How to place UILabel in the center of navigation bar
提问by FrozenHeart
How to place UILabelin the center of navigation bar in XCode 6? Is it possible at all? I can place here, for example, UIButton, but unable to place UILabel. If no, what can I do then? Place a UIButtonwith the appropriate text and make it non-clickable?
如何UILabel在 XCode 6 中放置在导航栏的中心？有可能吗？例如，我可以在这里放置UIButton，但无法放置UILabel。如果没有，那我该怎么办？将 aUIButton与适当的文本一起放置并使其不可点击？
Thanks in advance.
提前致谢。

In Xcode 6if you want to put a label inside the UINavigationBarfirstly you have to put a UIView there then put the UILabel inside the UIView (this is from the Storyboard btw).
在Xcode 6如果你想要把一个标签内UINavigationBar首先你必须把一个UIView有然后把里面的UIView中的UILabel（这是从故事板BTW）。
If you do not put the UIViewfirst then the UILabelwill never get put onto the UINavigationBar.
如果您不放第UIView一个，UILabel则永远不会放上UINavigationBar.

Create a UIView and add UILabelas it's subview and then set your NavigationItem's titleView as previously created UIView.
创建一个 UIView 并添加UILabel为它的子视图，然后将您NavigationItem的 titleView设置为之前创建的 UIView。
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 150, 40)];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 150, 40)];
label.text = @"Hello";
label.textAlignment = NSTextAlignmentCenter;
[view addSubview:label];
self.navigationItem.titleView = view;
Note: Don't forget to set your own frame values to get better result.
注意：不要忘记设置您自己的帧值以获得更好的结果。

Just make sure you try viewWillLayoutSubviewsmethod instead of viewDidLoadthat was what worked for me. Cheers!
只要确保您尝试viewWillLayoutSubviews方法而不是viewDidLoad对我有用的方法。干杯!
