IOS开发之分享

　　在我们IOS软件开发当中我们有事需要分享一些图片视屏和文档之类的东西。但是有可能用的是别的软件，这时候我们就需要学习分享。

我们举个分享微信的例子好了：

看代码

先看AppDelegate.m文件内容

在AppDelegate.m里面我们需要

[WXApi registerApp:@"wx252e7c172102f9cb" withDescription:@"微信分享 1.0"];
才能够分享微信

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {// Override point for customization after application launch./*只有写了这一句话才能够在具体的地方实现分享功能wx252e7c172102f9cb 这个项目向微信注册的开发者账号微信分享 1.0*/[WXApi registerApp:@"wx252e7c172102f9cb" withDescription:@"微信分享 1.0"];self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];ViewController * tempVC = [[ViewController alloc] init];self.window.rootViewController = tempVC;[self.window makeKeyAndVisible];return YES;
}

再看控制器

.h文件

#import <UIKit/UIKit.h>@interface ViewController : UIViewController@property(nonatomic, strong) UIButton *wechatFriendBtn;
@property(nonatomic, strong) UIButton *wechatFriendsBtn;@end

.m文件

#import "ViewController.h"
#import "WXApi.h"@interface ViewController ()@end#define kLoadImage(name, type) [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:name ofType:type]]
#define ScreenWidth self.view.frame.size.width

{[super viewDidLoad];_wechatFriendBtn = [UIButton buttonWithType:UIButtonTypeCustom];_wechatFriendBtn.frame = CGRectMake(ScreenWidth / 2 - 120, ScreenHeight / 2 - 120, 80, 80);[_wechatFriendBtn setShowsTouchWhenHighlighted:YES];[_wechatFriendBtn setBackgroundImage:kLoadImage(@"btn_微信好友", @"png") forState:UIControlStateNormal];_wechatFriendBtn.enabled = YES;_wechatFriendBtn.tag = 1;[_wechatFriendBtn addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];[self.view addSubview:_wechatFriendBtn];_wechatFriendsBtn = [UIButton buttonWithType:UIButtonTypeCustom];_wechatFriendsBtn.frame = CGRectMake(ScreenWidth / 2 + 40, ScreenHeight / 2 - 120, 80, 80);[_wechatFriendsBtn setShowsTouchWhenHighlighted:YES];[_wechatFriendsBtn setBackgroundImage:kLoadImage(@"btn_朋友圈", @"png") forState:UIControlStateNormal];_wechatFriendsBtn.tag = 2;[_wechatFriendsBtn addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];[self.view addSubview:_wechatFriendsBtn];}-(void)btnClicked:(UIButton *)btn
{switch (btn.tag){case 1:{//这种分享是带文字和图片的分享，属于网页分享，注意分享的图片大小不能超过32k。WXMediaMessage *message = [WXMediaMessage message];//分享内容的标题message.title = @"分享的标题";//分享内容的描述message.description = @"分享的介绍";//分享的图片[message setThumbImage:kLoadImage(@"share", @"png")];//分享链接WXWebpageObject *ext = [WXWebpageObject object];ext.webpageUrl = @"www.sougou.com";message.mediaObject = ext;SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];/*发送消息的类型，包括文本消息和多媒体消息两种，两者只能选择其一，不能同时发送文本和多媒体消息*/req.bText = NO;req.message = message;//这个属性表示分享到好友req.scene = WXSceneSession;[WXApi sendReq:req];//这种分享的是纯文字的信息。//            SendMessageToWXReq* req = [[SendMessageToWXReq alloc] init];//            req.text = _linkStr;//            req.bText = YES;//            req.scene = WXSceneSession;//            [WXApi sendReq:req];

        }break;}
