iphone中的tableview编辑崩溃应用程序？

Question

在应用程序中我有自定义 tableview(UITableView *tableView) uiviewcontroller 的子类和在 tableview 编辑中完美显示但是当我删除行时

- (void)tableView:(UITableView *)tableView1 commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

    if (editingStyle == UITableViewCellEditingStyleDelete) {
        // Delete the row from the data source
        //[appDelegate deleteItemAtIndexPath:indexPath];
        [self testing:indexPath];
        [tableView deleteRowsAtIndexPaths:
         [NSArray arrayWithObject:indexPath] 
                     withRowAnimation:UITableViewRowAnimationFade];//in this line app crash 
        NSLog(@"delete row");
        [tableView reloadData];
    }   
    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
        //nothing to do item already added
    }   
} 

当断点到达该行时在此方法中

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

我的应用程序崩溃了我所做的事情。

-(void)testing:(NSIndexPath *)path{

Player *doc = [[Player alloc]init];
NSMutableArray* reversedArray = [[NSMutableArray alloc] initWithArray:[[[[NSArray alloc] initWithArray: _data] reverseObjectEnumerator] allObjects]];

doc = [reversedArray objectAtIndex:path.row];
NSLog(@"%@,%d", doc.name,path.row);
[self deleteRow:doc];

}

-(void)deleteRow:(播放器 *)doc{

//ReferMeAppDelegate *appDelegate = (ReferMeAppDelegate *) [[UIApplication sharedApplication]delegate]; self.party = [PartyParser loadParty]; 如果（_party！= nil）{ for (玩家 *player in _party.players) { NSLog(@"%@, %@", player.name,player.alert); NSComparisonResult resultName, resultEmail, resultPhone, resultLocation; //NSString *str = [appDelegate.plistDict valueForKey:@"flag"]; //if ([player.email length] != 0 && player.alert == @"1"){ resultName = [doc.name compare:player.name]; resultEmail = [doc.email 比较：player.email]; resultPhone = [doc.phone 比较：player.phone]; resultLocation = [doc.location 比较：player.location]; if(resultName == 0 && resultEmail == 0 && resultPhone == 0 && resultLocation == 0){ //lblName1.text = @"equal"; 玩家 *playerr = [[玩家分配]init]; 玩家 = 玩家； [_party.players removeObject:playerr]; //[_party.players removeObjectAtIndex:path.row]; 休息; } // } //if([player.email 长度] == 0 && player.alert == @"2"){ 别的{ resultName = [doc.name compare:player.name]; resultPhone = [doc.phone 比较：player.phone]; if (resultName == 0 && resultPhone == 0) { 玩家 *playerr = [[玩家分配]init]; 玩家 = 玩家； [_party.players removeObject:playerr]; 休息;
} } }

        for (Player *player in _party.players) {
            NSLog(@"after match case player names");
            NSLog(@"%@", player.name);
        }
        [PartyParser saveParty:_party];
    }

}

我在支持读写操作的应用程序中使用 GData xml。

deleteRowsAtIndexPaths: 方法仅执行删除的视觉效果，您还必须手动从数据源中删除相应的项目，以便其中的项目数量与您的操作预期一致，例如：

//You need to remove item from data source
[yourMutableDataArray removeObjectAtIndex:indexPath.row]; 
// Tell table view to remove the corresponding item cell
[tableView deleteRowsAtIndexPaths:
             [NSArray arrayWithObject:indexPath] 
             withRowAnimation:UITableViewRowAnimationFade];//in this line app crash 
NSLog(@"delete row");
//[tableView reloadData]; // You do not need this line
