ios - 从导航堆栈中删除 ViewController
<p><p>我用代码来做:</p>
<pre><code>NSArray *viewControllersFromStack = ;
NSMutableArray *viewControllersFromStackMutable = ;
NSMutableArray *viewControllersToRemove = [init];
for (UIViewController *currentVC in viewControllersFromStack)
{
if (])
{
;
if (viewControllersToRemove.count == 2)
{
UIViewController *oneVCtoRemove = ;
;
;
}
}
}
</code></pre>
<p>问题是我在导航项中引用了已删除的 VC。如何解决？</p></p>

<p><p>当您想从导航堆栈中删除 View 时，您只需在导航栏上调用此方法即可将 View 从堆栈中弹出:</p>
<pre><code>;
</code></pre>
<p>要弹出外部 View ，请使用</p>
<pre><code>for(UIViewController *currentVC in viewControllersFromStack)
{
if(])
{
;
}
}
</code></pre></p>
