感谢码友

我把Swift版本整理下 供码友参考

func hookOldOpenUrl(tragetCls:AnyClass){

let cls = UIApplication.self

let originalSelector = #selector(UIApplication.openURL(_:))       

let swizzledSelector = #selector(g_openURL)

        let originalMethod = class_getInstanceMethod(cls, originalSelector)

let swizzledMethod = class_getInstanceMethod(tragetCls, swizzledSelector)

let didAddMethod: Bool = class_addMethod(cls, originalSelector, method_getImplementation(swizzledMethod!), method_getTypeEncoding(swizzledMethod!))

if didAddMethod {

class_replaceMethod(cls, swizzledSelector, method_getImplementation(originalMethod!), method_getTypeEncoding(originalMethod!))

} else {

method_exchangeImplementations(originalMethod!, swizzledMethod!)

}

}

@objc func g_openURL(url:URL)->Bool{

UIApplication.shared.open(url)

return true

}

我也有同样的问题，Xcode 15.3 iOS 18，微信分享正常； Xcode升级到16 后， iOS 18微信分享无法调起；

微信SDK升级到2.0.4后，此问题已解决

微信SDK没适配，暂时可以这样解决

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    [AppDelegate hookOldOpenUrl:AppDelegate.class];

}

- (BOOL)g_openURL:(NSURL*)url

{

    [UIApplication.sharedApplication openURL:url options:nil completionHandler:nil];

    return YES;

}




+ (void)hookOldOpenUrl:(Class)targetCls

{

    Class cls = [UIApplication class];

    

    if (cls) {

        

        Method originalMethod =class_getInstanceMethod(cls, @selector(openURL:));

        Method swizzledMethod =class_getInstanceMethod(targetCls, @selector(g_openURL:));

        

        if (!originalMethod || !swizzledMethod) {

            return;

        }

        

        IMP originalIMP = method_getImplementation(originalMethod);

        IMP swizzledIMP = method_getImplementation(swizzledMethod);

        const char *originalType = method_getTypeEncoding(originalMethod);

        const char *swizzledType = method_getTypeEncoding(swizzledMethod);

        

        class_replaceMethod(cls,@selector(openURL:),swizzledIMP,swizzledType);

        class_replaceMethod(cls,@selector(g_openURL:),originalIMP,originalType);

    }}

蹲个官方回复。

上面方法会返回App 再去拉起 微信，这个有好的解决方案吗

我是在分享扩展调用 openURL: 必现， （用 xcode16 iOS 18）, Xcode 15 build 的包没有问题

老哥，怎么解决的，需要使用 swizzle 黑魔法？
