下面是我的代码,我用来从Google帐户获取数据,我想在其他视图中使用电子邮件地址作为登录ID。如何将从json检索的数据从一个视图传递到另一个视图?
此代码位于我的FirstViewController
中,我想在另一个视图中使用电子邮件。
请帮助:)
- (void)finishedWithAuth:(GTMOAuth2Authentication *)auth
error:(NSError *)error {
if (error) {
return;
}
NSString *accessTocken = [auth valueForKey:@"accessToken"]; // access tocken pass in .pch file
NSLog(@"%@",accessTocken);
NSString *str=[NSString stringWithFormat:@"https://www.googleapis.com/oauth2/v1/userinfo?access_token=%@",accessTocken];
NSString *escapedUrl = [str stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:@"%@",escapedUrl]];
NSString *jsonData = [[NSString alloc] initWithContentsOfURL:url usedEncoding:nil error:nil];
NSDictionary *jsonDictionary = [NSJSONSerialization JSONObjectWithData:[jsonData dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&error];
NSString *userId=[jsonDictionary objectForKey:@"email"];
NSLog(@" user data %@",jsonData);
NSLog(@"Received Access Token:%@",auth);
NSLog(@"email id : %@ ",userId);
GTLServicePlus* plusService = [[GTLServicePlus alloc] init];
plusService.retryEnabled = YES;
[plusService setAuthorizer:auth];
GTLQueryPlus *query = [GTLQueryPlus queryForPeopleGetWithUserId:userId];
[plusService executeQuery:query completionHandler:^(GTLServiceTicket *ticket,GTLPlusPerson *person,NSError *error) {
if (error) {
GTMLoggerError(@"Error: %@", error);
} else {
// Retrieve the display name and "about me" text
// [person retain];
NSString *description = [NSString stringWithFormat:
@"%@\n%@", person.displayName,
person.aboutMe];
GTLPlusPersonImage *image =person.image;
NSString *strimag=[image valueForKey:@"url"];
// [self setImageFromURL:[NSURL URLWithString:strimag]];
NSData *receivedData = [NSData dataWithContentsOfURL:[NSURL URLWithString:strimag]];
UIImage *img = [[UIImage alloc] initWithData:receivedData ];
receivedData=UIImageJPEGRepresentation(img,50);
NSLog(@"description %@",description);
}
}];
if ([GPPSignIn sharedInstance] == true) {
[self performSegueWithIdentifier:@"pass" sender:self];
}
[[GPPSignIn sharedInstance] signOut];
}
,你能否告诉prepareforsegue的利用代码,也可以请您给您的目的地视图控制器的名字吗? –
