微信支付 VS 支付宝支付
(1)没有安装微信app,是不能进行微信支付的
(2)没有安装支付宝app,也能支付,支付宝SDK提供了支付的H5页

一、项目配置:

二、 代码:

  1. Targets/Info/URL Types 中添加URL Schemes:

2.在需要的地方导入微信支付的SDK头文件:

#import <WXApi.h>
  1. AJGoodsCashierController.m 文件:
    (1)增加&移除 微信支付结果的观察者:
//添加“微信支付结果”通知的观察者
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getWeiXinpayOrderPayResult:) name:@"kWeiXinPayResultNotification" object:nil];

-(void)dealloc {
    //移除观察者
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

(2)微信支付相关:

#pragma mark - 微信支付相关
/**
 微信支付

 @param model 后台返回的微信支付需要的参数model
 */
- (void)weiXinPayWithModel:(AJWeiXinPayModel *)model {
    //注册
    if ([WXApi registerApp:model.appid withDescription:@"手报"]) {
        //调起支付
        PayReq *request = [[PayReq alloc] init];
        request.partnerId = model.partnerid;
        request.prepayId= model.prepayid;
        request.package = model.package;
        request.nonceStr= model.noncestr;
        request.timeStamp= model.timestamp;
        request.sign= model.sign;
        
        [WXApi sendReq:request];
    }
}
/**接收到通知的回调 - “微信支付结果”*/
-(void)getWeiXinpayOrderPayResult:(NSNotification *)notification {
    if (notification.userInfo != nil) {
        NSDictionary * resultDic = notification.userInfo;
        NSString * resultStatus = [resultDic valueForKey:@"isSuccess"];
        if ([resultStatus isEqualToString:@"1"]) {//支付成功
            [self setPayResultUIWithIsSuccess:true];
        } else {//支付失败
            [self setPayResultUIWithIsSuccess:false];
        }
    }
}
  1. AJWeiXinPayModel.h 文件:
@property (nonatomic ,copy)NSString * appid;//微信开放平台中注册的id
@property (nonatomic ,copy)NSString * noncestr;
@property (nonatomic ,copy)NSString * package;
@property (nonatomic ,copy)NSString * partnerid;
@property (nonatomic ,copy)NSString * prepayid;
@property (nonatomic ,copy)NSString * sign;
@property (nonatomic, assign)UInt32 timestamp;
  1. AppDelegate.m文件:
#pragma mark - 微信支付的接入
// NOTE: 9.0之前使用的API接口
- (BOOL)application:(UIApplication *)application
            openURL:(NSURL *)url
  sourceApplication:(NSString *)sourceApplication
         annotation:(id)annotation
{
    //微信支付
    if ([[url host] isEqualToString:@"pay"]) {
        [WXApi handleOpenURL:url delegate:self];
    }
    
    return YES;
}
// NOTE: 9.0及以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
    //微信支付
    if ([[url host] isEqualToString:@"pay"]) {
        [WXApi handleOpenURL:url delegate:self];
    }
    
    return YES;
}
/**微信支付结果回调*/
- (void)onResp:(BaseResp *)resp{
    if ([resp isKindOfClass:[PayResp class]]){
        PayResp * response = (PayResp *)resp;
        switch(response.errCode){
            case WXSuccess:
                //服务器端查询支付通知或查询API返回的结果再提示成功
                NSLog(@"支付成功");
                [self postWeiXinPayResultNotificationWithIsSuccess:true];
                break;
            default:
                NSLog(@"支付失败,retcode=%d",resp.errCode);
                [self postWeiXinPayResultNotificationWithIsSuccess:false];
                break;
        }
    }
}
/**发送微信支付结果的通知*/
-(void)postWeiXinPayResultNotificationWithIsSuccess:(BOOL)isSuccess {
    NSMutableDictionary * dict = [[NSMutableDictionary alloc] init];
    if (isSuccess) {
        [dict setValue:@"1" forKey:@"isSuccess"];//成功
    } else {
        [dict setValue:@"0" forKey:@"isSuccess"];//失败
    }
    [NSNotificationCenter.defaultCenter postNotificationName:@"kWeiXinPayResultNotification" object:nil userInfo:dict];
}
