iOS个人整理43-第三方开发平台的使用--环信、ShareSDK和科大讯飞

时间:2022-08-10 17:25:51

很多时候我们需要使用一些第三方平台提供的功能,当然自己也可以写,如果够牛逼。

一、环信

即时通信的第三方有很多,融云、Leancloud等,都可以帮助我们快速实现扣扣微信这样的即时聊天功能,以及附带的登录注册等功能。

环信怎么用:

1.这次开发者账号
2.创建应用
3.下载SDK,这里要注意,下载对应的平台和版本
4.导入SDK到工程,并根据要求导入相应的依赖库
5.配置工程,在Build Settings->Linking-> Other Link Flags中添加-Objc,如果-Objc冲突,则添加-force_load来解决

说的很简单,因为官方有详细的说明文档
http://docs.easemob.com/im/300iosclientintegration/20iossdkimport
讲的很明白,如果使用中有问题解决不了,可以找客服帮助

贴点代码,好歹说明我用过


//构造一个消息
-(void)makeMessage
{
//要发送的消息
EMTextMessageBody *body = [[EMTextMessageBody alloc]initWithText:_contentTextField.text];
//当前登录的账号
NSString *from = [[EMClient sharedClient]currentUsername];

//生成message ext 字典 传参数的
EMMessage *message = [[EMMessage alloc]initWithConversationID:_contactName from:from to:_contactName body:body ext:nil];

//设置消息类型
message.chatType = EMChatTypeChat;//单聊

//发送消息
[[EMClient sharedClient].chatManager asyncSendMessage:message progress:nil completion:^(EMMessage *message, EMError *error) {
if(error)
{
NSLog(@"发送消息失败 -- %d",error.code);
}
else
{
NSLog(@"发送消息成功");
[self.allDataMArray addObject:message];
//回到主线程
[self performSelectorOnMainThread:@selector(refreshUI) withObject:nil waitUntilDone:YES];
}
}];
}

#pragma mark -- 接收到消息
-(void)receiveMessage:(NSNotification*)notification
{
//取出消息们
NSArray *msgArray = notification.object;
for (EMMessage *itemMsg in msgArray) {
//判断消息是否为当前对话的消息
if ([itemMsg.from isEqualToString:self.contactName]) {
[_allDataMArray addObject:itemMsg];
}
}
//刷新
[_myTableView reloadData];
}

二、SharedSDK

http://www.mob.com/ 里面有很多有用的第三方功能,常用有SharedSDK可以第三方登录,还有一个短信验证的SDK,它还提供很多数据API,可以从上面取得需要的新闻、天气、菜谱等数据。

怎么注册账号,设置工程就不说了
如果我们要使用新浪微博的第三方登录,那么还需要去注册一个新浪微博的开发账号,创建应用,得到appkey。其他微信扣扣,也是一样的。
这个网站是[ShareSDK各社交平台申请APPkey 的网址及申请流程汇总]
http://bbs.mob.com/forum.php?mod=viewthread&tid=275&page=1&extra=#pid860


//基本配置
-(void)sharedSDKOptions{
//SharedSDK的appkey
[ShareSDK registerApp:@"113b8684926ce" activePlatforms:@[@(SSDKPlatformTypeSinaWeibo)] onImport:^(SSDKPlatformType platformType) {
switch (platformType)
{
// 新浪微博
case SSDKPlatformTypeSinaWeibo:
[ShareSDKConnector connectWeibo:[WeiboSDK class]];
break;

default:
break;
}
} onConfiguration:^(SSDKPlatformType platformType, NSMutableDictionary *appInfo) {
//设置新浪微博应用信息,其中authType设置为使用SSO+Web形式授权
//这些数据要注册新浪微博第三方
[appInfo SSDKSetupSinaWeiboByAppKey:@"2951738742"
appSecret:@"a7aef8a4b9f877472887bb740be8ab69"
redirectUri:@"http://www.sharesdk.cn"
authType:SSDKAuthTypeBoth];
}];
}

登录方法

//登录按钮
- (IBAction)loginAction:(id)sender {
//登录并得到用户信息
[ShareSDK getUserInfo:SSDKPlatformTypeSinaWeibo
onStateChanged:^(SSDKResponseState state, SSDKUser *user, NSError *error)
{
if (state == SSDKResponseStateSuccess)
{
//打印得到的用户信息
NSLog(@"uid=%@",user.uid);
NSLog(@"%@",user.credential);
NSLog(@"token=%@",user.credential.token);
NSLog(@"nickname=%@",user.nickname);
}
else
{
NSLog(@"%@",error);
}
}];
}

三、科大讯飞

科大讯飞提供了各种语音功能,主要两种,语音转文字,文字转语音,这种功能我们自己肯定写不出来。
注册等准备工程都是一样的,官方文档也有说明

贴个语音识别成文字的代码


#import "RootViewController.h"
#import <iflyMSC/IFlyRecognizerViewDelegate.h>
#import <iflyMSC/IFlyRecognizerView.h>
#import <iflyMSC/IFlySpeechConstant.h>
#import <iflyMSC/IFlySpeechError.h>
#import "SecondViewController.h"

@interface RootViewController ()<IFlyRecognizerViewDelegate>

@property (nonatomic,retain)UITextView *myTextView;//用来显示文字
@property (nonatomic,retain)UIButton *myBtn;//开始录音识别
@property (nonatomic,retain)IFlyRecognizerView *myRecognizerView;//讯飞提供的录音界面

@end

@implementation RootViewController

//懒加载
-(UITextView *)myTextView
{
if (!_myTextView) {
_myTextView = [[UITextView alloc]initWithFrame:CGRectMake(0, 60, CGRectGetWidth(self.view.bounds), 200)];
}
return _myTextView;
}
-(UIButton *)myBtn
{
if (!_myBtn) {
_myBtn = [UIButton buttonWithType:UIButtonTypeSystem];
_myBtn.frame = CGRectMake(100, 340, 100, 50);
[_myBtn setTitle:@"开始录音" forState:UIControlStateNormal];
[_myBtn addTarget:self action:@selector(startReAction) forControlEvents:UIControlEventTouchUpInside];
}
return _myBtn;
}

-(IFlyRecognizerView *)myRecognizerView
{
if (!_myRecognizerView) {
_myRecognizerView = [[IFlyRecognizerView alloc]initWithCenter:self.view.center];
_myRecognizerView.delegate = self;
//设置应用领域
[_myRecognizerView setParameter: @"iat" forKey: [IFlySpeechConstant IFLY_DOMAIN]];
//设置录音文件保存路径
[_myRecognizerView setParameter:@"asrview.pcm" forKey:[IFlySpeechConstant ASR_AUDIO_PATH]];
//启动识别服务
// [_myRecognizerView start];
}
return _myRecognizerView;
}

//实现按钮的回调方法
-(void)startReAction
{
if (self.myRecognizerView) {
//如果存在,先取消
[self.myRecognizerView cancel];
// [self.myRecognizerView removeFromSuperview];//不用手动
[self.view addSubview:self.myRecognizerView];
//开始录音
[self.myRecognizerView start];
}
else
{
NSLog(@"myRecognizer 懒加载有问题");
}
}

#pragma mark -- 识别语音带界面的代理方法

//识别结果的返回
-(void)onResult:(NSArray *)resultArray isLast:(BOOL)isLast
{
//声明可变字符串,用来拼接所有的key
NSMutableString *keyString = [[NSMutableString alloc]init];
//从数组中取出字典
NSDictionary *dic_fromResults = resultArray.firstObject;
//拼接key
for (NSString *key in dic_fromResults) {
[keyString appendString:key];
}
//从拼接好的keyString中取出我们所需要的文字
NSString * resultFromJson = [self stringFromJson:keyString];
if (self.myTextView.text) {
//说明有文字
self.myTextView.text = [NSString stringWithFormat:@"%@%@",self.myTextView.text,resultFromJson];
}
else
{
self.myTextView.text = @"没有文字";
}

NSLog(@"array - %@",resultArray);
}

- (void)viewDidLoad {
[super viewDidLoad];

[self.view addSubview:self.myBtn];
[self.view addSubview:self.myTextView];

self.view.backgroundColor = [UIColor colorWithRed:109/255.0 green:211/255.0 blue:206/255.0 alpha:1];
}

/**
语音识别返回的数据是json格式
解析听写json格式的数据
params例如:
{"sn":1,"ls":true,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"w":"白日","sc":0}]},{"bg":0,"cw":[{"w":"依山","sc":0}]},{"bg":0,"cw":[{"w":"尽","sc":0}]},{"bg":0,"cw":[{"w":"黄河入海流","sc":0}]},{"bg":0,"cw":[{"w":"。","sc":0}]}]}
****/

- (NSString *)stringFromJson:(NSString*)params
{
if (params == NULL) {
return nil;
}

NSMutableString *tempStr = [[NSMutableString alloc] init];
NSDictionary *resultDic = [NSJSONSerialization JSONObjectWithData: //返回的格式必须为utf8的,否则发生未知错误
[params dataUsingEncoding:NSUTF8StringEncoding] options:kNilOptions error:nil];

if (resultDic!= nil) {
NSArray *wordArray = [resultDic objectForKey:@"ws"];

for (int i = 0; i < [wordArray count]; i++) {
NSDictionary *wsDic = [wordArray objectAtIndex: i];
NSArray *cwArray = [wsDic objectForKey:@"cw"];

for (int j = 0; j < [cwArray count]; j++) {
NSDictionary *wDic = [cwArray objectAtIndex:j];
NSString *str = [wDic objectForKey:@"w"];
[tempStr appendString: str];
}
}
}
return tempStr;
}
