I only add UIBarbuttonitem at left or right. Now i want to add UIbarbuttonitem at centre on uinavigationbar. How can i do that? Thanks much
Try this:
UIButton *titleButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[titleButton setFrame:CGRectMake(0, 0, 170, 35)];
self.navigationItem.titleView = [[UIBarButtonItem alloc] initWithCustomView:titleButton];
You could add another UIBarButtonItem as a 'spacer' like this:
UIBarButtonItem *barButton = [[UIBarButtonItem alloc] initWithTitle:#"Button" style:UIBarButtonItemStyleBordered target:self action:#selector(buttonTapped)];
UIBarButtonItem *spacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
spacer.width = 125.0f;
[self.navigationItem setRightBarButtonItems:[NSArray arrayWithObjects:spacer, barButton, nil]];

I am using the following code to achieve a navigation bar in my app. (my app was crashing when I used a push segue so I need a modal segue meaning the nav bar is hidden after the modal segue is called)
UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
//do something like background color, title, etc you self
[self.view addSubview:navbar];
Does any one know any methods I can use with the above code to achieve back button functionality in the nav bar??
Use below code to add back button on left side of navigation bar.Add UIBarButtonItem on Navigation bar.
UIBarButtonItem *backButton = [[UIBarButtonItem alloc]
initWithTitle:#"Back"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(backBtnClicked:)];
self.navigationItem.leftBarButtonItem = backButton;
Use below code to add back button on left side
UINavigationBar *navbar = [[UINavigationBar alloc]initWithFrame:CGRectMake(0, 0, 320, 50)];
//do something like background color, title, etc you self
[self.view addSubview:navbar];
UINavigationItem *item = [[UINavigationItem alloc]
init];
navbar.items= #[item];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc]
initWithTitle:#"Back"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(backBtnClicked:)];
item.leftBarButtonItem = backButton;
BackButton is better than LeftButton I think:
UIBarButtonItem *backBtn = [[UIBarButtonItem alloc] init];
[desVC.navigationItem setBackBarButtonItem:backBtn];
Add Back Button With Image :
UIButton *backButton = [[UIButton alloc] initWithFrame: CGRectMake(0, 0, 70.0f, 21.0f)];
UIImage *backImage = [UIImage imageNamed:#"backBtn"];
[backButton setImage:backImage forState:UIControlStateNormal];
[backButton setTitleEdgeInsets:UIEdgeInsetsMake(10.0, 10.0, 10.0, 0.0)];
[backButton setTitle:#"Back" forState:UIControlStateNormal];
[backButton addTarget:self action:#selector(backButtonPressed:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *backButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButton];
UIBarButtonItem *negativeSpacer = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
[negativeSpacer setWidth:-15];
self.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:negativeSpacer,backButtonItem,nil];
Regarding the back button, the proper way is not to create your own.
The UINavigationItem class has proper support for this:
func setHidesBackButton(_:animated:)
var leftItemsSupplementBackButton: Bool
So, if you want to add a custom button on the left side, just set leftItemsSupplementBackButton to true.
Or call
self.navigationItem.setHidesBackButton(false, animated:false)
I have four right bar button items added in a navigation bar.
UIButton *replybutton = [UIButton buttonWithType:UIButtonTypeCustom];
[replybutton setImage:[UIImage imageNamed:#"reply.png"] forState:UIControlStateNormal];
[replybutton addTarget:self action:#selector(replyAction:)forControlEvents:UIControlEventTouchUpInside];
[replybutton setFrame:CGRectMake(0, 0, 30, 28)];
UIBarButtonItem *replyBarButton = [[UIBarButtonItem alloc] initWithCustomView:replybutton];
// there are 3 more buttons like this..
self.navigationItem.rightBarButtonItems = [[NSArray alloc] initWithObjects:replyBarButton, replyAllBarButton, forwardBarButton, deleteBarButton, nil];
I want to give some extra spacing between these four bar button custom type items. I tried imageInsets,
replyBarButton.imageInsets = UIEdgeInsetsMake(0.0, 40.0, 0.0, 0.0);
but it doesn't give spacing. Could someone advise me, how can i give extra spacing between four right bar custom type button items?
You can use UIBarButtonSystemItemFlexibleSpace or UIBarButtonSystemItemFixedSpace.
Here is an example:
UIButton *button1 = [UIButton buttonWithType:UIButtonTypeCustom];
[button1 setImage:[UIImage imageNamed:#"icon.png"] forState:UIControlStateNormal];
[button1 addTarget:self action:#selector(replyAction:) forControlEvents:UIControlEventTouchUpInside];
[button1 setFrame:CGRectMake(0, 0, 30, 28)];
// other buttons are created the same way
UIBarButtonItem *item1 = [[UIBarButtonItem alloc] initWithCustomView:button1];
UIBarButtonItem *item2 = [[UIBarButtonItem alloc] initWithCustomView:button2];
UIBarButtonItem *item3 = [[UIBarButtonItem alloc] initWithCustomView:button3];
UIBarButtonItem *item4 = [[UIBarButtonItem alloc] initWithCustomView:button4];
UIBarButtonItem *space1 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *space2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *space3 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
self.navigationItem.rightBarButtonItems = #[item1, space1, item2, space2, item3, space3, item4];
In this example, you are adding flexible spaces between every item. This will automatically space your items evenly.
If you want, you can also define the space:
UIBarButtonItem *fixedSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
fixedSpace.width = 40.0 // adjust this
I am adding two button in navigation bar they are working fine but i want space between them they are both combined i want a bit space between them
UIBarButtonItem *btnAdd = [[UIBarButtonItem alloc] initWithTitle:#"Add"
style:UIBarButtonItemStylePlain
target:self
action:#selector(Add)];
UIBarButtonItem *btnEdit = [[UIBarButtonItem alloc] initWithTitle:#"Add"
style:UIBarButtonItemStylePlain
target:self
action:#selector(Add)];
UIToolbar *rightToolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
rightToolBar.backgroundColor = [UIColor clearColor];
rightToolBar.tintColor = [UIColor colorWithRed:40.0/255.0 green:48.0/255.0 blue:51.0/255.0 alpha:0.0];
NSArray *buttonsRight = [NSArray arrayWithObjects:btnEdit, btnAdd, nil];
[rightToolBar setItems:buttonsRight];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:rightToolBar];
You can add any of these two between your UIBarButtonItem
UIBarButtonItem *fixed = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil]
UIBarButtonItem *flexible = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil]
Note that to set the width of a Fixed Space UIBarButtonItem, you need to set the .width property
[fixed setWidth:455.0f];
I wish to place a UILabel on a UITabbar,how can I implement that ?
This should do the trick, assuming you're using a UINavigationController with a toolbar:
(it has a flexible space on either side to center it.
CGRect myFrame = CGRectMake(0, 0, 100, 44);
UILabel *myLabel = [[UILabel alloc] initWithFrame:myFrame];
UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:NULL];
UIBarButtonItem *labelItem = [[UIBarButtonItem alloc] initWithCustomView:myLabel];
UIBarButtonItem *spaceItem2 = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:NULL];
[self setToolbarItems:[NSArray arrayWithObjects:spaceItem,labelItem,spaceItem2, nil] animated:YES];
I've added a UIToolBar with a UIBarButtonItem as inputAccessoryView for a UITextView. It works fine but the UIBarButtonItem is touchable outside it's frame, perhaps 50 pixels outside to the right. It's no big deal but it annoys me. Anyone know why?
This is my code (ARC):
UIToolbar *toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, self.view.bounds.size.height, 320, 44)];
toolBar.barStyle = UIBarStyleBlack;
toolBar.translucent = YES;
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:#selector(doneWriting:)];
[toolBar setItems:[NSArray arrayWithObjects:doneButton, nil]];
self.messageTextView.inputAccessoryView = toolBar;
In iOS 6 it seems to behave as expected.
Nice tip: If you want the button to appear on the right instead of the left, use one of these:
UIBarButtonItem *flexibleSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil];
Then initialise the toolbar with:
[toolBar setItems:[NSArray arrayWithObjects:flexibleSpace, doneButton, nil]];
The toolbar seems to expand the active area of the buttons beyond their bounds if there are no other nearby buttons in the toolbar. Apple engineers must think it is better to try to guess where the user intended to press rather than not react at all.
I hope it helps you...
UIToolbar* keyboardDoneButtonView = [[UIToolbar alloc] init];
[keyboardDoneButtonView sizeToFit];
UIBarButtonItem* PrevButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:105 target:nil action:nil]; //<
UIBarButtonItem* NextButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:106 target:nil action:nil]; //>
UIBarButtonItem* doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(doneClicked:)];
UIBarButtonItem* flexSpace = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:nil action:nil];
UIBarButtonItem *fake = [[UIBarButtonItem alloc] initWithTitle:#"" style:UIBarButtonItemStylePlain target:nil action:nil] ;
[keyboardDoneButtonView setItems:[NSArray arrayWithObjects: PrevButton,fake, NextButton,fake,flexSpace,fake,doneButton,nil] animated:YES];
Use Fake Item to get exact pinch location on Button...
