• 禁止側(cè)滑初步實現(xiàn)

以前寫過博客導航控制器全屏滑動返回效果
但是現(xiàn)在我的項目都是使用第三方RTRootNavigationController來實現(xiàn)导饲，但是使用RTRootNavigationController如何禁止側(cè)滑呢？

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated {
    if ([NSStringFromClass([viewController class]) isEqualToString:@"SCOrderDetailVC"]) {
        viewController.fd_interactivePopMaxAllowedInitialDistanceToLeftEdge = 0;
        self.fd_fullscreenPopGestureRecognizer.enabled = NO;
    } else {
        viewController.fd_interactivePopMaxAllowedInitialDistanceToLeftEdge = GQ_WindowW;
        self.fd_fullscreenPopGestureRecognizer.enabled = YES;
    }
    [super pushViewController:viewController animated:animated];
}
- (UIViewController *)popViewControllerAnimated:(BOOL)animated {
    UIViewController *viewController = [super popViewControllerAnimated:animated];
    if ([NSStringFromClass([viewController class]) isEqualToString:@"SCOrderDetailVC"]) {
        viewController.fd_interactivePopMaxAllowedInitialDistanceToLeftEdge = 0;
        self.fd_fullscreenPopGestureRecognizer.enabled = NO;
    } else {
        viewController.fd_interactivePopMaxAllowedInitialDistanceToLeftEdge = GQ_WindowW;
        self.fd_fullscreenPopGestureRecognizer.enabled = YES;
    }
    return viewController;
}

但是問題來了氯材，一般App在push操作時候會隱藏tabbar渣锦，但是如果push過去之后換一個新的tabbar，那么push過去的控制器應該是繼承UITabBarController的子類氢哮，假如命名SCCrowdFundingTabBarController

• push換tabbar

SCCrowdFundingTabBarController.h

@interface SCCrowdFundingTabBarController : UITabBarController
@property (nonatomic, strong) SCNavigationController *preNavC;
@end

SCCrowdFundingTabBarController.m

#import "SCCrowdFundingTabBarController.h"
#import "SCCrowdFundingVC.h"
#import "SCTimeMarketSegmentVC.h"
@interface SCCrowdFundingTabBarController ()
@property (nonatomic, strong) SCNavigationController *crowdFundingNavi;
@property (nonatomic, strong) SCCrowdFundingVC *crowdFundingVC;

@property (nonatomic, strong) SCNavigationController *timeMarketNavi;
@property (nonatomic, strong) SCTimeMarketSegmentVC *timeMarketVC;
@end

@implementation SCCrowdFundingTabBarController

- (void)viewDidLoad {
    [super viewDidLoad];
    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:kLightGrayColor, NSForegroundColorAttributeName, nil] forState:UIControlStateNormal];
    [[UITabBarItem appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:kDeepBlueColor,NSForegroundColorAttributeName, nil]forState:UIControlStateSelected];

    self.viewControllers = @[self.crowdFundingNavi,self.timeMarketNavi, self.crowdFundingMeNavi];
}
- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    self.navigationController.navigationBar.hidden = YES;
}
- (void)viewDidDisappear:(BOOL)animated {
    [super viewDidDisappear:animated];
    self.navigationController.navigationBar.hidden = NO;
}
- (void)setPreNavC:(SCNavigationController *)preNavC {
    _preNavC = preNavC;
    self.crowdFundingVC.preNavC = self.preNavC;
    self.timeMarketVC.preNavC = self.preNavC;
}
- (SCNavigationController *)crowdFundingNavi {
    if (_crowdFundingNavi == nil) {
        SCCrowdFundingVC *vc = [[SCCrowdFundingVC alloc]init];
        self.crowdFundingVC = vc;
        _crowdFundingNavi = [[SCNavigationController alloc] initWithRootViewController:vc];
        [self setTabbar:@"眾籌" image:@"眾籌" seleImage:@"眾籌_選中" nav:_crowdFundingNavi];
    }
    return _crowdFundingNavi;
}
- (SCNavigationController *)timeMarketNavi {
    if (_timeMarketNavi == nil) {
        SCTimeMarketSegmentVC *vc = [[SCTimeMarketSegmentVC alloc]init];
        self.timeMarketVC= vc;
        _timeMarketNavi = [[SCNavigationController alloc] initWithRootViewController:vc];
        [self setTabbar:@"市場" image:@"時間市場" seleImage:@"時間市場_點擊" nav:_timeMarketNavi];
    }
    return _timeMarketNavi;
}

- (void)setTabbar:(NSString *)title image:(NSString *)image seleImage:(NSString *)seleImage nav:(SCNavigationController *)vc{
    vc.tabBarItem.title = title;
    vc.tabBarItem.image = [[UIImage imageNamed:image] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
    vc.tabBarItem.selectedImage = [[UIImage imageNamed:seleImage] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}
@end

push時候通過定義preNavC傳遞之前的NavigationController袋毙，保證push的控制器都在同一個navigationController的viewControllers中，這樣push冗尤、pop操作才生效听盖。

SCCrowdFundingTabBarController *vc = [SCCrowdFundingTabBarController new];
vc.preNavC = (SCNavigationController *)self.navigationController;
[self.navigationController pushViewController:vc animated:YES];

另外，SCCrowdFundingTabBarController里的控制器例如SCCrowdFundingVC也需要接收一個preNavC裂七，通過preNavC來添加返回按鈕進行pop后退皆看。

SCCrowdFundingVC.h

@interface SCCrowdFundingVC : GQSegmentViewController
@property (nonatomic, strong) SCNavigationController *preNavC;
@end

SCCrowdFundingVC.m

@implementation SCCrowdFundingVC

- (void)viewDidLoad {
    [super viewDidLoad];
     UIButton *backButton = [UIButton gq_buttonWithBackButton:@"返回" target:self action:@selector(backButtonClick)];
    self.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc]initWithCustomView:backButton];
}
- (void)backButtonClick {
    [self.preNavC popViewControllerAnimated:YES];
}
@end

但是進入SCCrowdFundingTabBarController之后的控制器通過上面的方法就沒法控制側(cè)滑了

• 禁止側(cè)滑終結版

了解導航控制器全屏滑動返回效果知道側(cè)滑的原理之后可以用如下方法進行控制了，萬能的方法背零。
在需要禁止的控制器添加代理<UIGestureRecognizerDelegate>腰吟，并添加如下代碼

- (void)viewDidLoad {
    [super viewDidLoad];
    // 禁止側(cè)滑
    id traget = self.navigationController.interactivePopGestureRecognizer.delegate;
    UIPanGestureRecognizer * pan = [[UIPanGestureRecognizer alloc]initWithTarget:traget action:nil];
    [self.view addGestureRecognizer:pan];
}
