iphone - 无法设置文本标签单元格

Question

这是我的代码

@property (nonatomic,retain) NSMutableArray *category;

@synthesize category;

NSString * path = [[NSBundle mainBundle] pathForResource:@"categorylist" ofType:@"txt"];
    NSString * content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:NULL];
    self.category = [NSMutableArray arrayWithArray:[content componentsSeparatedByString:@"\n"]];
    [content release];

这里有错误

cell.textLabel.text = [category objectAtIndex:[indexPath row]];
    cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
    return cell;

我是新手。所以请帮我找出解决方案。

vvv来自许多帮助这是最终确定解决方案代码。

@property (nonatomic,retain) NSMutableArray *category;

@synthesize category;

NSString * path = [[NSBundle mainBundle] pathForResource:@"categorylist" ofType:@"txt"];
    NSString * content = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:NULL];
    self.category = [NSMutableArray arrayWithArray:[content componentsSeparatedByString:@"\n"]];

这里

cell.textLabel.text = [NSString stringWithFormat:@"%@",[self.category objectAtIndex:indexPath.row]];

不要发布内容。如果您没有使用alloc、new、retain或copy，则不允许释放。

您应该阅读 Memory Management Programming Guide再次
