SceneDelegate管理Window,导入SVProgre

崩溃报错为:找不到Appdelegate里的window

-[项目名.AppDelegate window]: unrecognized selector sent to instance

定位报错位置为:

dispatch_once(&once, ^{ sharedView = [[self alloc] initWithFrame:[[[UIApplication sharedApplication] delegate] window].bounds]; });

解决方法:

第一步:在AppDelegate中键加入window属性

class AppDelegate: UIResponder, UIApplicationDelegate {
    var window: UIWindow?
}

第二步:SVProgressHUD.m的638行改为

self.frame = [UIApplication sharedApplication].keyWindow.bounds;

至此问题解决
