我用UIAppearance 来设置自己的导航工具栏,
[[UINavigationBar appearance] setTintColor:[UIColor blackColor]];
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"nav5.png"] forBarMetrics:UIBarMetricsDefault];
但一些关于我申请的意见并不需要。 我怎样才能摆脱它呢? 这样我只能用IB来表达相关的观点?
您不需要使用代理。 只要得到实际的导航栏, 它应该看起来不同, 并直接在它上设置颜色 。
[navigationBarInstance setTintColor:[UIColor blackColor]];
[navigationBarInstance setBackgroundImage:[UIImage imageNamed:@"nav5.png"] forBarMetrics:UIBarMetricsDefault];
您还可以将两个值设置为 nil , 您想要再次使用标准样式。 (由 Ben Clayton 测试)。
[navigationBarInstance setTintColor:nil];
[navigationBarInstance setBackgroundImage:nil forBarMetrics:UIBarMetricsDefault];
