Iphone 开发笔记
/////////////////////////////////////////////////////////////////
// 基本框架
/////////////////////////////////////////////////////////////////
基本框架：
Library 一些帮助类
--UserLib 用户自定义帮助类
--Lib 特定功能的帮助类
Modal 实体
Images 图片
Rescources ui
Classes ui的.h.m文件
（ui的命名以Controller结尾,例StationFunctionController.xib）
导航应用程序的创建：
1.创建导航的页面的ui
-- .xib ( empty interface )
-- .h ( Objective-C class )
-- .m
修改.h文件，使它继承UIViewController
修改.xib文件，选择File’s Owner，修改Calss为 之前创建的.h
2.再AppDelegate.h中实例化UITabBarController , UITabBar , UINavigationController（有几个导航页面就实例几个UINavigationController对象）
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <QuartzCore/QuartzCore.h>
#import "StationFunctionController.h"
#import "CompanyInformationController.h"
#import "PersonalInformationController.h"
#import "plistReader.h"
#import "LoginController.h"
#import "CompanyChooseController.h"
#import "TabBarController.h"
#import "MyTabBarDelegate.h"
#import "LogoutController.h"
int isReloadsf;
int isReloadci;
int isReloadpi;
int isReloadlo;
@interface AppDelegate : NSObject <UIApplicationDelegate,UITabBarControllerDelegate,MyTabBarDelegate>{
TabBarController *tabController;
UITabBar *tabBar;
UINavigationController *stationFunNav;
UINavigationController *companyInfoNav;
UINavigationController *personalInfoNav;
UINavigationController *logoutNav;
UITextField *accountField;
UITextField *passwdField;
}
@property (strong, nonatomic) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *tabController;
@property (nonatomic, retain) IBOutlet UITabBar *tabBar;
-(void)LoadTab;
-(void)IsLogin;
@end
注：需要创建MainWindow.xib，布局如下：
其中的App Delegate是一个Object（class为AppDelegate）
3.接下来就是设置uitabbarcontroller了,附上代码：
-(void)LoadTab{
//页面对象
StationFunctionController *sfController = [[StationFunctionController alloc]initWithNibName:@"StationFunctionController" bundle:nil];
CompanyInformationController *ciController = [[CompanyInformationController alloc]initWithNibName:@"CompanyInformationController" bundle:nil];
PersonalInformationController *piController = [[PersonalInformationController alloc]initWithNibName:@"PersonalInformationController" bundle:nil];
//实例navgationController
stationFunNav = [[UINavigationController alloc] initWithRootViewController:sfController];
companyInfoNav = [[UINavigationController alloc] initWithRootViewController:ciController];
personalInfoNav = [[UINavigationController alloc] initWithRootViewController:piController];
//stationFunNav.navigationBar.tintColor = [UIColor colorWithRed:0.0f green:0.55f blue:0.60f alpha:1.0f];
//companyInfoNav.navigationBar.tintColor = [UIColor colorWithRed:0.0f green:0.55f blue:0.60f alpha:1.0f];
//personalInfoNav.navigationBar.tintColor = [UIColor colorWithRed:0.0f green:0.55f blue:0.60f alpha:1.0f];
UITabBarItem *sfItem = [[UITabBarItem alloc]initWithTitle:@"站内功能" image:[UIImage imageNamed:@".."] tag:0];
UITabBarItem *ciItem = [[UITabBarItem alloc]initWithTitle:@"公司信息" image:[UIImage imageNamed:@".."] tag:1];
UITabBarItem *piItem = [[UITabBarItem alloc]initWithTitle:@"个人信息" image:[UIImage imageNamed:@".."] tag:2];
//UITabBarItem *logoutItem = [[UITabBarItem alloc]initWithTitle:@"退出" image:[UIImage imageNamed:@""] tag:3];
stationFunNav.tabBarItem = sfItem;
companyInfoNav.tabBarItem = ciItem;
personalInfoNav.tabBarItem = piItem;
NSArray *array = [NSArray arrayWithObjects:stationFunNav,companyInfoNav,personalInfoNav,nil];
tabController = [[UITabBarController alloc]init];
tabController.viewControllers = array;
tabController.delegate = self;
[_window addSubview:tabController.view];
[self.window makeKeyAndVisible];
[sfItem release];
[ciItem release];
[piItem release];
[sfController release];
[ciController release];
[piController release];
[stationFunNav release];
[companyInfoNav release];
[personalInfoNav release];
}
在didFinishLaunchingWithOptions方法中调用它。

*/
}
- (void)applicationDidEnterBackground:(UIApplication *)application
{
/*

}
- (void)applicationWillEnterForeground:(UIApplication *)application
{
/*

*/
}
- (void)applicationDidBecomeActive:(UIApplication *)application
{
/*

*/
}

// 关于Login 页面
/////////////////////////////////////////////////////////////////
判断指定plist文件中是否有你想要的数据来弹出登录页面
(网上有这么一段话：
| window中不要添加多个subview，如想跳转，请用UINavigationController的push方法push一个新的UIViewController，或者使用UIViewController的presentModelViewController方法来弹出一个新的页面，注意此页面会遮住下面的tab bar。 |
)
使用 presentModalViewController方法或许效果比pushview好点:
presentModalViewController:
[stationFunNav presentModalViewController:loginController animated:YES];
pushViewController:
[stationFunNav pushViewController:loginController animated:YES];
还有是alertview的登录弹出框（MAlertView是一个继承UIAlerView的.h.m）
//设置登录
accountField = [[UITextField alloc]init];
passwdField = [[UITextField alloc]init];
//设置密码框
[passwdField setSecureTextEntry:YES];
MAlertView *alertLogin = [[MAlertView alloc] initWithTitle:@"登录" message:nil delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil];
[alertLogin addTextField:accountField placeHolder:@"这里输入用户ID"];
[alertLogin addTextField:passwdField placeHolder:@"这里输入密码"];
[alertLogin show];
presentModalViewController出来的页面用dismissModalViewControllerAnimated来关闭
关于<libxml/tree.h>
在 bulid -> Header Search Paths 添加/usr/include/libxml2
代码添加uibutton
UIButton* button = [UIButton buttonWithType:100];
button.frame = CGRectMake(12,12,70,30);
[button setTitle:@"考勤" forState:UIControlStateNormal];
// 注册按钮按下时的处理函数
[button addTarget:self action:@selector(countup:)
forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
buttontype 可以尝试着用数字试试，（似乎是私有api的写法）
关于自定义的cell
在设置xib时，File’s Owner为object , uitabviewcell 为你自定义的class
引用的时候：
dateChooseCell = (DateSelectCell *)[tableView dequeueReusableCellWithIdentifier:@"DateSelectCell"];
NSArray *nib = [[NSBundle mainBundle]loadNibNamed:@"DateSelectCell" owner:self options:nil];
dateChooseCell = [nib objectAtIndex:0];
关闭键盘
[tfldMedicineName resignFirstResponder];
获得焦点，打开键盘
[txtUserID becomeFirstResponder];
增加动画
#import <QuartzCore/QuartzCore.h>
CGContextRef context = UIGraphicsGetCurrentContext();
[UIView beginAnimations:nil context:context];
[UIView setAnimationDuration:0.5f];
[UIView setAnimationDelegate:self];
button.frame = CGRectMake(20,6,80,30);
button.alpha = 1;
button01.frame = CGRectMake(120,6,80,30);
button01.alpha = 1;
button02.frame = CGRectMake(220,6,80,30);
button02.alpha = 1;
[tableview setFrame:CGRectMake(0.0f, 30.0f, 320.0f, 420.0f)];
[UIView commitAnimations];
//动画结束时
- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag{}
背景的渐变色（还是用图片吧..）
self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bg.png"]];
iPhone开发中各种动画翻页效果整理
iphone中存在很多好看的动画效果，用于页面的切换等。其中某些是apple私有的，据说私有的无法通过apple的审批。 最近工作中刚好用到过其中的某些动画，所以在网上搜了下资料，了解了下这些动画。这里就自己的理解做一下总结。
UIView 动画
官方API中，使用UIView可以设置5个动画效果，分别为：
UIViewAnimationTransitionNone 不使用动画 UIViewAnimationTransitionFlipFromLeft 从左向右旋转翻页 UIViewAnimationTransitionFlipFromRight 从右向左旋转翻页，与UIViewAnimationTransitionFlipFromLeft相反 UIViewAnimationTransitionCurlUp 卷曲翻页，从下往上 UIViewAnimationTransitionCurlDown 卷曲翻页，从上往下
详细请参见UIViewAnimationTransition，举例如下：
[UIView beginAnimations:@"animationID" context:nil];//开始一个动画块，第一个参数为动画块标识 [UIView setAnimationDuration:0.5f];//设置动画的持续时间 [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; //设置动画块中的动画属性变化的曲线，此方法必须在beginAnimations方法和commitAnimations，默认即为UIViewAnimationCurveEaseInOut效果。 //详细请参见UIViewAnimationCurve [UIView setAnimationRepeatAutoreverses:NO];//设置是否自动反转当前的动画效果 [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; //设置过渡的动画效果，此处第一个参数可使用上面5种动画效果。 [self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:0];//页面翻转 [UIView commitAnimations];//提交动画
公共动画效果
使用CATransiton可以设置4种动画效果，分别为：
NSString * const kCATransitionFade;//渐渐消失 NSString * const kCATransitionMoveIn;//覆盖进入 NSString * const kCATransitionPush;//推出 NSString * const kCATransitionReveal;//与MoveIn相反
举例说明：
CATransition *animation = [CATransition animation]; animation.duration = 0.5f; animation.timingFunction = UIViewAnimationCurveEaseInOut; animation.type = kCATransitionPush;//设置上面4种动画效果 animation.subtype = kCATransitionFromTop;//设置动画的方向，有四种，分别为kCATransitionFromRight、kCATransitionFromLeft、kCATransitionFromTop、kCATransitionFromBottom [self.view.layer addAnimation:animation forKey:@"animationID"];
私有动画
iphone种还有很多动画是苹果私有的，例如删除照片的动画等， 私有动画可以直接在animation.type中传入动画的字符串即可。动画有以下几种：
cube：像立方体一样翻转 suckEffect：渐渐缩小，与删除照片动画一样 oglFlip：上下旋转，当subType为fromLeft或者fromRight时，与UIViewAnimationTransitionFlipFromLeft和UIViewAnimationTransitionFlipFromRight一样 rippleEffect:水波效果 pageCurl：与UIViewAnimationTransitionCurlUp一样 pageUnCurl：与UIViewAnimationTransitionCurlDown一样 cameraIrisHollowOpen：First half of cameraIris. cameraIrisHollowClose：Second half of cameraIris
以上所有动画效果的demo请见http://www.cocoachina.com/bbs/read.php?tid-11820.html
UIViewAnimationState描述：http://www.iphonedevwiki.net/index.php/UIViewAnimationState
同时，本人在使用UIView实现suckEffect缩小的效果过程中遇到一个问题（不知道如何定位），经过搜索终觅得解决方法，分享如下：
[UIView beginAnimations:@"suck" context:NULL]; [UIView setAnimationTransition:103 forView:self.view cache:YES]; [UIView setAnimationDuration:0.5f]; if (self.interfaceOrientation == UIInterfaceOrientationPortrait || self.interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown) { [UIView setAnimationPosition:CGPointMake(44, 42)]; }else { [UIView setAnimationPosition:CGPointMake(320 , 42)]; } [UIView commitAnimations];
其中setAnimationPosition方法就是用于设置缩小点的位置的，此处虽然会报一个警告，但是结果还是正确的。
关于软键盘弹出时的上移
先设置textfield的delegate = self
- (void)textFieldDidBeginEditing:(UITextField *)textField
{
//获取这个textfield在tableview中的第几行
//再更具第几行设置页面高度（暂时还没有找到很好的通用方法来改变高度，网上也有说textfield嵌套再tableview中时，是可以自动调整页面高度的，不知道怎么设置）（前些天找到了，要继承UItabviewController而不是uiviewcontroller）
UITableViewCell *cell = (UITableViewCell *)[textField superview] ;
NSInteger idx = [[self.tbView indexPathForCell:cell] row];
NSLog([NSString stringWithFormat:@"index:%d",idx]);
switch (idx) {
case 3:
[self.tbView setContentOffset:CGPointMake(0, 130) animated:YES];//上移 130
break;
case 4:
[self.tbView setContentOffset:CGPointMake(0, 160) animated:YES];
break;
case 5:
[self.tbView setContentOffset:CGPointMake(0, 170) animated:YES];
break;
default:
[self.tbView setContentOffset:CGPointMake(0, 0) animated:YES];
break;
}
}
