Question

告诉我，我打算打赌一周，因为单击一个单元格会打开详细视图。

NSArray *MyArray = @[@"hi1",@"hi2",@"hi3"];

我打开故事板，添加一个新视图，使用storyboard segue中的推送（已弃用）适合ID创建链接，但下一步是什么？因为我找不到初学者创建债券的代码。

PS为了以防万一，我完全传播了我的代码

     static NSString *cellIdentifier;
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation{
    _startLocation = newLocation;
