在iOS 7中更改条形按钮的颜色 [英] Change the color of a bar button in iOS 7

问题描述

我在包含视图的viewDidLoad中有以下代码：

I have the following code in my viewDidLoad of my containing view:

// Now add the next button
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc] initWithTitle:@"Next" style:UIBarButtonItemStylePlain target:self action:@selector(self)];
self.navigationItem.rightBarButtonItem.tintColor = [UIColor blueColor];
self.navigationItem.rightBarButtonItem = nextButton;

UINavigationController父级在viewDidLoad中有这个：

The UINavigationController parent has this in viewDidLoad:

[super viewDidLoad];
// Do any additional setup after loading the view.

self.navigationBar.tintColor = [UIColor whiteColor];
self.navigationBar.barTintColor = [UIColor blackColor];

如何自定义rightBar按钮以更改背景颜色和文本颜色？

How do I just customize the rightBar button to change the background color and maybe the text color?

推荐答案

分配按钮后，必须在按钮上设置tintColor属性。

You have to set the tintColor property on the button after you assign the button.

self.navigationItem.rightBarButtonItem = nextButton;
self.navigationItem.rightBarButtonItem.tintColor = [UIColor blueColor];

而不是

self.navigationItem.rightBarButtonItem.tintColor = [UIColor blueColor];
self.navigationItem.rightBarButtonItem = nextButton;
