1、在ios/AppController.h 添加这两个协议 UIImagePickerControllerDelegate,UINavigationControllerDelegate

2、编写下面代码

//显示照相机
+(void) showImagePicker:(NSDictionary *)info {
    callBackId = [[info objectForKey:@"listener"] intValue];
    UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
    imagePicker.delegate = self;
    imagePicker.allowsEditing = true;
    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [[UIApplication sharedApplication].keyWindow.rootViewController presentViewController:imagePicker animated:YES completion:nil];
}
 
//选取照片完成
+(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
    NSLog(@"%@",info);
    if ([[info objectForKey:UIImagePickerControllerMediaType] isEqualToString:@"public.image"]) {
        UIImage *img = [info objectForKey:UIImagePickerControllerEditedImage];
        [self saveImage:img];
    } else {
         
    }
     
    [picker dismissViewControllerAnimated:YES completion:nil];
}
 
// 取消选择
+(void)imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
    [picker dismissViewControllerAnimated:YES completion:nil];
}
 
//保存图片
+(void)saveImage:(UIImage *)img
{
    BOOL success;
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error;
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *imgFilePath = [documentsDirectory stringByAppendingPathComponent:@"headPhoto.png"];
    success = [fileManager fileExistsAtPath:imgFilePath];
    std::string newImgPath = cocos2d::CCFileUtils::getInstance()->getWritablePath() + "/headPhoto.png";
    if (success) {
        success = [fileManager removeItemAtPath:[NSString stringWithFormat:@"%s",newImgPath.c_str()] error:&error];
        NSLog(@"success 2 %d",success);
    }
    // 更改尺寸
    UIImage * smallImage = [self thumbnailWithImageWithoutScale:img size:CGSizeMake(80, 80)];
    [UIImageJPEGRepresentation(smallImage, 1.0f) writeToFile:[NSString stringWithFormat:@"%s",newImgPath.c_str()] atomically:YES];
    // 新的照片地址回调给lua
    cocos2d::LuaObjcBridge::pushLuaFunctionById(callBackId);
//    cocos2d::LuaObjcBridge::getStack()->pushString([imgFilePath cStringUsingEncoding:NSUTF8StringEncoding]);
    cocos2d::LuaObjcBridge::getStack()->pushString(newImgPath.c_str());
    cocos2d::LuaObjcBridge::getStack()->executeFunction(1);
    cocos2d::LuaObjcBridge::releaseLuaFunctionById(callBackId);
     
}
// 实现缩略图
+(UIImage *) thumbnailWithImageWithoutScale:(UIImage *)img size:(CGSize)asize
{
    UIImage * newImg;
    if (nil == img) {
        newImg = nil;
    }else{
        CGSize oldsize = img.size;
        CGRect rect;
        if(asize.width/asize.height > oldsize.width/oldsize.height){
            rect.size.width = asize.height * oldsize.width / oldsize.height;
            rect.size.height = asize.width;
            rect.origin.x = (asize.width - rect.size.width) / 2;
            rect.origin.y = 0;
        }else{
            rect.size.width = asize.width;
            rect.size.height = asize.width * oldsize.height / oldsize.width;
            rect.origin.x = 0;
            rect.origin.y = (asize.height - rect.size.height) / 2;
        }
        UIGraphicsBeginImageContext(asize);
        CGContextRef content = UIGraphicsGetCurrentContext();
        CGContextSetFillColorWithColor(content, [[UIColor clearColor] CGColor]);
        UIRectFill(CGRectMake(0, 0, asize.width, asize.height));
        [img drawInRect:rect];
        newImg = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
    }
    return newImg;
}

3、在lua里面实现

if device.platform == "ios" then
	local function callBack( imgFileName )
	        //重新加载文理
		cc.Director:getInstance():getTextureCache():reloadTexture(imgFileName)
		display.newSprite(imgFileName):addTo(self):pos(display.cx,display.cy)
	end
	luaoc.callStaticMethod("AppController","showImagePicker",{listener = callBack})
end

- (void)applicationWillResignActive:(UIApplication *)application {

Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.

Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.

cocos2d::Director::getInstance()->pause();

}

- (void)applicationDidBecomeActive:(UIApplication *)application {

Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.

cocos2d::Director::getInstance()->resume();

}

- (void)applicationDidEnterBackground:(UIApplication *)application {

Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.

If your application supports background execution, called instead of applicationWillTerminate: when the user quits.

cocos2d::Application::getInstance()->applicationDidEnterBackground();

}

- (void)applicationWillEnterForeground:(UIApplication *)application {

Called as part of transition from the background to the inactive state: here you can undo many of the changes made on entering the background.

cocos2d::Application::getInstance()->applicationWillEnterForeground();

}

- (void)applicationWillTerminate:(UIApplication *)application {

Called when the application is about to terminate.

See also applicationDidEnterBackground:.

}

#pragma mark -

- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application {

Free up as much memory as possible by purging cached data objects that can be recreated (or reloaded from disk) later.

[super dealloc];
