爲頁腳創建按鈕並檢測正確點擊

Question

我有一個按鈕的章節頁腳，但我不知道如何檢測在我的TableView中點擊了哪個頁腳。我知道我必須使用「標籤」之類的東西，但是怎麼樣？

-(UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section{ 

self.footerHeartView = [[UIView alloc]initWithFrame:CGRectMake(10, 0, 300, 60)]; 
[self.footerHeartView addSubview:viewFotter]; 

UIView *viewFotter = [[UIView alloc]initWithFrame:CGRectMake(10, 0, 300, 60)]; 

self.heartButton = [[UIButton alloc]initWithFrame:CGRectMake(200, 5, 70, 50)]; 
self.heartButton.tag = section; 
self.heartButton.backgroundColor = [UIColor greenColor]; 
[self.heartButton addTarget:self 
        action:@selector(heartClick:) 
      forControlEvents:UIControlEventTouchUpInside]; 



[viewFotter addSubview:self.heartButton]; 


[viewFotter setBackgroundColor:[UIColor whiteColor]]; 
return self.footerHeartView; 
} 


- (void)heartClick:(UIButton*)sender { 
NSLog(@"CLICK"); 

[[GTAppController sharedInstance].api sendLike:1 itemId:[[self.newsList objectAtIndex:???????]objectForKey:@"testId"]]; 

}

感謝您的時間！

你施放發件人作爲一個按鈕，讀取標籤：

- (void)heartClick:(UIButton*)sender { 
NSLog(@"CLICK"); 
    UIButton* sectionButton = (UIButton*)sender; 
    int section = sectionButton.tag; 

[[GTAppController sharedInstance].api sendLike:1 itemId:[[self.newsList objectAtIndex:???????]objectForKey:@"testId"]]; 
} 

希望這有助於。
