嗨，我正在尝试根据用户的选择推送到其他视图。我有一个表格视图，还有其他4个通过故事板中的推送链接链接到它的视图控制器。所有Segues都直接链接到TableView视图控制器。根据所选的单元格，它会加载相应的视图。这是我正在使用的代码：
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSDictionary *dictionary = [_articles objectAtIndex:indexPath.row];
NSArray *selectedKey = [dictionary objectForKey:@"Key"];
if ([selectedKey isEqual:@"Driver"]){
self.driverDetailView.wikiItem = dictionary;
[self.driverDetailView performSegueWithIdentifier:@"pushDriver" sender:dictionary];
NSLog(@"Push Driver");
}
if ([selectedKey isEqual:@"Team"]) {
NSLog(@"Push Team");
}
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
NSLog(@"Preparing For Segue");
if ([[segue identifier] isEqual:@"pushDriver"]) {
self.driverDetailView=segue.destinationViewController;
}
}
因为某些原因
[self.driverDetailView performSegueWithIdentifier:@"pushDriver" sender:dictionary];
NSLog(@"Push Driver");
一开始将不允许我设置为“ Self”，但我收到一条错误消息：
TableCell没有可见的@interface声明选择器
performSegueWithIdentifier
如果我使用“ self.driverDetailView”，则不会出现错误，但是当我选择单元格时，什么也不会发生。

最佳答案
如果我对您的理解正确，那么您的选择就与表格视图单元格挂钩。如果是正确的话，我建议将它们从视图控制器本身挂接到目标视图控制器，然后在[self performSegueWithIdentifier:@"pushDriver"];方法中调用didSelectRowAtIndexPath:。
关于ios - performSegueWithIdentifier根本不起作用，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/10305842/
