iphone - Remove Unused ViewControllers -

When I sends click TTTabBar, tabs elected ViewController me right, then I will be a TTTabBar anywhere Click me to send each other ... etc, but how can I remove the last ViewController, so they just do not stacking on top of each other.

  - (minus) tabBar: (TTTabBar *) tabBar tabSelected: (NSInteger) SelectedIndex {if (SelectedIndex == 0) {UIViewController * ViewController = (UIViewController *) [[TTNavigator navigator] viewControllerForURL : @ "TT: // forum"]; [Self.view addSubview: viewController.view]; [Self.view addSubview: _tabBar]; } Else if (SelectedIndex == 1) {UIViewController * ViewController = (UIViewController *) [[TTNavigator sailor] viewControllerForURL: @ "TT: // profile"]; [Self.view addSubview: viewController.view]; [Self.view addSubview: _tabBar]; } Else if (SelectedIndex == 2) {UIViewController * ViewController = (UIViewController *) [[TTNavigator sailor] viewControllerForURL: @ "TT: // PMS"]; [Self.view addSubview: viewController.view]; [Self.view addSubview: _tabBar]; } Else if (SelectedIndex == 3) {UIViewController * ViewController = (UIViewController *) [[TTNavigator sailor] viewControllerForURL: @ "TT: // Friends"]; [Self.view addSubview: viewController.view]; [Self.view addSubview: _tabBar]; }}    I got this job  
  if ([ViewController isKindOfClass: [UIViewController class]]) {[viewController.view removeFromSuperview]; } {   Use  
  Use:  
  - (zero) removeFromSuperview    In your scenario you have to keep the context of the current scene or make a way to refer to it by using a tag.

visual studio 2010 - How to reinstall MVC 2 tools for VS2010? -



    I uninstalled ASP.Net MVC 2 device for Visual Studio 2010. How can I restore it? MVC2 downloads seem to include only the VS2008 device.   Whatever I said, says that MVC 2 has been included in VS2010, but the installation of an improvement did not fix it, and MVC 2 is not listed. Add VS2010 / Select a component in the Remove screen.      You will get your VS2010ToolsMVC2.msi VS2010 DVD under WCU \ ASPNETMVC - hopefully it will do!

Something like this will appear in the proxy code.    #! / Bin / bash if [[`git log_count`] ==" 0 "]]; Then there is no commodity for this repo. # What goods ... and echo are "one or more committed!" # What are the other things?    Any ideas?      you can    git rev-parse -verify HEAD    (after :)     This is a pipeline command, and its behavior vs. "  git diff " There is very little possibility to change   I find it more pronounced  rev-parse -verify  means "is this a valid object name?"    This is your  show-ref .  You ask "Is there anything in this safe / head in the safe?"  I ask, "what current  head  exists?"   In practice, both of these are fair tests, because once you have a branch, so to achieve the  HEAD , some mock values will indicate manually lack of editing It is very diffic...
