Question

大家好 只是想知道我如何修改我的代码以将分数发布到 Facebook

目前所有工作都在 Facebook 上发布以下内容，只是没有分数

#import "GameOverViewController.h"
#import "SoundEffects.h"
#import "FBConnect.h"


@implementation GameOverViewController

@synthesize scoreLabel, highScore;

更改：

dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@ just played SpaceRide on the iPhone!\",\"href\":\"http://www.spaceride.me/\",\"caption\":\"%@ must be really skillful!\",\"description\":\"\",\"media\":[{\"type\":\"image\",\"src\":\"http://www.spaceride.me/fbicon.png\",\"href\":\"http://www.spaceride.me/\"}]}",
                         _facebookName, _facebookName];

更改为：

dialog.attachment = [NSString stringWithFormat:@"{\"name\":\"%@ just got %d playing SpaceRide on the iPhone!\",\"href\":\"http://www.spaceride.me/\",\"caption\":\"%@ must be really skillful!\",\"description\":\"\",\"media\":[{\"type\":\"image\",\"src\":\"http://www.spaceride.me/fbicon.png\",\"href\":\"http://www.spaceride.me/\"}]}",
                         _facebookName, score, _facebookName];

将“分数”更改为整数分数变量的名称。
