同样是删除cell问题，帮我看看问题出现在哪，谢谢！
我的类文件myFile是继承UIViewController的(目的是为了能够在一个view里切换不同的tableView)，在myFile.h中定义一个可变数组editContactsList，然而在IB里面添加了一个view,两个tableView,在下面方法里面报错（有注明具体位置）
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath*)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
// Delete the row from the data source.
NSUInteger row = [indexPath row];
[tableView beginUpdates];
NSLog(@"%@",self.editContactsList);//打印到数组内容
[self.editContactsList removeObjectAtIndex:row];//此处报错，错误信息在下面
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
[tableView endUpdates];
[tableView reloadData];
}
}
错误信息：

麻烦各位大侠帮忙看看，指点指点，本人菜鸟，被它搞到头大了，谢谢

你用的是NSArray吗，要用NSMutableArray。
如果头文件定义的editContactsList是NSMutableArray类型，那在初始化的时候是不是
self.editContactsList = [[NSArray alloc] init]把他初始化成了NSArray呢![__NSArrayI removeObjectAtIndex:]: unrecognized selector sent to instance](/default/index/img?u=aHR0cHM6Ly9iYnNtYXguaWthZmFuLmNvbS9zdGF0aWMvTDNCeWIzaDVMMmgwZEhBdlkyTXVZMjlqYVcxbkxtTnZiUzlpWW5NdmFXMWhaMlZ6TDJKaFkyc3VaMmxtLmpwZw== "__NSArrayI removeObjectAtIndex:]: unrecognized selector sent to instance")
谢谢！确实是这个原因。
我在viewDidLoad里面这样为editContactsList赋值：
NSMutableArray *arr =[ [NSArray alloc] initWithObjects:@"a",@"b",@"c",nil];
self. editContactsList = arr;
[arr release];
就会出现上面的错误，后来改成了下面的方法就通过了：
NSArray *arr = [[NSArray alloc]initWithObjects:@"a",@"b",@"c",nil];
[NSMutableArray arrayWithCapacity:10];
[editContactsList setArray:arr];
[arr release];
