iOS App share with Google Plus

前言

Google Plus的分享功能要加到iOS專案裡面不會太困難.

官方網站的原文教學

環境設定

下載Google+ iOS SDK (official link)

檢查一下

AssetsLibrary.framework

Foundation.framework

CoreLocation.framework

CoreMotion.framework

CoreGraphics.framework

CoreText.framework

MediaPlayer.framework

Security.framework

SystemConfiguration.framework

UIKit.framework

並從下載回來的Google+ iOS SDK資料夾內

拖曳&import

GooglePlus.framework

GoogleOpenSource.framework

---

建立一個API project

1. 前往Google API Console

舊版的設定頁面

---

註冊一個app

---

完成後應該長得像這樣

---

新版的設定頁面

啟用Google+API

---

註冊一個app

---

填寫必要資訊

---

完成後應該長得像這樣

程式

在AppDelegate.m

#import 
#import  
static NSString * const kClientID = @"blahblahblah.apps.googleusercontent.com";

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Set app's client ID for |GPPSignIn| and |GPPShare|.
    [GPPSignIn sharedInstance].clientID = kClientID;
    ...
}

在ViewController.m

@interface YourViewController ()  {
     ...
- (void)viewDidLoad {
     [super viewDidLoad];
     [GPPShare sharedInstance].delegate = self;
}
     ...
- (void)gplusBtnPressed:(id)sender {   
    id shareBuilder = [[GPPShare sharedInstance] shareDialog];
   
    // This line will fill out the title, description, and thumbnail of the item
    // you're sharing based on the URL you included.
    //[shareBuilder setURLToShare:[NSURL URLWithString:@"The url you want to share"]];
    [shareBuilder setContentDeepLinkID:@"DeepLinkID"];
    [shareBuilder setTitle:@" 標題 "
               description:@" 描述"]
              thumbnailURL:[NSURL URLWithString:[@"縮圖網址"]]];

    [shareBuilder setPrefillText:msg];
    [shareBuilder open];
}

#pragma mark - GPPShareDelegate
- (void)finishedSharing:(BOOL)shared {
   
}

- (void)reportAuthStatus {
    if ([GPPSignIn sharedInstance].authentication) {
        NSLog(@"Status: Authenticated");
    } else {
        // To authenticate, use Google+ sign-in button.
        NSLog(@"Status: Not authenticated");
    }
}

如果分享時發生Error 404 Not Found, 那最有可能就是client ID沒有符合

希望大家都分享順利囉~
