我已经检查了我的编译源,那里没有重复项,但我仍然收到此错误。 我是 IOS 的新手,请有人帮忙。 我正在尝试在 View Controller 中创建数组,然后使用 segues 将其传递给另一个 View Controller 。
ViewController.m :
-(IBAction)click:(id)sender
{
self.ArrayInput = [[NSMutableArray alloc]init];
[self.ArrayInput addObject:@[_firstname.text]];
[self.ArrayInput addObject:@[_lastname.text]];
[self.ArrayInput addObject:@[_Email.text]];
NextViewController * nextcontroller = (NextViewController *)[self.storyboard instantiateViewControllerWithIdentifier:@"NextViewController"];
[self.navigationController pushViewController:nextcontroller animated:YES];
}
然后在 ViewController.m 中使用 segue:
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
NextViewController * NextVC = (NextViewController *)segue.destinationViewController;
NextVC.NextArray = [NSMutableArray arrayWithArray:self.ArrayInput];
}
NextViewController.m:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath
{
myTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"myTableViewCell" forIndexPath:indexPath];
cell.Data.text = [self.NextArray objectAtIndex:indexPath.row];
return cell;
}
最佳答案
这个错误经常发生是不小心导入了 .m 文件而不是 .h
或
步骤:
- 检查 Target 设置中的构建阶段。
- 检查任何文件是否存在两次或一次。
- 如果文件存在两次,删除一个。
关于ios - 代码 7 : linker command failed with exit code 1 (use -v to see invocation),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/35425628/
