iOS：foursquare请求失败

Question

I am assigned to work with foursquare just recently. I have an app that needs to be authenticated and access the foursquare environment. I am having trouble with the following code to access checkins. I had already successfully made the authentication but the thing is that when I made a check in request, an errorType invalid_auth code 401 appears. I just don't know what's wrong with this.

Here is my full code; I am using fsq wrapper I found in github:

#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_;

can you help me guys? any help will highly be appreciated.

Answer 1

https://developer.foursquare.com/overview/responses

401 (Unauthorized) The OAuth token was provided but was invalid.

Might you have somehow corrupted your oauth token?

Answer 2

我正在使用下面的代码，它为我工作：

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