在需要調(diào)用的界面包含頭文件 #import <AlipaySDK/AlipaySDK.h>

- 微信支付結(jié)果回調(diào)
請(qǐng)參考開始支付寶結(jié)果回調(diào)渠啤，兩個(gè)方法中有寫到微信狐肢，接下來就只寫微信支付結(jié)果的處理，也是在appdelegate中實(shí)現(xiàn)
#pragma mark - 微信支付
//9.0前的方法沥曹，為了適配低版本 保留
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
return [WXApi handleOpenURL:url delegate:self];
}
//微信SDK自帶的方法份名，處理從微信客戶端完成操作后返回程序之后的回調(diào)方法,顯示支付結(jié)果的
-(void) onResp:(BaseResp*)resp
{
//啟動(dòng)微信支付的response
NSString *payResoult = [NSString stringWithFormat:@"errcode:%d", resp.errCode];
if([resp isKindOfClass:[PayResp class]]){
//支付返回結(jié)果，實(shí)際支付結(jié)果需要去微信服務(wù)器端查詢
switch (resp.errCode) {
case 0:
payResoult = @"支付結(jié)果：成功妓美！";
break;
case -1:
payResoult = @"支付結(jié)果：失斀┫佟！";
break;
case -2:
payResoult = @"用戶已經(jīng)退出支付壶栋！";
break;
default:
payResoult = [NSString stringWithFormat:@"支付結(jié)果：失敵饺纭！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
break;
}
}
}
附
可以在獲取支付結(jié)果成功或失敗的時(shí)候發(fā)送通知贵试，以便在支付的界面處理成功或失敗的操作
//支付寶發(fā)送支付結(jié)果通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"AliPay" object:resultDic[@"resultStatus"]];
//在調(diào)用支付界面接受通知（viewDidLoad中實(shí)現(xiàn)）
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(alipay:) name:@"AliPay" object:nil];
//支付寶客戶端支付成功通知
- (void)alipay:(NSNotification *)not{
if ([not.object isEqualToString:@"9000"]) {
//支付成功
}else if ([not.object isEqualToString:@"6001"]){
//用戶取消支付
}else{
//支付失敗
}
[[NSNotificationCenter defaultCenter] removeObserver:not];
}
//微信發(fā)送支付結(jié)果通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"WechatPay" object:[NSString stringWithFormat:@"%d", resp.errCode]];
//在調(diào)用支付界面接受通知（viewDidLoad中實(shí)現(xiàn)）
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(wechatPayResult:) name:@"WechatPay" object:nil];
#pragma mark - 微信回調(diào)
- (void)wechatPayResult:(NSNotification *)not{
if ([not.object integerValue] == 0) {
//支付成功
}else if ([not.object integerValue] == -1){
//支付失敗
}else if ([not.object integerValue] == -2){
//用戶退出支付
}
[[NSNotificationCenter defaultCenter] removeObserver:not];
}
