ios側(cè)滑的封裝 ?來點兒實際的 直接擼代碼 簡單搞定
a,實現(xiàn)方法 viewdidload中
- (void)viewDidLoad {
[super viewDidLoad];
self.delegate = self;
__weak typeof(self) weakSelf = self;
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.interactivePopGestureRecognizer.delegate = weakSelf;
}
}
b,實現(xiàn)UIGestureRecognizerDelegate中的方法
-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer{
if (self.navigationController.viewControllers.count == 1) {
return NO;
}else{
return YES;
}
}
c 實現(xiàn)UINavigationControllerDelegate 的方法
- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
if ([navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
navigationController.interactivePopGestureRecognizer.enabled = YES;
}
//使navigationcontroller中第一個控制器不響應右滑pop手勢
if (navigationController.viewControllers.count == 1) {
navigationController.interactivePopGestureRecognizer.enabled = NO;
navigationController.interactivePopGestureRecognizer.delegate = nil;
}
}
-(void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated{
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
}
[self.navigationController pushViewController:viewController animated:animated];
}
