自定义导航栏按钮
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view.
UIButton * leftBtn = [UIButton buttonWithType:UIButtonTypeSystem];leftBtn.frame = CGRectMake(0, 0, 25,25);
[leftBtn setBackgroundImage:[UIImage imageNamed:@"nav_back"] forState:UIControlStateNormal];
[leftBtn addTarget:self action:@selector(leftBarBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:leftBtn];
}
- (void)leftBarBtnClicked:(UIButton *)btn{
[self.navigationController popViewControllerAnimated:YES];
}
调整导航栏按钮位置
//创建返回按钮
UIButton * leftBtn = [UIButton buttonWithType:UIButtonTypeSystem];
leftBtn.frame = CGRectMake(0, 0, 25,25);
[leftBtn setBackgroundImage:[UIImage imageNamed:@"icon_back"] forState:UIControlStateNormal];[leftBtn addTarget:self action:@selector(leftBarBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem * leftBarBtn = [[UIBarButtonItem alloc]initWithCustomView:leftBtn];
//创建UIBarButtonSystemItemFixedSpace
UIBarButtonItem * spaceItem = [[UIBarButtonItem alloc]initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
//将宽度设为负值
spaceItem.width = -15;
//将两个BarButtonItem都返回给NavigationItem
self.navigationItem.leftBarButtonItems = @[spaceItem,leftBarBtn];
自定义返回按钮后滑动返回手势失效
<UIGestureRecognizerDelegate>
self.navigationController.interactivePopGestureRecognizer.delegate = self;
全屏滑动返回手势
<UIGestureRecognizerDelegate>
- (void)viewDidLoad{
[super viewDidLoad];
// 获取系统自带滑动手势的target对象
id target = self.interactivePopGestureRecognizer.delegate;
// 创建全屏滑动手势，调用系统自带滑动手势的target的action方法
// handleNavigationTransition系统滑动方法 不会因为私有API被拒
UIPanGestureRecognizer *pan = [[UIPanGestureRecognizer alloc] initWithTarget:target action:@selector(handleNavigationTransition:)];
// 设置手势代理，拦截手势触发
pan.delegate = self;
// 给导航控制器的view添加全屏滑动手势
[self.view addGestureRecognizer:pan];
// 禁止使用系统自带的滑动手势
self.interactivePopGestureRecognizer.enabled = NO;
}
