I want to have my app save the documents it creates to iCloud Drive, but I am having a hard time following along with what Apple has written. Here is what I have so far, but I'm not for sure where to go from here.
UPDATE2
I have the following in my code to manually save a document to iCloud Drive:
- (void)initializeiCloudAccessWithCompletion:(void (^)(BOOL available)) completion {
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
self.ubiquityURL = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];
if (self.ubiquityURL != nil) {
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"iCloud available at: %@", self.ubiquityURL);
completion(TRUE);
});
}
else {
dispatch_async(dispatch_get_main_queue(), ^{
NSLog(@"iCloud not available");
completion(FALSE);
});
}
});
}
if (buttonIndex == 4) {
[self initializeiCloudAccessWithCompletion:^(BOOL available) {
_iCloudAvailable = available;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfPath = [documentsDirectory stringByAppendingPathComponent:selectedCountry];
NSURL* url = [NSURL fileURLWithPath: pdfPath];
[self.manager setUbiquitous:YES itemAtURL:url destinationURL:self.ubiquityURL error:nil];
}];
}
I have the entitlements set up for the App ID and in Xcode itself. I click the button to save to iCloud Drive, and no errors pop up, the app doesn't crash, but nothing shows up on my Mac in iCloud Drive. The app is running on my iPhone 6 Plus via Test Flight while using iOS 8.1.1.
If I run it on Simulator (I know that it won't work due to iCloud Drive not working with simulator), I get the crash error: 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[3]'
