How to programmatically add a UINavigationBar and a back button on it - iphone

Question

I am newbie trying to make an app similar to Notes app of iPhone using UITextView.
I am getting the textView and lines and it is working fine.
My problem is that I want to add a UINavigationBar and back button on it.
And I want to add a UIToolBar at the bottom and 2 toolBarItems on it how to do this programmetically. Any help will be a great push up for me..
below is the code snippet.
NoteView.h
#interface NoteView : UITextView <UITextViewDelegate,UITabBarControllerDelegate>
{
}
NoteView.m
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
self.backgroundColor = [UIColor colorWithRed:0.6f green:0.6f blue:1.0f alpha:1.0f];
self.font = [UIFont fontWithName:#"MarkerFelt-Thin" size:20];
self.contentMode = UIViewContentModeRedraw;
}
return self;
}
- (void)drawRect:(CGRect)rect {
CGContextRef context = UIGraphicsGetCurrentContext();
CGContextSetStrokeColorWithColor(context, [UIColor colorWithRed:0.0f green:0.0f blue:0.0f alpha:0.2f].CGColor);
CGContextSetLineWidth(context, 1.0f);
CGContextBeginPath(context);
NSUInteger numberOfLines = (self.contentSize.height + self.bounds.size.height) / self.font.leading;
CGFloat baselineOffset = 6.0f;
for (int x = 0; x < numberOfLines; x++) {
CGContextMoveToPoint(context, self.bounds.origin.x, self.font.leading*x + 0.5f + baselineOffset);
CGContextAddLineToPoint(context, self.bounds.size.width, self.font.leading*x + 0.5f + baselineOffset);
}
CGContextClosePath(context);
CGContextStrokePath(context);
}
AddNotesViewController.h
#interface AddNotesViewController : UIViewController <UITextViewDelegate,UITabBarDelegate>
{
NoteView *note;
}
#property (nonatomic, retain) NoteView *note;
#end
AddNotesViewController.m
- (void)loadView
{
[super loadView];
self.note = [[[NoteView alloc] initWithFrame:self.view.bounds] autorelease];
[self.view addSubview:note];
note.delegate = self;
note.text=#"";
}
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
[note setNeedsDisplay];
}
- (void)textViewDidBeginEditing:(UITextView *)textView
{
CGRect frame = self.view.bounds;
frame.size.height -= KEYBOARD_HEIGHT;
note.frame = frame;
}
- (void)textViewDidEndEditing:(UITextView *)textView
{
note.frame = self.view.bounds;
}
- (BOOL)textView:(UITextView *)textView
shouldChangeTextInRange:(NSRange)range
replacementText:(NSString *)text
{
if ([text isEqualToString:#"\n"]) {
[textView resignFirstResponder];
return NO;
}
return YES;
}

Answer 1

Navigation Bar Image
UINavigationBar *navBar = [[self navigationController] navigationBar];
UIImage *image = [UIImage imageNamed:#"TopBar.png"];
[navBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
Back Button
-(void)getBackBtn
{
UIButton *Btn =[UIButton buttonWithType:UIButtonTypeCustom];
[Btn setFrame:CGRectMake(0.0f,0.0f,50.0f,30.0f)];
[Btn setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:#"back.png"]] forState:UIControlStateNormal];
//[Btn setTitle:#"OK" forState:UIControlStateNormal];
//Btn.titleLabel.font = [UIFont fontWithName:#"Georgia" size:14];
[Btn addTarget:self action:#selector(backBtnPress:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *addButton = [[UIBarButtonItem alloc] initWithCustomView:Btn];
[self.navigationItem setLeftBarButtonItem:addButton];
}
BackButtonAction
-(IBAction)backBtnPress:(id)sender
{
}

Answer 2

use this code....
UIBarButtonItem *addButton = [[UIBarButtonItem alloc]
initWithTitle:NSLocalizedString(#"Back", #"")
style:UIBarButtonItemStyleDone
target:self
action:#selector(YourActionMethod:)];
self.navigationItem.leftBarButtonItem = addButton;
