使用示例应用程序。在我的应用中使用示例应用的SignInViewController不起作用。我已将大部分示例应用复制到我的AppDelelgate。
我已经修改了SignInViewController，因为我正在浏览它以登录。
当我使用用户getDetails时，我的委托代码（startPasswordAuthentication）可以正常工作。但是当我使用signInPressed时：没有任何反应。
这是我的AppDelegate：
#import "AppDelegate.h"
#import "AWSConstants.h"
#import "PeepVC.h"
#import "WelcomeViewController.h"
//#import <GoogleMaps/GoogleMaps.h>
@import GoogleMapsBase;
@import GooglePlaces;
@interface AppDelegate ()
@property (nonatomic,strong) AWSTaskCompletionSource<NSNumber *>* rememberDeviceCompletionSource;
@end
@implementation AppDelegate
{
GMSPlacesClient *_placesClient;
UIBackgroundTaskIdentifier bgTask;
}
@synthesize cognitoId,locationManager,awsUser,awsPW;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
// new pool info for users
//setup service config
AWSServiceConfiguration *serviceConfiguration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1 credentialsProvider:nil];
AWSCognitoIdentityUserPoolConfiguration *configuration = [[AWSCognitoIdentityUserPoolConfiguration alloc] initWithClientId:@"--omitted--"
clientSecret:@"--omitted--"
poolId:@"--omitted--"];
[AWSCognitoIdentityUserPool registerCognitoIdentityUserPoolWithConfiguration:serviceConfiguration userPoolConfiguration:configuration forKey:@"UserPool"];
AWSCognitoIdentityUserPool *pool = [AWSCognitoIdentityUserPool CognitoIdentityUserPoolForKey:@"UserPool"];
pool.delegate = self;
NSLog(@"Pool:%@",pool);
NSLog(@"AWS configuration:%@",configuration);
NSLog(@"AWS service configuration:%@",serviceConfiguration);
NSLog(@"AWS Cognito Identity Pool:%@",pool.userPoolConfiguration);
NSString *deviceInfo = [NSString stringWithFormat:@"Name:%@ Model:%@ (%@:%@)", [UIDevice currentDevice].name, [UIDevice currentDevice].model, [UIDevice currentDevice].systemName, [UIDevice currentDevice].systemVersion];
NSLog(@"Device Info:%@",deviceInfo);
[GMSPlacesClient provideAPIKey:@"--omitted--"];
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(setupMainView) name:@"registerForNotifications" object:nil];
}
if (nil == locationManager)
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
self.venueDataModel = [[NSMutableDictionary alloc] init];
self.venueDataModelIndices = [[NSMutableDictionary alloc] init];
self.venueUserDict = [[NSMutableDictionary alloc] init];
//Set signedUp to Yes or something else in order to skip the tutorial
if (![[NSUserDefaults standardUserDefaults] objectForKey:@"accountStatus"]) {
[self initializeTutorial];
} else {
[self setupMainView];
}
self.storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
return YES;
}
这是我的SignInViewController：
#import "SignInViewController.h"
@interface SignInViewController ()

@property (nonatomic, strong) AWSCognitoIdentityUserPool * pool;
@end
@implementation SignInViewController
- (void) viewWillAppear:(BOOL)animated {
self.password.text = nil;
self.username.text = self.usernameText;
[self.navigationController setNavigationBarHidden:YES];
self.pool = [AWSCognitoIdentityUserPool CognitoIdentityUserPoolForKey:@"UserPool"];
NSLog(@"Pool:%@",self.pool);
if(!self.user)
NSLog(@"//SignInViewController:!self.user");
self.user = [self.pool currentUser];
[self refresh];
}
-(void) refresh {
NSLog(@"//SignInViewController:refresh");
[[self.user getDetails] continueWithSuccessBlock:^id _Nullable(AWSTask<AWSCognitoIdentityUserGetDetailsResponse *> * _Nonnull task) {
dispatch_async(dispatch_get_main_queue(), ^{
self.response = task.result;
self.title = self.user.username;
NSLog(@"//UserDetailTableViewController:reloadData");
//[self.tableView reloadData];
});
return nil;
}];
}
- (IBAction)signInPressed:(id)sender {
NSLog(@"SignInPressed:%@",self.username.text);
self.passwordAuthenticationCompletion.result = [[AWSCognitoIdentityPasswordAuthenticationDetails alloc] initWithUsername:self.username.text password:self.password.text];
}
-(void) getPasswordAuthenticationDetails: (AWSCognitoIdentityPasswordAuthenticationInput *) authenticationInput passwordAuthenticationCompletionSource: (AWSTaskCompletionSource<AWSCognitoIdentityPasswordAuthenticationDetails *> *) passwordAuthenticationCompletionSource {
NSLog(@"getPasswordAuthenticationDetails:");
self.passwordAuthenticationCompletion = passwordAuthenticationCompletionSource;
NSLog(@"self.passwordAuthenticationCompletion:%@",passwordAuthenticationCompletionSource);
dispatch_async(dispatch_get_main_queue(), ^{
if(!self.usernameText)
self.usernameText = authenticationInput.lastKnownUsername;
NSLog(@"self.usernameText:%@",self.usernameText);
});
}
-(void) didCompletePasswordAuthenticationStepWithError:(NSError*) error {
NSLog(@"didCompletePasswordAuthenticationStepWithError:");
dispatch_async(dispatch_get_main_queue(), ^{
if(error){
[[[UIAlertView alloc] initWithTitle:error.userInfo[@"__type"]
message:error.userInfo[@"message"]

在演示中，一旦调用了“signInPressed”，您就会看到下面的日志条目，以及更多的服务器响应。

我必须遗漏一些细节，但我无法弄明白。提前感谢您的指导。
