准备工作---原文来自这个
首先要在微信开放平台申请 AppID（我第一天晚上申请的，第二天中午就通过了），接着导入 SDK，也就是3个 .h 和一个 .a 文件，详情见这里
如果你是 copy 在自建 group 里面，
1.需要在 Build Phases - Link Binary With Libraries 里面 .a 文件
2.在 Copy Bundle Resources add .h 文件
3.在 Bulid Settings - Library Search Paths "+" sdk 路径
如果 copy 在自带 group 里面，则不需要，已经自动配置好
AppDelegate.h ,import "WXApi.h" 和 遵守协议
#import <UIKit/UIKit.h> #import "WXApi.h" @interface AppDelegate : UIResponder <UIApplicationDelegate,WXApiDelegate> @property (strong, nonatomic) UIWindow *window; @end
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //申请的 AppID [WXApi registerApp:@"wxxxxx"]; return YES; } //重写 handleOpenURL -(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{ return [WXApi handleOpenURL:url delegate:self]; } //重写 openURL -(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options{ return [WXApi handleOpenURL:url delegate:self]; }
在你需要引用的类里面
#import "ViewController.h" #import "WXApi.h" @interface ViewController () @property (nonatomic,strong)UIButton *button; @end @implementation ViewController static NSString *KLinkURL = @"http://www.iqiyi.com/a_19rrhbkfv1.html?vfm=2008_aldbd"; static NSString *KLinkTagName = @"WECHAT_TAG_JUMP_SHOWRANK"; static NSString *KLinkTitle = @"史上最帅男人"; static NSString *KLinkDescription = @"妈呀，谁都别拦我，我要嫁给他！！！！！！！！"; - (void)viewDidLoad { [super viewDidLoad]; [self.view addSubview:self.button]; } -(void)Click{ //创建发送对象实例 SendMessageToWXReq *sendReq = [[SendMessageToWXReq alloc] init]; sendReq.bText = NO;//不使用文本信息 sendReq.scene = 0;//0 = 好友列表 1 = 朋友圈 2 = 收藏 //创建分享内容对象 WXMediaMessage *urlMessage = [WXMediaMessage message]; urlMessage.title = KLinkTitle;//分享标题 urlMessage.description = KLinkDescription;//分享描述 [urlMessage setThumbImage:[UIImage imageNamed:@"sb2.jpg"]];//分享图片,使用SDK的setThumbImage方法可压缩图片大小,图片大小不能超过 32 KB //创建多媒体对象 WXWebpageObject *webObj = [WXWebpageObject object]; webObj.webpageUrl = KLinkURL;//分享链接 //完成发送对象实例 urlMessage.mediaObject = webObj; sendReq.message = urlMessage; //发送分享信息 [WXApi sendReq:sendReq]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } -(UIButton *)button{ if (!_button) { _button = [[UIButton alloc]init]; _button.frame = CGRectMake(100, 100, 100, 100); _button.backgroundColor = [UIColor redColor]; [_button addTarget:self action:@selector(Click) forControlEvents:UIControlEventTouchUpInside]; } return _button; }
