I have UISegmentedControl on toolbar, when I add custom background drawing method for toolbar segmented control moved nearly 2px down, so it is not vertically centered. Here is corresponding image link, see toolbar on the bottom of the screenshot and code how I've added segmented control to toolbar:
segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentedItems];
[segmentedControl addTarget:self action:#selector(tabChanged:) forControlEvents:UIControlEventValueChanged];
UIBarButtonItem *button1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
button1.style = UIBarButtonItemStylePlain;
UIBarButtonItem *button2 = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
button2.width = kSegmentedControlFrame.size.width;
button2.style = UIBarButtonItemStylePlain;
UIBarButtonItem *button3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
button3.style = UIBarButtonItemStylePlain;
CGFloat y = self.contentView != nil ? self.contentView.frame.origin.y + self.contentView.frame.size.height : kToolbarFrame.origin.y;
UIToolbar *t = [[[UIToolbar alloc] initWithFrame:CGRectMake(kToolbarFrame.origin.x, y,
kToolbarFrame.size.width, kToolbarFrame.size.height)] autorelease];
[t setItems:[NSArray arrayWithObjects:button1, button2, button1 , nil]];
t.clipsToBounds = NO;
t.autoresizesSubviews = YES;
t.clearsContextBeforeDrawing = NO;
t.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleWidth
| UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin;
t.barStyle = UIBarStyleDefault;
t.tintColor = [UIColor clearColor];
t.contentMode = UIViewContentModeScaleToFill;
t.backgroundColor = [UIColor clearColor];
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.tintColor = [ColorUtil colorWithRed:129 withGreen:167 withBlue:186];
segmentedControl.frame = kSegmentedControlFrame; //CGRectMake(kSegmentedControlFrameX, kSegmentedControlY, kSegmentedControlWidth, kSegmentedControlHeight);
segmentedControl.selectedSegmentIndex = 0;
segmentedControl.contentVerticalAlignment = UIControlContentVerticalAlignmentTop;
segmentedControl.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
segmentedControl.clipsToBounds = NO;
segmentedControl.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleBottomMargin;
segmentedControl.center = CGPointMake(160, 22);
segmentedControl.momentary= NO;
[button1 release];
[button2 release];
[button3 release];
return t;
Thanks in advance,
Naira
Is it possible that the toolbar is extending off the bottom of the screen, so that the segmented controller only appears closer to the bottom? There's no clear guard here against having a content view and toolbar size that together are taller than the visible screen area. Try positioning it with an origin.y value that is something along the lines of
CGFloat y = self.view.bounds.size.height - kToolbarFrame.size.height;

I am attempting to set a label into a subclassed UIToolBar. I am first creating the label, then converting it to a UIBarButtonItem and setting them to the toolbar, but the toolbar just appears blank.
here is my code in my init method of my subclassed toolbar
NSMutableArray *items = [[NSMutableArray alloc] init];
// prep the total label
_totalLabel = [[UILabel alloc] init];
_totalLabel.font = [_totalLabel.font fontWithSize:15];
_totalLabel.textColor = [UIColor whiteColor];
_totalLabel.text = NSLocalizedString(#"TOTAL", nil);
_totalLabel.frame = CGRectMake(0, 0, 100, 44);
_totalLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleTopMargin;
_totalLabel.layer.borderWidth = 2;
_totalLabel.layer.borderColor = [UIColor greenColor].CGColor;
_totalLabel.backgroundColor = [UIColor clearColor];
UIBarButtonItem *spacer2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[items addObject:spacer2];
UIBarButtonItem *total = [[UIBarButtonItem alloc] initWithCustomView:_totalLabel];
[items addObject:total];
[self setItems:items];
any idea whats wrong?
Where are you calling this code from? If you have it in initWithFrame: or initWithCoder: it will not work.
Try this:
- (void)layoutSubviews {
[super layoutSubviews];
if(self.items.count == 0) {
//Your code here
}
}
That will get it working. The question is though should you be doing this in layoutSubviews? Probably not. You could also put a setup method on your UIToolbar and call that at a later point in your application.
This is not a uitoolbar. this is a navigation bar so please remove navigationbar and add toolbar . Try this type .
I need it aligned to left. Or there is no way and I need to add custom label?
Add it to the left button item:
UIView *mCustView = [[UIView alloc] initWithFrame:CGRectMake(0,0,200,20)];
mCustView.backgroundColor = [UIColor redColor];
UILabel *mTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0,200,20)];
mTextLabel.backgroundColor = [UIColor blueColor];
mTextLabel.font = [UIFont systemFontOfSize:20];
mTextLabel.textColor = [UIColor blackColor];
mTextLabel.text = #"Random text tested here, so sit back and enjoy";
[mCustView addSubview:mTextLabel];
[mTextLabel release];
UIBarButtonItem *mCustomBarItem = [[UIBarButtonItem alloc] initWithCustomView:mCustView];
self.navigationItem.leftBarButtonItem = mCustomBarItem;
[mCustView release];
You need to add a custom view to the navigation bar's -titleView
self.navigationItem.titleView = someLabel;
I think you could use UIBarButtonSystemItemFixedSpace which provides a way of adding a fixed padding in a navigation bar:
UIBarButtonItem *fixedSpaceItem = [[[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil
action:NULL]
autorelease];
fixedSpaceItem.width = 50;
UIBarButtonItem *cancelItem = [[[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:nil
action:NULL]
autorelease];
// vc is some view controller
vc.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:
fixedSpaceItem,
cancelItem,
nil];
This will right indent the "Cancel" button 50 points.
I have found the solution by myself:
float offset = 210.0f;
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, offset, 44.01)];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
I have a UINavigationBar and have the leftBarButtonItem and rightBarButtonItem set. The leftbar is set as:
UIButton *backButton = [UIButton buttonWithType:UIButtonTypeCustom];
[backButton setImage:[UIImage imageNamed:#"back.png"] forState:UIControlStateNormal];
UIBarButtonItem *myButton = [[[UIBarButtonItem alloc] initWithCustomView:backButton] autorelease];
self.navigationItem.leftBarButtonItem = myButton;
and the rightbarbutton is set as:
UIButton *doneBtn = [UIButton buttonWithType:UIButtonTypeCustom];
UIImage *doneButtonImage = nil;
doneButtonImage = [UIImage imageNamed:#"done.png"];
[doneBtn setImage:doneButtonImage forState:UIControlStateNormal];
doneBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:doneBtn];
self.navigationItem.rightBarButtonItem = doneBarButtonItem;
the width of back is 23px and done is 72px, so they're not equal. Now the issue is I have a label that I want to be in the center all the time.. and I want to clip the text if the text in the label is too long that it interferes with the right bar button. here's how I set it up:
titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
titleLabel.text = self.pageTitle; // Can't change
titleLabel.adjustsFontSizeToFitWidth = YES;
titleLabel.clipsToBounds = YES;
titleLabel.numberOfLines = 1;
titleLabel.font = [UIFont fontWithName:#"PTSans-Narrow" size:30.0];
titleLabel.textColor = [UIColor colorWithWhite:0.6 alpha:1.0];
titleLabel.backgroundColor = [UIColor yellowColor];
titleLabel.autoresizingMask = UIViewAutoresizingFlexibleHeight;
titleLabel.textAlignment = UITextAlignmentCenter;
[titleLabel sizeToFit];
titleLabel.frameHeight = self.navigationController.navigationBar.frameHeight;
self.navigationItem.titleView = titleLabel;
However this doesn't center the title.. How can I do so?
I suggest first count the width of self.pageTitle
then accordingly set the position of titleLabel.I prefer this:-
titleLabel = [[UILabel alloc] init];
titleLabel.text = self.pageTitle; // Can't change
**CGSize maximumTitleLabelSize = CGSizeMake(200,40);//Set maximum width that an self.pageTitle can have.
CGSize expectedLabelSize = [titleLabel.text titleLabel.font
constrainedToSize:maximumTitleLabelSize
lineBreakMode:UILineBreakModeWordWrap];
//adjust the label the the new width.
CGRect newFrame = titleLabel.frame;
newFrame.size.width = expectedLabelSize.width;
titleLabel.size.width = newFrame.size.width;**
if(titleLabel.size.width==100)
{
titleLabel.frame = cgRectMake(85,5,titleLabel.size.width,30);
}
else if(titleLabel.size.width==200)
{
titleLabel.frame = cgRectMake(36,5,titleLabel.size.width,30);
}
titleLabel.adjustsFontSizeToFitWidth = YES;
titleLabel.clipsToBounds = YES;
titleLabel.numberOfLines = 1;
titleLabel.font = [UIFont fontWithName:#"PTSans-Narrow" size:30.0];
titleLabel.textColor = [UIColor colorWithWhite:0.6 alpha:1.0];
titleLabel.backgroundColor = [UIColor yellowColor];
titleLabel.autoresizingMask = UIViewAutoresizingFlexibleHeight;
titleLabel.textAlignment = UITextAlignmentCenter;
[titleLabel sizeToFit];
titleLabel.frameHeight = self.navigationController.navigationBar.frameHeight;
self.navigationItem.titleView = titleLabel;
Try this.It will help you.Thanks :)
This is the simplest solution, use the sizeToFit method before adding it to the titleView:
UILabel *titleLabel = [[UILabel alloc] init];
titleLabel.text = #"My Title";
titleLabel.font = [UIFont boldSystemFontOfSize:17.0f];
titleLabel.textColor = [UIColor whiteColor];
[titleLabel sizeToFit];
self.navigationItem.titleView = titleLabel;
Don't use NavigationItem to add left and right bar button, instead use addsubview method to add custom buttons for navigation bar.
Use a tool bar to add multiple buttons to ur navigation bar.
// create a toolbar to have two buttons in the right
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 133, 44.01)];
// create the array to hold the buttons, which then gets added to the toolbar
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];
// create a standard "add" button
UIBarButtonItem* bi = [[UIBarButtonItem alloc]`enter code here`
initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:NULL];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// create a spacer
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[buttons addObject:bi];
[bi release];
// create a standard "refresh" button
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refresh:)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// stick the buttons in the toolbar
[tools setItems:buttons animated:NO];
[buttons release];
// and put the toolbar in the nav bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
you just use this code its work fine try it
UILabel *titleLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 5, 190, 30)];
titleLabel.textColor = [UIColor whiteColor];
titleLabel.textAlignment = UITextAlignmentCenter;
titleLabel.text =#"My Wish List";
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.font = [UIFont fontWithName:#"Copperplate" size:16.0];
titleLabel.minimumFontSize = 10;
titleLabel.autoresizingMask=UIViewAutoresizingFlexibleWidth;
self.navigationItem.titleView = titleLabel;
[titleLabel release];
i use this code in my project also.......
:-)
I want to insert one button and one label in my NavigationBar in iOS.
I have tried with UISegmentedControl and it works completely fine with one control!
Now the problem is I want to add multiple controls as i have said before How can I?
Look at my code
UIView *v;
[v insertSubview:listingsLabel atIndex:0];
[v insertSubview:shareBtn atIndex:1];
[v setFrame:[self.navigationController.toolbar bounds]];
self.navigationItem.titleView = v;
v.frame = CGRectMake(0, 0, 200, 29);
and it gives me error of EXC_BAD_ACCESS
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 44.01)];
// create the array to hold the buttons, which then gets added to the toolbar
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];
// create a standard "add" button
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray array]];
[segmentedControl insertSegmentWithTitle:#"All" atIndex:0 animated:NO];
[segmentedControl insertSegmentWithTitle:#"Related" atIndex:1 animated:NO];
segmentedControl.selectedSegmentIndex = 0;
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
[segmentedControl addTarget:self action:#selector(segmentedAction:) forControlEvents:UIControlEventValueChanged];
// create a standard "add" button
UIBarButtonItem* bi = [[UIBarButtonItem alloc] initWithCustomView: segmentedControl];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// create a spacer
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[buttons addObject:bi];
[bi release];
// create a standard "refresh" button
bi = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemSave target:self action:#selector(save:)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
[bi release];
// stick the buttons in the toolbar
[tools setItems:buttons animated:NO];
[buttons release];
// and put the toolbar in the nav bar
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
Because you don't init the UIView the right way, it crashes because the iPhone doesn't know what to do with
[v insertSubview:listingsLabel atIndex:0];
This is because v isn't an object yet. So change
UIView *v;
to
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 29)];
And release it here again (if not using arc)
self.navigationItem.titleView = v;
[v release];
The navigation bar on iPhone only supports only a left and right bar button item, and a title view. Only the (larger) navigation bar on iPad allows an arbitrary number of buttons.
If you're using a navigation bar without a navigation controller, I suppose you could just plop whatever you want onto it as subviews.
UIButton *btnBack = [[UIButton alloc]initWithFrame:CGRectMake(5,5,60,32)];
[btnBack setBackgroundImage:[UIImage imageNamed:#"back_btn.png"] forState:UIControlStateNormal];
btnBack.backgroundColor = [UIColor clearColor];
[btnBack addTarget:self action:#selector(eventBack:) forControlEvents:UIControlEventTouchUpInside];
UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(12, 2, 60,25)];
[lbl setBackgroundColor:[UIColor clearColor]];
lbl.font = [UIFont fontWithName:#"Helvetica" size:12];
lbl.font = [UIFont boldSystemFontOfSize:12];
lbl.textColor = [UIColor whiteColor];
lbl.text =#" Back";
[btnBack addSubview:lbl];
[lbl release];
UIBarButtonItem *backBarBtn = [[UIBarButtonItem alloc] initWithCustomView:btnBack];
self.navigationItem.leftBarButtonItem = backBarBtn;
[btnBack release];
[backBarBtn release];
UILabel *lblTitle = [[UILabel alloc] initWithFrame:CGRectMake(110, 0, 170, 40)];
lblTitle.text = #"ABC";
lblTitle.backgroundColor = [UIColor clearColor];
lblTitle.textColor = [UIColor whiteColor];
lblTitle.textAlignment = UITextAlignmentCenter;
lblTitle.font = [UIFont fontWithName:#"Helvetica" size:17];
lblTitle.font = [UIFont boldSystemFontOfSize:17];
self.navigationItem.titleView = lblTitle;
[lblTitle release];
i got the following code:
- (id)init {
if (self = [super init]) {
self.title = #"please wait";
UIBarButtonItem *favorite = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"star.png"] style:UIBarButtonItemStylePlain target:self action:#selector(buttonFavoriteClicked:)];
self.navigationItem.rightBarButtonItem = favorite;
}
return self;
}
but my button looks still like a Button with UIBarButtonItemStyleBordered
is there a way to set a button with plain style at this position?
Create a UIButton in interface builder, make it look like exactly what you want. Create an outlet for in in your .h:
IBOutlet UIButton * _myButton;
Then set it as your right bar button item using a custom view, which will eliminate the border:
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:_myButton];
This works because UIButton is a subclass of UIView.
Try this instead:
- (id)init {
if (self = [super init]) {
self.title = #"please wait";
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 25, 25)];
[button setImage:[UIImage imageNamed:#"star.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonFavoriteClicked) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *favorite = [[UIBarButtonItem alloc] initWithCustomView:button];
[button release];
self.navigationItem.rightBarButtonItem = favorite;
}
return self;
}
Hope it helps.
Or do this in code without IB:
// add setting button to nav bar
UIImage* settingsGearImg = [UIImage imageNamed:#"settings_gear.png"];
CGRect frameimg = CGRectMake(0, 0, settingsGearImg.size.width, settingsGearImg.size.height);
UIButton *settingsButton = [[UIButton alloc] initWithFrame:frameimg];
[settingsButton setBackgroundImage:settingsGearImg forState:UIControlStateNormal];
[settingsButton addTarget:self action:#selector(settingsButtonAction) forControlEvents:UIControlEventTouchUpInside];
[settingsButton setShowsTouchWhenHighlighted:YES];
UIBarButtonItem *settingButtonItem =[[UIBarButtonItem alloc] initWithCustomView:settingsButton];
self.navigationItem.leftBarButtonItem = settingButtonItem;
Results in:
When using this icon image (it's white on a white background so isn't visible here - link is: http://i.stack.imgur.com/lk5SB.png):
It's weird but it works. Say "No" to images/outlets! You shouldn't even set the UIBarButtonItemStylePlain property. The trick is to place button into UIToolBar with some special attributes:
UINavigationItem *item = [[UINavigationItem alloc] initWithTitle:#"Cool plain bar"];
UIToolbar *tools = [[UIToolbar alloc]
initWithFrame:CGRectMake(0.0f, 0.0f, 44.0f, 44.01f)];
tools.clipsToBounds = NO;
tools.barStyle = -1; // clear background
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:1];
UIBarButtonItem *bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refreshTableView)];
[buttons addObject:bi];
[tools setItems:buttons animated:NO];
UIBarButtonItem *rightButtons = [[UIBarButtonItem alloc] initWithCustomView:tools];
item.rightBarButtonItem = rightButtons;
item.hidesBackButton = YES;
[myCoolNavigationBar pushNavigationItem:item animated:NO];
Although Frank is right, this code should be in viewDidLoad, the issue here is what BarButtons look like. If you want it to look different, you need to use a different type of UIView. You can add a UIButton to a UIToolbar just fine.
-(void)viewDidLoad {
[super viewDidLoad];
self.title = #"please wait";
self.navigationItem.rightBarButtonItem = [[[UIButton alloc] init] autorelease];
}
Edit:
Sorry, you wanted a plain UIBarButtonItem. I don't believe you can do this with a UINavigationBar. You could try adding a UserInteractionEnabled UILabel as the rightBarButtonItem, I'm not sure if it will work or not.
Seems this isn't currently possible.
sbwoodside has a solution.
Why not try UI7Kit? Works well for me, easy to use.
UIImage *img = [UIImage imageNamed:#"white_star.png"];
CGSize itemSize = CGSizeMake(20, 20);
UIGraphicsBeginImageContext(itemSize);
CGRect imageRect = CGRectMake(0.0, 0.0, itemSize.width, itemSize.height);
[img drawInRect:imageRect];
img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
UIBarButtonItem *barButton = [[UIBarButtonItem alloc ] initWithImage:img style:UIBarButtonSystemItemAdd target:self action:#selector(favoriteButtonClicked)];
barButton.style = UIBarButtonItemStyleBordered;
Try this,
UIBarButtonItem *barBtn = [[UIBarButtonItem alloc]initWithImage:[UIImage imageNamed:#"more.png"] style:UIBarButtonItemStylePlain target:self action:#selector(didPressButton)];
