I am using this Cocoa Control Side Menu link.
In this Menu, when you start the app you have a Navigation Bar for the first screen, but when you open the menu and press any element of TableView, the ViewController change without Navigation Bar. I want to have a Navigation Bar for each of the elements of the TableView Menu and a left button on the Navigation bar that could open and close the Menu.
I start the application with this code:
// appDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
YPMenuViewController *menuVC = [[YPMenuViewController alloc] init];
YPProfileViewController *contentVC = [[YPProfileViewController alloc] init];
UINavigationController *contentNavigationController = [[UINavigationController alloc] initWithRootViewController:contentVC];
YPSideMenuOptions *options = [[YPSideMenuOptions alloc] init];
YPSideMenuController *sideMenuController = [[YPSideMenuController alloc] initWithMenuViewController:menuVC
contentViewController:contentNavigationController
options:options];
self.window.rootViewController = sideMenuController;
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
After this, the app starts with Navigation bar.
But then, in the TableView If Select the view controllers like this, I have the Navigation Bar but without button to open an close
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
switch (indexPath.row) {
case 0:
{
YPProfileViewController *contentVC = [[YPProfileViewController alloc] init];
UINavigationController *contentNavigationController = [[UINavigationController alloc] initWithRootViewController:contentVC];
UIButton *iwantView = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 30, 30)];
[iwantView setBackgroundColor:[UIColor blackColor]];
[iwantView addTarget:self action:#selector(openMenu) forControlEvents:UIControlEventTouchUpInside];
contentNavigationController.navigationItem.leftBarButtonItem =[[UIBarButtonItem alloc] initWithCustomView:iwantView];
[[self sideMenuController] changeContentViewController:contentNavigationController closeMenu:YES];
break;
}
case 1:
{
YPProjectListViewController *contentVC = [[YPProjectListViewController alloc] init];
UINavigationController *contentNavigationController = [[UINavigationController alloc] initWithRootViewController:contentVC];
[[self sideMenuController] changeContentViewController:contentNavigationController closeMenu:YES];
break;
}
default:{
YPProfileViewController *contentVC = [[YPProfileViewController alloc] init];
[[self sideMenuController] changeContentViewController:contentVC closeMenu:YES];
break;
}
}
}
You are adding the button before the view controller is loaded, you should add it after loading the view in your content view controller.
#implementation YPProfileViewController
---------------
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
UIButton *iwantView = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 30, 30)];
[iwantView setBackgroundColor:[UIColor blackColor]];
[iwantView addTarget:self action:#selector(openMenu) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem =[[UIBarButtonItem alloc] initWithCustomView:iwantView];
}
Anyway I just added a method to add a menu button on the navigation bar more easily.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
[self addLeftMenuButtonWithImage:[UIImage imageNamed:#"menu_icon"]];
}

I have a problem about UIBarButtonItem on NavigationBar.
Transit from FirstViewController to SeconderViewController by pusuViewController.
Return to FirstViewController with return button on left side of NavigationBar.
[Problem happen] The Color of [next] button on right side of NavigationBar is transparent.
(You can tap [next] button althought the color is transparent )
This problem happen on iPhone8(iOS11.2.1(15C153), not heppen on iPhone6(iOS10.3.3(14G60)).
My code is below,
AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];
self.window.backgroundColor = UIColor.blackColor;
UIViewController *vc = [[FirstViewController alloc] init];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:vc];
self.window.rootViewController = nc;
[self.window makeKeyAndVisible];
return YES;
}
FirstViewContrtoller.m
- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.title = #"First View";
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(#"next", nil)
style:UIBarButtonItemStylePlain
target:self
action:#selector(touchUpNextButton:)];
self.navigationItem.rightBarButtonItem = nextButton;
}
- (void)touchUpNextButton:(id)sender
{
UIViewController *vc = [[SecondViewController alloc] init];
[self.navigationController pushViewController:vc animated:YES];
}
SecondViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.navigationItem.title = #"Second View";
}
I'd appreciate if you would provide me a good solution.
Thank you.
I think it is the bugs of iOS 11.2.1
You can temporary fix by following solution:
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc] initWithTitle:NSLocalizedString(#"next", nil)
style:UIBarButtonItemStylePlain
target:self
action:#selector(touchUpNextButton:)];
[nextButton setTitleTextAttributes:#{NSForegroundColorAttributeName : [self.view tintColor], NSFontAttributeName:[UIFont systemFontOfSize:16.9f]} forState:UIControlStateNormal];
Hope that can help you.
I have read many other threads on this and the Apple docs, but haven't found a solution yet for my particular problem.
My app uses a UITabBarController as the rootViewController, and in one of the tabs I have a UISegmentedControl in the navigationBar to switch between three child UITableViewControllers.
(In the real app two of the childVCs are a custom UIViewController, I'm just using three UITableViewControllers for the sample app).
The segmentedControl setup and the switching all works fine. The thing that goes wrong is that only the first UITableViewController is shown correctly. For the second and third one, part of the first cell is hidden under the navigationBar. When I click through all three, the first one is still ok.
I have made a little sample app to show what's going on, using very bright colors for demonstration purposes: https://www.dropbox.com/s/7pfutvn5jba6rva/SegmentedControlVC.zip?dl=0
Here is also some code (I'm not using storyboards):
// AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
FirstViewController *fvc = [[FirstViewController alloc] init];
UINavigationController *firstNavigationController = [[UINavigationController alloc] initWithRootViewController: fvc];
SecondViewController *svc = [[SecondViewController alloc] init];
UINavigationController *secondNavigationController = [[UINavigationController alloc] initWithRootViewController: svc];
// Initialize tab bar controller, add tabs controllers
UITabBarController *tabBarController = [[UITabBarController alloc] init];
tabBarController.viewControllers = #[firstNavigationController, secondNavigationController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.rootViewController = tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
// FirstViewController.m
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.title = #"One";
self.view.backgroundColor = [UIColor orangeColor];
UITableViewController *vc1 = [[UITableViewController alloc] init];
UITableViewController *vc2 = [[UITableViewController alloc] init];
UITableViewController *vc3 = [[UITableViewController alloc] init];
vc1.view.backgroundColor = [UIColor redColor];
vc2.view.backgroundColor = [UIColor blueColor];
vc3.view.backgroundColor = [UIColor greenColor];
self.viewControllers = #[vc1, vc2, vc3];
self.segmentTitles = #[#"Red", #"Blue", #"Green"];
self.segmentedControl = [[UISegmentedControl alloc] initWithItems: self.segmentTitles];
[self.segmentedControl addTarget: self
action: #selector(segmentClicked:)
forControlEvents: UIControlEventValueChanged];
self.navigationItem.titleView = self.segmentedControl;
self.segmentedControl.selectedSegmentIndex = 0;
// set the first child vc:
UIViewController *vc = self.viewControllers[0];
[self addChildViewController: vc];
vc.view.frame = self.view.bounds;
[self.view addSubview: vc.view];
self.currentVC = vc;
}
- (void)segmentClicked:(id)sender
{
if (sender == self.segmentedControl)
{
NSUInteger index = self.segmentedControl.selectedSegmentIndex;
[self loadViewController: self.viewControllers[index]];
}
}
- (void)loadViewController:(UIViewController *)vc
{
[self addChildViewController: vc];
[self transitionFromViewController: self.currentVC
toViewController: vc
duration: 1.0
options: UIViewAnimationOptionTransitionFlipFromBottom
animations: ^{
[self.currentVC.view removeFromSuperview];
vc.view.frame = self.view.bounds;
[self.view addSubview: vc.view];
} completion: ^(BOOL finished) {
[vc didMoveToParentViewController: self];
[self.currentVC removeFromParentViewController];
self.currentVC = vc;
}
];
}
So obviously my question is, why does this happen, and what can I do to fix it?
Edit: adding screenshots.
EDIT: Based on the answer below I changed the code in the animation block to:
[self.currentVC.view removeFromSuperview];
if ([vc.view isKindOfClass: [UIScrollView class]])
{
UIEdgeInsets edgeInsets = UIEdgeInsetsMake(self.topLayoutGuide.length, 0, self.bottomLayoutGuide.length, 0);
[UIView performWithoutAnimation: ^{
vc.view.frame = self.view.bounds;
((UIScrollView *)vc.view).contentInset = edgeInsets;
((UIScrollView *)vc.view).scrollIndicatorInsets = edgeInsets;
}];
}
else
{
vc.view.frame = self.view.bounds;
}
[self.view addSubview: vc.view];
Now it works. I'm going to try this with a custom UIViewController as well.
The issue is that you do not set the correct content inset to each table view. The system attempts to do it for you, but I guess your setup is too complex for it, and it only does it for the first tableview that is loaded in viewDidLoad. In your loadViewController: method, when replacing the currently displayed view, make sure to set both the contentInset and scrollIndicatorInsets to the values of the previous view. I think the system will manage to set the correct insets later, in case you rotate to landscape. Try it. If it doesn't, you will need to do it on your own in viewDidLayoutSubviews.
I'm having trouble trying to pop a view
App Delegate
#implementation MAAppDelegate
#synthesize navController;
#synthesize detailViewController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Init the navController for the Master Detail View of the grade cells
UINavigationController *navController = [[UINavigationController alloc] init];
detailViewController = [[UIViewController alloc] init]; //step6
navController = [[UINavigationController alloc] initWithRootViewController:[[MAController alloc] init]]; //step7
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window.backgroundColor = [UIColor whiteColor];
self.window.rootViewController = navController; //step8
[self.window makeKeyAndVisible];
// Set MAController as rootViewController
//self.window.rootViewController = [[MAController alloc] init];
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
// Use the insanely cool TSMessages to show network alerts
[TSMessage setDefaultViewController: self.window.rootViewController];
return YES;
}
First part of viewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
[self.navigationController setNavigationBarHidden:YES];
UIBarButtonItem *newBackButton = [[UIBarButtonItem alloc] initWithTitle:#"Home" style:UIBarButtonItemStyleBordered target:self action:#selector(home:)];
self.navigationItem.leftBarButtonItem=newBackButton;
Later, when I change the viewController
NSLog(#"Opened progress report");
UIViewController *detailViewControl = [[UIViewController alloc] init];
// Set progress report as the view controller
[self.navigationController pushViewController:detailViewControl animated:YES];
UIImage *background = [UIImage imageNamed:#"bg"];
// Add static image bg
self.backgroundImageView = [[UIImageView alloc] initWithImage:background];
self.backgroundImageView.contentMode = UIViewContentModeScaleAspectFill;
[self.view addSubview:self.backgroundImageView];
// Add blurred layer to image when tableView goes in front of it
self.blurredImageView = [[UIImageView alloc] init];
self.blurredImageView.contentMode = UIViewContentModeScaleAspectFill;
self.blurredImageView.alpha = 0;
[self.blurredImageView setImageToBlur:background blurRadius:10 completionBlock:nil];
[self.view addSubview:self.blurredImageView];
[self.navigationController setNavigationBarHidden:NO];
So I don't understand why that when I do this, a selector from the button (that I know fires, because I get Righthtere in my log):
-(void)home:(UIBarButtonItem *)sender {
NSLog(#"Righthtere");
// Set progress report as the view controller
[self.navigationController popToViewController:self animated:YES];
}
It doesn't go back to the initial view controller.
You seem to be confusing popToViewController and popViewControllerAnimated. popViewControllerAnimated removes the current view from the stack and brings the new stack top the active view controller. popToViewController pops the stack until the listed view controller is on top of the stack.
Since you are calling popToViewController with self, it will look and see that the requested view controller is already on top of the stack and do nothing. If you wish to go back one view controller then your call should be.
[self.navigationController popViewControllerAnimated:YES];
I use the below code to pop the previous viewcontroller in iOS 8.
[self presentModalViewController:viewcontroller animated:YES];
I'm developing an app for ios with a Tab Bar. I have more than 5 buttons on the bar, so on the iphone i have the button more.
Now, suppose i have this buttons: Button1 Button2 Button3 Button4 More (and inside More) Button5 Button6.
If i click More and then Button5 i go in the view relative to Button5. Then i click Button2 (that is not in the More) and i go in the view relative to Button2.
So far so good.
Now if i click More i go not to More Tab but back to the view relative to Button5.
How do i make the more button go always to the more view?
You don't need to add more button. Just set the view controllers to the UITabBarController
- (void)setViewControllers:(NSArray *)viewControllers animated:(BOOL)animated
and it will automatically create a more button if you have more than 5 view controllers! i.e. the count of NSArray is greater than 5.
Another way you could do is, whenever the user presses more, the first button gets removed and other buttons gets added.
Basically you can create an array and keep all the buttons inside it. And then based on the button pressed you can navigate to that particular view.
For Ex:
Initially you have: Button1 Button2 Button3 Button4 Next
After Clicking Next: Prev Button3 Button4 Button5 Button6
I used this code in my app delegate.m to solve the problem
- (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController {
UITabBarController* tabBarController2 = (UITabBarController*)self.window.rootViewController;
if (tabBarController2.selectedIndex < 4) {
[tabBarController2.moreNavigationController popViewControllerAnimated:NO];
}
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
UIViewController *viewController1 = [[UIViewController alloc] init];
UIViewController *viewController2 = [[UIViewController alloc] init];
UIViewController *viewController3 = [[UIViewController alloc] init];
UIViewController *viewController4 = [[UIViewController alloc] init];
UIViewController *viewController5 = [[UIViewController alloc] init];
UIViewController *viewController6 = [[UIViewController alloc] init];
UIViewController *viewController7 = [[UIViewController alloc] init];
UIViewController *viewController8 = [[UIViewController alloc] init];
UIViewController *viewController9 = [[UIViewController alloc] init];
[viewController1.view setBackgroundColor:[UIColor whiteColor]];
[viewController2.view setBackgroundColor:[UIColor redColor]];
[viewController3.view setBackgroundColor:[UIColor greenColor]];
[viewController4.view setBackgroundColor:[UIColor grayColor]];
[viewController5.view setBackgroundColor:[UIColor blueColor]];
[viewController6.view setBackgroundColor:[UIColor yellowColor]];
[viewController7.view setBackgroundColor:[UIColor brownColor]];
[viewController8.view setBackgroundColor:[UIColor magentaColor]];
[viewController9.view setBackgroundColor:[UIColor purpleColor]];
[viewController1 setTitle:#"one"];
[viewController2 setTitle:#"two"];
[viewController3 setTitle:#"three"];
[viewController4 setTitle:#"four"];
[viewController5 setTitle:#"five"];
[viewController6 setTitle:#"six"];
[viewController7 setTitle:#"seven"];
[viewController8 setTitle:#"eight"];
[viewController9 setTitle:#"nine"];
self.tabBarController = [[UITabBarController alloc] init];
self.tabBarController.viewControllers = #[viewController1, viewController2, viewController3, viewController4, viewController5, viewController6, viewController7, viewController8, viewController9];
self.window.rootViewController = self.tabBarController;
[self.window makeKeyAndVisible];
return YES;
}
I have added a sample AppDelegate code which I tried and its working absolutely fine for me. Let me know what problem your having in this.
Good evening,
I currently have two UIViewControllers. My appDelegate looks like this
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
struct CGRect rect = [[UIScreen mainScreen] bounds];
rect.origin.x = rect.origin.y = 0.0f;
_viewController = [[sandboxViewController alloc] init];
UINavigationController *nc = [[UINavigationController alloc] initWithRootViewController:_viewController];
_window = [[UIWindow alloc] initWithFrame:rect];
[_window makeKeyAndVisible];
[_window addSubview:nc.view];
return YES;
}
The viewController looks like this:
- (void)loadView {
self.view = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 480.0f)];
self.view.backgroundColor = [UIColor whiteColor];
self.navigationItem.title = #"Master View";
}
- (void)viewDidLoad
{
[super viewDidLoad];
UIButton *infoButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
[infoButton addTarget:self action:#selector(switchView:) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:infoButton];
}
- (void)switchView:(id)obj {
if(![self navigationController])
NSLog(#"navigationController IS NIL!!!");
if(!_secondView)
_secondView = [[secondViewController alloc] init];
[self.navigationController pushViewController:_secondView animated:YES];
}
By clicking on the info button, that was added to the right side on the navigation bar, I want to switch to the secondView. This, however, is not happening because navigationController logs as nil ! What am I missing here?
Any help is truly appreciated!
You don't have to create the window, it should already exist.
//_window = [[UIWindow alloc] initWithFrame:rect]; //remove this line
[self.window makeKeyAndVisible]; //use the ivar
[self.window addSubview:nc.view];
