老项目在iOS13以上的手机上跑，支付成功后发现没有走回调（在iOS13以下的版本正常）。查资料发现是因为iOS13的这些支付回调都在SceneDelegate中。SceneDelegate是Xcode11创建项目后自动生成的，负责AppDelegate的某些功能、iPadOS的多窗口功能，这里不作详细介绍。
为了弄SceneDelegate中的支付回调，先做好准备工作：
1.项目的info.list里加上新的key value（也可以新建一个项目，把新项目里的直接复制过来），如图。

2.AppDelegate.m里的变化
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch
if (@available(iOS 13.0, *)){
NSLog(@"========iOS13========");
}else {
[self baseSetting]; //加载设置一些第三方库 支付宝、微信、定位等等
[self initBaseController]; //创建window、导航栏等
}
return YES;
}
#pragma mark - UISceneSession lifecycle
- (UISceneConfiguration *)application:(UIApplication *)application configurationForConnectingSceneSession:(UISceneSession *)connectingSceneSession options:(UISceneConnectionOptions *)options API_AVAILABLE(ios(13.0)){
// Called when a new scene session is being created.
// Use this method to select a configuration to create the new scene with.
if (@available(iOS 13.0, *)){
return [[UISceneConfiguration alloc] initWithName:@"Default Configuration" sessionRole:connectingSceneSession.role];
}else {
return nil;
}
}
- (void)application:(UIApplication *)application didDiscardSceneSessions:(NSSet<UISceneSession *> *)sceneSessions API_AVAILABLE(ios(13.0)){
// Called when the user discards a scene session.
// If any sessions were discarded while the application was not running, this will be called shortly after application:didFinishLaunchingWithOptions.
// Use this method to release any resources that were specific to the discarded scenes, as they will not return.
}
3.SceneDelegate.h
#import <UIKit/UIKit.h>
NS_ASSUME_NONNULL_BEGIN
@interface SceneDelegate : UIResponder <UIWindowSceneDelegate>
@property (strong, nonatomic) UIWindow * window;
@end
NS_ASSUME_NONNULL_END
4.SceneDelegate.m .m里创建window的方式发生了变化，这里要注意一下
- (void)scene:(UIScene *)scene willConnectToSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions API_AVAILABLE(ios(13.0)){
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
if (@available(iOS 13.0, *)){
[self baseSetting]; //加载设置一些第三方库 支付宝、微信、定位等等
[self initBaseControllerWithScene:(UIWindowScene *)scene andWithSession:session options:connectionOptions]; //创建window、导航栏等
}
}
-(void)initBaseControllerWithScene:(UIWindowScene *)scene andWithSession:(UISceneSession *)session options:(UISceneConnectionOptions *)connectionOptions
API_AVAILABLE(ios(13.0)){
self.window = [[UIWindow alloc] initWithWindowScene:scene];
self.window.frame = scene.coordinateSpace.bounds;
self.window.backgroundColor = WHITE_Color;
[self.window makeKeyAndVisible];
//创建导航栏什么的
//...... self.window.rootViewController = ;
}
- (void)scene:(UIScene *)scene openURLContexts:(NSSet<UIOpenURLContext *> *)URLContexts
API_AVAILABLE(ios(13.0))
{
NSEnumerator *enumerator = [URLContexts objectEnumerator];
UIOpenURLContext *context;
while (context = [enumerator nextObject]) {
NSURL *url = context.URL;
if([[NSString stringWithFormat:@"%@",url] rangeOfString:@"Wechat_Login"].location != NSNotFound)
{ //微信登录
//#define appDelegate ((AppDelegate *)[[UIApplication sharedApplication] delegate])
vc //login登录页面
[WXApi handleOpenURL:url delegate:vc];
}else if(([url.host isEqualToString:@"pay"] || [url.host isEqualToString:@"resendContextReqByScheme"] || [url.host isEqualToString:@"platformId=wechat"]) && [url.scheme isEqualToString:@"你的微信appid：wx************"]){
//"微信支付分授权和微信支付等回调====>我写在WXPayService.m的delegate方法中了，可以自己封装一下"
[WXApi handleOpenURL:url delegate:[WXPayService sharedInstance]];
}else if ([url.host isEqualToString:@"safepay"]) { //支付宝登录和支付
NSString *scope = [NSString getParamByName:@"scope" URLString:[NSString stringWithFormat:@"%@",url]];
if ([scope isEqualToString:@"kuaijie"]) { //支付宝快捷登录
[[AlipaySDK defaultService] processAuth_V2Result:url standbyCallback:nil];
}else {
//跳转支付宝钱包进行支付，处理支付结果
[[AlipaySDK defaultService] processOrderWithPaymentResult:url standbyCallback:nil];
}
}
}
}
NSString的Category
#pragma mark - ==========获取url中的参数==========
+ (NSString *)getParamByName:(NSString *)name URLString:(NSString *)url
{
NSError *error;
NSString *regTags=[[NSString alloc] initWithFormat:@"(^|&|\\?)+%@=+([^&]*)(&|$)", name];
NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:regTags
options:NSRegularExpressionCaseInsensitive
error:&error];
// 执行匹配的过程
NSArray *matches = [regex matchesInString:url
options:0
range:NSMakeRange(0, [url length])];
for (NSTextCheckingResult *match in matches) {
NSString *tagValue = [url substringWithRange:[match rangeAtIndex:2]]; // 分组2所对应的串
return tagValue;
}
return @"";
}
这下就能收到支付成功/失败的回调了，有问题或者我写的哪里有问题欢迎留言指正。
