UIBarButtonItem, set exclusive touch
提问by Mike Mellor
Is there a way to make UIBarButtonItemexclusive touch? At the moment you can select multiple at the same time and it keeps crashing my application.
有没有办法进行UIBarButtonItem独家触摸？目前，您可以同时选择多个，但它不断使我的应用程序崩溃。

Slightly easier method than subclassing the navbar but the same idea;
比继承导航栏更简单的方法，但思路相同；
for(UIView *temp in self.navigationController.navigationBar.subviews)
{
[temp setExclusiveTouch:YES];
}
Put this just after you add your bar button items.
在添加条形按钮项目之后放置它。

I managed this problem by subclassing UINavigationBar and overriding layoutSubviews method. Something like this:
我通过继承 UINavigationBar 和覆盖 layoutSubviews 方法来解决这个问题。像这样的东西：
- (void)layoutSubviews {
[super layoutSubviews];
for (UIView *view in self.subviews) {
view.exclusiveTouch = YES;
}
}

Dredging up the past I apologise. I stumbled into this and hoped there was a better way than looping through subviews.
疏浚过去我道歉。我偶然发现了这一点，并希望有一种比循环子视图更好的方法。
I found that the following makes the UIBarButtonItems exclusive:
我发现以下使 UIBarButtonItems 独占：
[self.navigationController.navigationBar setExclusiveTouch:YES];
iOS7 may have made exclusive touch inherited.
iOS7 可能已经继承了独家触摸。

In iOS 7 it wasn't working. I have used this method to try fix it.
在 iOS 7 中它不起作用。我已经使用这种方法尝试修复它。
for(UIView *temp in self.navigationController.navigationBar.subviews){
[temp setExclusiveTouch:YES];
for(UIView *temp2 in temp.subviews){
[temp2 setExclusiveTouch:YES];
}
}

This does not work for UIBarButtonItem created using initWithTitle
这不适用于使用 initWithTitle 创建的 UIBarButtonItem
