ios - Outlet collections, i want to access the properties(hidden) for my UIimageview

Question

I can only access the id of my outlet collection and an id does not have a hidden property

This is my outlet collection

@property (strong, nonatomic) IBOutletCollection(UIImageView) NSArray *hearts;

and this is when I try to call it, and change it to hidden.

[self.hearts objectAtIndex:0].hidden =YES;

I can not because objectAtIndex only returns an id

Thanks for any help

您可以尝试枚举集合中的对象，使用您期望的类型（例如，for (UIView *heartView in self.hearts)）或首先强制转换 objectAtIndex:0，然后设置隐藏属性。
