支付宝
- 导入SDK
cocoapods导入pod 'AliPay'， 或者手动拖都可以，不详细说。 - 设置相关配置

- 调用支付
在需要调用的界面包含头文件 #import <AlipaySDK/AlipaySDK.h>
[[AlipaySDK defaultService] payOrder:@"后台返回给你的值" fromScheme:@"开始设置的url schemes" callback:^(NSDictionary *resultDic) {
NSString *resultStatus = resultDic[@"resultStatus"];
if ([resultStatus integerValue] == 9000){
//网页支付成功
}else{
//网页支付失败
}
}];
- 客户端支付结果回调
AppDelegate.m中包含头文件 #import <AlipaySDK/AlipaySDK.h>
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
if ([url.host isEqualToString:@"safepay"]) {
//跳转支付宝钱包进行支付，处理支付结果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
if ([resultDic[@"resultStatus"] integerValue] == 9000){
//成功
}else {
//失败
}
}];
return YES;
}else{
//这里判断是否发起的请求为微信支付，如果是的话，用WXApi的方法调起微信客户端的支付页面（://pay 之前的那串字符串就是你的APPID，）
return [WXApi handleOpenURL:url delegate:self];
}
}
// NOTE: 9.0以后使用新API接口

Appdelegate.m 中先注册 包含头文件#import "WXApi.h"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.backgroundColor = [UIColor whiteColor];
//注册

return YES;
}
- 调用支付

//字典是是后台返回给你的数据 对应的键值对可能不一样，根据实际情况来写

// 这个是时间戳，也是在后台生成的，为了验证支付的

//发送请求到微信，等待微信返回onResp

- 微信支付结果回调
请参考开始支付宝结果回调，两个方法中有写到微信，接下来就只写微信支付结果的处理，也是在appdelegate中实现
#pragma mark - 微信支付
//9.0前的方法，为了适配低版本 保留
- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
return [WXApi handleOpenURL:url delegate:self];
}
//微信SDK自带的方法，处理从微信客户端完成操作后返回程序之后的回调方法,显示支付结果的
-(void) onResp:(BaseResp*)resp
{
//启动微信支付的response
NSString *payResoult = [NSString stringWithFormat:@"errcode:%d", resp.errCode];
if([resp isKindOfClass:[PayResp class]]){
//支付返回结果，实际支付结果需要去微信服务器端查询
switch (resp.errCode) {
case 0:
payResoult = @"支付结果：成功！";
break;
case -1:
payResoult = @"支付结果：失败！";
break;
case -2:
payResoult = @"用户已经退出支付！";
break;
default:
payResoult = [NSString stringWithFormat:@"支付结果：失败！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
break;
}
}
}
附
可以在获取支付结果成功或失败的时候发送通知，以便在支付的界面处理成功或失败的操作
//支付宝发送支付结果通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"AliPay" object:resultDic[@"resultStatus"]];
//在调用支付界面接受通知（viewDidLoad中实现）
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(alipay:) name:@"AliPay" object:nil];
//支付宝客户端支付成功通知
- (void)alipay:(NSNotification *)not{
if ([not.object isEqualToString:@"9000"]) {
//支付成功
}else if ([not.object isEqualToString:@"6001"]){
//用户取消支付
}else{
//支付失败
}
[[NSNotificationCenter defaultCenter] removeObserver:not];
}
//微信发送支付结果通知
[[NSNotificationCenter defaultCenter] postNotificationName:@"WechatPay" object:[NSString stringWithFormat:@"%d", resp.errCode]];
//在调用支付界面接受通知（viewDidLoad中实现）
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(wechatPayResult:) name:@"WechatPay" object:nil];
#pragma mark - 微信回调
- (void)wechatPayResult:(NSNotification *)not{
if ([not.object integerValue] == 0) {
//支付成功
}else if ([not.object integerValue] == -1){
//支付失败
}else if ([not.object integerValue] == -2){
//用户退出支付
}
[[NSNotificationCenter defaultCenter] removeObserver:not];
}
