iPhone开发How-to：列出iPhone上可用的字体

iPhone上的系统字体在很多场合都可以满足要求了。你可以通过系统提供的字体类方法轻松地在普通、加粗和斜体之间选择。示例代码如下：

UIFont *mainTitleFont = [UIFont boldSystemFontOfSize:14.0];

UIFont *subTitleFont = [UIFont SystemFontOfSize:14.0];

UIFont *textFont = [UIFont italicSystemFontOfSize:12.0];

但如果要一个加粗斜体或者其他字体怎么办呢？在这种情况下，你可以按如下使用fontWithName方法：

UIFont *altFont = [UIFont fontWithName:@"Courier-Bold" size:14.0];

这很好，不过你如何知道可用的字体名字呢？如果你猜错了字体名字，你的代码会抛出异常——这里可没有映射到最接近字体的优雅处理！

在iPhone文档上我无法找到可用的字体名字，在网络上搜索的时候也无果（至少在搜索结果的前几页）。所以我写了如下一段代码：

// 列出iPhone上所有的字体 // List all fonts on iPhone

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];

如果使用iPhone SDK v2.1输出结果如下：

在选用非系统字体的时候，你需要确保选择的字体在列表中。在将来的iPhone OS中字体列表是否会改变还有待观察。建议重新运行下上述代码段进行确认。
