Question

每当我从视图中插入NSString返回到UITableView的数据源时，当插入新单元格的调用被放置时，程序崩溃。以下是代码：

- (void)insertTableObject:(NSString *)thing
{
    if (!locations) locations = [[NSMutableArray alloc] init];
    [locations addObject:[NSString stringWithFormat:@"%@", thing]];
    NSLog(@"%@", locations);
    self.tableContents = [[NSMutableDictionary alloc] initWithObjectsAndKeys:locations,@"", nil];
    self.sortedKeys =[[self.tableContents allKeys] sortedArrayUsingSelector:@selector(compare:)];
    [self.tableView insertRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:([locations count]-1) inSection:0]] withRowAnimation:UITableViewRowAnimationAutomatic];
}

下面是打印出来的数组，以及随之发生的错误：

“la”打印没有引号是一个问题吗？系统可能没有看到该条目吗？

我最终解决了这个问题。我有细节与细节视图，所以当它绘制detailView索引时，它不存在。我在原始帖子中为函数添加了一个简单的行，以便为detailView数组添加另一个值。
