禁止用户在视图IOS中交互 [英] Disable user interact in a view IOS

问题描述

我使用以下代码禁用和启用视图。

I am disabling and enabling a view using the following code....

[self.view setUserInteractionEnabled:NO];
[self.view setUserInteractionEnabled:YES];

如果我这样做，所有的subview也受到影响...所有都禁用，我只做特定的观点？是否可能？

If I do like this, all it subviews also got affected... All are disabled, how do I do only for particular view? Is it possible?

推荐答案

这是完全一样的，假设你的另一个视图是一个成员或者你可以迭代通过 self.view 的子视图数组，如下所示：

It's exactly the same, assuming your other view is either a member or you can iterate through self.view's array of subviews, like so:

MyViewController.h >

MyViewController.h

UIView* otherView;

MyViewController.m

otherView.userInteractionEnabled = NO; // or YES, as you desire.

或：

for (int i = 0; i < [[self.view subviews] count]; i++)
{
    UIView* view = [[self.view subviews] objectAtIndex: i];

    // now either check the tag property of view or however else you know
    // it's the one you want, and then change the userInteractionEnabled property.
}
