UITableView行 - 通過選擇另一行取消選擇和更改高亮：否

Question

我只是在學習所有這些東西，所以如果我犯了一個明顯的錯誤，請原諒。

我有一系列專業知識水平：@ [@「NOVICE」，@「INTERMEDIATE」，@「PRO」，@「所有水平」];

用戶最多可以選擇兩個，但是如果選擇了所有等級，則執行繼續並保存設置。

我想避免的是用戶選擇NOVICE和PRO。如果NOVICE被選中，我想PRO被取消選中並且不被注意。反之亦然。

這裏是我的，但我得到的錯誤：

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 
NSString *organizeLevelOfPlay = self.organizeDifficultyArray[indexPath.row]; 

if ([organizeLevelOfPlay isEqualToString:@"ALL LEVELS"]){ 
    [self performSegueWithIdentifier:@"MinimumNumberOfPlayers" sender:self]; 

} else if ([organizeLevelOfPlay isEqualToString:@"NOVICE"]){ 
    [self.organizeDifficultyArray[2] setHighlighted:NO animated:YES]; //I get an error here. 
    [self.selectionArray removeObject:self.organizeDifficultyArray[2]]; 
    [self.selectionArray addObject:organizeLevelOfPlay]; 
    self.result = [[self.selectionArray valueForKey:@"description"] componentsJoinedByString:@"/"]; 
    NSLog(@"%@", self.selectionArray); 

} else if ([organizeLevelOfPlay isEqualToString:@"INTERMEDIATE"]) { 
    [self.selectionArray addObject:organizeLevelOfPlay]; 
    self.result = [[self.selectionArray valueForKey:@"description"] componentsJoinedByString:@"/"]; 
    NSLog(@"%@", self.selectionArray); 

} else if ([organizeLevelOfPlay isEqualToString:@"PRO"]){ 
    [self.organizeDifficultyArray[0] setHighlighted:NO animated:YES]; //I get an error here. 
    [self.selectionArray removeObject:self.organizeDifficultyArray[0]]; 
    [self.selectionArray addObject:organizeLevelOfPlay]; 
    self.result = [[self.selectionArray valueForKey:@"description"] componentsJoinedByString:@"/"]; 
    NSLog(@"%@", self.selectionArray); 
}}

嘗試使用 -[tableView: deselectRowAtIndexPath:]功能，以取代-[setHighlighted:NO animated:YES]之一。 @"NOVICE"和@"PRO"可能是indexpath{0,1},indexpath{0,2}。
