objective c - How to release or hide UIImageView in iOS? hidden is not working -

my purpose when drag object, small uiimageview shows, when touch ended, uiimageview released.

- (ibaction)tlmove:(uipangesturerecognizer *)sender {  //add uiimage view show scaled dot uiimageview *scaleupview = [[uiimageview alloc] initwithframe:cgrectmake(200, 30, 100, 100)] ; scaleupview.layer.zposition = 300 ; [scaleupview setimage:self.originimage] ; [self.view addsubview:scaleupview] ;  self.topleftpoint.center = [sender locationinview:self.topleftpoint.superview] ;  targettl = self.topleftpoint.center  ;  if (sender.state == uigesturerecognizerstateended || sender.state == uigesturerecognizerstatecancelled || sender.state == uigesturerecognizerstatefailed) {     [scaleupview sethidden:yes] ; // not working still shows     [scaleupview removefromsuperview] ; //not working still shows } } 

but not working @ all, tried scaleupview.hidden =yes, still not working. scaleupview show, want deallocated in arc mode, can't release when enabling reference counting.

u can set alpha = 0. , u must check ure inside if statments.

so ure code might this:

if (sender.state == uigesturerecognizerstateended || sender.state == uigesturerecognizerstatecancelled || sender.state == uigesturerecognizerstatefailed) {     nslog(@"inside if statement"); \\      [scaleupview setalpha:0] ;      [scaleupview removefromsuperview] ;  } 

hope helps .
