in my app i have a uinavigationbar with 3 buttons, but the code i used for ios5 does not seem to be good for ios6 anymore.
You can see a wrong-colored rect underneath my custum-view with two buttons on the right side.
heres the code i used, i found it somewhere on stackoverflow:
UIToolbar *tools = [[[UIToolbar alloc]
initWithFrame:CGRectMake(0.0f, 0.0f, 110.0f, 44.01f)] autorelease]; // 44.01 shifts it up 1px for some reason
tools.clearsContextBeforeDrawing = NO;
tools.clipsToBounds = NO;
tools.translucent = self.headerbar.translucent;
tools.barStyle = self.headerbar.barStyle;
tools.backgroundColor = self.headerbar.backgroundColor;
tools.tintColor = self.headerbar.tintColor;
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3];
// Create a standard refresh button.
UIBarButtonItem *bi = [[UIBarButtonItem alloc] initWithTitle:#"heute" style:UIBarButtonItemStylePlain target:self action:#selector(showThisWeek)];
bi.style = UIBarButtonItemStyleBordered;
bi.width = 0;
[buttons addObject:bi];
//[bi release];
// Create a spacer.
bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:#selector(showThisWeek)];
[buttons addObject:bi];
//[bi release];
// Add profile button.
bi = [[UIBarButtonItem alloc] initWithTitle:#"vor" style:UIBarButtonItemStylePlain target:self action:#selector(showNext)];
bi.style = UIBarButtonItemStyleBordered;
[buttons addObject:bi];
//[bi release];
// Add buttons to toolbar and toolbar to nav bar.
[tools setItems:buttons animated:NO];
[buttons release];
UIBarButtonItem *twoButtons = [[UIBarButtonItem alloc] initWithCustomView:tools];
//[tools release];
header.rightBarButtonItem = twoButtons;
[header.leftBarButtonItem setAction:#selector(showPrevious)];
can someone hint me to a more elegant solution that works fine on both ios5 and ios6?
cheers

Did you try leftBarButtonItems and rightBarButtonItems? You can add array of buttons in left and right side nav bar using this.
If you use this, there will be no need for UIToolbar and their subviews.
Have you tried bar.style = -1?

So I'm tasked with adding buttons to a UIToolBar and setting the inputAccessoryView of a textView to this UIToolBar.
so I did the basics:
UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithTitle:#"title1" style:UIBarButtonItemStylePlain target:self action:selector];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithTitle:#"longer title2" style:UIBarButtonItemStylePlain target:self action:selector];
UIBarButtonItem *item3 = [[UIBarButtonItem alloc] initWithTitle:#"title 3 is a lot longer" style:UIBarButtonItemStylePlain target:self action:selector];
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *divider1 = [self barButtonDivider];
UIBarButtonItem *divider2 = [self barButtonDivider];
UIToolBar *toolBar = [UIToolBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
[toolBar setItems:#[spacer,item1,spacer,divider1,spacer,item2,spacer,divider2,spacer,item3,spacer];
self.textView.inputAccessoryView = toolbar;
So there are more approaches to this.
1) I could subclass a UIToolBar
2) I could subclass a UIView and set a view to be the size I need (width of the superView and height 44), but I'd need to do all of this in Auto-Layout which I tried and could not get right.
Is there a way I can use the above method with a standard ToolBar and get the right spacing where all the buttons no matter how many I use are equal widths?
ETA:, tried the below solution and didn't work:
- (UIBarButtonItem *)spacer {
return [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
}
[toolBar setItems:#[[self spacer], item1, [self spacer], divider1, [self spacer], item2, [self spacer], divider2, [self spacer], item3, [self spacer]];
Resolved with this solution but I don't like it:
button.width = 150;
the buttons would remain equal in portrait or landscape so I guess this is a working solution what do you think?
I'm not sure, but issue might be in reusing spacer. Try to create new UIBarButtonSystemItemFlexibleSpace every time you need flexible space.
I have created custom navigation controller,
I want to be added, a date at the left, a back button on the right and the title next to back button.
I tried to add one label, but it does not work. Please show me a way
UINavigationBar *naviBarObj = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 1024, 66)];
UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(20,8,280,30)];
navLabel.text = #"My Text";
[self.navigationController.navigationBar addSubview:navLabel];
[self.view addSubview:naviBarObj];
UINavigationBar *naviBarObj = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, 1024, 66)];
UILabel *navLabel = [[UILabel alloc] initWithFrame:CGRectMake(200,8,200,30)];
navLabel.text = #"My Text";
navLabel.textColor = [UIColor redColor];
[naviBarObj addSubview:navLabel];
[navLabel setBackgroundColor:[UIColor clearColor]];
[self.view addSubview:naviBarObj];
try this it will work .It works for me :)
add custom view in UIToolbar
UIToolbar *tools = [[UIToolbar alloc]
initWithFrame:CGRectMake(0.0f, 0.0f,190.0f, 44.01f)];
tools.barStyle = -1; // clear background
NSMutableArray *buttons = [[NSMutableArray alloc] init];
UIBarButtonItem *bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
bi.width =10.0f;
[buttons addObject:bi];
[buttons addObject:add your view];
bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
bi.width =10.0f;
[buttons addObject:bi];
[buttons addObject:add your view];
[tools setItems:buttons animated:NO];
UIBarButtonItem *buttons_ = [[UIBarButtonItem alloc] initWithCustomView:tools];
self.navigationItem.rightBarButtonItem = buttons_; //same to leftBarButtonItem
You can also achieve this from Interface Builder
1. First add a UIView which will look like following
2. Then add a UILabel inside the UIView which will look like following
3. In the Center It will look like following
Now add necessary constraint to meet your requirement.
You need to add navigation item to the navigation bar. One per each navigation level. So you should have at least one of them.
** update **
UINavigationItem * myNavItem = [[UINavigationItem alloc] initWithTitle:#"Some title"];
/*
* add buttons and labels
*/
[self.navigationController.navigationBar pushNavigationItem:myNavItem animated:NO];
You need to change the titleView of the topItem. Like this:
naviBarObj.topItem.titleView = navLabel;
** update: Complete code (tested and working) **
UINavigationBar *naviBar = [[UINavigationBar alloc] initWithFrame: CGRectMake(.0, .0, 320.0, 44.0)];
UINavigationItem *navItem = [[UINavigationItem alloc] init];
navItem.titleView = titleLbl;
[naviBar pushNavigationItem: navItem animated: NO];
[navItem release]; // you don't need this for ARC
[self.view addSubview: naviBar];
[naviBar release]; // you don't need this for ARC
When an item from a UITableView is selected, a detail view is loaded which has a banner bar at the top with a back button on it to navigate back to the table.
How do I add other buttons to that banner bar?
As Andrew said, you can add custom views to the navigation bar. For example, if you are looking to add multiple buttons to the right side of the navigation bar, you can do something like this:
// right side of nav bar
UIToolbar *toolbar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 106, 44)];
NSMutableArray *buttons = [[NSMutableArray alloc] initWithCapacity:3];
UIBarButtonItem *deleteButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemTrash
target:self
action:#selector(deleteAction:)];
deleteButton.style = UIBarButtonItemStyleBordered;
[buttons addObject:deleteButton];
[deleteButton release];
UIBarButtonItem *spacer = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil
action:nil];
[buttons addObject:spacer];
[spacer release];
UIBarButtonItem *cancelButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:self
action:#selector(cancelAction:)];
cancelButton.style = UIBarButtonItemStylePlain;
[buttons addObject:cancelButton];
[cancelButton release];
[toolbar setItems:buttons animated:NO];
toolbar.barStyle = -1;
[buttons release];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:toolbar];
[toolbar release];
Make sure to adjust the width (106 above) if you need more or wider buttons, and then provide methods for the selectors (deleteAction: and cancelAction: above).
From your description, it sounds like you have a UINavigationController correctly set up. That "banner bar" you are describing is properly called a navigation bar.
From within the detail view, you can use:
UIBarButtonItem* button = [[[UIBarButtonItem alloc] initWithTitle:"HiMom" style:UIBarButtonItemStylePlain target:self action:#selector(onHiMom:)] autorelease];
self.navigationItem.rightBarButtonItem = button;
You can also add custom views (instead of a button) plus a few other settings. I suggest poking around the documentation for UINavigationItem, UINavigationBar, and UIBarButtonItem for ideas.
I need to dynamically add a UIViewController that contains a nav bar with multiple buttons. When one of the buttons is pressed i need to swap the displayed view for another, while keeping the nav bar.
CGRect appFrame = [[UIScreen mainScreen] applicationFrame];
ViewControllerOne* viewOne = [[ViewControllerOne alloc] init];
[viewOne.view setFrame:appFrame];
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 320, 44.01)];
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:3];
UIBarButtonItem* bi = [[UIBarButtonItem alloc] initWithTitle:#"Back" style:UIBarButtonItemStyleBordered target:self action:#selector(back:)];
[buttons addObject:bi];
[bi release];
bi = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
[buttons addObject:bi];
[bi release];
bi = [[UIBarButtonItem alloc] initWithTitle:#"Two" style:UIBarButtonItemStyleBordered target:self action:#selector(showTwo:)];
[buttons addObject:bi];
[bi release];
[tools setItems:buttons animated:NO];
[buttons release];
viewOne.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
m_navViewController = [[UINavigationController alloc] initWithRootViewController:viewOne];
[m_navViewController.view setFrame: appFrame ];
[self addSubview: m_navViewController.view];
Now when someone presses the Two button i would like to remove viewOne and add a ViewControllerTwo object
- (void) showTwo:(id)sender{
ViewControllerTwo* viewTwo = [[ViewControllerOne alloc] init];
[viewOne.view setFrame:[[UIScreen mainScreen] applicationFrame]];
// remove viewOne from m_navViewController and add viewTwo
}
In other words i want to show different views by pressing one of items in the nav bar but keep the same nav bar for all views.
Please note the nav bar will actually hold five buttons. I have simplified it for explanation purposes.
Thanks in advance.
You could use the nav controller template; add the buttons to the nav bar in IB (or in the code as you do above), then when one of them is tapped you push on the corresponding view controller.
Accept my early apologies as totally new to this so my terminology may not be accurate, hope you can understand what it is that i'm asking.
I am having issues getting a UIBarButtonSystemItem to take me back to a different view when pushed. I have defined a UIToolBar with a UIBarButtonSystemItem on it which compiles and works perfectly. However, when the button is pushed the app crashes.
This is the code i have used to define the UIToolBar and UIButton:
//create toolbar using new
toolbar = [UIToolbar new];
toolbar.barStyle = UIBarStyleBlackTranslucent;
[toolbar sizeToFit];
toolbar.frame = CGRectMake(0, 410, 320, 50);
//Add buttons
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAction
target:self
action:#selector(pressButton1:)];
I have then added flexitem to this and added the button to the array using the following code:
//Use this to put space in between your toolbox buttons
UIBarButtonItem *flexItem = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace
target:nil
action:nil];
//Add buttons to the array
NSArray *items = [NSArray arrayWithObjects: systemItem1, flexItem, nil];
This is where I fall down and I have attempted to get the button to take me to a previous view when pushed by using the following code:
-(void)pressButton1:(id)sender {
BMR_TDEE_CalculatorViewController *controller1 = [[BMR_TDEE_CalculatorViewController alloc] initWithNibName:#"BMR_TDEE_ViewController" bundle:nil];
controller1.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController:controller1 animated:YES];
[controller1 release];
}
Like I said, this just crashes my simulator. It compiles without issue but Im guessing the code is fundamentally wrong as i am new to this. Any help explained dumbed down would be fantastic ;-)
Thanks All
This:
UIBarButtonItem *systemItem1 = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:self action:#selector(pressButton1:)
should be:
UIButton *button=[[UIButton alloc] init];
button.frame=CGRectMake(0, 0, 65, 32);
[button addTarget:self action:#selector(pressButton1:) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
For the (void)pressbutton code it should now be:
-(IBAction)pressButton1:(id)sender {
BMR_TDEE_CalculatorViewController *controller = [[BMR_TDEE_CalculatorViewController alloc] initWithNibName:#"BMR_TDEE_CalculatorViewController" bundle:nil];
[self.navigationController presentModalViewController:controller animated:TRUE];
}
