Calling a View from a UItableViewCell

Question

I am trying to make my very first app. I have 6 files:

LeftPanelViewController.h LeftPanelViewController.m LeftPanelViewController.xib ForecastViewController.h ForecastViewController.m ForecastViewController.xib

Inside LeftPanelViewController.xib i have a view that contains a table view. i want to set a cell from the table view that i have in LeftPanelViewController.xib so when i press that cell i'll be able to call the view that i have inside the ForecastViewController.xib.

below the code the i have in LeftPanelTableViewController.m

#import "LeftPanelViewController.h"
#import "ForecastViewController.h"


@interface LeftPanelViewController ()

@property (nonatomic, weak) IBOutlet UITableView *myTableView;
@property (nonatomic, weak) IBOutlet UITableViewCell *cellMain;
@property (copy, nonatomic) NSArray *MRP;

@end

@implementation LeftPanelViewController

- (void)viewDidLoad
{
[super viewDidLoad];

Array = [[ NSMutableArray alloc] init];
[Array addObject:@"Forecast"];
[Array addObject:@"Inventory"];

}

- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section
{
return [Array count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
SimpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:SimpleTableIdentifier];

//add an image to the tablecell
UIImage *image = [UIImage imageNamed:@"Icon.png"];
cell.imageView.image = image;

}
cell.textLabel.text = [Array objectAtIndex:indexPath.row];

if (indexPath.row < 7) {
cell.detailTextLabel.text = @"Account";
} else {
cell.detailTextLabel.text = @"Settings";
}
return cell;
}

Answer 1

Even if modal controller did the trick, it may be not what you want. Nothing was happening because your view controller is nil. Probably you are using "Single view app" template from xCode and it has no navigation controller. If you want one, you should create it like [[UINavigationController alloc] initWithRootViewController:] and set your's window root controller to newly created navigationcontroller.

Answer 2

Instead of

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

use

[self presentViewController:Forecast animated:YES completion:nil];
