I would like to Integrate Google Analytics Tracking into my IOS APP.
I have integrated Google Analytics Library and Add It To my Application.
Here is my code snippet,
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[UIApplication sharedApplication].statusBarHidden = NO;
[GAI sharedInstance].trackUncaughtExceptions = YES;
[GAI sharedInstance].dispatchInterval = 1;
[GAI sharedInstance].debug=YES;
[[GAI sharedInstance] trackerWithTrackingId:#"UA-43556575-1"];
return YES;
}
Code In my FirstViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.trackedViewName = #"Home";
....
....
}
List of Librarys which i have added, (First i have copied all this library from download folder then added to my project folder and then in Xcode i am taking reference from project folder)
GAI.h
GAITrackedViewController.h
GAITracker.h
GAITransaction.h
GAITransactionItem.h
libGoogleAnalytics.a
Almost 5 days and still stuck with same problem :(
:
Please Help ...
Thank you for reading and thanks in advance.
I think this may be one case.
Your UIViewController class must be a subclass of the GAITrackedViewController class,
#interface FirstViewController : GAITrackedViewController
And Must override these function.
-(void)viewDidLoad
{
[super viewDidLoad];
self.trackedName = #"Home";
// your code here
}
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
// your code here
}
As viewDidLoad and viewDidAppear: are important methods.
And Remember the profile must be for mobile app.

How to achieve this stuff below? Please give me some guidance for it. I describe my issue below.
When I tap home button and remove app from tray and while I am opening app I get the login screen. I know how to use NSUserDefaults well.
But my issue is that when I navigate 3rd or 4th viewController and I press Home Button and remove app from tray, Then whenever I open app than I want to open with last open viewController.
Also same when my app is Crashing and I am opening it again then I want to open app with last open viewController state.
So I just want to know that is that possible or not? If yes, then please guide me how to achieve this stuff.
Thank you
Yes, both cases are possible.
On crash, you can use UncaughtExceptionHandler to perform some code. In you app delegate, register you handler like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
// Other didFinishLaunchingWithOptions code
And add your handler method to the same .m file
void uncaughtExceptionHandler(NSException *exception)
{
// App crashed, save last selected tabbar index to the to the NSUserDefaults
[[NSUserDefaults standardUserDefaults] setInteger:tabBarController.selectedIndex forKey:#"LastSelectedTabbarIndex"];
[[NSUserDefaults standardUserDefaults] synchronize];
}
While app runs, to keep track of last selected tab bar controller, use UITabBarControllerDelegate and save newly selected tabbar's index to NSUserDefaults. Short example:
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController
{
NSUInteger tabIndex = [[tabBarController viewControllers] indexOfObject:viewController];
// I have newly selected index, now save it to the NSUserDefaults
}
This code will save last selected tabbar's index to the NSUserDefaults every time tabbar's selected index changes.
Finally, when you app starts (in your didFinishLaunchingWithOptions), read last saved tabbar index from NSUserDefaults and set tabbar's selected index accordingly
self.tabBarController.selectedIndex = lastSelectedIndexFromDefaults;
Edit:
If you also need to restore UINavigationControllers controllers stack, its pretty difficult task. I give you just a quick overview what comes to my mind.
There are 2 cases:
You have custom view controllers initializers and need to pass custom object to those controllers - In this case, its almost impossible (in some reasonable time) implement this
You use only -init or -initWithNibName...: to initialize view controllers in navigation stack. You could enumerate controllers from the root UINavigationController of the tab, get their classes names using NSStringFromClass and save them to NSUserDefaults. On apps start, you would reverse procedure (initialize controllers using their names strings read from NSUserDefaults using something like this: UIViewController *vc = [[NSClassFromString(#"aa") alloc] init];).
I understand you are ok with the code part so i will just give my suggestion
on viewDidLoad of every view controller set a nsuserdefault value of the top most object on navigation array.
if their are not too many branches then you can manage the push at root view controller easily
This is not the proper answer but you can use it for Navigating view after launching.
In AppDelegate file use below codes:---
#import "NewSAppDelegate.h"
#import "NewSViewController.h"
static NewSAppDelegate *globalSelf;
#implementation NewSAppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[NewSViewController alloc] initWithNibName:#"NewSViewController" bundle:nil];
self.navController=[[UINavigationController alloc] initWithRootViewController:self.viewController];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
globalSelf=self;
NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
return YES;
}
void uncaughtExceptionHandler(NSException *exception)
{
UIViewController *currentVC = globalSelf.navController.visibleViewController;
[[NSUserDefaults standardUserDefaults] setObject:NSStringFromClass(currentVC.class) forKey:#"lastVC"];
}
- (void)applicationDidEnterBackground:(UIApplication *)application
{
UIViewController *currentVC = self.navController.visibleViewController;
[[NSUserDefaults standardUserDefaults] setObject:NSStringFromClass(currentVC.class) forKey:#"lastVC"];
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
[[NSNotificationCenter defaultCenter] postNotificationName:#"appDidBecomeActive" object:nil];
// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}
In your login viewController's init method add an observer for notification and in notification method , you can apply if conditions for viewController's name received.and push to that viewController on launching LoginView controller as:---
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(openLastVC)
name:#"appDidBecomeActive"
object:nil];
// Custom initialization
}
return self;
}
-(void)openLastVC
{
NSLog(#"val ==%#",[[NSUserDefaults standardUserDefaults] valueForKey:#"lastVC"]);
if ([[[NSUserDefaults standardUserDefaults] valueForKey:#"lastVC"] isEqualToString:#"GhachakViewController"]) {
GhachakViewController *gvc=[[GhachakViewController alloc] initWithNibName:#"GhachakViewController" bundle:nil];
[self.navigationController pushViewController:gvc animated:NO];
}
}
May this help you....
I followed the instructions in the read me file exactly, but for some reason, in my app, every time I hit the UIButton corresponding to the code to play the sound "[soundA play]; the app just crashes without any detailed error description except for lldb. I'm using Finch because it plays the audio using OpenAL, and I need to use OpenAL for the type of app I'm making because AVAudioPlayer or System Sounds are not usable for what I'm making. Here is the code that I am using.
Main file:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
soundFactory = [[FIFactory alloc] init];
engine = [soundFactory buildSoundEngine];
[engine activateAudioSessionWithCategory:AVAudioSessionCategoryPlayback];
[engine openAudioDevice];
soundA = [soundFactory loadSoundNamed:#"1.caf" maxPolyphony:16 error:NULL];
soundB = [soundFactory loadSoundNamed:#"2.caf" maxPolyphony:16 error:NULL];
soundC = [soundFactory loadSoundNamed:#"3.caf" maxPolyphony:16 error:NULL];
soundD = [soundFactory loadSoundNamed:#"4.caf" maxPolyphony:16 error:NULL];
}
- (void)viewDidUnload
{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
} else {
return YES;
}
}
- (IBAction) PlaySoundA {[soundA play];}
- (IBAction) PlaySoundB {[soundB play];}
- (IBAction) PlaySoundC {[soundC play];}
- (IBAction) PlaySoundD {[soundD play];}
#end
Header file:
#import <UIKit/UIKit.h>
#import "FISoundEngine.h"
#import "FIFactory.h"
#import "FISound.h"
#interface ViewController : UIViewController {
FIFactory* soundFactory;
FISoundEngine* engine;
FISound* soundA;
FISound* soundB;
FISound* soundC;
FISound* soundD;
}
#end
Any help would be appreciated! Thanks!
Most likely the sound player cannot find your sound file. try right clicking on the audio file and selecting view in finder. make sure the file is actually in your project directory and not
I need to change a data (a label) from the app's delegate method ApplicationDidEnterForeground without allocating a new view. The view is called "Reminder", so I imported it into the delegate and I can access its data only if I allocate it (Reminder *anything = [Reminder alloc...etc), but since I want to change the current view loaded I need to have direct access to the view that's already loaded.
How would I do to change the main view's label from the delegate as soon as my application enters foreground?
obs: I know I can do it on -(void)ViewDidLoad or -(void)ViewWillAppear but it won't solve my problem, since it won't change the label if, for example, the user opens the app through a notification box (slide icon when phone is locked). In that case, none of the above methods are called if the app was open in background.
I don't know if I was clear, hope I was. Thank you in advance.
IF you are using storyboards, you can do this to access the current view being seen
- (void)applicationDidEnterBackground:(UIApplication *)application
{
UINavigationController *a=_window.rootViewController;
Reminder *rem = a.topViewController;
rem.label.text=#"test";
}
IF not using story boards
When I create views that I need to access later, I define them as a property, like this
on AppDelegate.h
//#interface SIMCAppDelegate : UIResponder <..........>
//{
//Some variables here
//}
//Properties here
#property (strong, nonatomic) Reminder *reminder;
//Some method declaration here
//eg: -(void) showSomething;
on AppDelegate.m
//#implementation AppDelegate
#synthesize reminder;
so when I alloc/init the view like this
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//codes before here
self.reminder = [[Reminder alloc] init];
self.reminder.label.text = #"OLD LABEL";
//codes after here
}
I will be able to access it again after allocation on other methods, like this
- (void)applicationWillEnterForeground:(UIApplication *)application
{
self.reminder.label.text = #"NEW LABEL";
}
just send a notification from your ApplicationDidEnterForeground: method and receive it on that class where you want to update the label... Like this..
//Your ApplicationDidEnterForeground:
[[NSNotificationCenter defaultCenter] postNotificationWithName:#"UpdateLabel" withObject:nill];
and add observer in it viewDidLoad: of that controller where you want to update label
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(updateLabel:)
name:#"UpdateLabel"
object:nil];
made your method in same class ...
- (void)updateLabel:(NSNotification *)notification{
update label
}
Might be you can try following code -
NSMutableArray *activeControllerArray = [self.navigationController.viewControllers mutableCopy];
for (int i = 0; i< [activeControllerArray count]; i++) {
if ([[activeControllerArray objectAtIndex:i] isKindOfClass:[Reminder Class]) {
Reminder *object = [activeControllerArray objectAtIndex:i];
//Perform all the task here which you want.
break; //Once found break the loop to do further processing.
}
}
I am trying to make an app that contains a class that is created in the app delegate.
I initialize it with:
Mobile *tmp = [[Mobile alloc] init];
mobile = tmp;
[tmp release];
and then I try to use it in other classes in my app with this:
projectAppDelegate *delegate = (projectAppDelegate *)[[UIApplication sharedApplication] delegate];
mobile = delegate.mobile;
but when I do something like:
[mobile enter:x :y];
it crashes...
Is there something I did wrong, or is there any solution for making a class that all the other classes in the app can use?
Thank you.
If you want to use instances of your object you have to store them as properties of app delegate.
//appdelegate.h
//
//...
//
#interface AppDelegate : NSObject <UIApplicationDelegate> {
Mobile *tmp;
}
//...
//appdelegate.m
//
//...
//
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
mobile = [[Mobile alloc]init];
}
//...
- (void)dealloc {
[mobile release];
[super dealloc];
//...
}
Than you have to get a pointer to your application delegate shared instance and call your mobile property.
//... Somewhere
AppDelegate* ref = (AppDelegate*) [[UIApplication sharedApplication] delegate];
NSLog(#"%#", [ref mobile]);
//...
In your first code snippet you are effectively creating and immediately destroying the object. If the object is supposed to persist after that method is done executing you should just use
mobile = [[Mobile alloc] init];
I am working on in-app purchase. In my application we added the following code in appdelegate:
#import "InappPurchaseAppDelegate.h"
#import "MainController.h"
#import "MKStoreManager.h"
#import "MKStoreObserver.h"
#implementation InappPurchaseAppDelegate
#synthesize window;
- (void)applicationDidFinishLaunching:(UIApplication *)application
{
[MKStoreManager sharedManager];
navigationController = [[UINavigationController alloc] init];
[window addSubview:navigationController.view];
MainController *frontController =[[MainController alloc] init];
[navigationController pushViewController:frontController animated:NO ];
[frontController release]; // Override point for customization after application launch
[window makeKeyAndVisible];
}
and added the following code in our controller:
#import "MainController.h"
#import "MKStoreManager.h"
#import "MKStoreObserver.h"
#import "InappPurchaseAppDelegate.h"
#implementation MainController
-(IBAction)InappPurchase:(id)sender
{
[[MKStoreManager sharedManager] buyFeatureA];
}
I also added storekit framework but when the button is clicked nothing happens.
All you need to know is here: http://developer.apple.com/iphone/library/documentation/NetworkingInternet/Conceptual/StoreKitGuide/Overview%20of%20the%20Store%20Kit%20API/OverviewoftheStoreKitAPI.html#//apple_ref/doc/uid/TP40008267-CH100-SW1
It shouldn't take you more than half a day to implement it (maybe a bit more if the content resides on your servers and is not already in the bundle).
The simplest explaination is that your button is not properly configured to send the action message. To test either set a breakpoint for the method or log it like:
-(IBAction)InappPurchase:(id)sender
{
NSLog(#"Buyid method called");
[[MKStoreManager sharedManager] buyFeatureA];
}
If the NSLog or breakpoint are never hit, you need to check the button in Interface Builder and make such it's action is set to the InappPurchase method.
If the InappPurchase method is being called by the button then the problem is in the MKStoreManger object.
