toViewController、toSharedViewController 和 toModalViewController 之间的区别
与 TTURLMap 一起使用时，toViewController、toSharedViewController 和 toModalViewController 之间有什么区别？
TTURLMap* map = navigator.URLMap;
[map from:@"*" toViewController:[TTWebController class]];
[map from:@"tt://tabBar" toSharedViewController:[TabBarController class]];
[map from:@"tt://order?waitress=(initWithWaitress:)"
toModalViewController:[ContentController class]];
What are the differences between toViewController, toSharedViewController and toModalViewController when used with TTURLMap?
TTURLMap* map = navigator.URLMap;
[map from:@"*" toViewController:[TTWebController class]];
[map from:@"tt://tabBar" toSharedViewController:[TabBarController class]];
[map from:@"tt://order?waitress=(initWithWaitress:)"
toModalViewController:[ContentController class]];

使用
(void)from:(NSString*)URL toViewController:(id)target将始终从头开始重新创建 UIViewController，并且不会尝试重用现有的视图控制器。例如，如果您调用
TTOpenURL(@"tt://details/view/1)两次，它将创建视图控制器两次。另一方面，如果您使用
( void)from:(NSString*)URL toSharedViewController:(id)target，TTNaviagtor将以共享模式创建控制器并重用它们，这对于选项卡栏视图中的菜单很有用。如果你打电话
TTOpenURL(@"tt://menu/1)对于使用 toSharedViewController 创建的 url 两次，它将重用现有的视图控制器（如果控制器位于 TTNavigator 堆栈中并且未发布）通过内存警告）最后一个选项
(void)from:(NSString*)URL toModalViewController:(id)target将通过推送视图控制器来显示视图控制器，而不使用现有的UINavigationBar。如果您需要呈现“发送电子邮件”视图或已有 UINavigationBar 的视图，这会很有帮助。Using
(void)from:(NSString*)URL toViewController:(id)targetwill always recreate the UIViewController from scratch and won't try to reuse an existing view controller.So for example, if you call
TTOpenURL(@"tt://details/view/1)twice, it will create the view controller twice.On the other hand, if you use
(void)from:(NSString*)URL toSharedViewController:(id)target, theTTNaviagtorwill create the controllers in shared mode and reuse them. It's good for menus in tab bar views.so if you call
TTOpenURL(@"tt://menu/1)twice for a url that was created with toSharedViewController, it will reuse an existing view controller (if the controller is in the TTNavigator stack and wasn't released by a memory warning)the last option,
(void)from:(NSString*)URL toModalViewController:(id)targetwill display the view controller by pushing it without using the existingUINavigationBar. It's helpful if you need to present a "send email" view, or something that already has a UINavigationBar.
