quick-cocos2d-x GameCenter 排行榜
1、编写自己的oc类 GameKitHelper.h和GameKitHelper.m
#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
#import <GameKit/GameKit.h>
@interface GameKitHelper : NSObject <GKLeaderboardViewControllerDelegate, GKAchievementViewControllerDelegate, GKMatchmakerViewControllerDelegate, GKMatchDelegate>{
BOOL gameCenterAvailable;
BOOL userAuthenticated;
}
@property (assign, readonly) BOOL gameCenterAvailable;
+ (GameKitHelper *)sharedGameKitHelper;
- (void) authenticateLocalUser;
- (void) showLeaderboard;
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController;
- (void) reportScore: (int64_t) score forCategory: (NSString*) category;
@end
//
// GameKitHelper.m
// nocmd

#import "GameKitHelper.h"
@implementation GameKitHelper
@synthesize gameCenterAvailable;
static GameKitHelper *sharedHelper = nil;
static UIViewController* currentModalViewController = nil;
+ (GameKitHelper *) sharedGameKitHelper {
if (!sharedHelper) {
sharedHelper = [[GameKitHelper alloc] init];
}
return sharedHelper;
}
//用于验证
- (BOOL)isGameCenterAvailable {
// check for presence of GKLocalPlayer API
Class gcClass = (NSClassFromString(@"GKLocalPlayer"));
// check if the device is running iOS 4.1 or later
NSString *reqSysVer =@"4.1";
NSString *currSysVer = [[UIDevice currentDevice] systemVersion];
BOOL osVersionSupported = ([currSysVer compare:reqSysVer
options:NSNumericSearch] != NSOrderedAscending);
return (gcClass && osVersionSupported);
}
- (id)init {
if ((self = [super init])) {
gameCenterAvailable = [self isGameCenterAvailable];
if (gameCenterAvailable) {
NSNotificationCenter *nc =
[NSNotificationCenter defaultCenter];
[nc addObserver:self
selector:@selector(authenticationChanged)
name:GKPlayerAuthenticationDidChangeNotificationName
object:nil];
}
}
return self;
}
//后台回调登陆验证
- (void)authenticationChanged {
if ([GKLocalPlayer localPlayer].isAuthenticated &&!userAuthenticated) {
NSLog(@"Authentication changed: player authenticated.");
userAuthenticated = TRUE;
} else if (![GKLocalPlayer localPlayer].isAuthenticated && userAuthenticated) {

}
}
- (void)authenticateLocalUser {
if (!gameCenterAvailable) return;
NSLog(@"Authenticating local user...");
if ([GKLocalPlayer localPlayer].authenticated == NO) {
[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:nil];
} else {
NSLog(@"Already authenticated!");
}
}
//显示排行榜
- (void) showLeaderboard
{

GKLeaderboardViewController *leaderboardController = [[GKLeaderboardViewController alloc] init];
if (leaderboardController != nil) {

}
}
//关闭排行榜回调
- (void)leaderboardViewControllerDidFinish:(GKLeaderboardViewController *)viewController{
if(currentModalViewController !=nil){
[currentModalViewController dismissModalViewControllerAnimated:NO];
[currentModalViewController release];

currentModalViewController = nil;
}
}
// 上传一个分数
- (void) reportScore: (int64_t) score forCategory: (NSString*) category
{
GKScore *scoreReporter = [[[GKScore alloc] initWithCategory:category] autorelease];
scoreReporter.value = score;
[scoreReporter reportScoreWithCompletionHandler:^(NSError *error) {
if (error != nil)
{
// handle the reporting error

//Instead, store the score object and attempt to report the player’s process at
//a later time.
}else {
NSLog(@"上传分数成功");
}
}];
}
@end
2、AppController.mm中 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 方法里面添加 [[GameKitHelper sharedGameKitHelper] authenticateLocalUser];认证GameCenter
3、显示排行榜数据。在AppController.mm中 添加showLeaderBoard方法,在lua中用luaoc调用
-- 显示排行榜
function showLeaderBoard( )
if device.platform == "ios" then
local args = {
platform = platform
}
local ok, ret = luaoc.callStaticMethod("AppController", "showLeaderBoard", nil) --没有返回默认nil
if ok then
print("getIsValid,ret:",ret)
return ret
else
print("shareEvent error code = ", ret)
return nil
end
end
end
// 显示排行
+ (void) showLeaderBoard{
[[GameKitHelper sharedGameKitHelper] showLeaderboard];
}
4、提交分数。在AppController.mm中 添加updateScore方法，在lua中调用方法
-- 上传分数
function updateScore( score )
if device.platform == "ios" then
local args = {
platform = platform,
score = score
}
local ok, ret = luaoc.callStaticMethod("AppController", "updateScore", args) --没有返回默认nil
if ok then
print("getIsValid,ret:",ret)
return ret
else
print("shareEvent error code = ", ret)
return nil
end
end
end
// 上传分数
+(void) updateScore:(NSDictionary *) dict
{
NSInteger score = [[dict objectForKey:@"score"] intValue];
[[GameKitHelper sharedGameKitHelper] reportScore:score forCategory:@"排行榜名称"];
}
