swift - animate different buttons to the correct location -


how can animate different buttons? make 16 buttons in loop:

for in 1..<17 {     if(i == 5 || == 9 || == 13){         added = 0         movetobottom += 60     }     var button = uibutton(frame: cgrectmake(cgfloat(int(middlewidth) + added), cgfloat(movetobottom), 50, 50))     self.view.addsubview(button)      uiview.animatewithduration(2, animations:{         button.frame = cgrectmake(cgfloat(int(middlewidth) + added), cgfloat(int(middleheight) + movetobottom), 50, 50)     },completion: nil ) }

and animate them correct place, buttons on exact same time animation. not want, buttons must animate on different times location, how can that?

do means add animation button 1 one ?

try function, , configure delay parameter.

uiview.animatewithduration(duration: nstimeinterval, delay: nstimeinterval, options: uiviewanimationoptions, animations: { () -> void in   // animate code... }, completion:   // completion block .... )

in condition, write instead:

uiview.animatewithduration(2, delay: 2*(i-1), options: uiviewanimationoptions.curvelinear, animations: { () -> void in     button.frame = cgrectmake(cgfloat(int(middlewidth) + added), cgfloat(int(middleheight) + movetobottom), 50, 50) }, completion: nil)
