为UILabel设置一些不同的字体的问题

我想将字体大小和familyname设置为titleLabel。 // Helvetica Neue UltraLight

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

这不起作用。

请告诉我什么可能是错的？

任何帮助将不胜感激？

Answer 1

正确的fontName是@"HelveticaNeue-UltraLight" 。

使用这样的东西来获得一个很好的格式化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

您使用错误的字体名称，正确的一个将是：

 [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，有些字体可能不会出现在所有版本的iOS上，因为苹果公司逐渐添加（有时可能删除）标准操作系统集的字体。

在操作系统启动5.0版本中出现“HelveticaNeue-UltraLight”字体。 如果你想在较旧的操作系统版本中使用它，你需要把它embedded到你的应用程序中 – 例如检查这个答案 ，了解如何做到这一点

请参阅iOS中可用的字体列表，并根据此使用字体名称…
