如何更改默认backBarButtonItem上的颜色/图像？ [英] How do you change color/image on the default backBarButtonItem?

问题描述

我需要在默认的self.navigationItem.backBarButtonItem上更改颜色。为了实现这一点，我创建了一个自定义Button类并实现如下：

I need to change color on the default "self.navigationItem.backBarButtonItem". To accomplish this I´ve created an custom Button class and implemented it like this:

- (void)viewDidLoad {
[super viewDidLoad];    
BackButton *blueSaveButton = [[BackButton alloc] init];
UIBarButtonItem *temporaryBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:blueSaveButton];
temporaryBarButtonItem.title = @"Tillbaka";
self.navigationItem.backBarButtonItem = temporaryBarButtonItem;
[temporaryBarButtonItem release];
[blueSaveButton release];
[self gotoLocation];

}

但这没有效果完全按下按钮。
那你怎么设法做到这一点而不破坏导航栏的默认/继承行为？

But this has no effect at all on the button. So how do you manage to do this without "breaking" the default/inherited behavior of the navigationbar?

编辑：原因是按钮需要是公司品牌，所以默认样式不会。

The reason is that the button needs to be corporate branded, so default styles will not do.

这将覆盖导航栏的默认行为。

This will override the default behavior of navigationbar.

2：在需要自定义按钮的每个视图中实现此功能：
