Get UILabel from UIView

I have added a number of labels to a view giving them tags.

What is the correct way to retrieve a label from the view. I am wanting to re-postion the label. Here is what I am using to retrieve the label and re-position it:

UILabel *theLabel = (UILabel *)[self.view viewWithTag:5];
[theLabel.layer setPosition:CGPointMake(100, 200)];

Is this the correct way of doing it?

You can use fast enumeration with a for-loop:

for (UIView *view in [self.view subViews]) {
     if([view isKindOfClass:[UILabel class]]) {
          // do your stuff here
     }
}

Try this, it will surely work.

To retrieve the label, use an IBOutlet if you've created it in Interface Builder, or a raw property or ivar if created in code. There's no need to loop the subviews or use viewWithTag if you've got a direct reference (outlet, property, ivar) to it.

To move the label, directly set its frame or center property without needing to access its layer.

There's no need to go to the layer level, although it might work fine.

theLabel.center = CGPointMake(100,200);

I guess that does the same thing, without looking at the documentation to verify that a layer's default anchor point is its center.
