Ios 如何通过单击UITableViewCell发送数据'；s按钮到另一个ViewController

我想使用uitableviewcell中的按钮单击发送数据。我从web服务获取数据。每行按钮向viewController发送不同的数据。 将CellForRowatinex方法附加到下面：

-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(nonnull NSIndexPath *)indexPath {

static NSString *identifier = @"CategoryCell";
NSDictionary *dictMenuData = [_arrHandMadeList objectAtIndex:indexPath.row];
CategoryCell *cell = (CategoryCell *)[tableView dequeueReusableCellWithIdentifier:identifier];

if(!cell) {
    [tableView registerNib:[UINib nibWithNibName:@"CategoryCell" bundle:nil] forCellReuseIdentifier:identifier];
    cell = (CategoryCell *)[tableView dequeueReusableCellWithIdentifier:identifier];
}

cell.btnShowRatingDetails.tag = indexPath.row;
[cell.btnShowRatingDetails addTarget:self action:@selector(showRatingClicked:) forControlEvents:UIControlEventTouchUpInside];

[arrReview removeAllObjects];
//arrReview = [dictMenuData objectForKey:@"RivewData"];
[arrReview addObjectsFromArray:[dictMenuData objectForKey:@"RivewData"]];

[cell setupHandMadeCell:dictMenuData];

return cell;
}

按钮的使用方法如下：

-(void) showRatingClicked:(UIButton*)sender {

//if (sender.tag == currentIndex) {
ReviewVC *rvc = (ReviewVC*)[self.storyboard instantiateViewControllerWithIdentifier:@"ReviewVC"];

rvc.arrReviewDetails = arrReview;
rvc.strRestaurentName = [dictMenuData objectForKey:@"Restaurant_Name"];
rvc.strRestaurentId = [dictMenuData objectForKey:@"Restaurant_Id"];
rvc.strRestaurentRating = [dictMenuData objectForKey:@"Stars"];

[self.navigationController pushViewController:rvc animated:YES];
//}
}

请帮帮我

提前感谢

您需要使用

NSDictionary*dictReview=[\u arrsandelist objectAtIndex:sender.tag]-（void）showrating中单击：（UIButton*）sender

以获取适当的词典，然后在

dictMenuData

处使用它

从代码中完全删除

dictMenuData

。

您需要获取所选单元格按钮的索引。您可以从sender.tag获取它

-(void) showRatingClicked:(UIButton*)sender {

ReviewVC *rvc = (ReviewVC*)[self.storyboard instantiateViewControllerWithIdentifier:@"ReviewVC"];

NSDictionary *dictMenuData = [_arrHandMadeList objectAtIndex:sender.tag];

rvc.arrReviewDetails = [dictMenuData objectForKey:@"RivewData"]; //or as per your data
rvc.strRestaurentName = [dictMenuData objectForKey:@"Restaurant_Name"];
rvc.strRestaurentId = [dictMenuData objectForKey:@"Restaurant_Id"];
rvc.strRestaurentRating = [dictMenuData objectForKey:@"Stars"];

[self.navigationController pushViewController:rvc animated:YES];

}

一旦

cell.btnShowRatingDetails.tag=indexPath.row

按钮被分配了一个标记，您可以在action方法中获取数据对象，与使用

indexpath.row

获取数据对象的方式相同

它的可能副本只发送tableviewIts的最后一个索引，因为您正在CellForRowAtIndexPath中重新填充数组，很高兴它有帮助。：）
