Question

所以我downloaded the attached project并将代码复制到我的项目。这就是我所做的。

我用正确的值替换了以下内容。我在亚马逊认知中创建了一个USERPOOL来获取这些值。

NSString *const CognitoIdentityUserPoolId = @"XXX";
NSString *const CognitoIdentityUserPoolAppClientId = @"XXX";
NSString *const CognitoIdentityUserPoolAppClientSecret = @"XXX";

我的问题是，一旦didFinishLaunchingWithOptions被执行，它将启动委托方法-(id<AWSCognitoIdentityPasswordAuthentication>) startPasswordAuthentication。但是，在我的情况下，它不能解决这个问题吗？

AppDelegate.h看起来像这样

#import <UIKit/UIKit.h>
#import <CoreData/CoreData.h>
#import "AWSCognitoIdentityProvider.h"

@interface AppDelegate : UIResponder <UIApplicationDelegate,AWSCognitoIdentityInteractiveAuthenticationDelegate>

@property (strong, nonatomic) UIWindow *window;

@property (readonly, strong, nonatomic) NSManagedObjectContext *managedObjectContext;
@property (readonly, strong, nonatomic) NSManagedObjectModel *managedObjectModel;
@property (readonly, strong, nonatomic) NSPersistentStoreCoordinator *persistentStoreCoordinator;
- (void)saveContext;
- (NSURL *)applicationDocumentsDirectory;
@end

AppDelegate.m看起来像这样

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

//setup logging
    [AWSLogger defaultLogger].logLevel = AWSLogLevelVerbose;

    //setup service config
    AWSServiceConfiguration *serviceConfiguration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1 credentialsProvider:nil];

    if([@"YOUR_USER_POOL_ID" isEqualToString:CognitoIdentityUserPoolId]){
        [[[UIAlertView alloc] initWithTitle:@"Invalid Configuration"
                                    message:@"Please configure user pool constants in Constants.m"
                                   delegate:nil
                          cancelButtonTitle:nil
                          otherButtonTitles:@"Ok", nil] show];
    }

    //create a pool
    AWSCognitoIdentityUserPoolConfiguration *configuration = [[AWSCognitoIdentityUserPoolConfiguration alloc] initWithClientId:CognitoIdentityUserPoolAppClientId  clientSecret:CognitoIdentityUserPoolAppClientSecret poolId:CognitoIdentityUserPoolId];

    [AWSCognitoIdentityUserPool registerCognitoIdentityUserPoolWithConfiguration:serviceConfiguration userPoolConfiguration:configuration forKey:@"UserPool"];

    AWSCognitoIdentityUserPool *pool = [AWSCognitoIdentityUserPool CognitoIdentityUserPoolForKey:@"UserPool"];

    //self.storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

    pool.delegate = self;

    return YES;


}

-(id<AWSCognitoIdentityPasswordAuthentication>) startPasswordAuthentication{
    NSLog(@"Came into this method");
    return _signInViewController;
}

通过禁用情节提要，您已删除调用以获取用户的会话，因此不会调用身份验证委托方法。在这段代码中放置一些这样的代码会得到一个会话并触发auth流程：

[[pool currentUser] getSession];
