您将在何处释放正在分配的所有对象？看起来您正试图一次又一次地分配相同的对象 尝试以下方法：
UILabel *lblTitle = [[[UILabel alloc] initWithFrame: cellRect1] autorelease];
实际上，您没有重用任何单元格，因为您正在执行单元格内的所有部分==nil code bloack，并对代码进行如下更改
- (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;
}
也许能帮你一点忙。用这个替换代码后，检查它是否仍然崩溃。首先，重用单元的机制在代码中不起作用，因为您：
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// ...
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
if（cell==nil）{[tableView dequeueReusableCellWithIdentifier:CellIdentifier]if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:@"MyIdentifier"] autorelease];
}
在这部分代码之后，将当前单元格的特定代码（在指定的indexPath中）如果将值存储在数组/对象中，或者将值存储在UITableViewCell子类中，对您来说不是更容易、编码更少吗？
