ios开发教程_横竖屏切换 cocos2dx。

项目设置deploymentinfo ->device orientation都不勾选

appcontroller.mm

-(nsuinteger)application:(uiapplication *)application supportedinterfaceorientationsforwindow:(uiwindow *)window{

return uiinterfaceorientationmaskallbutupsidedown;

}

rootviewcontroller.h

+(void)changedir:(bool)bisleft;

rootviewcontroller.mm

- (bool)shouldautorotatetointerfaceorientation:(uiinterfaceorientation)interfaceorientation {

return uiinterfaceorientationislandscape( interfaceorientation );

}

// for ios6, use supportedinterfaceorientations & shouldautorotate instead

- (nsuinteger) supportedinterfaceorientations{

#ifdef __iphone_6_0

return uiinterfaceorientationmaskallbutupsidedown;

#endif

}

static bool s_needorientation=false;

+(void)changedir:(bool)bisleft{

if(s_needorientation == bisleft )

return;

s_needorientation = bisleft ;

[[uidevice currentdevice] performselector:@selector(setorientation:)

withobject:

bisleft ? (id)uideviceorientationlandscapeleft : (id)uideviceorientationportrait];

}

- (bool) shouldautorotate {

//bool bisportraitcur = ([[uiapplication sharedapplication] statusbarorientation] == uiinterfaceorientationlandscapeleft);

bool bisleftcur=([uidevice currentdevice].orientation==uideviceorientationportrait);

//cclog("s_needorientation:%d",s_needorientation);

//cclog("bisportraitcur:%d",bisleftcur);

if( bisleftcur != s_needorientation )

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"/>
