An easy way to get Social Networks authenticating by OAuth 2.0 on Objective-C via UIWebView
Create NSObject class import "OAuthConfigurator.h" and implement OAuthConfigurator protocol:
@implementation Configurator
#pragma mark OAuthConfigurator methods
- (NSURL *)redirectURI
{
return [NSURL URLWithString:@"http://localhost"];
}
- (NSString *)facebookApplicationID
{
return @"APPLICATION_ID";
}
- (NSString *)facebookScope
{
return @"SCOPE";
}
...
Create OAuthController and set to constructor Social OAuth object from SocialOAuthFactory:
- (void)presentOAuthWithOAuthType:(OAuthType)type
{
SocialOAuthFactory *socialOAuthFactory = [[SocialOAuthFactory alloc] initWithConfigurator:[Configurator new]];
OAuthController *oauthController = [[OAuthController alloc] initWithSocialOAuth:[socialOAuthFactory OAuthByType:type]];
oauthController.completionBlock = ^(NSDictionary *response, NSString *errorString, __weak UIViewController *weakOAuthController)
{
if(!errorString)
{
// create OAuthCredential from response and save to Keychain or something else
}
else
{
[[[UIAlertView alloc] initWithTitle:NSLocalizedString(@"Authorization Error", nil) message:errorString delegate:nil cancelButtonTitle:NSLocalizedString(@"OK", nil) otherButtonTitles:nil] show];
}
[weakOAuthController.navigationController dismissViewControllerAnimated:YES completion:nil];
};
oauthController.onCancelButtonTap = ^(__weak UIViewController *weakOAuthController)
{
[weakOAuthController.navigationController dismissViewControllerAnimated:YES completion:nil];
};
[self presentViewController:[[UINavigationController alloc] initWithRootViewController:oauthController] animated:YES completion:nil];
}
Create OAuthCredential from completion block response via OAuthManager:
OAuthCredential *credential = [[OAuthManager manager] credentialByResponse:response];OAuthCredential supporting NSCoding protocol, you can save OAuthCredential object to Keychain, NSUserDefault and etc.
Create Social Network class subclass of SocialOAuth and override constructor:
@implementation YandexOAuth
#pragma mark Interface methods
+ (instancetype)OAuth
{
return [[YandexOAuth alloc] initWithBaseURL:@"https://oauth.yandex.ru/" authPath:@"authorize" clientID:@"CLIEND_ID" clientSecret:@"CLIENT_SECRET" responseType:@"token" redirectURI:[NSURL URLWithString:@"http://localhost"] scope:@"SCOPE"];
}Also you can create class subclass of OAuthAppearance:
@implementation YanexAppearance
#pragma mark NSObject methods
- (instancetype)init
{
self = [super init];
if(self)
{
self.title = NSLocalizedString(@"Яндекс", nil);
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:self.title];
[attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, 1)];
[attributedString addAttribute:NSFontAttributeName value:[UIFont systemFontOfSize:20.0f] range:NSMakeRange(0, self.title.length)];
self.attributedString = attributedString;
self.tintColor = [UIColor blackColor];
self.mainColor = [UIColor colorWithRed:1.00 green:1.00 blue:1.00 alpha:1.00];
self.backgroundColor = [UIColor colorWithRed:0.96 green:0.96 blue:0.95 alpha:1.00];
self.statusBarStyle = UIStatusBarStyleDefault;
}
return self;
}And set to Social OAuth (override main constructor):
- (instancetype)initWithBaseURL:(NSString *)baseURL authPath:(NSString *)authPath clientID:(NSString *)clientID clientSecret:(NSString *)clientSecret responseType:(NSString *)responseType redirectURI:(NSURL *)redirectURI scope:(NSString *)scope
{
self = [super initWithBaseURL:baseURL authPath:authPath clientID:clientID clientSecret:clientSecret responseType:responseType redirectURI:redirectURI scope:scope];
if(self)
{
self.appearance = [YanexAppearance appearance];
}
return self;
}Create YanexAppearance and set to OAuthController:
OAuthController *oauthController = [[OAuthController alloc] initWithSocialOAuth:[YanexAppearance OAuth]];
oauthController.onCancelButtonTap = ^(__weak UIViewController *weakOAuthController)
{
// dismiss
};
oauthController.completionBlock = ^(CATOAuthCredential *credential, NSString *errorString, __weak UIViewController *weakOAuthController)
{
// dismiss and process credential (save to user defaults or something else)
};
[self presentViewController:[[UINavigationController alloc] initWithRootViewController:oauthController] animated:YES completion:nil];
- Support
SFSafariViewController. But some social networks don’t support callback likemyapp://callback; - Support OAuth 1.0 for
Twitterand etc; - Tests, correct serialize response data;
- Support
TV_OS; - Renew
Access token; - More social networks : ) ;
- Any ideas ?
