ios7禁止默认划动返回

 self.navigationController.interactivePopGestureRecognizer.enabled = NO;

在使用之前先要判断是否ios7,不然会导致crash。然后创建一个自己的navigationController继承UINavigationController。之后还要设置UINavigationControllerDelegate,这样以上的方法才能触发。最后就判断要show出来的viewController是否需要支持划动返回了。

 

 

 

 - (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated

{
    if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)]) {
        if (viewController.class == [MyViewController class])
        {
            self.interactivePopGestureRecognizer.enabled = NO;
        } else {
            self.interactivePopGestureRecognizer.enabled = YES;
        }
    }
}
