iOS 上UINavigationController视图压栈形式,可以在当前视图无限制push许多视图,然而一些会觉得自带的push按钮不够美观,而且当上的上一个页面title很长的时候,那个返回按钮就很长,怎样定义一个自己返回按钮呢?像第三幅图片一样。。。
需要push的视图里面定义一个事件
[cpp] view plaincopy
- - (IBAction)pushVC:(id)sender {
- NavViewController *navVC = (NavViewController *)[self.storyboard instantiateViewControllerWithIdentifier:@"NavViewController"];
- navVC.title = NSLocalizedString(@"设置", nil);
- [self.navigationController pushViewController:navVC animated:YES];
- }
替换返回按钮,定义自定义按钮
[cpp] view plaincopy
- - (void)viewDidLoad
- {
- [super viewDidLoad];
- UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom];
- backBtn.frame = CGRectMake(0, 0, 44, 44);
- [backBtn setImage:[UIImage imageNamed:@"back.png"] forState:UIControlStateNormal];
- [backBtn addTarget:self action:@selector(doBack:) forControlEvents:UIControlEventTouchUpInside];
- UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithCustomView:backBtn];
- self.navigationItem.leftBarButtonItem = backItem;
- // Do any additional setup after loading the view.
- }
- -(void)doBack:(id)sender
- {
- [self.navigationController popViewControllerAnimated:YES];
- }
