pushviewcontroller

问题 I have a tabBar application. One of the tabs has a rootviewcontroller that creates a UITableView and adds it to the subview. When a user clicks a cell in the UITableView I want to push a new rootviewcontroller but I cant get it to work. In my appDelegate: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //Create the window self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease]; //Create the

问题 Okay, here is my issue: My app has a display of categories in the tab bar at the bottom of the iPhoneOS screen. This only allows 5 categories before it presents the MORE button. I have over 25 (please do not answer this by saying: "Rethink your application...etc" -- that was rudely said before. They are food, drink, etc categories and cannot be changed). I want to allow the user to put their favorites on the home page. The Apple moreNavigationController editing system only allows 20 tab bar

问题 It looks like I found a bug in the navigationController pushViewController method. To recreate it I took the sample master detail project and made some changes to the -didSelectRow: method: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { DetailViewController* view = [self.storyboard instantiateViewControllerWithIdentifier: @"view"]; NSDate *object = _objects[indexPath.row]; [view setDetailItem:object]; [self.detailViewController

问题 I have a question about iOS push navigation controllers. I want to push view controller on slide gesture. Just like as in Snapchat application: main view captures images. If you slide from left to right, snapchat messages view smoothly slides (pushes) to main window. If you slide from right to left > contacts view. How to create this kind of navigation? Thanks a lot! 回答1: I believe the way that Snapchat does it is through UIViewController containment. Essentially, the main view controller

问题 I'm getting the following runtime error and I cannot determine for the life of me WHYYYY. The error is Thread 1: EXC_BREAKPOINT (code=EXC_1386_BPT, subcode=0x0) which seems to happen whenever I execute the dismissModalViewController:animated or the pushViewController:animated method from any of my VC's. I have enabled zombie objects and that shows me the following message in the debugger, 2012-06-14 16:34:58.769 MyApp[5952:17903] *** -[MyDetailsVC respondsToSelector:]: message sent to

问题 I am using a sample ViewController that is displayed in the sample program as a presentModalViewController. However, I want to use pushViewController on the UIViewController instead. The problem is that when I switch to pushViewController, the ViewController no displays properly. Functions in the ViewController are called, but I don't see anything.

问题 I'm trying to use the following code to display a tabbarcontroller UITabBarController *tc = [[self storyboard] instantiateViewControllerWithIdentifier:@"tabbarcontroller"]; [self.navigationController pushViewController:tc animated:YES]; It does load the view, and I can tell it which of the tabs I want it to default to.

问题 I'm doing a navigation based application. Let me explain a little bit about the application. At the program load table view will show 3 options like: Hotel Restaurants Cafe If a user selects any of the above options, it will navigate to another table view and show sub options.
