小编NSD*_*ect的帖子

我正在尝试创建一个像Instagram这样的相机,用户可以看到一个盒子,图像会裁剪到那个盒子.由于某些原因,相机不会一直到达屏幕底部并在末端附近切断.我也想知道如何在正方形内将图像裁剪为320x320？

我有一个令牌,但一直收到此错误:"必须使用活动访问令牌来查询有关当前用户的信息." 任何帮助表示赞赏:)

    NSLog(@"TOKEN : %@",[[FBSession activeSession] accessToken]);

    NSString *picture = [NSString stringWithFormat:@"http://www.prowebdev.org/WooF/API/OpenGraph.php"];
    NSString *image = [NSString stringWithFormat:@"http://www.prowebdev.org/WooF/API/upload/356.jpg"];
    NSString *imageBool = [NSString stringWithFormat:@"true"];

    NSMutableDictionary *myDictionary = [NSMutableDictionary dictionaryWithObjects:[NSArray arrayWithObjects:picture,image,imageBool, nil] forKeys:[NSArray arrayWithObjects:@"picture",@"image[0][url]",@"image[1][user_generated]", nil]];

    FBRequest *request  = [FBRequest requestWithGraphPath:@"me/mydogwoofs:posted" parameters:myDictionary HTTPMethod:@"POST"];
    FBRequestConnection *connection  = [[FBRequestConnection alloc] init];
    [connection addRequest:request completionHandler:
     ^(FBRequestConnection *connection, id result, NSError *error) {
         if (!error && result) {
             NSLog(@"Posted!");
         }else{
             NSLog(@"ERROR - %@", error);
         }
     }];
    [connection start];
