目标C：子视图不能点击

-1

我即将实施的iPhone应用程序类似于Facebook的侧边导航。我可以毫无问题地将其滑入和滑出，但是当我想单击某个按钮或该导航视图中的任何内容时，什么都不会发生。目标C：子视图不能点击

这里是我在viewDidLoad中初始化为我的侧导航视图的代码：

self.sideNavigationView = [[UIView alloc] initWithFrame:CGRectMake(self.navigationController.view.frame.size.width, 20, 238, self.navigationController.view.frame.size.height-20)]; 
[self.navigationController.view addSubview:self.sideNavigationView];

然后，我有下面的方法来将其滑动地：

- (IBAction) openMenuBar: (id) sender {  
if (!self.sideNavigationIsExpanded) { 
    self.sideNavigationView.frame = CGRectMake(self.navigationController.view.frame.size.width, 20, 238, self.navigationController.view.frame.size.height-20); 

} 
CGRect destination = self.navigationController.view.frame; 
CGRect sideNavigationDestination = self.sideNavigationView.frame; 

sideNavigationDestination.size.width = 238; 


// Slide back 
if (self.sideNavigationIsExpanded) {  
    sideNavigationDestination.origin.x = self.view.frame.size.width; 
    destination.origin.x = 0; 
    sideNavigationDestination.origin.y = 20; 
    self.sideNavigationIsExpanded = NO; 
} 
// Slide in 
else { 
    sideNavigationDestination.origin.x = self.view.frame.size.width; 
    destination.origin.x = - sideNavigationDestination.size.width;    

    sideNavigationDestination.origin.y = 20; 
    self.sideNavigationIsExpanded = YES; 

    self.sideNavigationView.hidden = NO; 
} 


[UIView animateWithDuration:0.25 animations:^{ 

    self.sideNavigationView.frame = sideNavigationDestination; 
    self.navigationController.view.frame = destination;   


} completion:^(BOOL finished) { 
    if (!self.sideNavigationIsExpanded) 
     self.sideNavigationView.hidden = YES; 
    self.view.userInteractionEnabled = !self.sideNavigationIsExpanded; 
    self.sideNavigationView.userInteractionEnabled = self.sideNavigationIsExpanded;   
}]; 

    }

我尝试的几种组合userInteractionEnabled =是在每个子视图...没有任何改变... 难道是我的sideNavigationView的子视图是不可选的，因为当我初始化它是不可见的？我试着用一个可见的框架初始化它（CGRectMake（0,0,238,300））并且工作。 -_- 那么我怎么能解决我的问题？

由于sideNavigationView是self.view的子视图那么这行：

self.view.userInteractionEnabled = !self.sideNavigationIsExpanded;

是防止接触从根本上达到你sideNavigationView。即使您已在下一行中将子视图的属性设置为YES，视图也不会将它的子视图传递给它自己的userInteractionEnabled属性。

至于初始化屏幕外，我不认为这会对一旦移回屏幕视图是否可以接收触摸任何影响。
