Hi friends I am getting images from webservice and loading these images in table view.But when i continue to scroll the program receives memory warning level1,level2 and then app exits with status 0.That happens only in device not in simulator.
Here is my code which i am putting please help me out.
- (void)viewDidLoad {
[super viewDidLoad];
UIButton *infoButton = [[UIButton alloc] initWithFrame:CGRectMake(0, -4, 62, 30)];

UIBarButtonItem *customBarButtomItem = [[UIBarButtonItem alloc] initWithCustomView:infoButton];
self.navigationItem.leftBarButtonItem = customBarButtomItem;
[customBarButtomItem release];
[infoButton release];
UIButton *homeButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 62, 30)];
[homeButton setBackgroundImage:[UIImage imageNamed: @"home.png"] forState:UIControlStateNormal];
[homeButton.titleLabel setFont:[UIFont systemFontOfSize:11]];
//[homeButton setTitle:@"UPLOAD" forState:UIControlStateNormal];
[homeButton addTarget:self action:@selector(homeButtonClicked) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *rightBarButtom = [[UIBarButtonItem alloc] initWithCustomView:homeButton];
self.navigationItem.rightBarButtonItem = rightBarButtom;
[rightBarButtom release];
