UINavigationController centered button using obj-c - ios

I'm trying to add a centered button in my navbar header, confused as to how I can do it
- (void)viewDidLoad {
[super viewDidLoad];
UIImage *meImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:#"%#/me.png", kSelfBundlePath]];
UIBarButtonItem *meButton = [[UIBarButtonItem alloc] initWithImage:meImage style:UIBarButtonItemStylePlain target:self action:#selector(twitterButton)];
[self.titleView //i read this can be used to like set it but i havent been able to figure it out
help would be appreciated, pretty new

check this code
UIView *container = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
container.backgroundColor = [UIColor clearColor];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 44, 44)];
[btn setBackgroundImage:[UIImage imageNamed:#"button0.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(btnAction:) forControlEvents:UIControlEventTouchUpInside];
[btn setShowsTouchWhenHighlighted:YES];
[buttonContainer addSubview:button0];
//add your spacer images and button1 and button2...
self.navigationItem.titleView = container;

You can try like this way
UIView *topView = [[UIView alloc]initWithFrame:CGRectZero];
UIButton * button = [[UIButton alloc]initWithFrame:CGRectZero];
[button addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Title here" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button sizeToFit];
[topView addSubview:button];
[topView sizeToFit];
self.navigationItem.titleView = topView;
-(void)buttonAction:(Id) sender {
NSLog(#"button clicked");
}

I think its pretty straight, you can use titleView property of UINavigationItem :
-(void)addCenterButton {
UIImage *meImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:#"%#/me.png", kSelfBundlePath]];
UIButton *button = [[UIButton alloc] initWithFrame::CGRectMake(0, 0, 40, 20)];
[button setImage:meImage forState:UIControlStateNormal];
[button addTarget:self action:#selector(twitterButton) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.titleView = button;
}

How to cancel UIBarbuttonItem setTitle shining effect

Like image shows, I used UIBarbuttonItem as rightBarButtonItem, what I want to do is just change rightBarButton's title when I select a picture or deselect a picture, so I used code like this:
[self.rightBarButton setTitle:[NSString stringWithFormat:#"完成(%#/%#)",#(_selectedAssets.count),#(self.maxPicturesNum)]];
but the barbutton will show shin when its text changed, I try to use UIButton instead of UIBarButtonItem, and shin effect disappear indeed, but UIButton will be close to right bounds far, can you help me?
You can create UIButton and assign it to your rightBarButton
UIButton *rightButton = [[UIButton alloc] initWithFrame:someFrame];
[rightButton setBackgroundImage:someImage forState:UIControlStateNormal];
[rightButton addTarget:self action:#selector(back:) forControlEvents:UIControlEventTouchUpInside];
rightButton.titleLabel.text = [NSString stringWithFormat:#"完成(%#/%#)",#(_selectedAssets.count),#(self.maxPicturesNum)];
rightButton.titleLabel.font = someFont;
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightButton];
self.rightBarButton = rightBarButtonItem;
And while updating label use rightButton.titleLabel.text
For Adjusting label use this:
- (void)setTitlePositionAdjustment:(UIOffset)adjustment
forBarMetrics:(UIBarMetrics)barMetrics
Finally,I do like this:
- (void)loadRightButtonItem{
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(30, 0, 120, 40);
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentRight;
[button setTitle:#"完成(0/9)" forState:UIControlStateNormal];
button.tintColor = [UIColor whiteColor];
[button setTitleShadowColor:[UIColor whiteColor] forState:UIControlStateHighlighted];
// [button setTitleColor:[self.buttonFolder titleColorForState:UIControlStateHighlighted] forState:UIControlStateHighlighted];
[button addTarget:self action:#selector(onFinishClicked:) forControlEvents:UIControlEventTouchUpInside];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 135, 40)];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:view];
[view addSubview:button];
self.navigationItem.rightBarButtonItem = item;
_rightBarButton = button;
}
It cancel the shin effect.
thanks to #RoHaN,your idea did great inspired me.

Space between uibarbuttons in navigation bar, Xcode 6.1

I have tried almost all answers here, How to remove the blank space between the two uibarbuttons shown below the code i use is
UIButton *backBTN= [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
[backBTN addTarget:self action:#selector(backACT:) forControlEvents:UIControlEventTouchUpInside];
[backBTN setBackgroundImage:[UIImage imageNamed:#"menu_icon.png"] forState:UIControlStateNormal];
UIBarButtonItem *backkb = [[UIBarButtonItem alloc] initWithCustomView:backBTN];
// self.navigationItem.leftBarButtonItem = backkb;
UIButton *homeBTN= [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
[homeBTN addTarget:self action:#selector(homeACT:) forControlEvents:UIControlEventTouchUpInside];
[homeBTN setBackgroundImage:[UIImage imageNamed:#"logout_btn.png"] forState:UIControlStateNormal];
UIBarButtonItem *btnhome = [[UIBarButtonItem alloc] initWithCustomView:homeBTN];
// btnhome.imageInsets = UIEdgeInsetsMake(-10, 0, 0, 0);
[self.navigationItem setLeftBarButtonItems:[NSArray arrayWithObjects: backkb, btnhome, nil]];
self.navigationItem.hidesBackButton = YES;
Try this,
// Create a UIView to add both buttons
UIView *leftView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 60, 30)];
UIButton *backBTN= [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 30, 30)];
[backBTN addTarget:self action:#selector(backACT:) forControlEvents:UIControlEventTouchUpInside];
[backBTN setBackgroundImage:[UIImage imageNamed:#"menu_icon.png"] forState:UIControlStateNormal];
//Add button to UIView
[leftView addSubview:backBTN];
UIButton *homeBTN= [[UIButton alloc] initWithFrame:CGRectMake(30, 0, 30, 30)];
[homeBTN addTarget:self action:#selector(homeACT:) forControlEvents:UIControlEventTouchUpInside];
[homeBTN setBackgroundImage:[UIImage imageNamed:#"logout_btn.png"] forState:UIControlStateNormal];
//Add button to UIView
[leftView addSubview:homeBTN];
//Set UIView as CustomView for bar button
UIBarButtonItem *leftBarButton = [[UIBarButtonItem alloc] initWithCustomView:leftView];
[self.navigationItem setLeftBarButtonItems:[NSArray arrayWithObjects: leftBarButton, nil]];
self.navigationItem.hidesBackButton = YES;
I have tried this and got output as
used some background colour to know the borders

Customize navigation bar button in iOS6

Update - One Possible Solution
Based on answer given by Alexander Merchi in this post (UIBarButtonItem Custom view in UINavigationBar), a solution is found. But still don't know how to change the position of the image properly.
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 28.0f, 28.0f)]; // 28 points is the width or height of the button image
[btn setBackgroundImage:[UIImage imageNamed:#"button.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(onClickMenuButton) forControlEvents:UIControlEventTouchUpInside];
btnMenu = [[UIBarButtonItem alloc] initWithCustomView:btn];
Original Post
In iOS 6, the goal is like this:
while current result is like this:
My code is
btnMenu = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"button.png"]
style:UIBarButtonItemStylePlain
target:self
action:#selector(onClickMenuButton)];
button.png is this the white circle with white three bars inside and a tranparent background.
UIButton *rightButton = [UIButton buttonWithType:UIButtonTypeCustom];
rightButton.frame = CGRectMake(0, 0, 30, 30);
[rightButton setImage:[UIImage imageNamed:#"Button-normal"] forState:UIControlStateNormal];
[rightButton setImage:[UIImage imageNamed:#"logout-hover"] forState:UIControlStateHighlighted];
[rightButton addTarget:self action:#selector(logOut) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightButton];
self.navigationItem.leftBarButtonItem = rightBarButtonItem;
I am accomplishing it by
UIImageView *uView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"btn_back_ontouch_scr11.png"]];
UIButton *leftButton = [UIButton buttonWithType:UIButtonTypeCustom];
leftButton.bounds = CGRectMake( 0, 0, uView.frame.size.width, uView.frame.size.height );
[leftButton setImage:uView.image forState:UIControlStateHighlighted];
[leftButton setImage:[UIImage imageNamed:#"btn_back_normal_scr11.png"]forState:UIControlStateNormal];
[leftButton addTarget:self.navigationController action:#selector(popViewControllerAnimated:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *aButton = [[UIBarButtonItem alloc] initWithCustomView:leftButton];
self.scrollView.indicatorStyle=UIScrollViewIndicatorStyleWhite;
self.navigationItem.leftBarButtonItem = aButton;
self.navigationItem.hidesBackButton = YES;
This should work.

Adding custom back button on navigation bar

I am trying to add custom back button on navigation bar but it is not working below is my code
-(void)addLeftButton
{
UIImage *buttonImage = [UIImage imageNamed:#"btn_back.png"];
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aButton setBackgroundImage:buttonImage forState:UIControlStateNormal];
aButton.frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height);
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.backBarButtonItem = aBarButtonItem;
}
Please tell what's wrong with this code
Try this.
-(void)addLeftButton
{
UIImage *buttonImage = [UIImage imageNamed:#"btn_back.png"];
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aButton setBackgroundImage:buttonImage forState:UIControlStateNormal];
aButton.frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height);
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:nil forControlEvents:UIControlEventTouchUpInside];
[self.navigationItem setLeftBarButtonItem:aBarButtonItem];
}
Here is the code that i have used to create custom backbutton
- (void)viewDidLoad
{
[super viewDidLoad];
// Set the custom back button
//add the resizable image
UIImage *buttonImage = [[UIImage imageNamed:#"backbtn.png"]
resizableImageWithCapInsets:UIEdgeInsetsMake(0, 13, 0, 5)];
//create the button and assign the image
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:buttonImage forState:UIControlStateNormal];
MSLabel *lbl = [[MSLabel alloc] initWithFrame:CGRectMake(12, 4, 65, 28)];
lbl.text = #"Settings";
lbl.backgroundColor = [UIColor clearColor];
//lbl.font = [UIFont fontWithName:#"Helvetica" size:12.0];
lbl.numberOfLines = 0;
lbl.lineHeight = 12;
lbl.verticalAlignment = MSLabelVerticalAlignmentMiddle;
lbl.font = [UIFont fontWithName:#"Helvetica" size:12];
[button addSubview:lbl];
//set the frame of the button to the size of the image (see note below)
button.frame = CGRectMake(0, 0, 70, 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;
}
-(void)back {
// Tell the controller to go back
[self.navigationController popViewControllerAnimated:YES];
}
This code will resize your image so it can fit the text.
You can also put this button in any method.
You didn't add action to your button. So you need to add action to your button. For more info see in the below code..
-(void)addLeftButton
{
UIImage *buttonImage = [UIImage imageNamed:#"btn_back.png"];
UIButton *aButton = [UIButton buttonWithType:UIButtonTypeCustom];
[aButton setBackgroundImage:buttonImage forState:UIControlStateNormal];
aButton.frame = CGRectMake(0.0, 0.0, buttonImage.size.width, buttonImage.size.height);
UIBarButtonItem *aBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:aButton];
[aButton addTarget:self action:#selector(backBtnPressed) forControlEvents:UIControlEventTouchUpInside]; // -------- Edit here -----
self.navigationItem.backBarButtonItem = aBarButtonItem;
}
-(void)backBtnPressed
{
[self.navigationController popViewControllerAnimated:YES];
}
