ios - 在页 footer 分创建按钮并检测正确的点击

Question

我有一个带有按钮的节页脚，但我不知道如何检测在我的 TableView 中单击了哪个节页脚。我知道我必须使用“标签”之类的东西，但如何使用？

-(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"]];

感谢您的宝贵时间!

Answer 1

您将发件人转换为按钮并阅读标签:

- (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"]];
}

希望这对您有所帮助。
