myimageview8 display awesome center of screen:

myimageview8=[[uiimageview alloc]initwithframe:cgrectmake(0, 50, 320, self.view.frame.size.height)]; [self.view addsubview:myimageview8]; myimageview8.userinteractionenabled=yes;  -(void)img:(id)sender {     if(myimageview8){         [myimageview8 removefromsuperview];     }      else {         [myimageview8 addsubview:awesomeview];     } }  -(void)img1:(id)sender {     if(myimageview8) {         [myimageview8 removefromsuperview];     }     else {         [myimageview8 addsubview:awesomeview];     } }  -(void)img2:(id)sender {     if(myimageview8) {         [myimageview8 removefromsuperview];     }     else {     [myimageview8 addsubview:awesomeview];     } }
