iphone开发备忘
1. 添加sqlite框架的路径如下：/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/usr/libsqlite3.dylib
2. iPhone开发不使用xib文件的方法：
修改main.m里的UIApplicationMain参数为
UIApplicationMain(argc, argv, nil, @"AppDelegate");// AppDelegate为你的ApplicationDelegateAppDelegate：UIWindow *localWindow = [ initWithFrame: [ bounds]];localWindow.backgroundColor = ;self.window = localWindow;;navigationController = [ initWithRootViewController:[ init]];];;
3. SQLITE建表语句
CREATE TABLE accountbook(id integer primary key autoincrement,price number,costtime date,categorycode varchar(2),categoryname varchar(20),year varchar(4),month varchar(2),day varchar(2));
4. linux/MAC下强制结束进程
ps -ef //查看进程号
kill -9 进程号 //强制结束
5. iphone程序设置启动横屏
只要在Info.plist里面加UIInterfaceOrientation
给个 UIInterfaceOrientationLandscapeRight 就可以了
6. 彩色UIProgressView

7. Cover Flow Effect

8. 设置uitableview backgroundcolor:
正常情况下：
self.tableView.backgroundColor = ];
grouped tableview:
;
init] autorelease]];
;
//设置底色为无色
9 工具栏居中
//添加底部拍照的工具栏 //左空格 UIBarButtonItem *leftflexible = [ initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]; //右空格 UIBarButtonItem *rightflexible = [ initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]; UIBarButtonItem *cameraitem = [[ initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action: @selector(beginScan)] autorelease]; NSArray *myToolbarItems = [ initWithObjects: leftflexible,cameraitem,rightflexible, nil]; ;
