我正在获取 Facebook 用户数据以自动完成注册文本字段。
问题:我做了一个测试,NSLog 快速返回信息,但是更新 TextFields.text 它延迟了。
代码:
- (IBAction)facebookProfile:(id)sender {
if(!_accountStore)
_accountStore = [[ACAccountStore alloc] init];
ACAccountType *facebookTypeAccount = [_accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierFacebook];
[_accountStore requestAccessToAccountsWithType:facebookTypeAccount
options:@{ACFacebookAppIdKey: @"417425124162461", ACFacebookPermissionsKey: @[@"email"]}
completion:^(BOOL granted, NSError *error) {
if(granted){
NSArray *accounts = [_accountStore accountsWithAccountType:facebookTypeAccount];
_facebookAccount = [accounts lastObject];
NSLog(@"Success");
[self me];
}else{
// ouch
NSLog(@"Fail");
NSLog(@"Error: %@", error);
}
}];
}
- (void)me {
NSURL *meUrl = [NSURL URLWithString:@"https://graph.facebook.com/me"];
SLRequest *meRequest = [SLRequest requestForServiceType:SLServiceTypeFacebook requestMethod:SLRequestMethodGET URL:meUrl parameters:nil];
meRequest.account = _facebookAccount;
[meRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) {
if (!error) {
NSDictionary *resultsDictionary = [responseData objectFromJSONData];
NSLog(@"%@", [resultsDictionary objectForKey:@"name"]);
// The problem is here. While NSLog runs in seconds showing Facebook User Name, the textfiend.text updates take about 10 seconds longer.
_tfName.text = [resultsDictionary objectForKey:@"name"];
_tfEmail.text = [resultsDictionary objectForKey:@"email"];
_tfGender.text = [resultsDictionary objectForKey:@"gender"];
_tfBirthday.text = [resultsDictionary objectForKey:@"birthday"];
}
}];
}
