在IOS中自定义后退按钮

如何使用barmetrics在iOS中创建没有文本的自定义后退按钮

我想做点像

你可以将其放在你的应用程序委托中，它会将背景图像设置为应用程序中的所有后退按钮（当然，对于控制状态和条形图指标）

编辑： 如果您想更改某些内容，请使用以下代码：

- (void)setBackButton
{
    UIButton *backButton =  [UIButton buttonWithType:UIButtonTypeCustom];
    [backButton setImage:[UIImage imageNamed:@"BackButton.png"] forState:UIControlStateNormal];
    [backButton addTarget:self action:@selector(backButtonTapped:) forControlEvents:UIControlEventTouchUpInside];[button setFrame:CGRectMake(0, 0, 32, 32)];

    self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithCustomView:backButton] autorelease];
}

- (void)backButtonTapped:(id)sender
{
    [self.navigationController popViewControllerAnimated:YES];
}  

---

像这样的怎么样

UIButton *backButton = [[UIButton alloc] initWithFrame:CGRectMake(YourFrame)];

[backButton setTitle:@"<" forState:UIControlStateNormal];

[backButton addTarget:self action:@selector(callSelectorMethod) forControlEvents:UIControlEventTouchUpInside];

self.navigationItem.rightBarButtonItem  = [[[UIBarButtonItem alloc] initWithCustomView:backButton] autorelease];

[backButton release],backButton=nil;

UIButton*backButton=[[UIButton alloc]initWithFrame:CGRectMake（YourFrame）]；
[backButton setTitle:@“以下是解决方案：

 UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
    [button setImage:[UIImage imageNamed:@"BackButton.png"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(popBack) forControlEvents:UIControlEventTouchUpInside];
    [button setFrame:CGRectMake(0, 0, 32, 32)];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];

多亏了
你试过了吗？我试过了。图像即将出现，但它采用了后退按钮的全尺寸，而不是图像尺寸。“后退”也将显示：（你可以使用第二种方法，为此，你可以在谷歌上找到很多解决方案。点击此链接此解决方案不是100%好，因为它删除了uinavigationcontroller的滑动转换。这是一个经常被问到的问题！检查：
 UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
    [button setImage:[UIImage imageNamed:@"BackButton.png"] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(popBack) forControlEvents:UIControlEventTouchUpInside];
    [button setFrame:CGRectMake(0, 0, 32, 32)];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
