我有一个uitableview在滚动时崩溃。
我已经尝试过泄漏并进行构建和分析，但无法解决这个问题。
得到以下错误
*** -[CALayer retain]: message sent to deallocated instance 0xe192280

你实际上并没有重复使用任何单元格，因为你正在单元格内做所有部分== nil code bloack，更改类似的代码
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UIFont *font = [UIFont fontWithName:@"Arial" size:13];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
UILabel* lblColon = [[UILabel alloc] initWithFrame:CGRectMake(135, 10, 5, 20 )];
lblColon.font = font;
lblColon.backgroundColor = [UIColor clearColor];
lblColon.textColor = [UIColor blackColor];
lblColon.text = @":";
[lblColon setTag:222];
[cell.contentView addSubview: lblColon];
[lblColon release];
}
NSInteger row = [indexPath row];
UILabel* lblToReuse = (UILabel*)[cell.contentView viewWithTag:222];
if (tableView == tblCompanyDetails) {
//usual things you were doing earlier
}
return cell;
}
可能对你有所帮助。检查它是否在用此替换代码后仍然崩溃。

你在哪里发布你要分配的所有对象？看起来你试图一遍又一遍地分配相同的对象。
尝试以下方法：
UILabel *lblTitle = [[[UILabel alloc] initWithFrame: cellRect1] autorelease];
答案 2 :(得分：0)
首先，重用单元格的机制在您的代码中不起作用，因为您执行：
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// ...
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
您正在尝试重复使用标识符为“Cell”的单元格？但是当您创建单元格时，您可以使用reuseIdentifier“MyIdentifier”创建它。这不好。您应该使用相同的标识符创建单元格：
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
并在if (cell == nil) {语句之外移动您的部分以单独配置单元格（取决于indexPath）。在此声明中，您应该只对单元格进行全局配置。此处为此tanle视图中的所有单元格配置相同的内容。因为这个细胞将被重复用于其他细胞。
当我们对单元格使用重用机制时，它会尝试查找带有标识符的单元格（调用[tableView dequeueReusableCellWithIdentifier:CellIdentifier]）。如果找不到，则创建具有相同标识符的单元原型
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
}
在此部分代码之后放置当前单元格的特定代码（在指定的indexPath处）
