I am new to react native and just started learning it. I have downloaded some sample apps from github and was using them in my learning process.
I am a true beginner..
I have setup my mac pro with react native and in this case I have downloaded an app called movieapp. I have installed it and when I run it in the simulator it works perfect.
Note: I have a paid developer account with apple for Xcode and I am running version 8.3.1 (8E1000a)
I have changed the app for my signing info.
When I run build this app from Xcode to my iPhone 7+ I get this screen
iPhone 7+ screen shot
Here is a screen shot of the Terminal window that pops up when this is built in Xcode.
[Mac Terminal Screen][2]
Could someone please point me in the correct direction to solve this issue?

I have a dead line and dont know what to do with that. IM tryin to use react-native-fbsdk with firebase on and wanted to link the sdk to ios. Everything is good but this function:
[[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
// Add any custom logic here.
return YES;
Im trying to put this here:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
NSURL *jsCodeLocation;
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:#"index.ios" fallbackResource:nil];
RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
moduleName:#"tzawajna"
initialProperties:nil
launchOptions:launchOptions];
rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1];
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
UIViewController *rootViewController = [UIViewController new];
rootViewController.view = rootView;
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
return YES;
[[FBSDKApplicationDelegate sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
// Add any custom logic here.
return YES;
}
And Its giving an error of
use of undeclared identifier FBSDKApplicationDelegate
What should I do.
Thanks
Check whether In your application:openURL:options implementation ( or for any other method in the file), the parameter is named app and not application.
You can either change the parameter name in the method signature to application:
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
options:(NSDictionary<UIApplicationOpenURLOptionsKey,id> *)options
This error can be caused because of the difference in the parameter of such method.
I have TestFlight SDK integrated into my iOS app. In iOS 6.1.2, sometimes the app crashes for the first-time app launch at TestFlight's -takeOff: method.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions: (NSDictionary *)launchOptions
{
#ifdef TESTING
[TestFlight takeOff:#"MY_TESTFLIGHT_TEAM_TOKEN"];
[TestFlight setDeviceIdentifier:[[UIDevice currentDevice] uniqueIdentifier]];
#endif
// Override point for customization after application launch.
ProductListViewController *products=[[ProductListViewController alloc] initWithNibName:#"ProductListViewController" bundle:nil];
UINavigationController *navigationController=[[UINavigationController alloc] initWithRootViewController:products];
[products release];
navigationController.toolbarHidden = YES;
navigationController.navigationBarHidden = YES;
self.rootViewController = navigationController;
[self.window setRootViewController:rootViewController];
[navigationController release];
[self.window makeKeyAndVisible];
return YES;
}
Any help is greatly appreciated.
Thanks
This is a bug in the Testflight SDK. They ask you to update to the latest beta version.
See iOS exception EXC_GUARD
Could it be that you've forgotten to include the TestFlight SDK folder properly?
I have implemented iOS 6 API for state saving, it works - after I quit the app and launch back in for some milliseconds the restored view controller fly in, but then it's replaced by the main view controller I display at launch.
I'm setting every time the app launch the root view of the main window, so this must be the issue.
Here is my code:
- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self commonInitializationLaunching:launchOptions];
return YES;
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
[self commonInitializationLaunching:launchOptions];
return YES;
}
- (void)commonInitializationLaunching:(NSDictionary *)launchOptions
{
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
static NSString *const kKeychainItemName = #"OAuthGoogleReader";
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.navController = [[UINavigationController alloc] initWithRootViewController:self.viewController];
GTMOAuth2Authentication *auth;
auth = [GTMOAuth2ViewControllerTouch authForGoogleFromKeychainForName:kKeychainItemName
clientID:kClientID
clientSecret:kClientSecret];
self.window.rootViewController = self.navController;
[self.window makeKeyAndVisible];
BOOL isSignedIn = [auth canAuthorize];
if (isSignedIn) {
NSLog(#"Signed");
}else{
NSString *scope = #"https://www.google.com/reader/api/";
GTMOAuth2ViewControllerTouch *viewController;
viewController = [[GTMOAuth2ViewControllerTouch alloc] initWithScope:scope
clientID:kClientID
clientSecret:kClientSecret
keychainItemName:kKeychainItemName
delegate:self
finishedSelector:#selector(viewController:finishedWithAuth:error:)];
[self.navController pushViewController:viewController animated:YES];
// self.window.rootViewController = viewController;
}
});
}
You can see that in -(void)commonInitializationLaunching:(NSDictionary *)launchOptions
I'm setting my window's root view. I don't know what to put in there. Perhaps check if there is saved state and then load this method? But how?
Thanks!
Here is what I've tried following Rob's advice:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
if (!self.isRestored) {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
}
[self commonInitializationLaunching:launchOptions];
[self.window makeKeyAndVisible];
return YES;
}
with nothing in willFinishLaunching...
I also removed by window code from my commonInitializationLaunching method.
Storyboards will do most of the heavy lifting for you, such as restoring the window. Using code, however, will not restore the window. You will need to hold on to your root view controller using the encoder. Your code will look something like this:
NSString * const AppDelegateRootVCKey = #"AppDelegateRootVCKey";
- (void)application:(UIApplication *)application willEncodeRestorableStateWithCoder:(NSCoder *)coder {
[coder encodeObject:self.window.rootViewController forKey:AppDelegateRootVCKey];
}
- (void)application:(UIApplication *)application didDecodeRestorableStateWithCoder:(NSCoder *)coder {
// Grabs the preserved root view controller.
UIViewController * vc = [coder decodeObjectForKey:AppDelegateRootVCKey];
if (vc) {
UIWindow * window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
window.rootViewController = vc;
window.restorationIdentifier = NSStringFromClass([window class]);
// The green color is just to make it obvious if our view didn't load properly.
// It can be removed when you are finished debugging.
window.backgroundColor = [UIColor greenColor];
self.window = window;
}
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
if (!self.window) {
UIWindow *window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// The blue color is just to make it obvious if our view didn't load properly.
// It can be removed when you are finished debugging.
window.backgroundColor = [UIColor blueColor];
UIViewController *root = // However you create your root.
window.rootViewController = root;
window.restorationIdentifier = NSStringFromClass([window class]);
self.window = window;
}
[self commonInitializationLaunching:launchOptions];
[self.window makeKeyAndVisible];
return YES;
}
Another gotcha to watch out for is to make sure that your UINavigationControllers and UITabBarControllers have restoration identifiers.
State restoration is generally integrated with storyboards. If you're using a storyboard, you should not be creating your own window, view controllers, etc. You should let the storyboard do this for you. What's happening is that the storyboard is doing all the state restoration, and then you're creating a new window and laying it on top of all that. If that's the case, you're probably creating two copies of your UI on every launch. You're just not noticing it.
If you are constructing your entire interface in code (not a recommended approach, but it does work), then you need to determine whether state restoration happened before creating your UI. This is fairly simple:
In your commonInitializationLaunching:, initialize only non-UI elements (things that wouldn't ever be in state-preservation). This is the place to handle things that the UI elements might rely on during state restoration. You don't have any of these in your current code.
In application:didDecodeRestorableState:, set an app delegate ivar to indicate that state was restored.
In application:didFinishLaunchingWithOptions:, after running commonInitializationLaunching:, check your ivar. If state wasn't restored, create a UI.
Do remember that the commonInitializationLaunching: pattern only exists for backward compatibility with iOS 5. If you don't need that, then just put non-UI in willFinish and UI in didFinish (if state wasn't restored).
I am using Apple's newest Xcode for MacOS 10.7(Lion). I am trying to make a iPhone application. I'm new to the language and decided to load up apples guides. 'Your first iOS application'. It was good, taught me a few things but Its not working. I get Expected Getter Method Not Found On Object Of Type 'TestAppDelegate *'
How do i Fix this?
Heres the code:
TestAppDelegate.m
#import "TestAppDelegate.h"
#import "MyViewController.h"
#implementation TestAppDelegate
#synthesize window=_window;
#synthesize myViewController=_myViewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
MyViewController *aViewController = [[MyViewController alloc] initWithNibName:#"MyViewController" bundle:nil];
self.myViewController = aViewController;
// Or, instead of the line above:
// [self setMyViewController:aViewController];
[aViewController release];
self.window.rootViewController = self.MyViewController;
[self.window makeKeyAndVisible];
return YES;
}
/* Other methods omitted from the listing. */
- (void)dealloc {
[_myViewController release];
[_window release];
[super dealloc];
}
#end
The line:
self.window.rootViewController = self.MyViewController;
Has the problem
objective-c is case-sensitive. You wrote an upper-case M instead of lower-case.
self.window.rootViewController = self.myViewController;
Your window doesn't exist yet (at least from what I can see in your code). Add this before the line causing the SIGABRT:
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
Using the Pre Release Xcode 3.2.3 I get this as a Startup Project
(source: balexandre.com)
What should I chose / do to great a project that can have both iPad and iPhone as a target (not showing the iPhone App on iPad but a real iPad View)?
Thank you.
To avoid problems:
iPhone OS 3.1.3 is the latest release on iPhone
iPhone OS 3.2 is the latest release on iPad
My question does not infringe any agreements that me and Apple are bound to, as my question is regarding those already public Releases.
I just stated that on my Operating System I'm running the Xcode 3.2.3, that is all.
just found out a simple way:

Then, if you want to switch to XIB files per device, let's say, the MainView for iPhone is A and the MainView for iPad is B, in your AppDelegate you add this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// The default have the line below, let us comment it
//MainViewController *aController = [[MainViewController alloc] initWithNibName:#"MainView" bundle:nil];
// Our main controller
MainViewController *aController = nil;
// Is this OS 3.2.0+ ?
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 30200
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
// It's an iPad, let's set the MainView to our MainView-iPad
aController = [[MainViewController alloc]
initWithNibName:#"MainView-iPad" bundle:nil];
else
// This is a 3.2.0+ but not an iPad (for future, when iPhone runs with same OS than iPad)
aController = [[MainViewController alloc]
initWithNibName:#"MainView" bundle:nil];
#else
// It's an iPhone (OS < 3.2.0)
aController = [[MainViewController alloc] initWithNibName:#"MainView" bundle:nil];
#endif
// Let's continue our default code
self.mainViewController = aController;
[aController release];
mainViewController.view.frame = [UIScreen mainScreen].applicationFrame;
[window addSubview:[mainViewController view]];
[window makeKeyAndVisible];
return YES;
}
You can choose the Application Type as "Universal" .
