Question

I am an iOS newbie, so please bear with me. I have a blank page with a button centered in it. I want to add another button to the view, just below the centered button. How would I do that? I have added the first button like this –

float x=60, y=200, dy=50;
CGRect frame = CGRectMake(x, y, 200, dy);
UIButton *inboxButton = [[[UIButton alloc] initWithFrame:frame]autorelease];
inboxButton.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
inboxButton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;

....

[theView addSubview:inboxButton];

Answer 1

Just calculate the second frame based on the first

CGRect secondFrame = CGRectMake(CGRectGetMinX(frame),
    CGRectGetMaxY(frame) + 8.0, // some y padding
    CGRectGetWidth(frame),
    CGRectGetHeight(frame));
