当我从导航栏中按下返回按钮时,我尝试跳过一个ViewController
。
当我转到下一个VC时,需要这样做:
A -> B -> C
但是,当我想从C返回时,我希望显示A
ViewController
:C -> A
我设法用下一个代码做到这一点:
NSMutableArray *newControllers = [[NSMutableArray alloc]initWithArray:controllers];
[newControllers removeObjectAtIndex:newControllers.count-2];
self.navigationController.viewControllers = newControllers;
问题是显示的导航栏。当我从A
ViewController
获取View时,将显示B ViewController的导航栏。有什么方法可以删除导航栏项,例如从层次结构中删除视图控制器?
最佳答案
UIViewController *vcPop = nil;
for (UIViewController *viewContrl in self.navigationController.viewControllers) {
if ([viewContrl class] == [YOUR POP VIEW CONTROLLER class]) {
vcPop = (YOUR POP VIEW CONTROLLER *)viewContrl;
break;
}
}
if(vcPop)
[self.navigationController popToViewController:vcPop animated:YES];
