Simple but powerful and useful Objective-C method that moves around a UIView.
I always use it because of no-rewriting of the same code again and again and again.
/** Moves a UIView origin to a new point taking into accout an offset from origin.
It's especially useful for dragging a View while binding it under a finger.
Please note that the anchor point is the origin (usually the top-left corner).
@param obj A UIView or a subclass of UIView.
@param coord Target point.
@param offsetFromOrigin Offset X and Y from actual origin.
@see moveView:toPoint:
@see resizeView:toSize:
*/
+ (void)moveView:(UIView *)obj toPoint:(CGPoint)coord withOffsetFromOrigin:(CGPoint)offsetFromOrigin {
if (!obj) { return; }
CGPoint newCoord = CGPointMake(coord.x + offsetFromOrigin.x, coord.y + offsetFromOrigin.y);
CGRect r = obj.frame;
r.origin = newCoord;
obj.frame = r;
}
