ios开发教程_横竖屏切换 cocos2dx。
项目设置deploymentinfo ->device orientation都不勾选
appcontroller.mm

// for ios6, use supportedinterfaceorientations & shouldautorotate instead
- (nsuinteger) supportedinterfaceorientations{
#ifdef __iphone_6_0

#endif
}

return yes;
else
return no;
}
//这是replacescene时候的页面(先调用changedirection,后转向需要转屏的页面)
h文件
#if (cc_target_platform == cc_platform_ios)
#include "rootviewcontroller.h"
#endif
//声明转屏方法
void changedirection();
cpp文件,需要把cpp文件后缀改成mm
竖屏
void scene2::changedirection(){
#if cc_target_platform == cc_platform_ios
[rootviewcontroller changedir:true];
auto director = director::getinstance();
auto glview = director->getopenglview();
cocos2d::size framesize=glview->getframesize();
glview->setframesize(framesize.height,framesize.width);
director->getopenglview()->setdesignresolutionsize(1136.0f, 640.0f, resolutionpolicy::exact_fit);
#endif
}
横屏
void scene1::changedirection(){
#if cc_target_platform == cc_platform_ios
[rootviewcontroller changedir:false];
auto director = director::getinstance();
auto glview = director->getopenglview();
cocos2d::size framesize=glview->getframesize();
glview->setframesize(framesize.height,framesize.width);
director->getopenglview()->setdesignresolutionsize(640.0f,1136.0f, resolutionpolicy::exact_fit);
#endif
}
=======================================================
=======================android=======================
1.
修改目录下的：proj.android\src\org\cocos2dx\lib\cocos2dxactivity.java
添加下面3个 方法
//横屏
public static void changeland(){
scontext.setrequestedorientation(activityinfo.screen_orientation_landscape);
}
//竖屏
public static void changeport(){
scontext.setrequestedorientation(activityinfo.screen_orientation_portrait);
}
//获得当前屏幕方向
public static int getdirection(){
//int strdirec=scontext.getrequestedorientation();
//log.e("direction",new string(strdirec+""));
//system.out.println(strdirec);
return scontext.getrequestedorientation();
}
2.
//这是replacescene时候的页面(先调用changedirection,后转向需要转屏的页面)
h文件添加
#if cc_target_platform == cc_platform_android
#include
#include "platform/android/jni/jnihelper.h"
#endif
//声明转屏方法
void changedirection();
cpp文件添加
//竖屏转横屏
extern "c" //因为jni将java代码转过来是c的，所以c++引用得加上
{
void changeland();
}
void scene2::changedirection(){
#if (cc_target_platform == cc_platform_android)
//判断当前设备的方向
//如果是横向就不做操作,竖向就强制横屏
jnimethodinfo info;
if(jnihelper::getstaticmethodinfo(info,"org/cocos2dx/lib/cocos2dxactivity","getdirection","()i")){
jint iret=info.env->callstaticintmethod(info.classid,info.methodid);
if(iret==1){
if(jnihelper::getstaticmethodinfo(info,"org/cocos2dx/lib/cocos2dxactivity","changeland","()v"))
{
info.env->callstaticvoidmethod(info.classid,info.methodid);
}
auto director = director::getinstance();
auto glview = director->getopenglview();
size framesize=glview->getframesize();
glview->setframesize(framesize.height,framesize.width);
director->getopenglview()->setdesignresolutionsize(1136.0f, 640.0f, resolutionpolicy::exact_fit);
}
}
#endif
}
//横屏转竖屏
extern "c" //因为jni将java代码转过来是c的，所以c++引用得加上
{
void changeport();
}
void scene1::changedirection(){
#if (cc_target_platform == cc_platform_android)
//判断当前设备的方向
//如果是竖向就不做操作,横向就强制竖屏
jnimethodinfo info;
if(jnihelper::getstaticmethodinfo(info,"org/cocos2dx/lib/cocos2dxactivity","getdirection","()i")){
jint iret=info.env->callstaticintmethod(info.classid,info.methodid);
if(iret==0){
if(jnihelper::getstaticmethodinfo(info,"org/cocos2dx/lib/cocos2dxactivity","changeport","()v"))
{
info.env->callstaticvoidmethod(info.classid,info.methodid);
}
auto director = director::getinstance();
auto glview = director->getopenglview();
size framesize=glview->getframesize();
glview->setframesize(framesize.height,framesize.width);
glview->setdesignresolutionsize(640.0f, 1136.0f, resolutionpolicy::exact_fit);
}
}
#endif
}
3.
如在windows下调试
//横屏
#if cc_target_platform == cc_platform_win32
auto director = director::getinstance();
auto glview = director->getopenglview();
glview->setframesize(656.0f,370.0f);//自定义的大小，1136*640的话太大
director->getopenglview()->setdesignresolutionsize(1136.0f, 640.0f, resolutionpolicy::exact_fit);
#endif
//竖屏
#if cc_target_platform == cc_platform_win32
auto director = director::getinstance();
auto glview = director->getopenglview();
glview->setframesize(370.0f,656.0f);
//size framesize=glview->getframesize();
glview->setdesignresolutionsize(640.0f,1136.0f, resolutionpolicy::exact_fit);
#endif
最后附上androidmainfest.xml
package="org.cocos.cocosproject"
android:versioncode="1"
android:versionname="1.0"
android:installlocation="auto">
android:icon="@drawable/icon">
android:value="cocos2dcpp" />
android:label="@string/app_name"
android:screenorientation="portrait"
android:theme="@android:style/theme.notitlebar.fullscreen"
android:configchanges="orientation|keyboardhidden">
android:smallscreens="true"
android:normalscreens="true"
android:largescreens="true"
android:xlargescreens="true"/>
