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 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 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.......
:-)
This blue "OK" button is common in a UIWebview when you click in a webform at iPhone.
Are there a easy way to recreate it in code? Or I will have to create it in a hard way?
The most close code was:
UISegmentedControl *buttonOK = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObject:#"OK"]];
[buttonOK setSegmentedControlStyle:UISegmentedControlStyleBar];
[buttonOK setTintColor:[UIColor colorWithRed:0.25f green:0.51f blue:0.95f alpha:1.0f]];
[buttonOK setFrame:CGRectMake(276, 8, 38, 30)];
But isn't the same...
The button in the web view uses a translucent UIToolbar with a done button style:
UISegmentedControl* segmentedControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"Previous", #"Next", nil]];
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.tintColor = [UIColor blackColor];
segmentedControl.momentary = YES;
UIBarButtonItem* segmentedControlItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
UIBarButtonItem* item = [[UIBarButtonItem alloc] initWithTitle:#"OK" style:UIBarButtonItemStyleDone target:self action:#selector(done:)];
UIBarButtonItem* flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:NULL];
UIToolbar* toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
toolbar.barStyle = UIBarStyleBlack;
toolbar.translucent = YES;
toolbar.items = [NSArray arrayWithObjects:segmentedControlItem, flexSpace, item, nil];
[self.view addSubview:toolbar];
I want add a UIToolbar to the keyboard for my UITextField. Here is the code I'm using:
UIToolbar *toolbar = [[UIToolbar alloc] init];
toolbar.tintColor = [UIColor blackColor];
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(someFunction)];
doneButton.tintColor = [UIColor blackColor];
UISegmentedControl *directionControl = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:#"Back", #"Next", nil]];
directionControl.tintColor = [UIColor blackColor];
directionControl.segmentedControlStyle = UISegmentedControlStyleBar;
[directionControl addTarget:self action:#selector(directionControlPressed) forControlEvents:UIControlEventValueChanged];
UIBarButtonItem *segItem = [[UIBarButtonItem alloc] initWithCustomView:directionControl];
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[toolbar setItems:[NSArray arrayWithObjects:segItem, flexibleSpace, doneButton, nil]];
// Assign the toolbar to the text fields
self.textField.inputAccessoryView = toolbar;
However, here is what it looks like when I run the code:
The toolbar doesn't seem to be high enough; also I notice that the tint colour of the toolbar hasn't been acknowledged.
Please can someone help me out?
Think you need to set the toolbar's frame, at least its size. As I recall, I used [toolbar sizeToFit] to get the height and had to use the window width to get the width.
I created a nav bar and a label programmatically in my view controller. Now I want to add a "done" button but cant seem to find a way without using IB....is there any way to do that?
Here is my view controller's viewDidLoad:
//Adding navBar programmatically
CGFloat width = self.view.frame.size.width;
UINavigationBar *navBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0,0,width,52)];
navBar.autoresizingMask = UIViewAutoresizingFlexibleWidth;
[self.view addSubview:navBar];
//Adding label to navBar programmatically
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10,2,width-20,14)];
label.autoresizingMask = UIViewAutoresizingFlexibleWidth;
label.text = #"TITLE";
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont systemFontOfSize:22];
label.shadowOffset = CGSizeMake(1,1);
label.textColor = [UIColor whiteColor];
label.textAlignment = UITextAlignmentCenter;
[navBar addSubview:label];
//Adding back button to navBar programmatically
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStylePlain target:self action:#selector(dismissView:)];
self.navigationItem.leftBarButtonItem = rightButton;
Last part obviously doesnt work...
Thanks for any help!
Why are you not using a UIToolBar instead?
To add buttons to a UINavigationBar, you need to create a UINavigationItem. If you're using UINavigationBar as part of UINavigationController (as is the common case), this is done automatically, as a standalone view, you have to do this yourself.
UINavigationItem *item = [[[UINavigationItem alloc] initWithTitle:#""] autorelease];
item.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleDone target:self action:#selector(dismissView:)] autorelease];
[navBar setItems:[NSArray arrayWithObject:item] animated:NO];
The navigationItem is only used when you push a viewcontroller in a navigationcontroller
in your case you need to use
-pushNavigationItem:animated:
on the UINavigationBar
