前情：最近老项目需要添加微信分享的功能，因为是老项目所以是OC编写的。所以这里分享下开发微信分享的一个流程。
1:首先需要在微信开放平台注册你的应用：open.weixin.qq.com
2:OK 你注册成功后需要用到的是 appid 以及 你注册应用时自己填写的 Universal Links。好的，都获取到了，那我们开始项目代码中的配置
（1）：首先用cocoapods 终端引入我们需要的库：
pod 'WechatOpenSDK'
（2）：配置info.plist 文件：
编辑
(3)：
《1》：在AppDelegate.h 中引入 这里是我的 AppDelegate.h 内容
#import <UIKit/UIKit.h>
#import "WXApi.h"
//下方这里是用协议代理方法实现的一个分享状态的回调(你也可以用block方式实现，block相对好用些)
@protocol WXAuthDelegate
@optional
-(void)wxShareSuccessd:(NSString *)Type;
@end
//
@interface AppDelegate : UIResponder
@property (nonatomic, assign) id delegate;
@end
《2》：这里是AppDelegate.m 中的内容（这里不全粘贴了 我将有用的挑出来 你可以直接粘贴到你的
.m文件中）：
首相需要 注册你的app
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//向微信注册
[WXApi registerApp:@"wx689eeb576a727467" universalLink:@"https://tfpt_teacher/app/"];
return YES;
}
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {
return[WXApi handleOpenURL:url delegate:self];
}
- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
return [WXApi handleOpenURL:url delegate:self];
}
//这里是微信库里的方法的回调
-(void) onResp:(BaseResp*)resp{
if([resp isKindOfClass:[SendMessageToWXResp class]]) //判断这里是分享功能
{
NSString *strTitle = [NSString stringWithFormat:@"提示"];
NSString *strMsg;
if (resp.errCode == 0) {
//成功
if (self.delegate && [self.delegate respondsToSelector: @selector(wxShareSuccessd:)])
[self.delegate wxShareSuccessd:@"0"];
strMsg = [NSString stringWithFormat:@"分享成功"];
}else if (resp.errCode == -2){
//取消 分享
if (self.delegate && [self.delegate respondsToSelector: @selector(wxShareSuccessd:)])
[self.delegate wxShareSuccessd:@"-2"];
strMsg = [NSString stringWithFormat:@"取消分享"];
}else{
//失败
if (self.delegate && [self.delegate respondsToSelector: @selector(wxShareSuccessd:)])
[self.delegate wxShareSuccessd:@"-1"];
strMsg = [NSString stringWithFormat:@"分享失败,请重试"];
}
}else{
//微信其他功能 如登录等的判断
}
}
（4）：接下来是在你要实现点击分享的界面里：
例如我这的是LJFMainVC里
#import "LJFMainVC.h"
#import "AppDelegate.h" //引入AppDelegate.h
#import "ShareKindView.h" //我自己封装的用于分享的view 具体分享的设置在这里面，下面会贴出实现代码 ，你复制到你项目的时候 图标会不显示，请你自己添加图标。
@interface LJFMainVC () //遵守协议
//点击分享按钮 弹出选择分享微信好友 还是 朋友圈
-(void)shareClick{
if (self.ShareKindV == nil) {
self.ShareKindV = [[ShareKindView alloc]initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)];
}
self.ShareKindV.shareTitle = @" ***";
self.ShareKindV.shareDescripTion = @"*** ";
self.ShareKindV.sharePath = [NSString stringWithFormat:@"***"];
self.ShareKindV.ShareImageNameStr = @"share微信.png";
//下面这里是如引用，防止内存泄露
__weak __typeof(self) weakSelf = self;
self.ShareKindV.failOpenWXBlock = ^{
[weakSelf.view makeToast:@"请安装微信后重试!"];
};
[self.tabBarController.view addSubview:self.ShareKindV];
}
//这里是实现代理方法 成功的消息会从 appdelegate.m 的协议方法中传到这
-(void)wxShareSuccessd:(NSString *)Type{
if ([Type isEqualToString:@"0"]) {
//分享成功的处理
}else{
//分享失败的处理
}
}
(4):那么下面就是分享界面的封装了直接粘贴代码吧 （你可复制使用）
这里是 .h 文件
#import <UIKit/UIKit.h>
#import "WXApi.h"
NS_ASSUME_NONNULL_BEGIN
@interface ShareKindView : UIView
@property (nonatomic,strong) NSString * ShareImageNameStr;
@property (nonatomic,strong) NSString * sharePath;
@property (nonatomic,strong) NSString * shareTitle;
@property (nonatomic,strong) NSString * shareDescripTion;
@property (nonatomic,copy) void(^failOpenWXBlock)(void);
@end
NS_ASSUME_NONNULL_END
下面这里是.m文件
#import "ShareKindView.h"
@implementation ShareKindView
-(id)initWithFrame:(CGRect)frame{
self = [super initWithFrame:frame];
if (self) {
self.backgroundColor = [UIColor colorWithWhite:0.3 alpha:0.7];
[self presetUI];
}
return self;
}
-(void)presetUI{
UIView * BottomPickView = [[UIView alloc]initWithFrame:CGRectMake(0, SCREEN_HEIGHT-190,SCREEN_WIDTH, 190)];
BottomPickView.backgroundColor = COLOR_WITH_HEX(0xF8F8F7);
[self addSubview:BottomPickView];
[CYtools yp_setCornerRadiusWithView:BottomPickView radius:20 positions:@[@1,@2]];
UILabel * titlelbale = [[UILabel alloc]initWithFrame:CGRectMake(0, 20, 200, 40)];
[titlelbale setCenterX:SCREEN_WIDTH/2];
titlelbale.text = @"分享到";
titlelbale.textColor = COLOR_WITH_HEX(0x222222);
titlelbale.font = [UIFont systemFontOfSize:17 weight:UIFontWeightMedium];
titlelbale.textAlignment = NSTextAlignmentCenter;
[BottomPickView addSubview:titlelbale];
for (int i = 0; i<2; i++) {
UIButton * pickBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[pickBtn setFrame:CGRectMake(0, 30, 150, 150)];
pickBtn.tag = 666666+i;
if (i == 0) {
[pickBtn setCenterX:SCREEN_WIDTH/4];
[pickBtn setImage:[UIImage imageNamed:@"share微信"] forState:UIControlStateNormal];
[pickBtn setTitle:@"微信好友" forState:UIControlStateNormal];
[pickBtn addTarget:self action: @selector(FriendPick) forControlEvents:UIControlEventTouchUpInside];
}else{
[pickBtn setCenterX:SCREEN_WIDTH/4*3];
[pickBtn setImage:[UIImage imageNamed:@"share朋友圈"] forState:UIControlStateNormal];
[pickBtn setTitle:@"微信朋友圈" forState:UIControlStateNormal];
[pickBtn addTarget:self action: @selector(FriendQuanPick) forControlEvents:UIControlEventTouchUpInside];
}
pickBtn.titleLabel.font = [UIFont systemFontOfSize:12 weight:UIFontWeightRegular];
pickBtn.imageView.contentMode = UIViewContentModeScaleAspectFit;
[pickBtn setTitleColor:COLOR_WITH_HEX(0x222222) forState:UIControlStateNormal];
[CYtools adjustButtonImageViewUPTitleDownWithButton:pickBtn];
[BottomPickView addSubview:pickBtn];
}
}
-(void)FriendPick{
//判断是否安装了微信
if ([WXApi isWXAppInstalled]) {
[self ShareKindPick:@"friend"];
}else{
[self makeToast:@"请安装微信后再试"];
[self removeFromSuperview];
}
}
-(void)FriendQuanPick{
//判断是否安装了微信
if ([WXApi isWXAppInstalled]) {
[self ShareKindPick:@"Quan"];
}else{
[self makeToast:@"请安装微信后再试"];
if (self.failOpenWXBlock) {
self.failOpenWXBlock();
}
[self removeFromSuperview];
}
}
-(void)ShareKindPick:(NSString *)Type{
if (self.ShareImageNameStr.length>0) {
[self shareImageWithType:Type];
}else{
[self sharePathWith_SPath:self.sharePath andTitle:self.shareTitle andDescriptionStr:self.shareDescripTion andType:Type];
}
}
//分享一个链接
-(void)sharePathWith_SPath:(NSString *)Path andTitle:(NSString *)titleStr andDescriptionStr:(NSString *)descripStr andType:(NSString *)Type{
WXWebpageObject * pageObject = [WXWebpageObject object];
pageObject.webpageUrl = Path;
WXMediaMessage *message = [WXMediaMessage message];
message.title = titleStr;
message.description = descripStr;
[message setThumbImage:[UIImage imageNamed:@"sharePathHeader"]];
message.mediaObject = pageObject;

req.bText = NO;
req.message = message;
// req.text = Path;
if ([Type isEqualToString:@"friend"]) {
req.scene = WXSceneSession;
}else{
req.scene = WXSceneTimeline;
}
[WXApi sendReq:req completion:nil];
[self removeFromSuperview];
}
//我这里分享的是图片 如果你分享的是文字，网络连接等请看上面那个方法或者去开放平台官方查看参数设置
-(void)shareImageWithType:(NSString *)Type{
UIImage *image = [UIImage imageNamed:self.ShareImageNameStr];
NSData * imageData = UIImageJPEGRepresentation(image, 0.7);
WXImageObject *imageObject = [WXImageObject object];
imageObject.imageData = imageData;
WXMediaMessage *message = [WXMediaMessage message];
//这里是新添加的一个参数 作用官方文档里有写 并不会显示在分享内容中
NSString *filePath = [[NSBundle mainBundle] pathForResource:self.ShareImageNameStr
ofType:@"png"];
message.thumbData = [NSData dataWithContentsOfFile:filePath];
message.mediaObject = imageObject;
SendMessageToWXReq *req = [[SendMessageToWXReq alloc] init];
req.bText = NO;
req.message = message;
if ([Type isEqualToString:@"friend"]) {
req.scene = WXSceneSession;
}else{
req.scene = WXSceneTimeline;
}
[WXApi sendReq:req completion:nil];
[self removeFromSuperview];
}
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
[self removeFromSuperview];
