1.申請APPKey

2.在AppDelegate.m文件中的代碼示例

#import "AppDelegate.h"
#import "WXApi.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
   
    [WXApi registerApp:@"申請的APPkey"];
    
    return YES;
}

3.具體的方法實現

#import "ViewController.h"
#import "WXApi.h"

@interface ViewController ()

@property (nonatomic, strong) UIButton *button;

@end

@implementation ViewController

- (void)viewDidLoad {
    
    [super viewDidLoad];
    
    self.button                 = [[UIButton alloc] initWithFrame:CGRectMake(100, 50, 100, 50)];
    self.button.backgroundColor = [UIColor blueColor];
    
    [self.button addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:self.button];
    
}


- (void)buttonClick:(UIButton *) button{

    NSLog(@"點擊");
    
    //創建發送對象實例
    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
    
    //創建分享內容對象
    WXMediaMessage *urlMessage = [WXMediaMessage message];
    urlMessage.title = @"我們";//分享標題
    urlMessage.description = @"大家一起過中秋";//分享描述
    [urlMessage setThumbImage:[UIImage imageNamed:@"test"]];//分享圖片,使用SDK的setThumbImage方法可壓縮圖片大小
    
    //創建多媒體對象
    WXWebpageObject *webObj = [WXWebpageObject object];
    webObj.webpageUrl = @"https://www.baidu.com";//分享鏈接
    
    //完成發送對象實例
    urlMessage.mediaObject = webObj;
    sendReq.message = urlMessage;
    
    //發送分享信息
    [WXApi sendReq:sendReq];
    
}
