小贴士:记住要科学上网才能访问他们的官网.

推荐科学上网<shadowrocks>

官方文档 https://developers.line.me/en/
集成文档 https://developers.line.me/en/docs/ios-sdk/integrate-line-login/

温馨提示:在官方先要创建app应用, 1.获取Channel ID， 2.绑定iOS bundle ID

一、UI

二、项目-系统依赖库

系统依赖库

三、info.plist

info.plist配置

四、code

AppDelegate.m

#import "AppDelegate.h"
#import <LineSDK/LineSDK.h>

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    return YES;
}
// 本应用打开第三方应用
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options
{
    return [[LineSDKLogin sharedInstance] handleOpenURL:url];
}

ViewController.m

#import "ViewController.h"
#import <LineSDK/LineSDK.h>

@interface ViewController ()<LineSDKLoginDelegate>
@property (weak, nonatomic) IBOutlet UITextView *tv_content;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [LineSDKLogin sharedInstance].delegate = self; // 设置代理
}

- (IBAction)LineLogin:(UIButton *)sender {
     [[LineSDKLogin sharedInstance] startLogin]; // 使用line登录
}
// line登录返回的授权信息
- (void)didLogin:(LineSDKLogin *)login
      credential:(LineSDKCredential *)credential
         profile:(LineSDKProfile *)profile
           error:(NSError *)error
{
    if (error) {
        // Login failed with an error. Use the error parameter to identify the problem.
        NSLog(@"Error: %@", error.localizedDescription);
    }
    else {
        
        // Login success. Extracts the access token, user profile ID, display name, status message, and profile picture.
        NSString * accessToken = credential.accessToken.accessToken;
        NSString * userID = profile.userID;
        NSString * displayName = profile.displayName;
        NSString * statusMessage = profile.statusMessage;
        NSURL * pictureURL = profile.pictureURL;
        NSLog(@"accessToken: %@", accessToken); // 访问令牌
        NSLog(@"userID: %@", userID);           // 用户id
        NSLog(@"displayName: %@", displayName); // 用户昵称
        NSLog(@"statusMessage: %@", statusMessage);
        NSLog(@"pictureURL: %@", pictureURL); // 头像
        NSString *authMsg = [NSString stringWithFormat:@"授权返回的信息:accessToken: %@,userID: %@,displayName: %@,statusMessage: %@,pictureURL: %@",accessToken,userID,displayName,statusMessage,pictureURL];
        
        self.tv_content.text = authMsg;
        
        
        NSString * pictureUrlString;
        
        // If the user does not have a profile picture set, pictureURL will be nil
        if (pictureURL) {
            pictureUrlString = profile.pictureURL.absoluteString;
        }
        
    }
}

集成步骤说明
核心代码每个步骤在下面了

参考
 https://developers.line.me/en/docs/ios-sdk/integrate-line-login/
    记得是line login应用
 1.配置info.plist
    ChannelID
    LSApplicationQueriesSchemes(白名单)
 2.添加系统需要依赖的库
 3.处理调用第三方应用
     - (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary *)options
     {
     return [[LineSDKLogin sharedInstance] handleOpenURL:url];
     }
 
 
 
 4.在登录界面处理
    3.1 设置代理 [LineSDKLogin sharedInstance].delegate = self;
    3.3 按钮点击 触发line的登录 [[LineSDKLogin sharedInstance] startLogin];
    3.2 监听login代理
        code
 - (void)didLogin:(LineSDKLogin *)login
 credential:(LineSDKCredential *)credential
 profile:(LineSDKProfile *)profile
 error:(NSError *)error
 {
         if (error) {
         // Login failed with an error. Use the error parameter to identify the problem.
         NSLog(@"Error: %@", error.localizedDescription);
         }
         else {
 
         // Login success. Extracts the access token, user profile ID, display name, status message, and profile picture.
         NSString * accessToken = credential.accessToken.accessToken;
         NSString * userID = profile.userID;
         NSString * displayName = profile.displayName;
         NSString * statusMessage = profile.statusMessage;
         NSURL * pictureURL = profile.pictureURL;
         NSLog(@"accessToken: %@", accessToken); // 访问令牌
         NSLog(@"userID: %@", userID);           // 用户id
         NSLog(@"displayName: %@", displayName); // 用户昵称
         NSLog(@"statusMessage: %@", statusMessage);
         NSLog(@"pictureURL: %@", pictureURL); // 头像
         NSString *authMsg = [NSString stringWithFormat:@"授权返回的信息:accessToken: %@,userID: %@,displayName: %@,statusMessage: %@,pictureURL: %@",accessToken,userID,displayName,statusMessage,pictureURL];
 
         self.tv_content.text = authMsg;
 
 
         NSString * pictureUrlString;
 
         // If the user does not have a profile picture set, pictureURL will be nil
         if (pictureURL) {
            pictureUrlString = profile.pictureURL.absoluteString;
         }
 
         }
 }
