select a row from view when a push notification is received

Question

I am trying to select a row from a table view when a push notification is received.

I have myprojectAppDelegate.h

#import <UIKit/UIKit.h>
#import "iw.h"
#import "Bookmark.h"


@interface myprojectAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
    UIWindow               *window;
    UITabBarController     *tabBarController;
    UINavigationController *navigationController;
    NSMutableArray                  *tableData;
    NSMutableArray                  *imagesList;
    IBOutlet Bookmark               *tableCell;
}

@property (nonatomic, retain) IBOutlet UIWindow               *window;
@property (nonatomic, retain) IBOutlet UITabBarController     *tabBarController;
@property (nonatomic, retain) IBOutlet UINavigationController *navigationController;
@property(nonatomic, retain) NSMutableArray                  *tableData;
@property(nonatomic, retain) NSMutableArray                  *imagesList;

- (BOOL)getIsLaunched;
- (void)showService;
- (void)showMessage;
- (void) loadLogoList;
+ (const NSString*)getVersion;
+ (const NSString*)getXMLversionURL;
+ (NSMutableDictionary *)logos;
+ (void)setLogos:(NSMutableDictionary *)newDictionary;
- (void)checkVersion;

@end

and implementing the didReceiveRemoteNotification in myprojectAppDelegate.m file But the tableview is implemented in another class bookmarklist.m when the app start after launch options it navigates to bookmarklist.m and displays the table view.

I want to access that tableview which is in bookmarklist.m and select a row in the table when ever i receive a push notification.

please help me with this. i am new to ios programming.

Thanks.

Use the UITableView class method:

- (UITableViewCell *)cellForRowAtIndexPath:(NSIndexPath *)indexPath

This will return the cell at the indexPath you give it.

If you only want to select the cell, use this class method:

- (void)selectRowAtIndexPath:(NSIndexPath *)indexPath animated:(BOOL)animated scrollPosition:(UITableViewScrollPosition)scrollPosition

i am new if you don't mind could you elaborate or guide me to a link or tutorial? – Vardhan D G Jul 17 '13 at 14:13
You will need to combine the 2 answers. Set up the notification like HRM suggest, use my UITableView methods to select your cell. – Jasper Jul 18 '13 at 06:56

You can add an observer method in your bookmarklist.m class like this

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(newMessageReceived:) name:@"NEWMESSAGE" object:nil];

and add this observer method in the same class

-(void)newMessageReceived:(NSNotification *) notification{
       //Here you can select the row you want to be selected
}

Then in your didReceiveRemoteNotification in appDelegate file, post a notification like this and pass the data you want to post in object parameter.

[[NSNotificationCenter defaultCenter] postNotificationName:@"NEWMESSAGE" object:nil];

Hope this helps.

i am trying your method, do i need to add the first line in tableview method? – Vardhan D G Jul 17 '13 at 14:56
got that thought after adding the comment :P – Vardhan D G Jul 17 '13 at 15:00
and also can i possibly send an integer variable from didReceiveRemoteNotification to this method -(void)newMessageReceived:(NSNotification *) notification? – Vardhan D G Jul 17 '13 at 15:10
