后退按钮不会在导航栏中获得更改颜色

Question

抱歉英语不好:-(
在这里我使用xcode 5和ios7，当在pushviewcontroller之后获取时，可以在后退按钮中改变颜色。

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
        ListViewController *viewList = [[ListViewController alloc] initWithNibName:@“ListViewController” bundle:nil];
        [self.navigationController pushViewController: viewList animated:YES];
}

用户按下一个单元格，然后会出现ListViewController。在导航栏中，右侧栏按钮显示为粉红色。但后栏按钮没有变色。请看下面的屏幕截图。

我们可以在导航栏中更改颜色后退按钮吗？或者应该在后退按钮中添加图像？

Answer 1

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
        ListViewController *viewList = [[ListViewController alloc] initWithNibName:@“ListViewController” bundle:nil];
        self.navigationController.navigationBar.tintColor=[UIColor readcolor]; //set color as you want…..
        [self.navigationController pushViewController: viewList animated:YES];
}

试试吧......快乐的代码： - ）

Answer 2

要更改应用中的所有UIBarButtonItems颜色，请在AppDelegate的应用程序窗口中设置tintColor属性。比如，

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.tintColor = [UIColor blueColor]; // or set color as you want.
    return YES;
}

Answer 3

您无法更改backBarButtonItem的颜色，但可以更改其色调。尝试将以下内容添加到App Delegate： [[UIBarButtonItem appearance] setTintColour:pinkColour]

小心，这会使你的酒吧按钮的全部粉红色。

尝试使用自定义后退按钮

UIView *backBtnView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 70, 40)];
backBtnView.backgroundColor = [UIColor clearColor];
UIButton *backBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[backBtn setBackgroundColor:[UIColor clearColor]];
[backBtn setImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal];
[backBtn addTarget:self action:@selector(backBtnClicked) forControlEvents:UIControlEventTouchUpInside];
[backBtn setFrame:CGRectMake(5, 5, 57, 30)];
[backBtnView addSubview:backBtn];
self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc]initWithCustomView:backBtnView];
