- (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.
}
}
在這裡 myArray 是一個數組 是資料成員 並且我已經alloc,但是當我在模擬器中橫掃的時候老是在remove那裡報錯,報的這個錯

解決辦法:
數組應該初始化稱NSMutableArray 我定義成NSArray 了
NSMutablearray * myarray = [[NSMutableArray alloc] init];
