为 UILabel 设置一些不同字体的问题

Question

我想将字体大小和姓氏设置为 titleLabel。 //Helvetica Neue UltraLight

 [titleLabel setFont:[UIFont fontWithName:@"Helvetica Neue UltraLight" size:25.0f]];

这不起作用。

请告诉我可能出了什么问题？

任何帮助将不胜感激？

Answer 1

正确的字体名称是@"HelveticaNeue-UltraLight"。

使用类似这样的方法来获得格式良好的可用字体名称列表：

NSMutableString *str = [NSMutableString stringWithCapacity:1000];
for (NSString *familyName in [UIFont familyNames]) {
    [str appendFormat:@"%@\n", familyName];
    for (NSString *fontName in [UIFont fontNamesForFamilyName:familyName]) {
        [str appendFormat:@"    %@\n", fontName];
    }
    [str appendString:@"\n"];
}
NSLog(@"%@", str);

Answer 2

您使用了错误的字体名称，正确的是：

[titleLabel setFont:[UIFont fontWithName:@"HelveticaNeue-UltraLight" size:25.0f]]; 

您可以使用 UIFont 中的 +fontNamesForFamilyName: 方法查看给定字体系列的所有可用字体名称列表，例如：

[UIFont fontNamesForFamilyName:@"Helvetica Neue"]

编辑：另外请注意，随着 Apple 逐渐从标准操作系统集中添加（有时可能会删除）字体，某些字体可能不会出现在所有版本的 iOS 上。

从 5.0 版本开始，操作系统中似乎存在“HelveticaNeue-UltraLight”字体。如果您想在较旧的操作系统版本中使用它，您需要将其嵌入到您的应用程序中 - 查看例如 this answer 以了解如何执行此操作的详细信息

Answer 3

请看List of Fonts available in iOS 并根据此使用字体名称...
