背景： 接觸到iOS 逆天的注入式框架 FLEX，有諸多功能，包括查看控件的坐標(biāo)和屬性，查看任何一個(gè)對(duì)象的屬性和成員變量，動(dòng)態(tài)修改屬性和成員變量，動(dòng)態(tài)的調(diào)用實(shí)例和類方法等等。為了方便隨時(shí)隨地的調(diào)用而不影響業(yè)務(wù)的邏輯功能，就打算將調(diào)用位置設(shè)在狀態(tài)欄。

注意：在iOS13之后，狀態(tài)欄的管理全都由 UIStatusBarManager 這個(gè)類管理。

代碼實(shí)現(xiàn)如下：

- (void)addStatusBarAction {
#if DEBUG
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_13_0
    if (@available(iOS 13.0, *)) {
        __weak __typeof(self) weakSelf = self;
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
            UIStatusBarManager *statusBarmanager = [UIApplication sharedApplication].keyWindow.windowScene.statusBarManager;
            SEL sel = NSSelectorFromString(@"handleTapAction:");
            [statusBarmanager aspect_hookSelector:sel withOptions:AspectPositionAfter usingBlock:^(id<AspectInfo> aspectInfo, id tapObj) {
                [weakSelf onClickStatusBar];
            } error:nil];
        });
    } else {
        __weak __typeof(self) weakSelf = self;
        Class statusBar = NSClassFromString(@"UIStatusBar");
        if (statusBar) {
            SEL sel = NSSelectorFromString(@"touchesEnded:withEvent:");
            [statusBar aspect_hookSelector:sel withOptions:AspectPositionAfter usingBlock:^(id<AspectInfo> aspectInfo, NSSet *touches, UIEvent *event) {
                [weakSelf onClickStatusBar];
            } error:nil];
        }
    }
#endif
#endif
}

- (void)onClickStatusBar {
    [[FLEXManager sharedManager] toggleExplorer];
}
