关于UITableView横扫删除的问题 [NSMutableArray removeObjectAtIndex]

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle
forRowAtIndexPath:(NSIndexPath *)indexPath {

if (editingStyle == UITableViewCellEditingStyleDelete) {

[myArray removeObjectAtIndex:indexPath.row];

[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];

}

else if (editingStyle == UITableViewCellEditingStyleInsert) {

// Create a new instance of the appropriate class, insert it into the array, and add a new row
to the table view.

}

}

在这里 myArray 是一个数组 是数据成员 并且我已经alloc，但是当我在模拟器中横扫的时候老是在remove那里报错，报的这个错

2011-06-08 16:51:56.989 view[749:207] -[__NSArrayI removeObjectAtIndex:]: unrecognized selector sent to
instance 0x4e4b530

*** Call stack at first throw:

解决办法：

数组应该初始化称NSMutableArray 我定义成NSArray
了

NSMutablearray * myarray = [[NSMutableArray alloc] init];
