?嘗試解決方案一：

// ?*************代碼做調(diào)整，加入到下一個(gè)loop周期中，再次運(yùn)行代碼，程序正常。******// - (void)applicationDidBecomeActive:(UIApplication *)application {// Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.//crash in ios9_testWindow = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];_testWindow.hidden = NO;//ok// dispatch_async(dispatch_get_main_queue(), ^{// _testWindow = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];// _testWindow.hidden = NO;// }); } Or ?嘗試解決方案二： Xcode7 需要所有的窗口都必須有根控制器 XCODE 7 requires that all the Windows must have a rootViewController You can use easy: UIViewController* vc = [[UIViewController alloc]initWithNibName:nil bundle:nil];self.window.rootViewController = vc; It's working good if you need to use only UIWindow (for easy examples from any Tutorials - before Xcode 7)!
