wp 和sp

1. sp和wp 的区别。

    wp 就是弱，弱到与普通指针的唯一区别就是可以升级为sp。

    sp 就是强， 强到完全控制其生命周期。

日常笔记

下载代码：
1.先将svn_checkout文件拷贝到相应的目录下
2.切换到该目录键入命令：./svn_checkout
3.(按版本号下载) svn co  http://10.34.22.125:6801/svn/JS_WT_SVN/JS100R002/trunk -r 16013

查看版本信息：
cd trunk
svn info

解压patch_sorucedir
./prepare.sh

代码更新
cd truck
rm -rf sorucedir
svn up
./prepare.sh

编译命令
整体编译
cd truck/sorucedir
source build/envsetup.sh
tapas <tapas.in
./mk-all.sh 64/128
单个编译
source build/envsetup.sh
tapas <tapas.in
cd app
mm

编译重新指向
1>2.txt 2>&1

======================编译驱动================================
1、切换目录到相应的路径：Z:\songjia\JS100R002\trunk\Jonas\device\js\jschanping\driver\sdk
2、输入命令：make -f mpi.mk -j 128(表示启动多少个线程来编译,这里为128个)


=============================ADB===============================
adb使用
adb kill-server
adb connect IP:5555
adb remount

单个服务:
adb disconnect IP:5555
adb connect IP:5555
adb -s IP:5555 remount

上传文件:
adb push DisplaySetting.apk /data/app
安装应用:
adb install DisplaySetting.apk
adb -s 10.85.185.43:5555 install out/target/product/jschanping/system/app/AppWidgetSwitcher.apk
卸载应用:
adb uninstall DisplaySetting.apk

查看当前连接服务：
devices

=======================基本命令======================
查找文件：
find -name "*.cpp"(所有后缀为.cpp) | xargs grep "rotateX"(文件名)


设置IP
busybox ifconfig eth0 IP


设置权限
mount -o remount  rwx dir

返回操作平台：
Ctrl+c/Ctrl+d

删除目录及子文件：
rm [dirctory name] -rf


=========================单板==============================
查看IP配置：
输入：busybox ifconfig



==========================android4.0 bash环境设置==============================

source build/envsetup.sh
lunch godbox-eng


=========================单板IP设置===========================
查看IP：ifconfig eth0
动态获取IP：netcfg eth0 dhcp
分配IP: ifconfig eth0 10.107.152.199
FileZilla板子端设置:busybox tcpsvd -v 0 21 busybox ftpd -w /system/app &

导航栏中添加多个UIBarButtonItem

UIToolbar *tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 95, 45)];
[tools setTintColor:[self.navigationController.navigationBar tintColor]];
[tools setAlpha:[self.navigationController.navigationBar alpha]];

NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:2];
UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd
																																				 target:self action:@selector(btnClick:)];
UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithTitle:@"Edit" style:UITabBarSystemItemContacts target:self action:@selector(btnClick:)];
[buttons addObject:button1];
[button1 release];
[buttons addObject:button2];
[button2 release];
[tools setItems:buttons animated:NO];
[buttons release];

UIBarButtonItem *myBtn = [[UIBarButtonItem alloc] initWithCustomView:tools];
self.navigationItem.rightBarButtonItem = myBtn;

[myBtn release];
[tools release];
