How to construct IBOutlet names in code in order to change them?

Question

Let's say I've got several UILabels which have been set up in IB and connected to IBOulets in code (label1, label2, label3, label4)

How would I create these variable names within code, so that I could change the text of each one in a loop, where the labels are taken from a NSArray.

Here's the pseudo-code:

labelArray = [NSArray arrayWithObjects:@"this", @"array", @"has", @"a", @"random", @"amount", @"of", @"items", nil];
for (int i = 0; i < [labelArray count]; i++) 
{
    // labelx is the constructed name of the IBOutlet
    lablex.text = [labelArray objectAtIndex:i];

}

How do I construct 'labelx' above? Could this be done using Blocks?

Answer 1

You would have to initialize the array at some place, using

labelArray = [NSArray arrayWithObjects:@"this", @"array", @"has", nil];
uiLabelArray = [NSArray arrayWithObjects:label1,label2,label3,nil];

then

for (int i = 0; i < [uiLabelArray count]; i++) 
{
    [uiLabelArray objectAtIndex:i].text = [labelArray objectAtIndex:i];
}

Answer 2

You can use key value coding (KVC). It would look something like:

[[self valueForKey:[NSString stringWithFormat:@"label%d", i]] setText:[labelArray objectAtIndex:i]];
