I have added UISearchBar to UINavigationBar and this works really well, Except the left padding of UISerachBar here.
On Debug I came to know that here back button frame is too large that's why UINavigation bar title view shifted from left too much.
How to deal with that?
I want to achieve something like twitter app where the spacing between back button and search bar is not much.
Thanks in advance!
You can add a custom back button in your navigation bar to override the default back button (in this case the left button):
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"my-back-button-image.png"]];
imageView.frame = CGRectMake(0, 0, 43, 30);
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:imageView];
self.navigationItem.leftBarButtonItem = barButtonItem;
The space between left button and search controller decreases.
As mentioned earlier by Michele Broggi you can try that.
Else
You can also set the search Bar in place of navigation Title view so that it would be centre aligned to the screen (If you want that design)

-(void)imageFullScreen:(UITapGestureRecognizer*)sender{
modalCon = [[UIViewController alloc] init];
modalCon.view.backgroundColor=[UIColor blackColor];
modalCon.view.userInteractionEnabled=YES;
UIImageView *imageView = [[UIImageView alloc] initWithFrame:modalCon.view.frame];
imageView.contentMode = UIViewContentModeScaleAspectFit;
imageView.image = self.mImageView.image;
[modalCon.view addSubview:imageView];
UITapGestureRecognizer *modalTap =[[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(dismissModalView:)];
[modalCon.view addGestureRecognizer:modalTap];
[self.delegate showFullScreen:modalCon];
return;
}
The method showFullScreen:modalCon will show the modalViewController(modalCon) and on touch of image shown, it will dismiss. But when image is full screen, the navigation bar is not shown (black bars come both above and below the image) like this:
But I want same behaviour as iOS photos app does on click of any photo in library where a navigation bar comes up and tool bar down with multiple buttons comes and edit, back, share, delete options come like this :

Create a view from storyboard
Embedded it with navigation bar
Setup title and edit button in viewcontroller file
Add image view and and uiview
UIview contains tableview and the 3 buttons
table view you have to manage scroll and frame programatically
I'm using a UISearchController in iOS 8 and when I make its UISearchBar my table's header view everything is fine. However now I need it in my UINavigationBar's left bar button (can't be the title view because of the vertical centering when I enlarge the nav bar). When I wrap the UISearchBar in a UIBarButtonItem it is larger than the width of the screen.
I think it is related to my view controller initialized from a storyboard with size classes enabled which means my frames are not set till viewDidLayoutSubviews. However I had the same issue with my segmented control in a toolbar and I just called sizeToFit on the toolbar in viewDidLayoutSubviews and that fixed the toolbar. When I do the same for the search bar it still draws partly off screen. Apple does this in some of their iPad apps but how?
Note: I can hack it to get it all on screen but I have to wrap it in another view but then the color is off and it just seems wrong and I think the animation is off.
You need to create a UIBarButtonItem with UIBarButtonSystemItemFixedSpace with -10 width which will remove 10 px padding.
UIBarButtonItem *Spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[Spacer setWidth:-10];
UISearchBar *searchBar= [[UISearchBar alloc] initWithFrame:CGRectMake(0, 5, self.view.frame.size.width-10, 39)];
UIBarButtonItem *searchBarItem = [[UIBarButtonItem alloc] initWithCustomView:searchBar];
self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:Spacer,searchBarItem,nil];
I have searched lots for how to design navigation like given in the image.
I have created category for UINavigationBar like given in the following solution
Custom nav bar styling - iOS
Able to increase the size of NavigationBar using below code.
CGFloat navBarHeight = 84.0f;
CGRect frame = CGRectMake(0.0f, 0.0f, 320.0f, navBarHeight);
[self.navigationController.navigationBar setFrame:frame];
But all content like (left button, right button, title) moves to bottom of bar.
When attach segment control to titleView like below
self.navigationItem.titleView = self.segmentedControl;
All views( left button, title, right button) as liner.
I want segment control bottom of the navigation bar as shown in the image.
#Shankar Shinde why are you adding segment controller as navigation title view you can add below the navigation bar using storyboard: check below screen shot
I think you need to hide the navigation bar using following code and create view like attached screenshot let me know it's help you or not ?
[self.navigationController.navigationBar setHidden:YES];
Please check it out sample:

It may help you :)
You can use Prompt provided for navigationItem
First give prompt to your navigationItem
self.navigationItem.prompt = #"";
Create a segmentcontroll
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(35, 200, 250, 50);
segmentedControl.segmentedControlStyle = UISegmentedControlStylePlain;
segmentedControl.selectedSegmentIndex = 1;
[self.navigationController.navigationBar addSubview:segmentedControl];
I currently have a button image for the leftBarButton of the UINavigationBar. Is there a way to eliminate the space between this button and the left edge of the UINavigationBar? I thought about just making a custom image for the background of the UINavigationBar, but I want to be able to use the back buttons that are generated on other screens. Ideas?
The layout logic of the navigation bar itself is going to want to try to maintain that space on the left side.
You could try specifying a custom view when setting the navigation items (UIBarButtonItem initWithCustomView:), and pass in a view with a negative x origin -- but I assume the navigation bar would ignore any such origin. (You could also try to keep a reference to that view, and move it to the left after the navigation bar finishes its layout)
Another option would be to try to create your own custom navigation bar -- possibly by putting a custom view in the center of the navigation bar, and stretching it to cover the width & height of the bar.
Try this, it works for me:
CGRect frame = self.navigationController.navigationBar.frame;
frame.origin.x = -10;
self.navigationController.navigationBar.frame = frame;
Basically, set the navigation bar x coordinate to negative not the bar item.
in ios7 you can just add a dummy barbuttonitem
for fixing left space you should add dummy as first, for right as last
example for left, you should add this after setting your original items or in viewdidload if you are setting buttons using storyboard.
NSMutableArray *buttons = [[NSMutableArray alloc] init];
UIBarButtonItem *spacerItem = [[UIBarButtonItem alloc] init];
[buttons addObject:spacerItem];
for(UIBarButtonItem *item in self.leftBarButtonItems){
[buttons addObject:item];
}
[self setLeftBarButtonItems:[NSArray arrayWithArray:buttons] animated:NO];
I wanted to have two buttons on the both end of Navigation Bar (in iPad's Detail View Controller).
So I created two UIToolbars and I set the them as Left&RightBarButtonItems.
But, There is some color variation in the NavigationBar.
Attached images for your understanding.
the code I used ,
UIToolbar *leftToolbar =[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 200, 45)];
NSMutableArray *lItems = [[NSMutableArray alloc] initWithArray:[leftToolbar items]];
UIBarButtonItem *lb1 =[[UIBarButtonItem alloc]initWithTitle:#"Home"style:UIBarButtonItemStyleBordered target:self action:#selector(home:) ];
UIBarButtonItem *lb2 =[[UIBarButtonItem alloc]initWithTitle:#"New Document"style:UIBarButtonItemStyleBordered target:self action:#selector(newDoc:) ];
[lItems insertObject:lb1 atIndex:0];
[lItems insertObject:lb2 atIndex:1];
[leftToolbar setItems:lItems animated:YES];
[lItems release];
leftToolbar.barStyle =UIBarStyleBlackTranslucent;
leftToolbar.tintColor=[UIColor clearColor];
self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc] initWithCustomView:leftToolbar];
Can you help me to avoid this color variation?
Is there any other way to have buttons like this, without using UIToolbar?
Thanks ,
Gopi.
just remove navigation bar and add tool bar, why you adding toolbar to navigation bar?
To achieve the same, use segment controll, set it in Left or right barbutton's view, once you select a segmet, deselect it after few seconds, say 0.3secs, it looks good, no color vairations, it looks like a part of Navigation bar
Found the solution !
code is correct, but one small bug. Have to set the height to 44, not 45. I did this and it seems to fit over the existing NavigationBar.
UIToolbar *leftToolbar =[[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
Works for me . . Anyway I moved to the Single tool bar method.
Hope this helps some one.!!
Have a great day!!
Gopi.
