iOS 7中UINavigation Back Button的自定义图像 [英] Custom image for UINavigation Back Button in iOS 7

问题描述

我有一个自定义 UIBarButtonItem ，其图像在iOS 6.1中运行良好。但iOS 7有一个 tintColor ，它将这种颜色覆盖在我的图像上。如果我将 tintColor 设置为 [UIColor clearColor] ，该按钮不会全部显示在一起。

I have a custom UIBarButtonItem with an image that works fine in iOS 6.1. But iOS 7 has a tintColor and it overlays this color over my image. If I set the tintColor to [UIColor clearColor] the button doesn't show up all together.

如何在iOS 7中显示我的后退按钮，就像在iOS 6中一样？请帮帮忙？

How can I have my back button show up in iOS 7 as it does in iOS 6? Please help?

推荐答案

尝试在ios7中设置 UIBarButtonItem ，如下所示： -

Try to set UIBarButtonItem like this way in ios7:-

UIImage *temp = [[UIImage imageNamed:@"theImage"] imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal];    
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithImage:temp style:UIBarButtonItemStyleBordered target:self action:@selector(action)];

为支持iOS7版本以及更低版本，请检查 system-version 并设置如下代码： -

For supporting both version iOS7 as well as lower then you check system-version and set code like:-

UIImage *temp=nil;

if([[[UIDevice currentDevice] systemVersion] floatValue] < 7.0)
{ 
    temp = [UIImage imageNamed:@"btn-back.png"]; 
}
else
{ 
    temp = [[UIImage imageNamed:@"btn-back.png"] imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal];
 }
