I want to create sidebar menu with indicate UINavigationBar like below mention image.
By using ECSlidingviewController library i have done side menu. But thing is i need to display Navigation Indicator when user slide on menu.
How can i create? Any one having idea?
There is nothing special to do here.
Simply create your view and add it as a subview of the navigationBar in your controller (not the menu controller).
Here is a simple demonstration:
CGFloat desiredWidth = x;<----replace x.
UIView *testView = [[UIView alloc]initWithFrame:CGRectMake(-desiredWidth,0,desiredWidth,44)];
[testView setBackgroundColor:[UIColor blackColor]];
[self.navigationController.navigationBar addSubview:testView];

I am new to developing for iOS, but I am completely stumped with this.
Steps:
In Xcode, create a new tabbed application for iPhone.
Go into first subview and drag a Navigation Bar to the view.
Go into viewDidLoad and add this (assuming you have dropped logo.png into the project structure):
self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"logo.png"]];
Render the view - it does not work. No custom image replaces the default "Title" text.
I don't understand. Why does this not work? What do I have to do to make it work? Is there something fundamentally different I need to be doing or a concept I am not grasping fully here?
UPDATE
I have figured out that the code above works. You just need to embed your view inside a navigation controller. Click on the first tabbed view, then do Editor > Embed In > Navigation Controller. The code will then work, and you can continue moving forward. Just embed each tab in a navigation controller using the method above and you should be good to go!
The code you have will work if your controller is embedded in a navigation controller, but if you add a navigation bar manually, you need to make an IBOutlet to it (bar in my example), and get its navigation item,
- (void)viewDidLoad {
[super viewDidLoad];
UINavigationItem *item = self.bar.items[0];
item.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"logo.png"]];
}
May be the problem you are facing is because of not setting the frame. I face similar problem sometimes. Try this:
UIImageView *customTitleView = [[UIImageView alloc]initWithFrame:CGRectMake((320-210)/2, 0, 210, 50)];
customTitleView.backgroundColor = [UIColor redColor];
self.navigationItem.titleView = customTitleView;
Hope this helps. :)
I want to developer app with a custom navigation bar like in the following images:
I think that i need to subclass UINavigationBar and add button to centre of nav bar, but i don't really know how to make navigation bar look like on image. Can you please give me advice what should i do, links to any kind of documentation would be awesome!

EDIT:
My idea is next: make custom navigation bar height little bigger than default size, and add background image with arrow in it and with some transparency on the edges.
If you want a button (you probably do want) you can achieve it completely by subclassing UINavigationBar. You should remember that height of UINavigationBar is read-only property.
Style but not tappable:
So let's assume we subclass the navigation bar and add button there. You could do this and it will be going look great. For example:
- (void)drawRect:(CGRect)rect
{
self.backgroundColor = [UIColor lightGrayColor];
UIButton *myButton = [[UIButton alloc] initWithFrame:CGRectMake(self.frame.size.width/2-50, 0 , 100, 100)];
[myButton setBackgroundColor:[UIColor lightGrayColor]];
[myButton setTitle:#"Normal" forState:UIControlStateNormal];
[myButton setTitle:#"Highlighted" forState:UIControlStateHighlighted];
[self addSubview:myButton];
[self sendSubviewToBack:myButton];
}
But you will facing a problem that your button is non tapeable below UINvaigationBar. (I post an image on the bottom of the answer)
So there is clearly not a path you want to follow. Don't even try that.
Style but not tappable 2:
You may override this method in your navigation bar subclass
- (CGSize) sizeThatFits:(CGSize)size {
return CGSizeMake(custom_width, custom_height);
}
And then mask it using UIBezierPath for example
The right (tappable) way:
You have to create a view stick to your UINavigationBar. What i will do here (if you want it to every screen) is:
Make a Category of UIViewController which can draw (for example - this is easiest way) UIButton.
Style this 'UIButton' whatever you want (if you want
Pin action to 'UIButton': [btn addTarget:self action:#selector(menuShow:) forControlEvents:UIControlEventTouchUpInside];
menuShow: method should be declare in your category
You can call drawing button every time you want to redraw view controller.
As you can see there there will be two separates View: UINavigationBar and UIButton. This is allow you to set content under this little button and make it tapable.
So why just don't hide navigation bar, and use different view? Because iOS7 ;) When Apple change it in iOS7 for example then you have to rebuild your pseudo NavigationBar, with only additional view, you don't need to do anything.
You do not need to subclass UINavigationBar. Create UIView add to it UIImageView as background with image in the shape you need, add button.
Subclass UINavigationController hide UINavigationBar, add custom navigation bar.
First Hide navigation bar using -
self.navigationController.navigationBarHidden = YES;
Then create UIView with required height,height of navigationBar is 44px.Then create background image view, object of required UIButton and add all objects on created UIView as a subview.It will look like navigationBar.Thank you.
You can add your custom shaped view as titleView on the navigation bar.
Just make sure that clipsToBounds is set to NO, so it doesn't get clipped.
The iOS7 Facebook App has a right side menu that can be shown by swiping right to left or clicking on the upper right button. When this menu is opened the there is a color transition in the entire status bar from blue to black and vice-versa when closed.
This image shows both status bar side-to-side
This looks like a very good solution for iOS Apps with side menus.
Any ideas or ways about how to accomplish this?
I am currently using JASidePanels.
Thanks!
I managed to find a very simple, elegant way to do this, that mimics the Facebook app functionality perfectly.
Here's my approach:
Create view with status bar frame
Set view background color to black, opacity to 0
Add view as subview to any root view (you need a view that will cover both the center view and the menus, so that it won't be confined to any single view - a good option for this is the container view controller used by your menu controller implementation)
Set view's opacity in your menu controller implementation's menu animation method
Here's my specific implementation, using MMDrawerController:
I subclassed MMDrawerController (I actually already had a subclass for using MMDrawerController with storyboards), and added this code to the class's init method:
// Setup view behind status bar for fading during menu drawer animations
if (OSVersionIsAtLeastiOS7()) {
self.statusBarView = [[UIView alloc] initWithFrame:[[UIApplication sharedApplication] statusBarFrame]];
[self.statusBarView setBackgroundColor:[UIColor blackColor]];
[self.statusBarView setAlpha:0.0];
[self.view addSubview:self.statusBarView];
}
// Setup drawer animations
__weak __typeof(&*self) weakSelf = self; // Capture self weakly
[self setDrawerVisualStateBlock:^(MMDrawerController *drawerController, MMDrawerSide drawerSide, CGFloat percentVisible) {
MMDrawerControllerDrawerVisualStateBlock block;
block = (drawerSide == MMDrawerSideLeft) ? [MMDrawerVisualState parallaxVisualStateBlockWithParallaxFactor:15.0] : nil; // Right side animation : Left side animation
if(block){
block(drawerController, drawerSide, percentVisible);
}
[weakSelf.statusBarView setAlpha:percentVisible]; // THIS IS THE RELEVANT CODE
}];
I also added self.statusBarView as a private property.
The first section of code creates a view, configures it, and adds it as a subview of the MMDrawerController subclass's view. The OSVersionIsAtLeastiOS7() method is a custom method that simplifies the check to see if the device is running iOS 7 (if it isn't, your custom view will show up below the status bar, which you don't want).
The second section of code is MMDrawerController's setDrawerVisualStateBlock method, which sets the animations code to be performed when a menu is being opened and closed. The first few lines of code are boilerplate code that sets one of the prebuilt animations blocks to each menu (I wanted parallax on the left, but nothing on the right). The relevant code is the last line of the block: [weakSelf.statusBarView setAlpha:percentVisible];, which sets the status bar view's opacity to match the percentage that the menu is currently open. This allows for the smooth cross animation you see in the Facebook app. You'll also notice I've assigned self to a variable weakSelf, so as to avoid the "retain cycle" compiler warning.
This is my specific approach using MMDrawerController and a subclass, which I did more for convenience because I already had the subclass in place, than because it is necessarily the best approach or the only way to do it. It could probably be implemented in several other ways, using MMDrawerController without a subclass, or using any other side-drawer menu implementation.
The ending result is a smooth fading to black animation behind the status bar, exactly as you see in the new Facebook app.
I've been trying to accomplish the same thing. The method I am using to do this is based on the following concepts:
A background image with a height of 64 points will fill both the
UINavigationBar and the UIStatusBar.
A background image with a height of 44 points will fill the UINavigationBar and leave the
UIStatusBar black.
You can add an subview to the top of the current navigationController's view and it will sit underneath the UIStatusBar.
So, first, you need to create two images with your desired UINavigationBar look:
A 640x128px image to cover navigation bar and status bar (ImageA)
And a 640x88px image to cover the navigation bar but leave the status bar black (ImageB).
In the application:didFinishLaunchingWithOptions: method, set the background of your UINavigationBar with ImageA with [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"ImageA.png"] forBarMetrics:UIBarMetricsDefault];
When the side menu starts to open, you are going to want switch the UINavigationBar so it uses ImageB and create a view which you will add underneath the UIStatusBar. Here is some sample code for doing just that:
// Add a property for your "temporary status bar" view
#property (nonatomic, strong) UIView *temporaryStatusBar;
And in the code where the side menu starts to open:
// Create a temporary status bar overlay
self.temporaryStatusBar = [[UIView alloc] initWithFrame:[[UIApplication sharedApplication] statusBarFrame]];
self.temporaryStatusBar.backgroundColor = [UIColor yourColor];
[self.navigationController.view addSubview:self.temporaryStatusBar];
// Update both the current display of the navigationBar and the default appearance values
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"imageB.png"] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:#"imageB.png"] forBarMetrics:UIBarMetricsDefault];
[self.navigationController.navigationBar setNeedsDisplay];
As the side menu animates open, or as the user pans the menu, all you need to do then is adjust the alpha level of the UIStatusBar overlay. When the side menu is fully open, the UINavigationBar should have ImageB as its background image and the UIStatusBar overlay should have an alpha of 0. When the side menu closes, you'll want to replace the UINavigationBar background with ImageA and remove the UIStatusBar overlay.
Let me know if this works for you!
You can use this awesome slide menu library
https://github.com/arturdev/AMSlideMenu
In this demo project you can see how to do that by writing 4 lines of code.
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
// Setting navigation's bar tint color
self.navigationController.navigationBar.barTintColor = [UIColor colorWithHex:#"#365491" alpha:1];
// Making view with same color that navigation bar
UIView *statusBarView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 20)];
statusBarView.backgroundColor = [UIColor colorWithHex:#"#365491" alpha:1];
// Replace status bar view with created view and do magic :)
[[self mainSlideMenu] fixStatusBarWithView:statusBarView];
}
I'm writing an iPhone app with a table inside a navigation controller. When the user clicks one of the cells in the main screen a UIView on top of the incoming view controller is created (it's like a toolbar).
self.toolbar = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 45)];
toolbar.backgroundColor = [UIColor colorWithRed:0.8823 green:0.8823 blue:0.8823 alpha:1.0];
[self.navigationController.view addSubview:toolbar];
The problem is that the view appears before the transition to the new view controller is complete and the effect is pretty weird. I suppose this is due to the fact I add the view to the navigationController,but I need to do this otherwise the bar would scroll together with the table and instead I want it to be fixed.
Any suggestion?
I've found a possible solution: add the toolbar as TableHeaderView and follow iOS: Add UIView to UITableView
Any other better solution is more than welcome
I'm trying to add a Segmented Control to my UIToolbar below, but when I try to drag it over in Storyboard it replaces my Table View.
Also, when I try to add UIBarButton to my Toolbar it pushes my Prototype Cells down... do I have my views hierarchy wrong?
When I add a UIBarButton item anyway, in the simulator the toolbar is not Black Transparent as I set in my navigation control inspector. Whats up with that?
thanks!
To create Segmented Control element in the toolbar with Interface builder it is possible to use the following hint
1) Create Segmented Control Bar Button Item in Navigation Controller:
2) Drag Bar Button Item up to Navigation Item
3) Then you should get the following structure
4) Now you can select Segmented Control to set its properties
1 - Do it programmatically. You need to assign a frame to your UIToolbar first, then you can add elements in it (the segmentedControl). I suggest though to use UIBarButtonItems, which basically are the same.
To stick it to the bottom, try to do this way:
#define SCREEN_FRAME [[UIScreen mainScreen] applicationFrame]
CGRect frame = CGRectMake(0, [[UIScreen mainScreen] bounds].size.height - 44, [[UIScreen mainScreen] bounds].size.width, 44);
UIToolbar *toolBar = [[UIToolbar alloc]initWithFrame:frame];
toolBar.frame = CGRectMake(0,self.view.frame.size.height-toolBar.frame.size.height,SCREEN_FRAME.size.width,toolBar.frame.size.height);
//Setting up the items
UIBarButtonItem *first = [[[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"image.png"] style:UIBarButtonItemStylePlain target:self action:#selector(yourAction:)] autorelease];
UIBarButtonItem *second = [[[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"image.png"] style:UIBarButtonItemStylePlain target:self action:#selector(yourAction:)] autorelease];
//Creating an array with the items
NSArray *items = [NSArray arrayWithObjects:first,second, nil];
//Assigning the array to the toolBar
[toolBar setItems: items];
Then you can set its style with
mytoolbar.barStyle = UIBarStyleBlack;
2 - Same as above, framing.
3 - You need to set your navigationController style to Black.
Use self.navigationController.navigationBar.style = UIBarStyleBlack; ,or in IB choose the buttons and from Inspector set Tint or Style to whatever you want.

I presume there's a navigation view controller somewhere in here. They have their own toolbar, but it's hidden and empty. The toolbar you're seeing is just a simulation of a toolbar for the purpose of letting you edit the UI.
So to do this with storyboard, don't add the segmented control to the simulated toolbar, create a new toolbar and add it to the tree of views available in your controller (as a sibling to your Table View) and create an IBOutlet to reference it. Then in your viewDidLoad method assign the items in the toolbar to the toolbar already created by the view controller.
In this example I've created a property on my view controller called (cunningly) toolbar:
#property (nonatomic, retain) IBOutlet UIToolbar toolbar;
In my view controller's implementation I assign the toolbar items manually:
-(void)viewDidAppear:(BOOL)animated
{
[self setToolbarItems:self.toolbar.items animated:NO];
[self.navigationController setToolbarHidden:NO animated:YES];
}
You'll need to hide the toolbar when the view controller is popped, for instance in the calling view controller:
-(void)viewWillAppear:(BOOL)animated
{
[self.navigationController setToolbarHidden:YES animated:YES];
}
Assuming you want to hide it, of course.
I did this by placing the UISegmentedController in a Bar Button Item.
Add a toolbar to the UINavigationController window, then enable the display of this toolbar on a ViewController screen.
Drag a bar button into the toolbar on the ViewController screen, and drag a UISegmentedController into that (resizing the button to the full width of the screen)
To wire it all up, ctrl-drag from the UISegmentedController to the corresponding .h file, drag from "referencing outlet" to the yellow view controller icon (using the same variable name), then drag from "ValueChanged" to the yellow icon (selecting the method on the controller that you want to call on a new selection).
This all seems to work as expected. (If you can't select a segment on the controller to set an initial value, you didn't connect up the referencing outlet as described above. That stumped me for a little while.)
