iOS 26 系统兼容适配：UITabBar 液态玻璃效果与 WiFi SSID 获取

原因：AVAssetExportSession -11800 / -16979 转码失败，权限不足、文件不可读。创建一个由 URL 标识的代表任何资源的 asset 对象时，传入的 originFilePath 示例：file:///var/mobile/Media/DCIM/100APPLE/IMG_0426.MOV，没有读的权限，因为 iOS 26 对相册视频读取权限收紧。

代码示例：

// originFilePath 示例：file:///var/mobile/Media/DCIM/100APPLE/IMG_0426.MOV
AVURLAsset *asset = [AVURLAsset URLAssetWithURL:originFilePath options:nil]; 

兼容处理：先将相册的视频拷贝到 App 沙盒临时目录，然后再去创建资源对象 AVURLAsset。

[self copyVideoToSandbox:originFilePath completion:^(NSURL *localUrl) {
    AVURLAsset *asset = [AVURLAsset URLAssetWithURL:localUrl options:nil];
}];

- (void)copyVideoToSandbox:(NSURL *)originUrl completion:(void (^)(NSURL *localUrl))completion {
    NSString *temp = [NSTemporaryDirectory() stringByAppendingPathComponent:@"tempVideo.mov"];
    NSURL *localUrl = [NSURL fileURLWithPath:temp];
    NSFileManager *fm = [NSFileManager defaultManager];
    if ([fm fileExistsAtPath:temp]) {
        [fm removeItemAtPath:temp error:nil];
    }
    NSError *err = nil;
    BOOL ok = [fm copyItemAtURL:originUrl toURL:localUrl error:&err];
    if (!ok || err) {
        NSLog(@"拷贝失败：%@", err);
        completion(nil);
        return;
    }
    completion(localUrl);
}

5. 通过 CNCopySupportedInterfaces 获取 wifi ssid 的方式已失效

class func getWifiSSID() -> String? {
    var wifiName: String?
    let wifiInterfaces = CNCopySupportedInterfaces()
    if wifiInterfaces != nil {
        let interfaceArr = CFBridgingRetain(wifiInterfaces) as! [String]
        if interfaceArr.count > 0 {
            let interfaceName = interfaceArr[0] as CFString
            let ussafeInterfaceData = CNCopyCurrentNetworkInfo(interfaceName)
            if ussafeInterfaceData != nil {
                let interfaceData = ussafeInterfaceData as! [String: Any]
                wifiName = interfaceData["SSID"] as? String ?? ""
            } else {
                return nil
            }
        }
    }
    return wifiName
}

原因：iOS 26 不再推荐使用 CNCopySupportedInterfaces，在 iOS 26 将返回空值。

兼容处理：Capabilities 添加 Access WiFi Information 权限；通过 CLLocationManager 确保有定位权限，然后使用 NEHotspotNetwork 获取 wifi ssid：

NEHotspotNetwork.fetchCurrent { curNetwork in
    block(curNetwork?.ssid ?? "")
}
