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？向第三幅图片一样。。。




需要push的视图里面定义一个事件


- (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


- (void)viewDidLoad{ [super viewDidLoad]; UIButton *backBtn = [UIButton buttonWithType:UIButtonTypeCustom]; backBtn.frame = CGRectMake(0, 0, 44, 44); [backBtn setImage:[UIImage p_w_picpathNamed:@"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];}
