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

问题描述

我有一个自定义的 UIBarButtonItem，其图像在 iOS 6.1 中运行良好.但是 iOS 7 有一个 tintColor 并且它在我的图像上覆盖了这个颜色.如果我将 tintColor 设置为 [UIColor clearColor] 按钮不会一起显示.

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.

如何让我的后退按钮像在 iOS 6 中一样在 iOS 7 中显示?请帮忙?

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 中这样设置 UIBarButtonItem:-

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)];

要同时支持 iOS7 和更低版本，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];
 }
