iphone - scrollview not working from database images -

i stored images in local database. fetched images database using sqlite , displayed using array. added image array in scrollview. scrollview not working.

code:

.h file:

nsmutablearray *arraysofs; -(void)unloadpreviouspage:(int)index; -(void)loadnextpage:(int)index; 

.m file:

 -(void)click:(id)sender{           scroll = [[uiscrollview alloc] initwithframe:cgrectmake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];         scroll.pagingenabled = yes;            (int = 0; i<[self.arraysofs count]; i++ ) {             nslog(@"index %d",i);                mmageview=[[uiimageview alloc]initwithframe:cgrectmake(20+(i*74), 420, 72, 72)];             [mmageview setimage:((mysof *) [self.arraysofs objectatindex:i]).photo];             [scroll addsubview:mmageview];            }           [scroll setcontentsize:cgsizemake(cgrectgetmaxx(mmageview.frame),self.view.frame.size.height)];         [self.view addsubview:scroll];       } 

in click methos set content size of scrollview follows,

-(void)click:(id)sender{  (int index = 0; index < [self.arraysofs count]; index ++ ) {          nslog(@"index %d",index);          mmageview=[[uiimageview alloc]initwithframe:cgrectmake(20+(index*74), 52, 72, 72)];          [self.view addsubview:mmageview];          soflistsql * mysofs =[[soflistsql alloc] init];         self.arraysofs = [mysofs getmylists];         [mmageview setimage:((mysof *) [self.arraysofs objectatindex:index]).photo];     }  [your_scrollview setcontentsize:cgsizemake(cgrectgetmaxx(mmageview.frame),self.view.frame.size.height)]; }
