使用自定义图像和文本颜色更改后退按钮 [英] change backbutton with custom image and textcolor

问题描述

我想在导航栏中更改后退按钮的外观.为此，我有这段代码.

I want to change the backbutton appearance for my backbutton in my navigation bar. For that I have this piece of code.

UIImage *backButtonImage = [UIImage imageNamed:@"backbutton.png"];
UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
backbutton.backgroundColor = [UIColor colorWithPatternImage:backButtonImage];
backbutton.titleLabel.text = @"back";
backbutton.titleLabel.textColor= [UIColor colorWithRed:50/255.0
                                                 green:158/255.0
                                                  blue:218/255.0
                                                 alpha:1.0];

backbutton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
UIBarButtonItem * back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
[backbutton addTarget:self action:@selector(back_Clicked) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = back;

但是我仍然得到标准的后退按钮.有帮助吗?

But still I get the standard back button. Any help ?

推荐答案

使用以下代码满足您的要求..

using bellow code for your requirement..

- (void)viewDidLoad
{
        ///write your code

        UIImage *backButtonImage = [UIImage imageNamed:@"backbutton.png"];
        UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
        //[backbutton setImage:backButtonImage forState:UIControlStateNormal];//this line for set only image on button
        [backbutton setBackgroundImage:backButtonImage forState:UIControlStateNormal];
        [backbutton setTitle:@"Back" forState:UIControlStateNormal];
        backbutton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
        UIBarButtonItem * back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
        [backbutton addTarget:self action:@selector(back_Clicked) forControlEvents:UIControlEventTouchUpInside];
        self.navigationItem.leftBarButtonItem = back;
}

当后退按钮单击下面的方法调用时，您将转到上一个Viewcontroller

when back button clicked bellow method call and you will go to previous viewcontroller

-(void)back_Clicked{
      [self.navigationController popViewControllerAnimated:YES];
}
