I am using the great source code called GSDropboxDemoApp which nicely integrate the Dropbox in the application. However, after linked to the app to Dropbox, it gives error in loading folder contents. Below are the codes
I have already edited the info.plist
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
#warning Potentially incomplete method implementation. Fill in your Dropbox credentials!
#warning NB: you must also update the URL scheme listed under the CFBundleURLTypes key in GSDropboxDemoApp-Info.plist
NSString *dropboxAppKey = #"sxxxxxxxxxx";
NSString *dropboxAppSecret = #"cxxxxxxxxx";
NSString *dropboxRoot = #"kDBRootAppFolder"; // either kDBRootAppFolder or kDBRootDropbox
DBSession* dbSession = [[DBSession alloc] initWithAppKey:dropboxAppKey
appSecret:dropboxAppSecret
root:dropboxRoot];
[DBSession setSharedSession:dbSession];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.viewController = [[GSViewController alloc] initWithNibName:#"GSViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
if ([[DBSession sharedSession] handleOpenURL:url]) {
if ([[DBSession sharedSession] isLinked]) {
NSLog(#"App linked to Dropbox successfully");
} else {
NSLog(#"App not linked to Dropbox!");
}
return YES;
}
return NO;
}
Error Message
GSDropboxDemoApp[4674:907] [WARNING] DropboxSDK: error making request to /1/metadata/kDBRootAppFolder - (400) Expected a root of either 'dropbox' or 'sandbox', got 'kDBRootAppFolder'
You should be using a constant, like so:
NSString *dropboxRoot = kDBRootAppFolder; // either kDBRootAppFolder or kDBRootDropbox
Constants are used so that you don't need to worry about the actual value itself.
And for those of us (in the future that stumble across this question) getting the same error using ruby motion, it needs to be:
dropboxRoot = KDBRootAppFolder # Capital K

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.
Hello everyone I am trying to get a location update when my app is in background. But the code below does not seems to work. The IF statement is never true. I have also set the necessary keys in the info.plist files. I am running the code in iphone 3GS and ipad 3.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customizatio-n after application launch.
id locationValue = [launchOptions objectForKey:UIApplicationLaunchOptionsLocationKey];
if (locationValue)
{
// create a new manager and start checking for sig changes
locManager = [[CLLocationManager alloc] init];
locManager.delegate = self;
[locManager startMonitoringSignificantLocationChanges];
return YES;
}
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 successfully installed heatma.ps SDK (https://heatma.ps) in my iPhone application. It tracks all the touches and gestures, but I can't view a heatmap when I shake my device. Any idea why? There is no log, it just doesn't show up.
This is how I setup my heatmaps object.
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//...
heatmaps = [[Heatmaps alloc] init];
heatmaps.showDebug = YES;
[heatmaps start];
//...
}
To see heatmaps you need to set showMenu property of heatmaps object to YES
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//...
heatmaps = [[Heatmaps alloc] init];
heatmaps.showDebug = YES;
heatmaps.showMenu = YES;
[heatmaps start];
//...
}
Watch the following screencast: "Viewing heatmaps"
I'm trying to open a .pdf-file in my app. I adapted the Info.plist so a .pdf can be opened in my application.
I use the following code:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
thePDFurl = (NSURL *)[launchOptions valueForKey:UIApplicationLaunchOptionsURLKey];
return YES;
}
In an other class, where my appDelegate (containing that didFinishLaunchingWithOptions), I've got the line:
appDel = [[UIApplication sharedApplication]delegate];
[theLabel setText:[NSString stringWithFormat:#"%#", appDel.thePDFurl]];
Somehow, theLabel always shows (null). What am I missing?
I may be misunderstanding what you're trying to do. If so, ignore.
If you want the user to be able to "Open with..." a PDF using your app, you can implement
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
E.g.
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
NSLog(#"Open URL:\t%#\n"
"From source:\t%#\n"
"With annotation:%#",
url, sourceApplication, annotation);
NSString *filepath = [url path];
//...
return YES;
}
I'm pretty sure this works for both launching the app and calling it (i.e. if it's already in the background).
You may retain the pdfurl variable and also get the absolute string value from NSURL using the absoluteString method.
[theLabel setText:[NSString stringWithFormat:#"%#", [appDel.thePDFurl absoluteString]]]
I guess you were all right. It just so happened the view got loaded before the method applicationDidFinishLaunching was finished. Thanks all...
When you are calling within application:didFinishLaunchingWithOptions: ,
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
[viewController view] was implicitly called and there was no appDel.thePDFurl assigned yet.
