禁用视图IOS中的用户交互

Question

我正在使用以下代码禁用和启用视图...

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

如果我这样做，所有的子视图也会受到影响……全部禁用，如何仅针对特定视图执行操作？有可能吗？

Answer 1

完全相同，假设您的另一个视图是成员，或者您可以遍历self.view的子视图数组，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.
}

Answer 2

在swift UIView中，确实有userInteractionEnabled属性来使其响应或不响应。要使full View无响应，请使用代码：

// make screen unresponsive
self.view.userInteractionEnabled = false
//make navigation bar unresponsive
self.navigationController!.view.userInteractionEnabled = false

// make screen responsive
self.view.userInteractionEnabled = true
//make navigation bar responsive
self.navigationController!.view.userInteractionEnabled = true

Answer 3

for (UIView* view in self.view.subviews) {

    if ([view isKindOfClass:[/*"which ever class u want eg UITextField "*/ class]])

        [view setUserInteractionEnabled:NO];

}

希望能有所帮助。快乐编码:)
