1. 支付寶SDK集成
實現(xiàn)思路:
1.下載支付寶SDK
2.集成SDK到項目中，參考官方集成文檔。
3.調(diào)起支付寶SDK
NSString *appScheme = @"smartarena";
// NOTE: 將簽名成功字符串格式化為訂單字符串,請嚴(yán)格按照該格式
NSString *sdkParam = dict[@"sdkParam"];
NSString *orderString = [NSString stringWithFormat:@"%@",sdkParam];
// NOTE: 調(diào)用支付結(jié)果開始支付
[[AlipaySDK defaultService] payOrder:orderString fromScheme:appScheme callback:^(NSDictionary *resultDic) {
NSLog(@"payOrder reslut = %@",resultDic);
[[NSNotificationCenter defaultCenter] postNotificationName:@"AliPayEnded" object:resultDic];
}];
4.支付寶回調(diào)自己的app
appDelegate中處理回調(diào)的url, 通過通知的方式通知訂單頁面做出跳轉(zhuǎn)響應(yīng)。
為了兼容iOS的不同版本，需要在不同的openURL代理中處理支付寶的回調(diào)代碼
// NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
if ([url.host isEqualToString:@"safepay"]) { //支付寶付款成功后的回調(diào)
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"AliPay result = %@",resultDic);
[[NSNotificationCenter defaultCenter] postNotificationName:@"AliPayEnded" object:resultDic];
}];
return YES;
}
//iOS9 之前使用的接口
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
if ([url.host isEqualToString:@"safepay"]) {
//跳轉(zhuǎn)支付寶錢包進(jìn)行支付，處理支付結(jié)果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:^(NSDictionary *resultDic) {
NSLog(@"AliPay result = %@",resultDic);
[[NSNotificationCenter defaultCenter] postNotificationName:@"AliPayEnded" object:resultDic];
}];
return YES;
}
5.訂單頁收到支付返回通知后的處理
- (void)aliPayEndedWithNotification:(NSNotification *)notification {
NSDictionary *resultDict = notification.object;
NSString *resultStatus = [NSString stringWithFormat:@"%@", [resultDict objectForKey:@"resultStatus"]];
NSString *resultMessage = resultDict[@"memo"];
NSInteger statusCode = [resultStatus integerValue];
switch (statusCode) {
case AliPayResultSucceed:
case AlipayResultInProgress:
case AlipayResultUnkown:
{
//跳轉(zhuǎn)邏輯
//[self pushToOrderInfoVC];
}
break;
case AliPayResultCancelledByUser:
case AliPayResultNetworkError:
default:
{
[self.view showInfo:resultMessage autoHidden:YES interval:2.0];
}
break;
}
}
注意事項：
- 調(diào)起支付寶SDK時傳入的orderPay字符串參數(shù)是按一定順序拼接起來的加過簽的參數(shù)串，通常由服務(wù)端拼接好傳給前端。
- 調(diào)起支付寶SDK時的fromScheme是支付寶回調(diào)app的重要依據(jù)，通常為app在info中配置的URL Scheme.

2. 微信支付SDK集成
1.下載并集成微信SDK，如果之前集成過友盟或微信分享，則無需再集成。
2.Project-Info中，添加微信的AppKey
微信AppKey.png
3.appDelegate.m中注冊微信的appkey
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//微信支付
[WXApi registerApp:SA_WX_APPKEY];
}
4.調(diào)起微信SDK
PayReq *request = [[PayReq alloc] init];
request.partnerId = reqParam[@"partnerid"];
request.prepayId= reqParam[@"prepayid"];
request.package = @"Sign=WXPay";
request.nonceStr= dict[@"nonceStr"];
request.timeStamp = [dict[@"timestampLong"] intValue];
request.sign = reqParam[@"sign"];
[WXApi sendReq:request];
5.微信支付結(jié)束后的回調(diào)
// NOTE: 9.0以后使用新API接口
- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options
{
if ([url.absoluteString hasPrefix:SA_WX_APPKEY]) {
return [WXApi handleOpenURL:url delegate:[WXApiManager sharedManager]];
}
}
//iOS9以前的版本
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation
{
if ([url.absoluteString hasPrefix:SA_WX_APPKEY]) {
return [WXApi handleOpenURL:url delegate:[WXApiManager sharedManager]];
}
微信的回調(diào)是通過onResp:代理處理的，故封裝了一個單例類WXApiManager來處理微信的回調(diào)。
WXApiManager.h
#import "WXApi.h"
@interface WXApiManager : NSObject <WXApiDelegate>
+ (instancetype)sharedManager;
@end
WXApiManager.m
@interface WXApiManager()
@end
@implementation WXApiManager
#pragma mark - LifeCycle
+ (instancetype)sharedManager {
static dispatch_once_t onceToken;
static WXApiManager *instance;
dispatch_once(&onceToken, ^{
instance = [[WXApiManager alloc] init];
});
return instance;
}
#pragma mark - WXApiDelegate
- (void)onResp:(BaseResp *)resp
{
if([resp isKindOfClass:[PayResp class]]){
[[NSNotificationCenter defaultCenter] postNotificationName:@"WXPayEnded" object:resp];
//支付返回結(jié)果，實際支付結(jié)果需要去微信服務(wù)器端查詢
NSString *strMsg;
switch (resp.errCode) {
case WXSuccess:
strMsg = @"支付結(jié)果：成功！";
NSLog(@"支付成功－PaySuccess，retcode = %d", resp.errCode);
break;
default:
strMsg = [NSString stringWithFormat:@"支付結(jié)果：失??！retcode = %d, retstr = %@", resp.errCode,resp.errStr];
NSLog(@"錯誤，retcode = %d, retstr = %@", resp.errCode,resp.errStr);
break;
}
}
}
@end
6.訂單頁收到支付返回通知后的處理
- (void)wxPayEndedWithNotification:(NSNotification *)notification {
id object = notification.object;
if ([object isKindOfClass:[BaseResp class]]) {
BaseResp *baseResp = (BaseResp *)object;
switch (baseResp.errCode) {
case WXSuccess:
{
//跳轉(zhuǎn)邏輯
//[self pushToOrderInfoVC];
}
break;
case WXErrCodeUserCancel:
break;
default:
{
[self.view showInfo:baseResp.errStr autoHidden:YES interval:2.0];
}
break;
}
}
}
注意事項
iOS9以后，微信／支付寶支付成功后點(diǎn)擊左上角的返回也能返回到app，但是會收不到微信／支付寶的回調(diào)信息。
解決方案:
在支付頁面監(jiān)聽UIApplicationDidBecomeActiveNotification,當(dāng)監(jiān)聽到返回app的事件后，主動請求服務(wù)端，如果發(fā)現(xiàn)order已經(jīng)支付，則主動跳轉(zhuǎn)。
