Question

我正在尝试将图标（并保留标题）添加到导航控制器的后退按钮。看来如果我设置了UIBarButtonItem的图像，它会隐藏标题，所以我想我会尝试自定义视图。我试过了

UIButton* customButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[customButton setImage:[UIImage imageNamed:@"icon"] forState:UIControlStateNormal];
[customButton setTitle:@"Title" forState:UIControlStateNormal];
[customButton setAdjustsImageWhenHighlighted:YES];
[customButton setFrame:CGRectMake(0, 0, 125, 32)];

UIBarButtonItem* backButton = [[UIBarButtonItem alloc] initWithCustomView:customButton];
self.navigationItem.backBarButtonItem = backButton;

但是Apple文档说backBarButtonItem会忽略自定义视图，所以这不起作用。

我也试过这个：

self.navigationItem.leftBarButtonItem = backButton;
self.navigationItem.hidesBackButton = YES;

但是leftBarButtonItem太快显示一个屏幕，而hidesBackButton似乎没有隐藏backBarButtonItem。

还有另一种方法可以将图像和标题同时放到导航backBarButtonItem上吗？

Answer 1

首先使用代码UINavigationController

隐藏self.navigationItem.hidesBackButton = YES;提供的后退按钮

使用以下代码设置带图像和标题的自己的按钮

UIButton* customButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[customButton setImage:[UIImage imageNamed:@"icon"] forState:UIControlStateNormal];
[customButton setTitle:@"Title" forState:UIControlStateNormal];
[customButton setAdjustsImageWhenHighlighted:YES];
[customButton setFrame:CGRectMake(0, 0, 125, 32)];

UIBarButtonItem* backButton = [[UIBarButtonItem alloc] initWithCustomView:customButton];
self.navigationItem.backBarButtonItem = backButton;

将图像和标题添加到导航backBarButtonItem
