3D Touch is introduced in iPhone 6s/iPhone 6s plus,and I am wondering if we could have access to 3D Touch related API and do it programmatically in our app.Does anyone has some ideas?
You will have access to 3D touch functionality in apps. There will be a new property, force, in the UITouch class that will hold the strength that a tap event has. 1.0 is defined to be an "average touch".

I am sharing the source code for pressing on app icon populate 4 item in list
Step 1:- Import class in appDelegate.m
import sys/utsname.h

return YES;
}

I am using Tab Bar controller in my app, If want to move in view controlled:
- (void) moveToControllerScene {
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:STORY_BOARD_IDENTIFIER bundle:nil];
YOUR_CONTROLLER_OBJECT *obj = [storyboard instantiateViewControllerWithIdentifier:#"YOUR_CONTROLLER_OBJECT"];
[navController pushViewController:obj animated:YES];
}

I handle push notification when the screen is on by automatically push to a detailViewController. It works fine when there is one or two push notification as I can push each detailViewController on top of each other and pop it back. However, app crash when I have to pop back more than two detailViewControllers. It happens only in iOS 7+.
Set notification Id
- (void)application:(UIApplication *)app didReceiveRemoteNotification:(NSDictionary *)userInfo
{
if(app.applicationIconBadgeNumber!=0)
{
app.applicationIconBadgeNumber = app.applicationIconBadgeNumber - 1;
}
NSString *aps =[NSString stringWithFormat:#"%#",[userInfo objectForKey:#"id"]];
if (app.applicationState == UIApplicationStateActive)
{
NSDictionary *dict = [NSDictionary dictionaryWithObjects:#[[[userInfo objectForKey:#"aps"] objectForKey:#"alert"]] forKeys:#[#"notifyText"]];
[arrNotificationData addObject:dict];
[self showNotificationInActiveMode:[[userInfo objectForKey:#"aps"] objectForKey:#"alert"]];
}
if ([aps isEqualToString:#"1"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
if ([aps isEqualToString:#"2"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
if ([aps isEqualToString:#"3"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
if ([aps isEqualToString:#"4"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}if ([aps isEqualToString:#"5"])
{
[UserDefault setpushnotificationid:[aps intValue]];
}
}
Use singleton class as base class and check for ID and the push and pop the view.
#interface CustomViewController ()
#end
#implementation CustomViewController
- (void)viewDidLoad
{
[super viewDidLoad];
[[NSNotificationCenter defaultCenter]addObserver:self
selector:#selector(appBecomeActive)
name:UIApplicationDidBecomeActiveNotification
object:nil];
}
-(void)appBecomeActive
{
int val=[UserDefault getpushnotificationid];
if(val!=0){
[self checkforpushnotification];
}
}
-(void)checkforpushnotification
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
int val=[UserDefault getpushnotificationid];
[UserDefault setpushnotificationid:0];
//.: if current view is profile or setting just dismiss it.because they are present
switch (val)
{
case 1:
{
if( [self checkIfControllerExist:[DealsViewController class]])
{
return;
}else{
detailViewController *VC = (detailViewController *)[storyboard instantiateViewControllerWithIdentifier:#"VCView"];
[self.navigationController pushViewController:VC animated:YES];
}
}
break;
}
}
Now use bace class in your class
#interface detailViewController : CustomViewController
In an app i am developping I have a view which first appears whenever the user imports a doc to the app. What I want is to have a dialog box appear(could be an UIAlert or Activity sheet menu) asking the user if he really wants to import that file( Yes or cancel). I would like to know how to make the UIAlert/Actionsheet menu appear before the import action is performed, and how to assign an action to be done when user clicks on either Yes or No, or "Change file
The view that appears is called ProgressBarView.m/h. In it is the viewdidload like this:
- (void)viewDidLoad
{
[super viewDidLoad];
self.progressBar.progressTintColor = [UIColor colorWithRed:153.0/255 green:0 blue:0 alpha:1.0];
self.progressBar.progress = 0.0;
/*progressValueLabel = [NSString stringWithFormat:#"%.0f%%", (self.progressBar.progress * 100)];*/
self.progressTimer = [NSTimer scheduledTimerWithTimeInterval:0.3f
target:self
selector:#selector(changeProgressValue)
userInfo:nil
repeats:YES];
}
This is then called in the app delegate when the import starts in the appdidFinishLaunchwith options:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSURL *url = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];
if (url != nil && [url isFileURL]) {
**[self handleImportURL:url];** // this is the function that handles the import
}
The function that does the import and calls the progressView is as follows:
- (void)handleImportURL:(NSURL *)url
{
// Show progress window
UIStoryboard * storyboard = [UIStoryboard storyboardWithName:#"MainStoryboard" bundle:nil];
__block PVProgressViewController * progressController = [storyboard instantiateViewControllerWithIdentifier:#"kProgressViewController"];
self.window.rootViewController = progressController;
// Perform import operation
dispatch_async(dispatch_get_global_queue(0, 0), ^{
NSError *outError;
NSString * csvString = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:&outError];
NSArray * array = [csvString csvRows];
[[PVDatabaseController sharedController] importArray:array progressHandler:^(float progress) {
progressController.progressBar.progress = progress;
}];
dispatch_async(dispatch_get_main_queue(), ^{
self.window.rootViewController = controller;
});
});
}
You could define your NSURL as an ivar, and call your handleImportURL: method in the appropriate clickedButtonAtIndex: method like this:
#implementation AppDelegate{
NSURL *_importURL;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
_importURL = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];
if (url != nil && [url isFileURL]) {
[self confirmImportAlert];
}
}
UIActionSheet:
- (void)confirmImportAlert {
UIActionSheet *myActionSheet = [[UIActionSheet alloc] initWithTitle:#"Your Title" delegate:self cancelButtonTitle:#"Cancel" destructiveButtonTitle:nil otherButtonTitles:#"Yes", nil];
myActionSheet.delegate = self;
[myActionSheet showInView:self.window];
}
-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex == 0){
//initiate import
[self handleImportURL:_importURL];
}
else{
//don't initiate import
}
}
UIAlertView:
- (void)confirmImportAlert {
UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:#"Your Title" message:#"Your Message" delegate:self cancelButtonTitle:#"Cancel" otherButtonTitles:#"Yes", nil];
[myAlertView show];
}
- (void)alertView:(UIAlertView *)alert clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex == 0){
//initiate import
[self handleImportURL:_importURL];
}
else{
//don't initiate import
}
}

Here is the chunk of code I've added to my didFinishLaunchingWithOptions method. I've gotten almost everything working. The web views work now when selecting a row and the navigation bar is there and seemingly works as it should. The only trouble I'm having now is getting the tab bar to show up. Here is the chunk of code I'm currently using.
UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (notification)
{
ActionAlertsViewController *actionAlerts = [[ActionAlertsViewController alloc] initWithStyle:UITableViewStylePlain];
WebViewController *wvc = [[WebViewController alloc]init];
[actionAlerts setWebViewController:wvc];
KFBNavControllerViewController *navController7 = [[KFBNavControllerViewController alloc] initWithRootViewController:actionAlerts];
[self.window.rootViewController presentViewController:navController7 animated:NO completion:nil];
}
You could post a notification yourself when you receive a remote notification and by registering the viewcontroller to this notification, you could open a particular viewController once notification is received.
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo{
[[NSNotificationCenter defaultCenter] postNotificationName:#"pushNotification" object:nil userInfo:userInfo];
}
In your FirstViewController.m register for listening to this notification.
-(void)viewDidLoad{
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(pushNotificationReceived) name:#"pushNotification" object:nil];
}
Inside the method you could open particular viewController
-(void)pushNotificationReceived{
[self presentViewController:self.secondViewController animated:YES completion:nil];
}
Finally un-register current viewController from notification in dealloc method
-(void)dealloc{
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
If the app is opened from a notification, either of the two methods from your app delegate will be called
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
OR
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
In case of the latter, the launchOptions will let you know if the app was launched due to a remote notification or some other reason (see Launch Option Keys here)
Put in a check in these methods so that the specific viewcontroller will be opened if the app is launched from a notification.
You can do some thing like this
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
// If application is launched due to notification,present another view controller.
UILocalNotification *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
if (notification)
{
NotificationViewController *viewController = [[NotificationViewController alloc]initWithNibName:NSStringFromClass([NotificationViewController class]) bundle:nil];
[self.window.rootViewController presentModalViewController:viewController animated:NO];
[viewController release];
}
return YES;
}
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
NotificationViewController *viewController = [[NotificationViewController alloc]initWithNibName:NSStringFromClass([NotificationViewController class]) bundle:nil];
[self.window.rootViewController presentModalViewController:viewController animated:NO];
[viewController release];
}
I am following a tutorial doing a Game Center Turn-based match, tic-tac-toe game, and my view controller is not loaded. It works when i use the source code but not with the code i have typed myself, from the book. I have checked and cant find any difference.
I do get into Game Center and when i click on "Play your turn" it loads the initial screen with the button "Begin game" and not, as the original code, the "tictactoeGameViewController" as it suppose to.
I would very much appreciate if someone could help me out here :-)
Here is my code:
#import "ViewController.h"
#import "tictactoeGameViewController.h"
#interface ViewController ()
#end
#implementation ViewController

}

I did find the solution:
The ViewController must be RootViewController so i changed:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
self.viewController = [[[ViewController alloc] initWithNibName:#"ViewController" bundle:nil] autorelease];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
To:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
ViewController *controller = [[ViewController alloc] init];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:controller];
self.window.rootViewController = self.navigationController;
[self.window makeKeyAndVisible];
return YES;
}
The App I'm trying to do has a tabbar controller.
When the App starts, I'm getting the user location in the AppDelegate and when I've got the accuracy I need the AppDelegate sends an NSNotification to my App's starting page (index 0 of the tab bar controller).
Upon receiving the notification, this view tries to send an email with the user coordinates and other data, but as soon as the MFMailComposeViewController is presented I get the following error:
Warning: Attempt to present <MFMailComposeViewController: 0x98a0270> on <UITabBarController: 0x988c630> whose view is not in the window hierarchy!
What am I missing?
Thanks.
EDIT: adding some code...
This is what I've got in my AppDelegate.m:
- (void) locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
NSUserDefaults *phoneNumbers = [NSUserDefaults standardUserDefaults];
NSDate *eventDate = newLocation.timestamp;
NSTimeInterval howRecent = [eventDate timeIntervalSinceNow];
if (abs(howRecent) < 10.0) {
[self locationUpdate:newLocation];
smsLoc = newLocation;
if ([[phoneNumbers objectForKey:#"sendSMS"] isEqualToString:#"yes"]) {
[[NSNotificationCenter defaultCenter] postNotificationName:#"sendSMS" object:nil];
} else if ([[phoneNumbers objectForKey:#"sendEmail"] isEqualToString:#"yes"]) {
[[NSNotificationCenter defaultCenter] postNotificationName:#"sendEmail" object:nil];
}
}
}
Then, in my first view controller I have:
- (void)viewDidLoad
{
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(sendSMS:) name:#"sendSMS" object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(sendEmail:) name:#"sendEmail" object:nil];
}
And at the end, the selector for "sendSMS" (the other is pretty similar):
- (void)sendSMS: (NSNotification *)notification {
NSUserDefaults *phoneNumbers = [NSUserDefaults standardUserDefaults];
if ([phoneNumbers objectForKey:#"first"] || [phoneNumbers objectForKey:#"second"]) {
MFMessageComposeViewController *controller = [[MFMessageComposeViewController alloc] init];
if ([MFMessageComposeViewController canSendText]) {
AppDelegate *deleg = (AppDelegate *)[[UIApplication sharedApplication] delegate];
controller.body = [NSString stringWithFormat:#"some message with coordinates %.4f - %.4f", [deleg currentLocation].coordinate.latitude, [deleg currentLocation].coordinate.longitude];
controller.recipients = [NSArray arrayWithObjects:[phoneNumbers objectForKey:#"first"], [phoneNumbers objectForKey:#"second"], nil];
controller.messageComposeDelegate = self;
[self presentModalViewController:controller animated:YES];
}
}
}
}
Second edit: adding some more code.
UITabBarController *tabBarController = [[UITabBarController alloc] init];
tabBarController.delegate = self;
tabBarController.selectedIndex = 0;
[[tabBarController.tabBar.items objectAtIndex:0] setTitle:NSLocalizedString(#"Home", nil)];
[[tabBarController.tabBar.items objectAtIndex:1] setTitle:NSLocalizedString(#"Requests", nil)];
[[tabBarController.tabBar.items objectAtIndex:2] setTitle:NSLocalizedString(#"Account", nil)];
[[tabBarController.tabBar.items objectAtIndex:3] setTitle:NSLocalizedString(#"Settings", nil)];
//some other controls from DB
[[tabBarController.tabBar.items objectAtIndex:1] setBadgeValue:[NSString stringWithFormat:#"%d",number]];
The tabbarController has been made via IB, but I've added the code above in my AppDelegate because I need to localize the tab bar items and to add a badge to one of them.
Am I doing something wrong here?
I'm not sure if you have solve this issue. The error message means the viewcontroller you use to present another modal viewcontroller is not visible on the window. This can happen for e.g:
[VC1 presentModalViewController:VC2];
// Error here, since VC1 is no longer visible on the window
[VC1 presentModalViewController:VC3];
If your issue is like above, you can fix it like:
if (self.modalViewController != nil) {
[self.modalViewController presentModalViewController:VC3 animated:YES];
} else {
[self.tabBarController presentModalViewController:VC3 animated:YES];
}
If that doesn't fix your issue, maybe you can try to present using self.tabBarController instead of self. Again just suggestion, not sure if it works though.
Using this may help someone: [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:picker animated:NO completion:nil];
Since modalViewController and presentModalViewController are deprecated, the following is what works for me:
presentingVC = [[UIApplication sharedApplication] keyWindow].rootViewController;
if (presentingVC.presentedViewController) {
[presentingVC.presentedViewController presentViewController:VC3 animated:YES completion:nil];
} else {
[presentingVC presentViewController:VC3 animated:YES completion:nil];
}
You can follow this pattern
[VC1 presentModalViewController:VC2];
//
[**VC2** presentModalViewController:VC3];
