Adding bar button item in navigation bar - iphone

Question

i was working with navigation bar button items.i was using the following code to do so
UIBarButtonItem *btnSave = [[UIBarButtonItem alloc]
initWithTitle:#"Save"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(save_Clicked:)];
self.navigationItem.rightBarButtonItem = btnSave;
[btnSave release];
UIBarButtonItem *btnCancel = [[UIBarButtonItem alloc]
initWithTitle:#"Cancel"
style:UIBarButtonItemStyleBordered
target:self
action:#selector(save_Clicked)];
self.navigationItem.leftBarButtonItem = btnCancel;
[btnCancel release];
my question is how to add another button just adjacent to the left bar button item.

Answer 1

To do this you need to create a toolbar then keep adding UIButton to it, then set the toolbar as the leftBarButton
something like this:
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, 250, 44)];
tools.tintColor = [UIColor clearColor];
[tools setTranslucent:YES];
NSMutableArray* buttons = [[NSMutableArray alloc] initWithCapacity:9];
UIImage *myImage = [UIImage imageNamed:#"AL_HomeMod_Icon.png"];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0, 0.0, myImage.size.width, myImage.size.height);
[myButton addTarget:self action:#selector(clickViewHomeMod) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *bi = [[UIBarButtonItem alloc]
initWithCustomView:myButton];
[buttons addObject:bi];
[bi release];
myImage = [UIImage imageNamed:#"AL_History_Icon.png"];
myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0, 0.0, myImage.size.width, myImage.size.height);
[myButton addTarget:self action:#selector(clickViewHistory) forControlEvents:UIControlEventTouchUpInside];
bi = [[UIBarButtonItem alloc]
initWithCustomView:myButton];
[buttons addObject:bi];
[bi release];
myImage = [UIImage imageNamed:#"AL_RX_Icon.png"];
myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0, 0.0, myImage.size.width, myImage.size.height);
[myButton addTarget:self action:#selector(clickViewCustomPopView2) forControlEvents:UIControlEventTouchUpInside];
bi = [[UIBarButtonItem alloc]
initWithCustomView:myButton];
[buttons addObject:bi];
[bi release];
myImage = [UIImage imageNamed:#"AL_User_Icon.png"];
myButton = [UIButton buttonWithType:UIButtonTypeCustom];
[myButton setImage:myImage forState:UIControlStateNormal];
myButton.showsTouchWhenHighlighted = YES;
myButton.frame = CGRectMake(0.0, 0.0, myImage.size.width, myImage.size.height);
[myButton addTarget:self action:#selector(clickViewCustomPopView:) forControlEvents:UIControlEventTouchUpInside];
bi = [[UIBarButtonItem alloc]
initWithCustomView:myButton];
[buttons addObject:bi];
popButton = myButton;
[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];
hope that help

Answer 2

Create a button as
UIBarButtonItem *logoutButton = [[UIBarButtonItem alloc]
initWithImage:[UIImage imageNamed:#"logout.png"]
style:UIBarButtonItemStylePlain
target:self action:#selector(doLogout)];
Add this button to right of navigation bar
self.navigationItem.rightBarButtonItem = logoutButton;
or add this button to left side of navigation bar
self.navigationItem.leftBarButtonItem = logoutButton;
doLogout is a function which will be called on touch logout button

I achieved my task by using the following code :
UIToolbar *tools=[[UIToolbar alloc]initWithFrame:CGRectMake(0, 0, 150, 44)];
tools.backgroundColor=[UIColor clearColor];
[tools setTranslucent:YES];
UIBarButtonItem *optionBtn=[[UIBarButtonItem alloc]initWithTitle:#"Options" style:UIBarButtonItemStyleBordered target:self action:#selector(optionPressed:)];
UIBarButtonItem *doneBtn=[[UIBarButtonItem alloc]initWithTitle:#"Done" style:UIBarButtonItemStyleBordered target:self action:#selector(donePressed:)];
NSArray *buttons=[NSArray arrayWithObjects:optionBtn,doneBtn, nil];
[tools setItems:buttons animated:NO];
self.navigationItem.rightBarButtonItem=[[UIBarButtonItem alloc]initWithCustomView:tools];
NOTE:From IOS 5.0 onwards, apple has done it lot easier . It can be done as
self.navigationItem.rightBarButtonItems=[NSArray arrayWithObjects:optionBtn,doneBtn, nil];

Answer 4

Create a custom view with two buttons and use UIBarButtonItem's initWithCustomView: initializer. That should do it.
