目標c - 滾動表格視圖時出現奇怪的泄漏

Question

當我滾動表格視圖時，儀器出現此泄漏。
我做的滾動越多，我得到的泄漏就越多，而且這發生在我的應用程序的每個表格視圖中。

有人可以告訴我我在做什麼錯嗎？

這是表視圖的viewController .m文件：

@implementation ContactsViewController 
@synthesize data = _data; 
@synthesize tableView = _tableView; 

- (void)dealloc 
{ 
    [_data release]; 
    [_tableView release]; 

    [super dealloc]; 
} 

- (void)viewDidLoad 
{ 
    [super viewDidLoad]; 
    // Do any additional setup after loading the view. 

    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bg411.png"]]; 
    self.title = @"Contacts"; 


    // init tableView 
    CGRect tableFrame = self.view.bounds; 

    _tableView = [[UITableView alloc] initWithFrame:tableFrame style:UITableViewStylePlain]; 
    _tableView.backgroundColor = [UIColor clearColor]; 
    _tableView.delegate = self; 
    _tableView.dataSource = self; 
    _tableView.separatorStyle = UITableViewCellSeparatorStyleNone; 


    [self.view addSubview:_tableView]; 

    // load data 
    self.data = [self loadData]; 
} 

- (NSArray *)loadData 
{ 
    NSArray *data = [NSArray arrayWithObjects:@"1", @"2", @"3", nil]; 
    return data; 
} 

- (void)viewDidUnload 
{ 
    [super viewDidUnload]; 
    // Release any retained subviews of the main view. 

    self.tableView = nil; 
} 

#pragma mark - UITableViewDataSource 

- (NSInteger)numberOfRowsInOnlySection 
{ 
    return self.data.count; 
} 

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{ 
    // Return the number of sections. 
    return 1; 
} 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    // Return the number of rows in the section. 
    return [self numberOfRowsInOnlySection]; 
} 

- (void)configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath 
{ 
    NSString *currData = [self.data objectAtIndex:indexPath.row]; 

    cell.textLabel.text = currData; 
} 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *CellIdentifier = @"SingleCell"; 

    UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 

    if (cell == nil) { 
     cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];   
    } 

    [self configureCell:cell atIndexPath:indexPath]; 

    return cell; 
}

我敢打賭，它發生在你的一些UIScrollViewDelegate方法，可能在scrollViewDidEndDragging:willDecelerate。

嘗試運行分析來自己解決大多數顯而易見的問題。
