• 禁止側滑初步實現

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

- (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，一般App在push操作時候會隱藏tabbar，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，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，保證push的控制器都在同一個navigationController的viewControllers中，這樣push、pop操作才生效。

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，通過preNavC來添加返回按鈕進行pop后退。

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滑了

• 禁止側滑終結版

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

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