iphone - 在 View IOS 中禁用用户交互

Question

我正在使用以下代码禁用和启用 View ....

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

如果我这样做，它的所有 subview 也会受到影响...所有都被禁用，我该如何只针对特定 View ？可能吗？

Answer 1

完全一样，假设您的其他 View 是成员，或者您可以遍历 self.view 的 subview 数组，如下所示:

MyViewController.h

UIView* otherView;

MyViewController.m

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

或者:

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.
}
