How to hide a bunch of labels in an IBOutletCollection?

Question

New to Objective-C and iOS development, would love a hand here!

I have written up some code such that

IBOutletCollection(UILabel) NSArray *allLabels;

In IB I have linked up all my labels in my view to this collection, where I want to hide them for a certain condition. However, I am not sure how to do so. Obviously to hide a single label I'd use

labelX.hidden = YES;

however it is not ideal for me to do this without a collection, as I have many labels to hide.

Thanks for your tips in advance!

Answer 1

try this...

[allLabels setValue:@(YES) forKey:@"hidden"];

Answer 2

Just enumerate collection and do whatever you want with contents:

[allLabels enumerateIndexesUsingBlock:^(UILabel *label, NSUInteger idx, BOOL *stop) {
    label.hidden = YES;
}];

Answer 3

Swift Version for Array type:

(allLabels as NSArray).setValue(NSNumber(bool: true), forKey: "hidden")
