Creating a new object when a UIlabel is dragged and dropped on another using the Pan gesture recognizer

Creating a new object when a UIlabel is dragged and dropped on another
using the Pan gesture recognizer

i have a UIlabel on my view... i want to create another object when i drag
another UIlabel onto the previous UIlabel on the view. it should work in a
way that when i drag the label onto the previous one and drop it on the
previous UIlabel, it creates the object. the code i have doesnt recognize
the UIGestureStateEnded. it creates the object when i drag it across the
UIlabel. it doesnt wait for me to drop it on the UIlabel. this is the code
below. any help will be appreciated.

isRelationship; entity *mergedEntity; entity * currentSender=(entity*)
paramSender.view;

paramSender.state != UIGestureRecognizerStateFailed) { CGPoint location =
[paramSender locationInView:paramSender.view.superview];
paramSender.view.center = location; currentSender.layer.borderColor =
[UIColor greenColor].CGColor; currentSender.layer.borderWidth = 3.0;
}

CGPoint location =
[paramSender locationInView:paramSender.view.superview];
