Why not to use setBarTintColorfor appearance proxy, you can do this:
为什么不setBarTintColor用于外观代理，您可以这样做：
if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1)
{
[[UINavigationBar appearance] setTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];
}
else
{
[[UINavigationBar appearance] setBarTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];

Using respondsToSelector for version checking may be better.
使用 RespondsToSelector 进行版本检查可能会更好。
if ([self.navigationBar respondsToSelector:@selector(setBarTintColor:)]) {
[self.navigationBar setBarTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];
} else {
[self.navigationBar setTintColor: [UIColor colorWithRed:129/255.0 green:200/255.0 blue:244/255.0 alpha:1.0]];
}

In Swift, for me, I wanted to change tint color for the Cancel and Send buttons, when the e-mail pops up. And it worked great.
在 Swift 中，对我来说，当电子邮件弹出时，我想更改取消和发送按钮的色调颜色。而且效果很好。
(UIBarButtonItem.appearanceWhenContainedInInstancesOfClasses([UINavigationBar.self])).tintColor = UIColor.whiteColor()
