Question

我正在尝试使用外观代理设置自定义字体。

[[UILabel appearance] setTitleTextAttributes:@{
    UITextAttributeFont:[UIFont fontWithName:@"PT Sans Narrow" size:10.0]
}];

我已将ttf添加到我的项目中，并确认字体名称是正确的。

XCode给了我这个错误：

2012-11-27 02:04:00.002 dashboard-mock[17093:11303] -[_UIAppearance setTitleTextAttributes:]: unrecognized selector sent to instance 0x712a1c0

libc++abi.dylib: terminate called throwing an exception

我做错了什么？

Answer 1

-setTitleTextAttributes功能

时，您正在使用UINavigationBar标签

if([[UINavigationBar appearance] respondsToSelector:@selector(setTitleTextAttributes:)])
   [[UINavigationBar appearance] setTitleTextAttributes:@{
                         UITextAttributeFont:[UIFont systemFontOfSize:12],
                    UITextAttributeTextColor:[UIColor redColor]
}];

感谢

Answer 2

想出来，它是setFont而不是setTitleTextAttributes

[[UILabel appearance] setFont:[UIFont fontWithName:@"PT Sans Narrow" size:10.0]];

修复错误设置自定义ios字体
