iOS：foursquare請求失敗

Question

我剛被分配到與Foursquare合作。 我有一個需要進行身份驗證並訪問Foursquare環境的應用程序。 我在使用以下代碼訪問簽入時遇到麻煩。 我已經成功進行了身份驗證，但事實是，當我提出簽入請求時，出現errorType invalid_auth代碼401。 我只是不知道這是怎么回事。

這是我的完整代碼； 我正在使用在github中找到的fsq包裝器：

#import "FSQViewController.h"

#define kClientID      @"XXXXXXXXXXXXXXXXXXXXXXX"
#define kCallbackURL   @"invitation://foursquare"

@interface FSQViewController()
@property(nonatomic,readwrite,strong) BZFoursquare *foursquare;
@property(nonatomic,strong) BZFoursquareRequest *request;
@property(nonatomic,copy) NSDictionary *meta;
@property(nonatomic,copy) NSArray *notifications;
@property(nonatomic,copy) NSDictionary *response;
@end


@implementation FSQViewController

@synthesize foursquare = foursquare_;
@synthesize request = request_;
@synthesize meta = meta_;
@synthesize notifications = notifications_;
@synthesize response = response_;

        foursquare_.version = @"20120206";
        foursquare_.locale = [[NSLocale currentLocale]objectForKey:NSLocaleLanguageCode];

你能幫我嗎？ 任何幫助將不勝感激。

401（未經授權）已提供OAuth令牌，但無效。

您可能以某種方式損壞了您的oauth令牌？

Answer 2

我正在使用下面的代碼，它為我工作：

NSDictionary *parameters = @{@"venueId": @"4a0c6465f964a5202a751fe3", @"broadcast": @"public",@"oauth_token":kClientID};
