  I am newbie in iphone apps i am building a app with 5 UiviewController.
  In my 2nd view a button is placed which points to 3 rd view. There a barcode scanning process held and goes to the 4th view. There is a back button option to come back to 2nd view from 4th view and the process continues...
  
  But after a few moments the 2nd view button is not responding to touch sometimes and the apps gets slow.
  
  
  As well as the the buttons in the 4th view also not working. I have pragmatically created some UI component in those 2, 3, 4th view & init them with CGrectmake and release them also. i also release all the variable in dealloc method when switching from one view to another.
  
  But if i restart my app it's works fine like previous but after a few time of repeatation the same thing happens.
  
  Plz help me out what to do to get the UI button Response all time and make the app faster.:confused:

  
  
  
  in 2nd view controller: (view did load)
  
  
  
  CAGradientLayer *bgLayer = [BackgroundLayer blueGradient];
  bgLayer.frame = self.view.bounds;
  [self.view.layer insertSublayer:bgLayer atIndex:0];
  
  
  
  //scan_book is the button that is not working
  
  
  
  scan_book.multipleTouchEnabled=YES;
  
  [scan_book setExclusiveTouch:NO];
  
  
  
  UINavigationBar *naviBarObj = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
  
  UIButton*backButton =[[UIButton alloc] initWithFrame:CGRectMake(14.0, 0.0, 120.0, 36.0)];
  
  [backButton addTarget:self action:@selector(placeonline:) forControlEvents:UIControlEventTouchUpInside];
  [backButton setTitle:@"Place online " forState:UIControlStateNormal];
  
  CGFloat navBarHeight = 40.0f;
  CGRect frame = CGRectMake(0.0f, 0.0f, 100.0f, navBarHeight);
  [backButton setFrame:frame];
  UIBarButtonItem* backItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
  
  UINavigationItem *navigItem = [[UINavigationItem alloc] initWithTitle:@"Scanned Book"];
  
  label = [[UILabel alloc] initWithFrame:CGRectMake(140.0, 0.0, 120.0, 36.0)];
  navigItem.titleView = label;
  
  navigItem.rightBarButtonItem = backItem;
  
  
  
  [self.view addSubview:naviBarObj];
  
  scan_book.layer.cornerRadius = 5; // this value vary as per your desire
  scan_book.clipsToBounds = YES;
  scan_book.layer.borderColor = [UIColor blackColor].CGColor;
  scan_book.layer.borderWidth = .5f;
  
  
  
  when i go from 2nd to 3rd controller:
  
  
  
  - (IBAction)scan_book:(id)sender {
  EmbedReaderViewController *nextController = [[EmbedReaderViewController alloc] initWithNibName:@"EmbedReaderViewController" bundle:nil];
  nextController.backtitile=tabledata;
  
  [self.view addSubview:nextController.view];
  
  
  
  [self.view release];
  
  }
  
  
  
  
  
  
  in 3rd view controller: view did load
  
  
  
  
  
  UINavigationBar *naviBarObj = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
  
  [naviBarObj setTintColor:[UIColor MyColor]];
  
  UIButton*backButton =[[UIButton alloc] initWithFrame:CGRectMake(14.0, 0.0, 120.0, 36.0)];
  CGFloat navBarHeight = 40.0f;
  CGRect frame = CGRectMake(0.0f, 0.0f, 120.0f, navBarHeight);
  [backButton setFrame:frame];
  UIBarButtonItem* backItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
  UINavigationItem *navigItem = [[UINavigationItem alloc] initWithTitle:@"Scanned Book"];
  UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(120.0, 0.0, 200.0, 36.0)];
  label.text= @"Scan book";
  navigItem.titleView = label;
  
  navigItem.leftBarButtonItem = backItem;
  naviBarObj.items = [NSArray arrayWithObjects: navigItem,nil];
  
  [naviBarObj setTranslucent:YES];
  
  [self.view addSubview:naviBarObj];
  
  
  
  3rd view to 4 th view:
  
  
  
  setprice_screen *nextController = [[setprice_screen alloc] initWithNibName:@"setprice_screen" bundle:nil];
  
  nextController.barcode_no=soapResults;
  nextController.backData=backtitile;
  nextController.camera_barcode=[barcode_bar objectAtIndex:0];
  // nextController.camera_barcode=[NSMutableString stringWithString:camera_barcode];
  [self.view addSubview:nextController.view];
  [self.view release];
  
  
  
  
  
  4th view viewdidload:
  
  
  
  
  
  UINavigationBar *naviBarObj = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
  
  UIButton*backButton =[[UIButton alloc] initWithFrame:CGRectMake(140.0, 0.0, 120.0, 36.0)];
  UIBarButtonItem* backItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
  
  UINavigationItem *navigItem = [[UINavigationItem alloc] initWithTitle:@"Books"];
  
  label = [[UILabel alloc] initWithFrame:CGRectMake(140.0, 0.0, 220.0, 36.0)];
  
  navigItem.titleView = label;
  
  navigItem.leftBarButtonItem = backItem;
  naviBarObj.items = [NSArray arrayWithObjects: navigItem,nil];
  
  [self.view addSubview:naviBarObj];
  
  
  
  
  
  4th view to 2nd view :
  
  - (void) backAction{
  booklist_screen *nextController = [[booklist_screen alloc] initWithNibName:@"booklist screen" bundle:nil];
  
  [self.view addSubview:nextController.view];
  [self.view release];
  }
