这几天文件上传突然不能用了，php返回错误是3，查了一圈磁盘空间，权限，配额都没发现问题，最后把apache换成nginx+phpfpm还是同样错误。这时才感觉可能是网络原因，通过ssh端口转发访问，成功上传

Mono运行c#偶发异常

写的一个负载均衡程序，在Win下运行良好，Mac和Linux下用Mono运行总会偶发一些Native异常 T.T

Debug info from gdb:
xcode-select: error: no developer tools were found at ‘/Applications/Xcode.app’, and no install could be requested (perhaps no UI is present), please install manually from ‘developer.apple.com’.

Got a SIGABRT while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

NSString 相关
作者: nick

NSString 与 std::string 互转：
NSString -> std::string
NSString* s = @”test”;
std::string str = [s UTF8String];
std::string -> NSString
std::string str = “test”;
NSString* s = [NSString stringWithCString:str.c_str() encoding:[NSString defaultCStringEncoding]];
NSString 格式化：
[NSString stringWithFormat:@”…..”, p1, p2…];
多语言：
NSLocalizedstring是系统默认的本地化它会自动取Localizable.strings里面的键值。
如果自己新建了一个的xxx.strings文件，取值的时候要用NSLocalizedStringFromTable(@”label”, @”xxx”, nil);
Localize有时候没有中文可以选，只要在目录中 cp -R en.lproj zh-Hans.lproj 复制一份，然后添加到项目中即可

cocos2dx 3.x Android中加入AdMob
作者: nick
日期: 30 12 月, 2016

观察 AppActivity.java:
public class AppActivity extends Cocos2dxActivity
启动的Activity是继承Cocos2dxActivity；
Cocos2dxActivity 存在 mFrameLayout，那就直接在里面设置个PopupWindow即可；
Activity本身空无一物，直接加上一下代码即可：
public class AppActivity extends Cocos2dxActivity {
private AdView adView;
private PopupWindow popUp;
private static AppActivity _activity;
private LinearLayout layout;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
_activity = this;
adView = new AdView(this);
adView.setAdUnitId("ca-app-pub-xxxxxxxxxxxxxxxx/xxxxxxxxxx"); // 这里填自己的AdUnitId
adView.setAdSize(AdSize.BANNER);
adView.setAdListener(new AdmobListener()); // AdmobListener 中处理收到事件
}
public static void showHideAdPopup() { // 静态方法供Native代码调用
_activity._showHideAdPopup();
}
public void _showHideAdPopup() {
if (popUp == null) {
runOnUiThread(new Runnable() {
@Override
public void run() {
try {
popUp = new PopupWindow(_activity);
popUp.setWidth(360);
popUp.setHeight(50);
popUp.setWindowLayoutMode(WindowManager.LayoutParams.WRAP_CONTENT,
WindowManager.LayoutParams.WRAP_CONTENT);
popUp.setClippingEnabled(false);
layout = new LinearLayout(_activity);
layout.setPadding(-10, -10, -10, -10); // 不加这句AdView可能会没有足够Size容纳加载不了
MarginLayoutParams params = new MarginLayoutParams(
LayoutParams.MATCH_PARENT,
LayoutParams.MATCH_PARENT);
params.setMargins(0, 0, 0, 0);
layout.setOrientation(LinearLayout.VERTICAL);
layout.addView(adView, params);
popUp.setContentView(layout);
AdRequest adRequest = new AdRequest.Builder()
.addTestDevice("xxxxxxxxxxxxxxxxxxxxxxxx") // 申明测试设备，不加乱点会被ban账号，在logcat中搜AdRequest可以看到
.build();
_activity.adView.loadAd(adRequest);
popUp.showAtLocation(mFrameLayout, Gravity.BOTTOM, 0, 0);
popUp.update();
} catch (Exception ex) {
Toast.makeText(AppActivity.this, ex.getMessage(), Toast.LENGTH_SHORT).show();
}
}
});
} else { // 再次调用隐藏
runOnUiThread(new Runnable() {
@Override
public void run() {
layout.removeView(adView);
popUp.dismiss();
popUp = null;
}
});
}
}
private class AdmobListener extends AdListener {
@Override
public void onAdClosed() {
Log.d("", "Closed");
super.onAdClosed();
}
@Override
public void onAdFailedToLoad(int errorCode) {
Log.d("", "Failed");
super.onAdFailedToLoad(errorCode);
}
@Override
public void onAdLeftApplication() {
Log.d("", "Left");
super.onAdLeftApplication();
}
@Override
public void onAdLoaded() {
Log.d("", "Loaded");
super.onAdLoaded();
}
@Override
public void onAdOpened() {
Log.d("", "Opened");
super.onAdOpened();
}
}
@Override
public void onDestroy() {
if (adView != null) {
adView.destroy();
}
super.onDestroy();
}
}
Native 代码中通过cocos2d::JniHelper交互
记得判断CC_TARGET_PLATFORM，防止XCode编译ios时出错
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
#include "platform/android/jni/JniHelper.h"
const char* NativeActivityClassName = "org/cocos2dx/cpp/AppActivity";
#endif
void AdmobHelper::showAds() {
#if (CC_TARGET_PLATFORM == CC_PLATFORM_ANDROID)
cocos2d::JniMethodInfo t;
if (cocos2d::JniHelper::getStaticMethodInfo(t
, NativeActivityClassName
, "showHideAdPopup"
, "()V"))
{
t.env->CallStaticVoidMethod(t.classID, t.methodID);
t.env->DeleteLocalRef(t.classID);
}
#endif
}
cocos2dx 单点点击事件
作者: nick
日期: 7 12 月, 2016
没有评论
1、通过cocos2d::EventListenerTouchOneByOne::create()创建 listener;
2、多个listener addEventListenerWithSceneGraphPriority 按z-order顺序触发，需要自行判断点击范围;
3、onTouchBegan 中返回值为true才会触发后续Moved Ended Cancelled事件;
4、setSwallowTouches(true) 且onTouchBegan返回true时，不会触发其他的listener;

cocos compile 参数中要加上 –app-abi armeabi –ndk-toolchain arm-linux-androideabi-4.9
说明中app-abi默认为armeabi，实际上为arm64
ndk-toolchain根据实际情况指定版本
