Iphone 開發筆記

 

 

 

/////////////////////////////////////////////////////////////////

// 基本框架

/////////////////////////////////////////////////////////////////

 

基本框架：

Library  一些幫助類

   --UserLib  用戶自定義幫助類

   --Lib      特定功能的幫助類

Modal   實體

Images   圖片

Rescources     ui

Classes   ui的.h.m文件

（ui的命名以Controller結尾,例StationFunctionController.xib）

 

 

導航應用程序的建立：

 

1.建立導航的頁面的ui

    -- .xib  ( empty interface )

-- .h  ( Objective-C class )

-- .m

修改.h文件，使它繼承UIViewController

修改.xib文件，選擇File’s Owner，修改Calss爲 以前建立的.h

 

2.再AppDelegate.h中實例化UITabBarController , UITabBar , UINavigationController（有幾個導航頁面就實例幾個UINavigationController對象）

#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：須要建立MainWindow.xib，佈局以下：

其中的App Delegate是一個Object（class爲AppDelegate）

 

3.接下來就是設置uitabbarcontroller了,附上代碼：

-(void)LoadTab{

   

    //頁面對象

    StationFunctionController *sfController = [[StationFunctionController alloc]initWithNibName:@"StationFunctionController" bundle:nil];

    CompanyInformationController *ciController = [[CompanyInformationController alloc]initWithNibName:@"CompanyInformationController" bundle:nil];

    PersonalInformationController *piController = [[PersonalInformationController alloc]initWithNibName:@"PersonalInformationController" bundle:nil];

   

   

   

    //實例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:@"站內功能" image:[UIImage imageNamed:@".."] tag:0];

    UITabBarItem *ciItem = [[UITabBarItem alloc]initWithTitle:@"公司信息" image:[UIImage imageNamed:@".."] tag:1];

    UITabBarItem *piItem = [[UITabBarItem alloc]initWithTitle:@"我的信息" 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方法中調用它。

/////////////////////////////////////////////////////////////////

// 關於Login 頁面

/////////////////////////////////////////////////////////////////

判斷指定plist文件中是否有你想要的數據來彈出登陸頁面

(網上有這麼一段話：

window中不要添加多個subview，如想跳轉，請用UINavigationController的push方法push一個新的UIViewController，或者使用UIViewController的presentModelViewController方法來彈出一個新的頁面，注意此頁面會遮住下面的tab bar。 [UIWindow addSubview]的缺點：除了第一個被add進去的view以外，其餘由UIViewController控制的新添加view均沒法接收屏幕旋轉的delegate。第二，直接add一個subview視覺效果上是忽然頁面轉換成了另外一個界面，用戶體驗略差，並且也會擋住下面的tab bar，因爲view是被add到window中從而使window中第一個view被帶到了back，新的view則被帶到了front從而導致tab bar消失。

 

)

 

 

使用 presentModalViewController方法或許效果比pushview好點:

presentModalViewController:

[stationFunNav presentModalViewController:loginController animated:YES];

 

pushViewController:

        [stationFunNav pushViewController:loginController animated:YES];

 

 

還有是alertview的登陸彈出框（MAlertView是一個繼承UIAlerView的.h.m）

//設置登陸

        accountField = [[UITextField alloc]init];

        passwdField = [[UITextField alloc]init];

        //設置密碼框

        [passwdField setSecureTextEntry:YES];

        MAlertView *alertLogin = [[MAlertView alloc] initWithTitle:@"登陸" message:nil delegate:self cancelButtonTitle:@"肯定" otherButtonTitles:nil];

        [alertLogin addTextField:accountField placeHolder:@"這裏輸入用戶ID"];

        [alertLogin addTextField:passwdField placeHolder:@"這裏輸入密碼"];

        [alertLogin show];

 

 

 

presentModalViewController出來的頁面用dismissModalViewControllerAnimated來關閉

 

 

 

 

關於<libxml/tree.h>

在 bulid -> Header Search Paths 添加/usr/include/libxml2

 

 

代碼添加uibutton

UIButton* button = [UIButton buttonWithType:100];

    button.frame = CGRectMake(12,12,70,30);

    [button setTitle:@"考勤" forState:UIControlStateNormal];

    // 註冊按鈕按下時的處理函數

    [button addTarget:self action:@selector(countup:)

     forControlEvents:UIControlEventTouchUpInside];

    [self.view addSubview:button];

 

buttontype 能夠嘗試着用數字試試，（彷佛是私有api的寫法）

 

關於自定義的cell

在設置xib時，File’s Owner爲object , uitabviewcell 爲你自定義的class

引用的時候：

dateChooseCell = (DateSelectCell *)[tableView dequeueReusableCellWithIdentifier:@"DateSelectCell"];

 

    NSArray *nib = [[NSBundle mainBundle]loadNibNamed:@"DateSelectCell" owner:self options:nil];

        dateChooseCell = [nib objectAtIndex:0];

關閉鍵盤

 

    [tfldMedicineName resignFirstResponder];

得到焦點，打開鍵盤

    [txtUserID becomeFirstResponder];

 

增長動畫

#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];

 

//動畫結束時

- (void)animationDidStop:(CAAnimation *)theAnimation finished:(BOOL)flag{}

 

 

背景的漸變色（仍是用圖片吧..）

self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"bg.png"]];

 

 

iPhone開發中各類動畫翻頁效果整理

iphone中存在不少好看的動畫效果，用於頁面的切換等。其中某些是apple私有的，聽說私有的沒法經過apple的審批。 最近工做中恰好用到過其中的某些動畫，因此在網上搜了下資料，瞭解了下這些動畫。這裏就本身的理解作一下總結。

UIView 動畫

官方API中，使用UIView能夠設置5個動畫效果，分別爲：

UIViewAnimationTransitionNone    不使用動畫 UIViewAnimationTransitionFlipFromLeft    從左向右旋轉翻頁 UIViewAnimationTransitionFlipFromRight    從右向左旋轉翻頁，與UIViewAnimationTransitionFlipFromLeft相反 UIViewAnimationTransitionCurlUp    捲曲翻頁，從下往上 UIViewAnimationTransitionCurlDown    捲曲翻頁，從上往下

詳細請參見UIViewAnimationTransition，舉例以下：

[UIView beginAnimations:@"animationID" context:nil];//開始一個動畫塊，第一個參數爲動畫塊標識 [UIView setAnimationDuration:0.5f];//設置動畫的持續時間 [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; //設置動畫塊中的動畫屬性變化的曲線，此方法必須在beginAnimations方法和commitAnimations，默認即爲UIViewAnimationCurveEaseInOut效果。 //詳細請參見UIViewAnimationCurve [UIView setAnimationRepeatAutoreverses:NO];//設置是否自動反轉當前的動畫效果 [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft forView:self.view cache:YES]; //設置過渡的動畫效果，此處第一個參數可以使用上面5種動畫效果。 [self.view exchangeSubviewAtIndex:1 withSubviewAtIndex:0];//頁面翻轉 [UIView commitAnimations];//提交動畫

公共動畫效果

使用CATransiton能夠設置4種動畫效果，分別爲：

NSString * const kCATransitionFade;//漸漸消失 NSString * const kCATransitionMoveIn;//覆蓋進入 NSString * const kCATransitionPush;//推出 NSString * const kCATransitionReveal;//與MoveIn相反

舉例說明：

CATransition *animation = [CATransition animation]; animation.duration = 0.5f; animation.timingFunction = UIViewAnimationCurveEaseInOut;  animation.type = kCATransitionPush;//設置上面4種動畫效果 animation.subtype = kCATransitionFromTop;//設置動畫的方向，有四種，分別爲kCATransitionFromRight、kCATransitionFromLeft、kCATransitionFromTop、kCATransitionFromBottom  [self.view.layer addAnimation:animation forKey:@"animationID"];

私有動畫

iphone種還有不少動畫是蘋果私有的，例如刪除照片的動畫等， 私有動畫能夠直接在animation.type中傳入動畫的字符串便可。動畫有如下幾種：

cube：像立方體同樣翻轉 suckEffect：漸漸縮小，與刪除照片動畫同樣 oglFlip：上下旋轉，當subType爲fromLeft或者fromRight時，與UIViewAnimationTransitionFlipFromLeft和UIViewAnimationTransitionFlipFromRight同樣 rippleEffect:水波效果 pageCurl：與UIViewAnimationTransitionCurlUp同樣 pageUnCurl：與UIViewAnimationTransitionCurlDown同樣 cameraIrisHollowOpen：First half of cameraIris. cameraIrisHollowClose：Second half of cameraIris

以上全部動畫效果的demo請見http://www.cocoachina.com/bbs/read.php?tid-11820.html

UIViewAnimationState描述：http://www.iphonedevwiki.net/index.php/UIViewAnimationState

同時，本人在使用UIView實現suckEffect縮小的效果過程當中遇到一個問題（不知道如何定位），通過搜索終覓得解決方法，分享以下：

[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方法就是用於設置縮小點的位置的，此處雖然會報一個警告，可是結果仍是正確的。

 

關於軟鍵盤彈出時的上移

先設置textfield的delegate = self

 

- (void)textFieldDidBeginEditing:(UITextField *)textField 

{

//獲取這個textfield在tableview中的第幾行

//再更具第幾行設置頁面高度（暫時尚未找到很好的通用方法來改變高度，網上也有說textfield嵌套再tableview中時，是能夠自動調整頁面高度的，不知道怎麼設置）（前些天找到了，要繼承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;

    }

}
