应用方法
支付宝外部应用跳转处理
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary )launchOptions {
/
如：跳转支付宝app支付时，app被kill，支付完成后，从支付宝app跳转回app（即重新启动），
return NO 不调用application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options，
直接返回首页
*/
if (launchOptions) {
NSString *appIDF = [launchOptions objectForKey:UIApplicationLaunchOptionsSourceApplicationKey];
if (appIDF && [appIDF isEqualToString:@"com.alipay.iphoneclient"]) {
return NO;
//return YES;//需要处理返回的URL返回YES
}
return YES;
}
当程序入口函数返回YES时调用下面方法：
-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options {
NSString *urlStr = [urlabsoluteString];
// 支付宝app进app
if(sourceApplication && [sourceApplication isEqualToString:@"com.alipay.iphoneclient"]){
[[AlipaySDK defaultService] processOrderWithPaymentResult:urlstandbyCallback:^(NSDictionary *resultDic) {
NSDictionary *dict = @{ALIPayDidCompleteURLKey:urlStr};
[[NSNotificationCenter defaultCenter] postNotificationName:ALIPayFromZFBDidCompleteNotification object:resultDic userInfo:dict];
}];
}
returnYES;
}
在支付类初始化方法中:
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(processAliPayResult:)
name:ALIPayFromZFBDidCompleteNotification object:nil];
