Question

I’m new to XCode/iOS and I’m trying to figure out how to move a Label based on the left (or right) side, not the center.

All I can find is something like this:

[myLabel setCenter:CGPointMake(x,y)];

I’ve also seen this variant:

myLabel.center=CGPointMake(x,y);

My question has two parts:

1. How do do something similar, but without using the label center?

2. Is “.center” a property of the UILabel object? For example, in MS/VB/C#/etc. objects have “.left, .right, .top, .bottom” for positioning – is there something similar in iOS/Objective-C?

Answer 1

center is a property of UIView, and no, there’s no equivalent left, right, or whatever. You need to do the calculation manually: the label’s left side is label.frame.origin.x and its right side is label.frame.origin.x + label.frame.size.width. If you want to move the label so it’s right-aligned with a particular coordinate, then you can do something like this:

label.frame = CGRectMake(100 - label.frame.size.width, label.frame.origin.y, label.frame.size.width, label.frame.size.height);
