表导致Apple Watch崩溃

Question

当我尝试使用以下代码启动Apple Watch应用程序时，它会在日志打印后崩溃并生成＆＃34; （之后什么也没有）。当我删除代码时，它不会崩溃。我无法弄清楚可能出现的问题。

 NSMutableArray *rowTypesList = himo; //himo is a nsmutablearray that contains info from NSXMLParser
        [_table setRowTypes:rowTypesList];
        for (NSInteger i = 0; i < _table.numberOfRows; i++)
        {
            NSDictionary *itemAtIndex =(NSDictionary *)[himo objectAtIndex:i];
            NSObject *row = [_table rowControllerAtIndex:i];
            Cell *importantRow = (Cell *) row;
            [importantRow.label setText:@"hi"];
        }
NSLog(@"produce");

看起来您要将要显示在表中的数据与行控制器类型混合使用。如果您只有一个单行控制器类型的Cell，您可以通过代码执行以下操作：

[_table setNumberOfRows:[himo count] withRowType:@"theIdentiferYouGaveTheRowControllerInTheStoryboard"];
for (NSInteger i = 0; i < [himo count]; i++) {
    NSDictionary *item = (NSDictionary *)[himo objectAtIndex:i];
    Cell *rowController = [_table rowControllerAtIndex:i];
    [rowController.label setText:@"hi"]; // you probably want to use the data from item here
}
