4.适配iOS9系统，请移步适配iOS9系统

---

5.开始进行微信支付

• 第一步
  在AppDelegate中导入头文件
  #import "DWWXPayH.h"

---

在AppDelegate.m中的 - (BOOL)application:(UIApplication ＊)application didFinishLaunchingWithOptions:(NSDictionary ＊)launchOptions {

//方法中添加以下代码

  [[DWWXPay dw_sharedManager] dw_RegisterApp:@"你的appid" withDescription:@"你的项目Bundle Identifier"];

  return Yes;
}

---

在AppDelegate.m中添加以下三个个方法

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {

return [WXApi handleOpenURL:url delegate:[DWWXPay dw_sharedManager]];
}

---

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {

return [WXApi handleOpenURL:url delegate:[DWWXPay dw_sharedManager]];
}

---

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options{

return [WXApi handleOpenURL:url delegate:[DWWXPay dw_sharedManager]];
}//此方法是由于系统版本更新而出现的方法

---

• 第二步
  在需要使用微信支付的地方导入头文件
  #include "DWWXPayH.h"
  @interface ViewController (){

       DWWXPay *pay;

  }

  - (void)viewDidLoad {

      [super viewDidLoad];
      pay = [DWWXPay dw_sharedManager];

   }

---

在开始支付时调用以下代码

 NSString *xmlString = [pay dw_payMoenySetAppid:@"appid" Mch_id:@"商户id" PartnerKey:@"密钥" Body:@"商品信息" Out_trade_no:@"订单号" total_fee:1 Notify_url:@"回调地址" Trade_type:@"类型"];

---

  [pay dw_post:@"https://api.mch.weixin.qq.com/pay/unifiedorder" xml:xmlString return_ErrorCode:^(NSString *return_msg, NSString *err_code, NSString *err_code_des) {

   NSLog(@"付款出现错误:%@--%@--%@",return_msg,err_code,err_code_des);

} backResp:^(BaseResp *backResp) {

// NSLog(@"微信返回内容");

} backCode:^(NSString *backCode) {

    NSLog(@"微信支付返回结果为:%@",backCode);

} BackTrade_stateMsg:^(NSString *backTrade_stateMsg, NSString *backTrade_state) {

 }];

在开始查询订单时调用以下代码

NSString *xmlString = [pay dw_queryOrderSetAppid:@"appid" Mch_id:@"商户id" PartnerKey:@"商户密钥" Out_trade_no:@"订单号"];

---

 [pay dw_post:@"https://api.mch.weixin.qq.com/pay/orderquery" xml:xmlString return_ErrorCode:^(NSString *return_msg, NSString *err_code, NSString *err_code_des) {

 } backResp:^(BaseResp *backResp) {

 } backCode:^(NSString *backCode) {

 }BackTrade_stateMsg:^(NSString *backTrade_stateMsg, NSString *backTrade_state) {

   NSLog(@"返回订单状态%@------返回订单状态码%@",backTrade_stateMsg,backTrade_state);

 }];
