汉语字典

项目三:汉语字典
总结:
一：开机画面的加载进度条
在AppDelegate的

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

中铺一张和LaunchScreen一样的ImageView,然后让进度条做动画。
进度条下面的数字变化，使用计时器，是它改变label.text的值。

关键代码:

[NSTimer scheduledTimerWithTimeInterval:0.1 target:self selector:@selector(changeAction:) userInfo:nil repeats:YES];

-(void)changeAction:(NSTimer *)sender{    time += 0.05;    if (time <= 1.05)    {        NSString *string = [NSString stringWithFormat:@"%.0f",time*100];        label.text = [string stringByAppendingString:@"%"];    }    NSString *string = [NSString stringWithFormat:@"%.0f",time*100];    if ([string isEqualToString:@"125"])    {        [sender invalidate];        imageView.hidden = YES ;    }}

二、最近搜索
要数据持久化，搜索的数据放在tmp目录下的文件中
关键代码:

    //tmp    NSString *tmp = NSTemporaryDirectory();    NSString *path = [tmp stringByAppendingPathComponent:@"RecentlySearch"];    NSFileManager *manager = [[NSFileManager alloc]init];    if (![manager fileExistsAtPath:path])    {        [manager createDirectoryAtPath:path withIntermediateDirectories:YES attributes:nil error:nil];    }    else    {//        NSLog(@"存在");    }

三、部首检索和拼音检索
这个页面是一个UITableView,里面的用可变数组dataSource装的数据是从SQLITE数据库中读取的。
数据读取方法参考: AlphabelModel.m文件中的+(NSArray*)find;方法。

四、朗读功能

//导入头文件，#import <AVFoundation/AVFoundation.h>

调用系统API 。此处应开辟一个子线程然后在调用朗读的方法，否则若让它在主线程中执行，则会卡UI 。

- (IBAction)soundAction:(UIButton *)sender {    NSBlockOperation *blockOperation = [NSBlockOperation blockOperationWithBlock:^{        [[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:Nil];        AVSpeechSynthesizer *syner = [[AVSpeechSynthesizer alloc] init];        AVSpeechUtterance *utter = [[AVSpeechUtterance alloc] initWithString:self.simpLabel.text];        float rate = AVSpeechUtteranceMinimumSpeechRate;        [utter setRate:rate];        [utter setVoice:[AVSpeechSynthesisVoice voiceWithLanguage:[AVSpeechSynthesisVoice currentLanguageCode]]];        [syner speakUtterance:utter];    }];    [queue addOperation:blockOperation];}

XIB如下:

五、汉字详细介绍页面
1、复制功能:复制当前页面的米字格内的汉字
主要代码:

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];pasteboard.string = self.titleString ;

2.收藏功能:
把当前的页面的字、拼音、部首、笔画写入tmp目录下的文档中，进行数据持久化。

3.分享功能:
分享功能有四中分享，分别是微博、QQ、QQ空间、微信分享
使用COCOPOD导入微博、QQ、微信的第三方

//微信 pod ‘libWeChatSDK’, ‘~> 1.5’ //腾讯 pod ‘TencentOpenApiSDK’, ‘~> 2.9.0’ //微博 pod “WeiboSDK”

在AppDelegate.m文件中

//导入头文件:#import <WeiboSDK.h>#import <TencentOpenAPI/TencentOAuth.h>#import <WXApi.h>

关键代码:

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {//    [WeiboSDK enableDebugMode:YES];    [WeiboSDK registerApp:kAppKey];    //    TencentOAuth *_tencentOAuth = [[TencentOAuth alloc]initWithAppId:Tencent_AppID andDelegate:nil];//    [WXApi registerApp:WX_AppID];      return YES;}-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{    return [TencentOAuth HandleOpenURL:url];    return [WeiboSDK handleOpenURL:url delegate:nil];    return [WXApi handleOpenURL:url delegate:self];}-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{    return [TencentOAuth HandleOpenURL:url];    return [WeiboSDK handleOpenURL:url                          delegate:nil];    return [WXApi handleOpenURL:url delegate:self];}//微信-(void) onReq:(BaseReq*)req{    if([req isKindOfClass:[GetMessageFromWXReq class]])    {        // 微信请求App提供内容， 需要app提供内容后使用sendRsp返回        NSString *strTitle = [NSString stringWithFormat:@"微信请求App提供内容"];        NSString *strMsg = @"微信请求App提供内容，App要调用sendResp:GetMessageFromWXResp返回给微信";        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];        alert.tag = 1000;        [alert show];//        [alert release];    }    else if([req isKindOfClass:[ShowMessageFromWXReq class]])    {        ShowMessageFromWXReq* temp = (ShowMessageFromWXReq*)req;        WXMediaMessage *msg = temp.message;        //显示微信传过来的内容        WXAppExtendObject *obj = msg.mediaObject;        NSString *strTitle = [NSString stringWithFormat:@"微信请求App显示内容"];        NSString *strMsg = [NSString stringWithFormat:@"标题：%@ \n内容：%@ \n附带信息：%@ \n缩略图:%lu bytes\n\n", msg.title, msg.description, obj.extInfo, msg.thumbData.length];        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];        [alert show];//        [alert release];    }    else if([req isKindOfClass:[LaunchFromWXReq class]])    {        //从微信启动App        NSString *strTitle = [NSString stringWithFormat:@"从微信启动"];        NSString *strMsg = @"这是从微信启动的消息";        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];        [alert show];//        [alert release];    }}//微信-(void) onResp:(BaseResp*)resp{    if([resp isKindOfClass:[SendMessageToWXResp class]])    {        NSString *strTitle = [NSString stringWithFormat:@"发送媒体消息结果"];        NSString *strMsg = [NSString stringWithFormat:@"errcode:%d", resp.errCode];        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:strTitle message:strMsg delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];        [alert show];//        [alert release];    }}

微博分享

//微博分享    WBMessageObject *message = [WBMessageObject message];    WBImageObject *wbImageObject = [WBImageObject object];    wbImageObject.imageData = [NSData dataWithContentsOfFile:shareFilePath];    message.imageObject = wbImageObject ;    WBSendMessageToWeiboRequest *request = [WBSendMessageToWeiboRequest requestWithMessage:message];    [WeiboSDK sendRequest:request];

qq分享

//qq分享//开发者分享图片数据    NSData *imgData = [NSData dataWithContentsOfFile:shareFilePath];    //    QQApiImageObject *imgObj = [QQApiImageObject objectWithData:imgData                                               previewImageData:imgData                                                          title:@"学霸汉语词典"                                                    description:nil];    SendMessageToQQReq *req = [SendMessageToQQReq reqWithContent:imgObj];    //将内容分享到qq    [QQApiInterface sendReq:req];

qq空间分享

//qq空间分享//开发者分享图片数据    NSData *imgData = [NSData dataWithContentsOfFile:shareFilePath];    //    QQApiImageObject *imgObj = [QQApiImageObject objectWithData:imgData                                               previewImageData:imgData                                                          title:@" 学霸汉语词典 "                                                    description:nil];    SendMessageToQQReq *req = [SendMessageToQQReq reqWithContent:imgObj];    //将内容分享到qq    [QQApiInterface sendReq:req];

微信分享

//微信分享//    NSLog(@"weixinShare");    //微信朋友圈分享    WXMediaMessage *message = [WXMediaMessage message];    WXImageObject *wxImageObject = [WXImageObject object];    wxImageObject.imageData = [NSData dataWithContentsOfFile:shareFilePath];    message.mediaObject = wxImageObject ;    SendMessageToWXReq *sendMessageToWXReq = [[SendMessageToWXReq alloc]init];    sendMessageToWXReq.scene = 1;    sendMessageToWXReq.bText = NO ;    sendMessageToWXReq.message = message ;    [WXApi sendReq:sendMessageToWXReq];

XIB如下:

七、毛玻璃的使用

//毛玻璃的使用FXBlurView *fxblurView = [[FXBlurView alloc]initWithFrame:CGRectMake(0,0, Screen_Width, Screen_Height)];    fxblurView.dynamic = NO;    fxblurView.blurRadius = 40;    fxblurView.tintColor = [UIColor clearColor];    [self.view addSubview:fxblurView];

八、获取当前页面的截图

 UIGraphicsBeginImageContext(self.view.bounds.size);     //currentView 当前的view  创建一个基于位图的图形上下文并指定大小为                [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];//renderInContext呈现接受者及其子范围到指定的上下文                viewImage = UIGraphicsGetImageFromCurrentImageContext();//返回一个基于当前图形上下文的图片                UIGraphicsEndImageContext();//移除栈顶的基于当前位图的图形上下文                UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);//然后将该图片保存到图片图                NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);                NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:[NSString stringWithFormat:@"sms.gif"]];   // 保存文件的名称                BOOL result = [UIImagePNGRepresentation(viewImage)writeToFile: filePath    atomically:YES]; // 保存成功会返回YES

九、第三方的导入
使用cocoPod导入

platform :ios, '7.0'pod "AFNetworking", "~> 2.5"pod 'SDWebImage'pod 'MJRefresh'pod 'FMDB'pod "WeiboSDK", :git => "https://github.com/sinaweibosdk/weibo_ios_sdk.git"pod 'FXBlurView','~>1.6.3'pod 'libWeChatSDK', '~> 1.5'pod 'TencentOpenApiSDK', '~> 2.9.0'
