Hi I’m trying to push to a different view depending what a user selects. I have a table view with 4 other view controllers linked to it via push segues in the story board. All Segues are linked directly to the TableView view controller. Depending on what cell is selected, it loads the corresponding view. Heres the code I’m using:
-(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;
}
}
For some reason
[self.driverDetailView performSegueWithIdentifier:@"pushDriver" sender:dictionary];
NSLog(@"Push Driver");
won’t allow me to set as “Self” at the beginning, i get a error saying:
No Visible @interface for TableCell declares the selector
performSegueWithIdentifier
If i use “self.driverDetailView” i don’t get a error, but when i select the cell nothing happens.
Heres the HorizontalTableView.h
#import <UIKit/UIKit.h>
#import "HorizontalDetailView.h"
#import "HorizontalTableCell.h"
@interface HorizontalTableView : UITableViewController <UITableViewDelegate, UITableViewDataSource> {
NSDictionary *_articleDictionary;

If I understand you correctly, you have your segues hooked up to table view cells. If that’s right, I would suggest hooking them from the view controller itself to the destination view controllers and then calling
[self performSegueWithIdentifier:@"pushDriver"];in yourdidSelectRowAtIndexPath:method.
