找出2次從控制台打印出的信息的不同內容，這些不同的內容就是新添加進去的字體的名字。

從而可以看出，新添加進去的自體的名字就是 KaiTi_GB2312

設置自體的時候就應該如下操作：

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