UIView Frame Helpers

Drowning in layout and positioning code? Slim down by up to 75% in common cases.

Setting X and Y

// Then
CGRect frame = myView.frame;
frame.origin.x = ...
frame.origin.y = ...
myView.frame = frame;

// Now
[myView setX:myXVal andY:myYVal];

Adjusting X and Y

// Then
CGRect frame = myView.frame;
frame.origin.x = frame.origin.x + xDelta;
frame.origin.y = frame.origin.y + yDelta;
myView.frame = frame;

// Now
[myView adjustX:xDelta andY:yDelta];

Positioning relative to another view, or the superview

// Then
CGRect frame = myView.frame;
frame.origin.x = myOtherView.origin.x + myOtherView.size.width + kMyPaddingConst;
frame.origin.y = myOtherView.origin.y;
myView.frame = frame;

// Now
[myView insideTopEdgeOfSuperviewBy:0];
[myView outsideRightEdgeOf:myOtherView by:kMyPaddingConst];

Chaining

[[myView insideTopEdgeOfSuperviewBy:0] outsideRightEdgeOf:myOtherView by:kMyPaddingConst];
