我想让我的应用程序将它创建的文档保存到iCloud Drive,但我很难跟上Apple写的内容.这是我到目前为止所做的,但我不确定从哪里开始.

UPDATE2

我的代码中有以下内容手动将文档保存到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]; …
