Facebook/Twitter/LINEへ投稿する「DCSocial」クラス (iOS 7対応版)

Facebook/Twitter/LINEへの「画像・テキスト・URL」の投稿をシンプルな記述で実行する「DCSocial」クラスを iOS 7に最適化しました。

このクラスを使用する際は「Social」フレームワークが必要になります。

主な機能は下記の5個です。今後随時更新して行きます。

主な機能

Facebookへの画像/テキスト/URLの投稿
Twitterへの画像/テキスト/URLの投稿
LINEへの画像投稿
LINEへテキスト投稿
メール/Twitter/Facebookに共有

下記よりサンプルとソースコードのダウンロードが行えます。

LINEへの JPEG画像投稿

typedef NS_ENUM(NSUInteger, imageExtId) {
    JPEG = 0,
    PNG  = 1
};

[DCSocial postImageToLine:POST_IMG_NAME imageType:JPEG];

LINEへの PNG画像投稿

typedef NS_ENUM(NSUInteger, imageExtId) {
    JPEG = 0,
    PNG  = 1
};

[DCSocial postImageToLine:POST_IMG_NAME imageType:PNG];

LINEへテキスト投稿

[DCSocial postTextToLine:POST_TEXT];

メール/Twitter/Facebook共有

[DCSocial socialShare:self shareText:POST_TEXT shareImage:[UIImage imageNamed:POST_IMG_NAME]];
