Make custom Navigation Buttons glow when touched? - ios

In my navigation bar I have two right button bar items. One is a custom button and the other uses the info light button type. Both work great but I would like to make the custom button have the default glow the same way the info button does when you touch it. Is this possible?
// Default info light btn
UIButton *infoBtn = [UIButton buttonWithType:UIButtonTypeInfoLight];
UIBarButtonItem *infoBtnItem = [[UIBarButtonItem alloc]initWithCustomView:infoBtn];
// Custom Btn
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setFrame:CGRectMake(0, 0, btnImage.size.width, btnImage.size.height)];
[customButton setBackgroundImage:btnImage forState:UIControlStateNormal];
[customButton addTarget:self action:#selector(rightDrawerButtonPress:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customButtonItem = [[UIBarButtonItem alloc] initWithCustomView:wlButton];
NSArray *rightBtns = #[customButtonItem, infoBtnItem];
[navItem setRightBarButtonItems:rightBtns animated:YES];

you just need to put one more line of code like:-
customButton.showsTouchWhenHighlighted = TRUE;
After this your code Output something like this:-

It's hard to click on Bar button Item

I've created custom back bar button. And I added an UIview because I have to change position of it within bar.
UIImage *backButtonImage = [UIImage imageNamed:#"backBtnWhite"];
_backButton = [UIButton buttonWithType:UIButtonTypeCustom];
_backButton.exclusiveTouch = YES;
[_backButton setImage:backButtonImage forState:UIControlStateNormal];
[_backButton setImage:backButtonImage forState:UIControlStateHighlighted];
[_backButton addTarget:self action:#selector(back) forControlEvents:UIControlEventTouchUpInside];
_backButton.frame = CGRectMake(-4.0, 7.0, 40, 40);
UIView * view = [[UIView alloc] initWithFrame:CGRectMake(-4.0, 7.0, backButtonImage.size.width, backButtonImage.size.height)];
[view addSubview:_backButton];
UIBarButtonItem* barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:view];
self.navigationItem.rightBarButtonItem = barButtonItem;
But after that I've added UIView it became difficult to click on it.
I've tried to change button area, but it didn't give results.
It seems like you specify incorrect frame for _button or/and view and this changes the tap region. Try to set different background color for _backButton and view. This will show you if frames are in positions that you expect.
If you try to adjust image position by specifying these frames - its more correct to use properties of UIButton like imageEdgeInsets and titleEdgeInsets.

Highlight UIBarButtonItem like iOS7.1 calendar - already tried setBackgroundImage

I'm trying to make a UIBarButtonItem behave like the "view mode" button in the iOS 7 calendar app. When tapped it becomes highlighted and stays this way until it's tapped again.
Example image (can't embed images yet, sorry)
I have already tried setting the BackgroundImage property to a image with forState:(UIControlStateHighlighted | UIControlStateSelected) as suggested here, nothing happens.
I think you should use a custom view. See this example using a 40x40 button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0,0,40,40);
[button setBackgroundImage:[UIImage imageNamed:#"button.png"] forState:UIControlStateNormal];
[button setBackgroundImage:[UIImage imageNamed:#"buttonSelected.png"] forState:UIControlStateSelected];
[button addTarget:self action:#selector(didTouchButton:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *buttonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:buttonItem, nil]];
And in the touch set selected
- (void) didTouchButton:(id)sender
{
UIButton *button = (UIButton*)sender;
button.selected = YES;
//Do stuff
}

Custom navigation bar back button with only image

I want to show custom navigation bar back button. I want to show only image on it. I want to use this button in whole app also dont want to create this button in each file. How can i??
Here is my code:
// Set the custom back button
UIImage *buttonImage = [UIImage imageNamed:#"back_arrow.png"];
//create the button and assign the image
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(popViewControllerAnimated:) forControlEvents:UIControlEventTouchUpInside];
//create a UIBarButtonItem with the button as a custom view
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationItem.leftBarButtonItem = customBarItem;
but this is showing on current page only.
Another code:
[[UIBarButtonItem appearance] setBackButtonBackgroundImage:[UIImage imageNamed:#"back_arrow.png"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
Using this code back button image is showing in whole app. But the text "Back" is also showing. How can i solve this problem.
Thanks in advance.
I've used a category in the past to do this.
Create a category on UIBarButtonItem called +projectButtons (or something).
Then you can have a function like...
+ (UIBarButtonItem)backArrowButtonWithTarget:(id)target action:(SEL)action
{
UIImage *buttonImage = [UIImage imageNamed:#"back_arrow.png"];
//create the button and assign the image
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:target action:action forControlEvents:UIControlEventTouchUpInside];
//create a UIBarButtonItem with the button as a custom view
UIBarButtonItem *customBarItem = [[UIBarButtonItem alloc] initWithCustomView:button];
return customBarItem;
}
Then add it to you navigation bar like so...
self.navigationItem.leftBarButtonItem = [UIBarButtonItem backArrowButtonWithTarget:self action:#selector(popViewControllerAnimated:)];
This means you only need one line of code to create it but you still get the customisation of the target and action in each VC that you use it in. If you decide to change the look of the button then it's all done in one place.

Info button as UIBarButtonItem doesn't respond to taps

I'm trying to programmatically add and info button to my app's navigation. However, it doesn't ever fire the action that I'm registering to it.
UIBarButtonItem* infoButton =[[UIBarButtonItem alloc] initWithCustomView:[UIButton buttonWithType:UIButtonTypeInfoLight]];
[infoButton setTarget:self];
[infoButton setAction:#selector(infoButtonTapped)];
The button shows up in my nav bar, but clicking on it doesn't pass into infoButtonTapped
Add the target/action to the UIButton. The bar button item behaves differently when it's set up from a UIButton.
UIButton *button = [UIButton buttonWithType:UIButtonTypeInfoLight];
[button addTarget:self action:#selector(infoButtonTapped) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *infoButton = [[UIBarButtonItem alloc] initWithCustomView:button];

UIBarButtonItem Custom view in UINavigationBar

I am making a custom bar buttons for uinavigationbar, I am using following code
UIImageView *backImgView= [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"chk_back.png"]]; [backImgView setUserInteractionEnabled:YES];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:backImgView];
[backButton setTarget:self];
[backButton setAction:#selector(BackBtn)];
checkIn_NavBar.topItem.leftBarButtonItem = backButton;
The problem is it is not calling its action. What i am doing wrong?
From Apple documentation:
Initializes a new item using the specified custom view.
- (id)initWithCustomView:(UIView *)customView
Parameters
customView
A custom view representing the item.
Return Value
Newly initialized item with the specified properties.
Discussion:
The bar button item created by this method does not call the action method of its target in response to user interactions. Instead, the bar button item expects the specified custom view to handle any user interactions and provide an appropriate response.
Solution: "Create button with your background image (set action to this button) and init bar button with this button". For example:
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
btn.frame = CGRectMake(0,0,25,25)
[btn setBackgroundImage:[UIImage imageNamed:#"chk_back.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(BackBtn) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barBtn = [[UIBarButtonItem alloc] initWithCustomView:btn];
I accomplished this using following code:
UIButton *nxtBtn = [UIButton buttonWithType:UIButtonTypeCustom];
[nxtBtn setImage:[UIImage imageNamed:#"chk_next.png"] forState:UIControlStateNormal];
[nxtBtn addTarget:self action:#selector(NextBtn) forControlEvents:UIControlEventTouchUpInside];
[nxtBtn setFrame:CGRectMake(0, 0, 64, 31)];
UIBarButtonItem *nextButton = [[UIBarButtonItem alloc] initWithCustomView:nxtBtn];
checkIn_NavBar.topItem.rightBarButtonItem=nextButton;
