1. 在AppDelegate.h中
(1) 导入微信类 #import @"WXApi.h".
(2) 遵守微信代理方法
2. 在APPDelegate.m中
(1) 注册微信
#pragma mark 注册微信
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//注册 微信
/**
参数1 : 微信Appid
参数2 : 对项目的描述信息(用项目名称)
*/
[WXApi registerApp:@"微信Appid" withDescription:@"云宴"];
return YES;
}
(2) 跳转方法,并设置代理
#pragma mark 跳转处理
//被废弃的方法. 但是在低版本中会用到.建议写上
-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation{
return [WXApi handleOpenURL:url delegate:self];
}
//被废弃的方法. 但是在低版本中会用到.建议写上
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
return [WXApi handleOpenURL:url delegate:self];
}
//新的方法
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary*)options
{
return [WXApi handleOpenURL:url delegate:self];
}
(3) 微信回调方法 (注意: 不要写成Req方法了)
#pragma mark 微信回调方法
- (void)onResp:(BaseResp *)resp
{
NSString * strMsg = [NSString stringWithFormat:@"errorCode: %d",resp.errCode];
NSLog(@"strMsg: %@",strMsg);
NSString * errStr = [NSString stringWithFormat:@"errStr: %@",resp.errStr];
NSLog(@"errStr: %@",errStr);
NSString * strTitle;
//判断是微信消息的回调 --> 是支付回调回来的还是消息回调回来的.
if ([resp isKindOfClass:[SendMessageToWXResp class]])
{
strTitle = [NSString stringWithFormat:@"发送媒体消息的结果"];
}
NSString * wxPayResult;
//判断是否是微信支付回调 (注意是PayResp 而不是PayReq)
if ([resp isKindOfClass:[PayResp class]])
{
//支付返回的结果, 实际支付结果需要去微信服务器端查询
strTitle = [NSString stringWithFormat:@"支付结果"];
switch (resp.errCode)
{
case WXSuccess:
{
strMsg = @"支付结果:";
NSLog(@"支付成功: %d",resp.errCode);
wxPayResult = @"success";
break;
}
case WXErrCodeUserCancel:
{
strMsg = @"用户取消了支付";
NSLog(@"用户取消支付: %d",resp.errCode);
wxPayResult = @"cancel";
break;
}
default:
{
strMsg = [NSString stringWithFormat:@"支付失败! code: %d errorStr: %@",resp.errCode,resp.errStr];
NSLog(@":支付失败: code: %d str: %@",resp.errCode,resp.errStr);
wxPayResult = @"faile";
break;
}
}
//发出通知 从微信回调回来之后,发一个通知,让请求支付的页面接收消息,并且展示出来,或者进行一些自定义的展示或者跳转
NSNotification * notification = [NSNotification notificationWithName:@"WXPay" object:wxPayResult];
[[NSNotificationCenter defaultCenter] postNotification:notification];
}
}
3. 在ViewController.h (进行支付请求的类)
暂时没有任何操作
4. 在ViewController.m中(进行支付的请求的类)
(1) 导入微信库 #import @"WXApi.h"
(2) 监听APPDelegate.m中发送的通知
#pragma mark 监听通知
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:YES];
//检测是否装了微信软件
if ([WXApi isWXAppInstalled])
{
//监听通知
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(getOrderPayResult:) name:@"WXPay" object:nil];
}
}
#pragma mark - 事件
- (void)getOrderPayResult:(NSNotification *)notification
{
NSLog(@"userInfo: %@",notification.userInfo);
if ([notification.object isEqualToString:@"success"])
{
UIAlertView * alertView = [[UIAlertView alloc] initWithTitle:@"提示信息" message:@"支付成功" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil, nil];
[alertView show];
}
else{
[self alert:@"提示" msg:@"支付失败"];
}
}
//客户端提示信息
- (void)alert:(NSString *)title msg:(NSString *)msg
{
UIAlertView *alter = [[UIAlertView alloc] initWithTitle:title message:msg delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alter show];
}
(3) 移除通知
#pragma mark 移除通知
- (void)dealloc
{
//移除通知
[[NSNotificationCenter defaultCenter] removeObserver:self];
}
