I have an customised UINavigationcontroller created by me programatically.
The Problem is with the back button which comes as a default in UINavigationBar is not seen in IOS6 but when i press it the action can be done.
NOTE: The back button is seen in IOS5.
Here is my code that i had used
- (void)customizeNavigationController:(UINavigationController *)navController
{
UINavigationBar *navBar = [navController navigationBar];
[navBar setTintColor:keyNavBarTintColor];
UIImageView *myImageView = (UIImageView *)[navBar viewWithTag:keyNavBarBackgroundImageTag];
if (myImageView == nil)
{
UIImage *img = [UIImage imageNamed:#"image.png"];
CGRect rect = CGRectMake(0, 0, navBar.frame.size.width, navBar.frame.size.height);
myImageView = [[UIImageView alloc] initWithFrame:rect];
[myImageView setContentMode:UIViewContentModeScaleAspectFill];
[myImageView setAutoresizingMask:UIViewAutoresizingFlexibleWidth];
myImageView.image = img;
[myImageView setTag:keyNavBarBackgroundImageTag];
[navBar addSubview:myImageView];
[myImageView release];
}
self.navImageView = myImageView;
}
Try this:
UIImage *image = [UIImage imageNamed:kButtonBackInActive];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:image forState:UIControlStateNormal];
[button addTarget:self action:#selector(goBack) forControlEvents:UIControlEventTouchUpInside];
[button setFrame:CGRectMake(0, 0, 39.0f, 44.0f)];
button.contentEdgeInsets = (UIEdgeInsets){.left=-8};
button.showsTouchWhenHighlighted = NO;
UIBarButtonItem * backbutton = [[[UIBarButtonItem alloc] initWithCustomView:button] autorelease];
[self.navigationItem setLeftBarButtonItem:backbutton];

I am setting Back and next Button as Navigation Bar item left button and right button.which have code below as
// Back Button
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:#selector(navigatehome)forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = aBarButtonItem;
//Next Button
aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:#selector(navigatenext)forControlEvents:UIControlEventTouchUpInside];
[self.navigationItem setRightBarButtonItem:aBarButtonItem]
And Problem when animated:YES in statement
CSA_info *h1=[[CSA_info alloc]init];
[self.navigationController pushViewController:h1 animated:YES];
It shows as below image
If uses animated:No then showed as below
I am adding a image in as subview in navigation Bar so it hides the buttons.
UIImage *image = [UIImage imageNamed:#"title bar.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(-5, 0, 330, 44);
[self.navigationController.navigationBar insertSubview:imageView atIndex:2];
I required to add that image in navigation.
Why it so, Any Help ?
you need to put title bar image in secondViewcontroller like bellow in ViewDidLoad
UIImage* imageback = [UIImage imageNamed:#"Back_Button.png"];
CGRect frameimgback = CGRectMake(0, 0, 50, 30);
backButton = [[UIButton alloc] initWithFrame:frameimgback];
[backButton setBackgroundImage:imageback forState:UIControlStateNormal];
[backButton addTarget:self action:#selector(Back)
forControlEvents:UIControlEventTouchUpInside];
UIImage *image = [UIImage imageNamed:#"titileBar.png"];
[self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
UIBarButtonItem *btn = [[UIBarButtonItem alloc]initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = btn;
If I understood you problem properly then following solution should work,
You need to add the code in viewDidLoad method of the view controller. Please refer the below code
UIButton *backButton = [[UIButton alloc] initWithFrame:kButtonFrame];
[backButton setImage:[UIImage imageNamed:kBackButtonImage] forState:UIControlStateNormal];
[backButton addTarget:self action:#selector(navigatehome)forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
self.navigationItem.leftBarButtonItem = aBarButtonItem;
UIButton *nextButton = [[UIButton alloc] initWithFrame:kButtonFrame];
[nextButton setImage:[UIImage imageNamed:kNextButtonImage] forState:UIControlStateNormal];
[nextButton addTarget:self action:#selector(navigatenext)forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *aBarButtonItemRight = [[UIBarButtonItem alloc] initWithCustomView:nextButton];
[self.navigationItem setRightBarButtonItem:aBarButtonItemRight];
This should work fine even you animated while pushing the view controller.
I want to change the backbutton appearance for my backbutton in my navigation bar. For that I have this piece of code.
UIImage *backButtonImage = [UIImage imageNamed:#"backbutton.png"];
UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
backbutton.backgroundColor = [UIColor colorWithPatternImage:backButtonImage];
backbutton.titleLabel.text = #"back";
backbutton.titleLabel.textColor= [UIColor colorWithRed:50/255.0
green:158/255.0
blue:218/255.0
alpha:1.0];
backbutton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
UIBarButtonItem * back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
[backbutton addTarget:self action:#selector(back_Clicked) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = back;
But still I get the standard back button. Any help ?
Put your code to customize back button before pushing that viewController to the stack. And set BackBarButtonItem , not leftBarButtonItem.
UIImage *image = [UIImage imageNamed:#"backbutton.png"];
UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
backbutton.bounds = CGRectMake( 0, 0, image.size.width, image.size.height );
[backbutton setImage:image forState:UIControlStateNormal];
backbutton.titleLabel.textColor = [UIColor blueColor];
UIBarButtonItem *back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
[[self navigationItem] setBackBarButtonItem: back];
[self.navigationController pushViewController:yourViewControllerObject animated:YES];
using bellow code for your requirement..
- (void)viewDidLoad
{
///write your code
UIImage *backButtonImage = [UIImage imageNamed:#"backbutton.png"];
UIButton *backbutton = [UIButton buttonWithType:UIButtonTypeCustom];
//[backbutton setImage:backButtonImage forState:UIControlStateNormal];//this line for set only image on button
[backbutton setBackgroundImage:backButtonImage forState:UIControlStateNormal];
[backbutton setTitle:#"Back" forState:UIControlStateNormal];
backbutton.frame = CGRectMake(0, 0, backButtonImage.size.width, backButtonImage.size.height);
UIBarButtonItem * back = [[UIBarButtonItem alloc] initWithCustomView:backbutton];
[backbutton addTarget:self action:#selector(back_Clicked) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.leftBarButtonItem = back;
}
when back button clicked bellow method call and you will go to previous viewcontroller
-(void)back_Clicked{
[self.navigationController popViewControllerAnimated:YES];
}
Use
self.navigationItem.leftBarButtonItem = back;
Instead of
self.navigationController.navigationItem.leftBarButtonItem = back;
[self.navigationItem setLeftBarButtonItem:[[UIBarButtonItem alloc] initWithCustomView:[self buttonWithImage:#"backButton" heighlightImageName:#"backButton" buttonFrame:CGRectMake(2, 1, 30, 30) selectorName:#selector(buttonBackClicked:) target:self]]];
- (UIButton*)buttonWithImage:(NSString*)normalImageName heighlightImageName:(NSString*)heighlightImageName buttonFrame:(CGRect)buttonFrame selectorName:(SEL)selectorName target:(id)target
{
UIButton *tempButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[tempButton setFrame:buttonFrame];
[tempButton addTarget:target action:selectorName forControlEvents:UIControlEventTouchUpInside];
[tempButton setImage:[self getImageFromResource:normalImageName] forState:UIControlStateNormal];
[tempButton setImage:[self getImageFromResource:heighlightImageName] forState:UIControlStateHighlighted];
return tempButton;
}
- (UIImage*)getImageFromResource:(NSString*)imageName
{
return [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:imageName ofType:#"png"]];
}
IButton *favButton = [[UIButton alloc] init];
[favButton setImage:[UIImage imageNamed:#"unselected.png"] forState:UIControlStateNormal];
[favButton addTarget:self action:#selector(favouriteButtonClicked:)
forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *button = [[UIBarButtonItem alloc]
initWithCustomView:favButton];
self.navigationItem.rightBarButtonItem = button;
[button release];
[favButton release];
I have a detailview with a navigation bar with a back button and a name for the view.
The navigation bar is set programmatically.
The name presented is set like this.
self.title = NSLocalizedString(name, #"");
The name depends on the presented view.
Now I would like to also present a small icon on the navigation bar which also is depends on the view.
How do I do that?
You can set backGround image to navigationBar Using this
Put in didFinishLaunchingWithOptions
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:#"title_bar.png"] forBarMetrics:UIBarMetricsDefault];
Or you can set navigation bar image in any view using
UINavigationBar *navBar = [[self navigationController] navigationBar];
UIImage *image = [UIImage imageNamed:#"TopBar.png"];
[navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
Or you can set a view on your NavigationBar Link
[[UINavigationBar appearance] addSubview:yourView];
or
self.navigationItem.titleView = YourView;
And set title using h
self.navigationItem.title = #"Your Title";
And you can get navigationBarButton using this
-(void)getRightBarBtn
{
UIButton *Btn =[UIButton buttonWithType:UIButtonTypeCustom];
[Btn setFrame:CGRectMake(0.0f,0.0f,68.0f,30.0f)];
[Btn setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:#"yourImage.png"]] forState:UIControlStateNormal];
//[Btn setTitle:#"OK" forState:UIControlStateNormal];
//Btn.titleLabel.font = [UIFont fontWithName:#"Georgia" size:14];
[Btn addTarget:self action:#selector(yourBtnPress:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithCustomView:Btn];
[self.navigationItem setRightBarButtonItem:addButton];
}
And set simple imageView on navigation Bar
UIImageView *image = [[UIImageView alloc]initWithImage:[UIImage imageNamed:#"star.png"]];
UIBarButtonItem *backBarButton = [[UIBarButtonItem alloc] initWithCustomView:image];
self.navigationItem.rightBarButtonItem = backBarButton;
You need to subclass UINavigationBar. Then in drawRect do something like:
[[UIImage imageNamed...] drawInRect:...]
and call the super method ofcourse
Add this code into viewDidLoad in your ViewController:
UIImage *image = [UIImage imageNamed: #"myIcon.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
imageView.frame = CGRectMake(5, 2, 100, 39);
[self.navigationController.navigationBar addSubview:imageView];
imageView can also be declared as an instance variable, so you can access it after you've added it (e.g. if you want to remove your icon from your navigationBar at some point).
UIButton *homeBtn=[[UIButton alloc] initWithFrame:CGRectMake(0, 0, 46, 28)];
[homeBtn setBackgroundImage:[UIImage imageNamed:#"homeBtn.png"] forState:UIControlStateNormal];
[homeBtn addTarget:self action:#selector(homeBtnPressed) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *navHomeBtn=[[[UIBarButtonItem alloc] initWithCustomView:homeBtn] autorelease];
self.navigationItem.rightBarButtonItem=navHomeBtn;
[homeBtn release];
I have a custom bar button item that I want to nudge down 5 pixels. How would I go about doing that witht the following code. I tried to set the "y" point but keep getting syntax errors.
[self.navigationController setNavigationBarHidden:NO animated:YES];
UIImage *image = [UIImage imageNamed:#"arrow_back.png"];
UIImageView *imageView = [[UIImageView alloc] initWithImage:image];
[self.navigationController.navigationBar addSubview:imageView];
[imageView release];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:buttonImage forState:UIControlStateNormal];
//set the frame of the button to the size of the image (see note below)
button.frame = CGRectMake(0, 0, buttonImage.size.width, buttonImage.size.height);
[button addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside];
//create a UIBarButtonItem with the button as a custom view
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = customBarItem;
[customBarItem release];
}
thanks for any help
A UIBarButton item doesn't inherit from UIView so doesn't have a "frame" property that you can adjust directly so you need to use a different method.
Try:
[self.navigationItem.leftBarButtonItem setBackgroundVerticalPositionAdjustment:5 forBarMetrics:UIBarMetricsDefault];
I can't set full image in navigation bar (or navigation controller ,in the top of app). there will be little space remaining in the left.And when I put info button it's not on the image. How can I fix it
here is my code,pls take a look
UIImageView* img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"headerBG.png"]];
img.frame = CGRectMake(0, 0, 320, 44);
self.navigationItem.titleView =img;
[img release];
UIButton * infoDarkButtonType = [[UIButton buttonWithType:UIButtonTypeInfoLight] retain];
infoDarkButtonType.frame = CGRectMake(0.0, 0.0, 25.0, 25.0);
infoDarkButtonType.backgroundColor = [UIColor clearColor];
[infoDarkButtonType addTarget:self action:#selector(showInfo) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *infoButton = [[UIBarButtonItem alloc] initWithCustomView:infoDarkButtonType];
self.navigationItem.leftBarButtonItem = infoButton;
[infoDarkButtonType release];
[infoButton release];
very thank you.
Me.
If you want the navigation bar to show an image cant you try this
#implementation UINavigationBar (CustomImage)
- (void)drawRect:(CGRect)rect
{
UIImage *image = [UIImage imageNamed: #"custom_nav_bar.png"];
[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
}
#end
Use this code line ot add image in NavigationController...
UIImageView* img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"headerBG.png"]];
img.frame = CGRectMake(0, 0, 320, 44);
[self.navigationController.navigationItem addSubView:img];
[img release];
now, you set image in Navigation..
