When on of them is tapped I want to remove all the recognizers of the others.

I知道ManagedObjects有 [Entity allObjects];

I know ManagedObjects has [Entity allObjects];

如何创建all objects类方法？

How can I create my "all objects" class method ?

推荐答案

我有两个想法：

1 /创建一个类数组所有实例静态NSArray *实例; ，在初始化时注册它们，在解除分配时注销。该数组应该只有弱引用，否则永远不会被释放。

1/ Create a class array with all the instances static NSArray* instances;, register them when initializing, unregister when deallocating. The array should have only weak references, otherwise they will never be deallocated.

2 / NSNotification。所有实例都可以等待通知，如果您点按，则会发送通知。

2/ NSNotification. All instances can wait for a notification and if you tap, you send the notification.
