Question

我有一个按钮（Buy）在另一个UIView（viewMenu）之上打开一个UIView（viewInAppPurchases）。 “购买”按钮位于UIView viewMenu中。我在UIView viewInAppPurchases中也有一个按钮（关闭）。

在单击viewInAppPurchases中的关闭按钮的代码中，它将关闭视图并返回viewMenu。但是当再次点击“购买”按钮时，没有任何反应。它应该重新打开viewInAppPurchases UIView。

我还应该添加和/或更改代码，以便再次单击“购买”按钮时，它将再次打开viewInAppPurchases？

在页眉文件中：

@property (strong, nonatomic) IBOutlet UIView *viewInAppPurchases;

在实现.m文件中：

- (IBAction)buttonClose: (UIButton*)sender
{
[_viewInAppPurchases removeFromSuperview];
}

以下是作为GaryRiches请求的IAP。我注意到我没有一个＆＃34;关闭按钮＆＃34; IAP本身的指令，但只能通过MenuViewController。

如何将关闭按钮说明放入其中？

Answer 1

我还应该在购买时添加和/或更改代码再次单击按钮，它将打开viewInAppPurchases 再次？

您应该将其添加回删除它的视图。

您可以通过以下方式在点击事件中执行此操作：

[self.view addSubview: _viewInAppPurchases];

另外，您是否考虑过隐藏它而不是完全删除它然后再添加它？

隐藏您的观点：

[_viewInAppPurchases setHidden:YES];

再次展示：

[_viewInAppPurchases setHidden:NO];

Answer 2

我改变了

removeFromSuperview

到

setHidden:Yes

它就行了。

removeFromSuperview无法重新打开
