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];

You can use a toolbar as an accessoryview of UITextfield with UIBarButtonSystemItemCamera
toolbar = [[UIToolbar alloc] init];
toolbar.barStyle = UIBarStyleBlackOpaque;
[toolbar sizeToFit];
toolbar.frame = CGRectMake(0, 436, 320, 44);
UIBarButtonItem *spaceItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
spaceItem.width = 130.0;
UIBarButtonItem *cameraItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCamera target:self action:#selector(captureBarItemPressed:)];
NSArray *items = [NSArray arrayWithObjects: spaceItem, cameraItem, nil];
[toolbar setItems:items];
txtField.inputAccessoryView = toolbar
I try to add UINavigationBar programmatically and set bar button items.
I tried:
self.artificialNavBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
self.artificialNavBar.backgroundColor = [UIColor whiteColor];
UIBarButtonItem *bbiDone = [[UIBarButtonItem alloc] initWithTitle:#"Готово" style:UIBarButtonItemStyleDone target:nil action:nil];
UIBarButtonItem *bbiTry = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleDone target:nil action:nil];
UINavigationItem *navItem = [[UINavigationItem alloc] init];
navItem.leftBarButtonItem = bbiDone;
navItem.rightBarButtonItem = bbiTry;
self.artificialNavBar.items = #[ navItem ];
[self.view addSubview:self.artificialNavBar];
However, only left bar button appears, right one is hidden. Did i miss something?
Declare
#property (nonatomic, strong) UINavigationItem *navItem;
in the .h file of this class where you have written all these and then replace your code with below code.
self.artificialNavBar = [[UINavigationBar alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, 44)];
self.artificialNavBar.backgroundColor = [UIColor whiteColor];
[self.view addSubview:self.artificialNavBar];
UIBarButtonItem *bbiDone = [[UIBarButtonItem alloc] initWithTitle:#"Готово" style:UIBarButtonItemStyleDone target:nil action:nil];
UIBarButtonItem *bbiTry = [[UIBarButtonItem alloc] initWithTitle:#"Cancel" style:UIBarButtonItemStyleDone target:nil action:nil];
self.navItem = [[UINavigationItem alloc] init];
[self.navItem setLeftBarButtonItem:bbiDone animated:NO]
[self.navItem setRightBarButtonItem:bbiTry animated:NO]
[self.artificialNavBar setItems:#[self.navItem] animated:NO]
and make sure the navbar is nonatomic and strong.
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 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'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...
