I have my navigation bar title as a label that I am trying to resize the font. I have the right bar button set up as an array of two buttons. Instead of resizing the title just knocks off one of the right buttons.
here is my code
- (void)setTitle:(NSString *)title
{
[super setTitle:title];
UILabel *titleView = (UILabel *)self.navigationItem.titleView;
if (!titleView) {
titleView = [[UILabel alloc] initWithFrame:CGRectZero];
titleView.backgroundColor = [UIColor clearColor];
titleView.font = [UIFont boldSystemFontOfSize:18.0];
titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
titleView.textColor = [UIColor greenColor]; // Change to desired color
[titleView sizeToFit];
titleView.minimumScaleFactor = .33f;
CGRect frame = self.navigationItem.titleView.frame;
frame.origin .x = 10;
self.navigationItem.titleView = titleView;
self.navigationItem.titleView.frame = frame;
self.navigationItem.titleView = titleView;
}
titleView.text = title;
[titleView sizeToFit];
titleView.adjustsFontSizeToFitWidth = TRUE;
}
as you can see I have set the max font size to 18 and the min to 6 being .33 of the max size. I have also tried to align it to the left but that didn't work. The following code set up an array of two button on the right side.
buttonimage = [UIImage imageNamed:#"share icon1 Camera.png"];
UIBarButtonItem *saveButton =[[UIBarButtonItem alloc]
initWithImage:buttonimage
style:UIBarButtonItemStyleBordered
target:self
action:#selector(shareByActivity:)];
buttonimage2 = [UIImage imageNamed:#"mail icon sm Sound.png"];
UIBarButtonItem *soundButton =[[UIBarButtonItem alloc]
initWithImage:buttonimage2
style:UIBarButtonItemStyleBordered
target:self
action:#selector(shareByActivity2:)];
self.navigationItem.rightBarButtonItem = saveButton;
self.navigationItem.rightBarButtonItems = [NSArray arrayWithObjects:soundButton,saveButton, nil];
how can I get the title to resize and not cover the second button of the array"
Can I set an if statement that if the title string is more that so many characters then the font size is something.

I have the code likes, in the title bar I am having 3 buttons, left search button, right camera button and option button, in between I am having title.
What I want to do is, I want to display the title centered between the search button and Camera button, can anyone help me how to do this.
//Left Button
UIBarButtonItem *leftSearch = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"btn_search"] style:UIBarButtonItemStyleBordered target:self action:#selector(gotoSearch)];
leftSearch.imageInsets = UIEdgeInsetsMake(0, -5.0f, 0, 0);
[leftSearch setTintColor:[UIColor whiteColor]];
/////////
//Right Button -- First Camera
UIBarButtonItem *rightCamera = [[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:#"icon_camera"]
style:UIBarButtonItemStyleBordered
target:self
action:#selector(gotoPhotoGallery)];
[rightCamera setTintColor:[UIColor whiteColor]];
rightCamera.imageInsets = UIEdgeInsetsMake(0, 0, 0, -59.0f);
///////////////////
//Right second Button -- for options menu
UIBarButtonItem *rightMenu = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:#"header_option"] style:UIBarButtonItemStyleBordered target:self action:#selector(gotoPhotoGallery)];
[rightMenu setTintColor:[UIColor whiteColor]];
rightMenu.imageInsets = UIEdgeInsetsMake(0, 0, 0, 5.0f);
///////////////////
NSArray *buttons = #[rightMenu, rightCamera];
self.navigationItem.rightBarButtonItems = buttons;
[[self navigationItem] setLeftBarButtonItem:leftSearch];
//Title Label
UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.backgroundColor = [UIColor clearColor];
label.font = [UIFont fontWithName:#"Museo Sans" size:20];
label.textAlignment = UITextAlignmentCenter;
label.textColor = [UIColor whiteColor];
label.text = LoginUserName;
self.navigationItem.titleView = label;
[label sizeToFit];
Create your title label with the same width and height as the navigation bar. For example
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0, self.view.frame.size.width,44)];
titleLabel.textAlignment = NSTextAlignmentCenter;
titleLabel.text = LoginUserName;
titleLabel.textColor = [UIColor whiteColor];
[self.navigationController.navigationBar addSubview:titleLabel];
This will put your text in the middle.
I'm trying to figure out how can I achieve something like this:
This is a toolbar and I'd like to keep the button title text without having to create the whole image with icon AND text. How can I add the icon to the left of the UIBarButtonItem while keeping the text set with:
UIBarButtonItem *customBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:#"Button" style:UIBarButtonItemStyleBordered target:nil action:nil];
EDIT
This is what I achieved with the following code:
UIButton *customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setImage:[UIImage imageNamed:#"Test"] forState:UIControlStateNormal];
[customButton setTitle:#"Button" forState:UIControlStateNormal];
customButton.titleEdgeInsets = UIEdgeInsetsMake(0, 5, 0, 0);
[customButton sizeToFit];
UIBarButtonItem *customBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:customButton];
Two issues here: the first is the size of the UIButton and the second is that, as you can see from the gif, the button doesn't animate properly when I tap inside the button and when I release the tap. Any ideas?
You can embed a UIButton as a custom view inside your UIBarButtonItem. You can create your UIButton however you want, including with an image and text, using -setImage:forState: and -setTitle:forState:.
UIButton* customButton = [UIButton buttonWithType:UIButtonTypeCustom];
[customButton setImage:[UIImage imageNamed:#"image"] forState:UIControlStateNormal];
[customButton setTitle:#"Button" forState:UIControlStateNormal];
[customButton sizeToFit];
UIBarButtonItem* customBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:customButton];
self.navigationItem.leftBarButtonItem = customBarButtonItem; // or self.navigationItem.rightBarButtonItem
Note that when doing this, you'll need to attach your IBAction methods to customButton, not to customBarButtonItem.
For more info, see the documentation for initWithCustomView:.
You can also do all of this in interface builder just by dragging a UIButton to the left bar button/right bar button slot on a navigation bar.
I was not satisfied with all solutions found on stack overflow becauseI like how UIBarButtonItenm convert images so they are displayed correctly and they can be changed with tint colour. So i discovered this solution that I can use nicely with not much code... End effect is similar to toolbar in facebook and other current apps...
When you change tint colour of view contained in UIBArButtonItem colours of image and title change accordingly, really cool , I do not have to create special images at all.
This code is called from each button like that Competition Button, and also Button is set as referencing outlet...
- (void)selectButton:(UIButton *)sender {
_competitionButton.superview.tintColor = [UIColor lightGrayColor];
_usersButton.superview.tintColor = [UIColor lightGrayColor];
_managementButton.superview.tintColor = [UIColor lightGrayColor];
sender.superview.tintColor = [UIColor whiteColor];
}
- (IBAction)onCompetitionButtonClick:(UIButton *)sender {
[self selectButton:sender];
[_scrollView scrollToPage:0 of:3];
}
In Button like that titled Competition there is only title and in bar button item there is image... This is how I have setup it and it works , maybe there are also other possibilities..
So I managed to do my solution programatically... Some users where complaining it does not work ... So how to create UTToolbar with image and item so that you can change color of button by tint and it magically alters image as well as title label ? My UI editor solution works for sure...
In this code can clarify things more and you can do it programatically either...
- (void)loadToolbar {
NSMutableArray *items = NSMutableArray.new;
[items add:[UIBarButtonItem createWithItem:UIBarButtonSystemItemFlexibleSpace :nil :nil]];
for (uint pageIndex = 0; pageIndex < _controllers.count; ++pageIndex) {
UIView *itemView = [UIView.alloc initWithFrame:CGRectMake(0, 0, 100, 44)];
itemView.backgroundColor = [UIColor clearColor];
itemView.tintColor = [UIColor orangeColor];
[itemView addSubview:[self createToolbarForItemView:pageIndex]];
[itemView addSubview:[self createButtonForItemView:pageIndex]];
UIBarButtonItem *item = [UIBarButtonItem.alloc initWithCustomView:itemView];
item.style = UIBarButtonItemStylePlain;
[items add:item];
[items add:[UIBarButtonItem createWithItem:UIBarButtonSystemItemFlexibleSpace :nil :nil]];
}
[_toolbar setItems:items];
}
- (UIButton *)createButtonForItemView:(uint)pageIndex {
UIButton *itemButton = [UIButton buttonWithType:UIButtonTypeSystem];
itemButton.frame = CGRectMake(0, 0, 100, 44);
itemButton.titleLabel.font = [UIFont systemFontOfSize:11];
itemButton.contentEdgeInsets = UIEdgeInsetsMake(30, 0, 0, 0);
itemButton.text = [_controllers[pageIndex] tabTitle];
itemButton.touchUp = ^(UIButton *sender) {
for (UIButton *button in _buttons) button.superview.tintColor = UI.toolBarInactiveButtonTextColor;
sender.superview.tintColor = UI.toolBarActiveButtonTextColor;
[self showPage:pageIndex];
};
[_buttons add:itemButton];
return itemButton;
}
- (UIToolbar *)createToolbarForItemView:(uint)pageIndex {
UIToolbar *itemToolbar = [UIToolbar.alloc initWithFrame:CGRectMake(0, 0, 100, 44)];
itemToolbar.tintColor = nil;
itemToolbar.barStyle = _toolbar.barStyle;
itemToolbar.translucent = _toolbar.translucent;
UIBarButtonItem *imageItem = [_controllers[pageIndex] tabImageItem];
imageItem.style = UIBarButtonItemStylePlain;
imageItem.tintColor = nil;
imageItem.imageInsets = UIEdgeInsetsMake(-10, 0, 0, 0);
itemToolbar.items = #[
[UIBarButtonItem createWithItem:UIBarButtonSystemItemFlexibleSpace :nil :nil],
imageItem,
[UIBarButtonItem createWithItem:UIBarButtonSystemItemFlexibleSpace :nil :nil]
];
return itemToolbar;
}
I solved this problem as follows:
[Button **setTitleColor**:[UIColor colorWithRed:129/255.0f green:124/255.0f blue:110/255.0f alpha:1.0f] forState:**UIControlStateHighlighted**];
after going through the questions related to UINavigationController item i came to post my exact problem ..
firstly i am not add a UINavigationController in MainWindow.xib i created and adding UINavigationController in AppDelegate file
after that in a UIViewController (not in rootViewController) class I have to add a rightbarbutton of Done type I am
adding it in a searchbarDelegate Method showing as bold:-
- (void) searchBarTextDidBeginEditing:(UISearchBar *)theSearchBar {
//This method is called again when the user clicks back from teh detail view.
//So the overlay is displayed on the results, which is something we do not want to happen.
if(exhibDataObj.searching)
return;
//Add the overlay view.
if(ovController == nil)
ovController = [[OverlayViewController alloc] initWithNibName:#"OverlayView" bundle:[NSBundle mainBundle]];
CGFloat yaxis = self.navigationController.navigationBar.frame.size.height;
CGFloat width = self.view.frame.size.width;
CGFloat height = self.view.frame.size.height;
//Parameters x = origion on x-axis, y = origon on y-axis.
CGRect frame = CGRectMake(0, yaxis, width, height);
ovController.view.frame = frame;
ovController.view.backgroundColor = [UIColor grayColor];
ovController.view.alpha = 0.5;
ovController.rvController = self;
[self.theTableView insertSubview:ovController.view aboveSubview:self.parentViewController.view];
exhibDataObj.searching = true;
letUserSelectRow = NO;
self.theTableView.scrollEnabled = NO;
//Add the done button.
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self action:#selector(doneSearching_Clicked:)];
}
but this never works .
Any help will be more appreciable.
I've tested your code real quick and it seems to be working fine for me, however, I've had the same problem once back then it turned out I was setting the rightBarButtonItem to nil in my viewDidLoad method after setting it to a button. you should make sure your not making the same mistake somehow.
However if that does not work for you you can always try setting a custom button to it:
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(0, 5, 30, 30)];
button.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:#"done.png"]];
[button addTarget:self action:#selector(doneButtonClicked) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *customItem = [[UIBarButtonItem alloc] initWithCustomView:button];
self.navigationController.visibleViewController.navigationItem.rightBarButtonItem = customItem;
