为了方便使用，我封装了一个分享的工具类LFSystemShareUtil。工程要引Social.framework。
LFSystemShareUtil.h
#import <Foundation/Foundation.h>
#import <Social/Social.h> typedef NS_ENUM(NSInteger, LFSystemShareType) {
LFSystemShareWeChat,//微信
LFSystemShareQQ,//腾讯QQ
LFSystemShareSina,//新浪微博
}; typedef NS_ENUM(NSInteger, LFSystemShareState) {
LFSystemShareStateCancel,//取消
LFSystemShareStateDone,//完成
LFSystemShareStateNone,//未安装
}; @interface LFSystemShareUtil : NSObject /**
直接分享到某平台 @param type 平台
@param controller 弹出分享界面的控制器
@param items 可以仅分享图@[UIImage]，可以放多张；或者仅分享纯视频、音乐@[NSURL]；或者一个带文字和缩略图的网页@[NSURL,NSString,UIImage]，等等，总之把要分享的东西放到数组即可
@param shareResult LFSystemShareState
*/
+ (void)shareWithType:(LFSystemShareType)type controller:(UIViewController *)controller andItems:(NSArray *)items completionHandler:(void(^)(LFSystemShareState state))shareResult; /**
