I try to get backBarButtonItem width:
UIBarButtonItem *leftBtn = self.navigationItem.backBarButtonItem;
UIView *view = [leftBtn valueForKey:#"view"];
CGFloat width;
if(view){
width=view.frame.size.width;
}
NSLog(#"width %f", width);
but in console: width 0.000000
Any ideas what I might be doing wrong? With self.navigationItem.rightBarButtonItem it's work.
UIButton *addButton = [UIButton buttonWithType:UIButtonTypeCustom];
CALayer *btnLayer = [addButton layer];
[btnLayer setMasksToBounds:YES];
[btnLayer setCornerRadius:1.0f];
[addButton setFrame:CGRectMake(0, 0, 45, 30)];
[addButton setBackgroundColor:[UIColor orangeColor]];
[addButton setTitle:#"Title" forState:UIControlStateNormal];
addButton.titleLabel.font = [UIFont systemFontOfSize:14.0];
[addButton addTarget:self action:#selector(Onclickevent:) forControlEvents:UIControlEventTouchUpInside];
UIBarButtonItem *barButtonItem = [[UIBarButtonItem alloc] initWithCustomView:addButton];
[self.navigationItem setRightBarButtonItem:barButtonItem];

I'm trying to add a centered button in my navbar header, confused as to how I can do it
- (void)viewDidLoad {
[super viewDidLoad];
UIImage *meImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:#"%#/me.png", kSelfBundlePath]];
UIBarButtonItem *meButton = [[UIBarButtonItem alloc] initWithImage:meImage style:UIBarButtonItemStylePlain target:self action:#selector(twitterButton)];
[self.titleView //i read this can be used to like set it but i havent been able to figure it out
help would be appreciated, pretty new
check this code
UIView *container = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 44)];
container.backgroundColor = [UIColor clearColor];
UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0, 0, 44, 44)];
[btn setBackgroundImage:[UIImage imageNamed:#"button0.png"] forState:UIControlStateNormal];
[btn addTarget:self action:#selector(btnAction:) forControlEvents:UIControlEventTouchUpInside];
[btn setShowsTouchWhenHighlighted:YES];
[buttonContainer addSubview:button0];
//add your spacer images and button1 and button2...
self.navigationItem.titleView = container;
You can try like this way
UIView *topView = [[UIView alloc]initWithFrame:CGRectZero];
UIButton * button = [[UIButton alloc]initWithFrame:CGRectZero];
[button addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Title here" forState:UIControlStateNormal];
[button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[button sizeToFit];
[topView addSubview:button];
[topView sizeToFit];
self.navigationItem.titleView = topView;
-(void)buttonAction:(Id) sender {
NSLog(#"button clicked");
}
I think its pretty straight, you can use titleView property of UINavigationItem :
-(void)addCenterButton {
UIImage *meImage = [[UIImage alloc] initWithContentsOfFile:[NSString stringWithFormat:#"%#/me.png", kSelfBundlePath]];
UIButton *button = [[UIButton alloc] initWithFrame::CGRectMake(0, 0, 40, 20)];
[button setImage:meImage forState:UIControlStateNormal];
[button addTarget:self action:#selector(twitterButton) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.titleView = button;
}
I have implement custom back Navigation bar button.
Codes:
-(UIBarButtonItem*) logicToAddBackButton {
UIImageView *imageView=[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"UiNavigationBack"]];
UILabel *label=[[UILabel alloc] init];
[label setTextColor:[UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0]];
[label setText:#"Home"];
[label sizeToFit];
int space=6;
label.frame=CGRectMake(imageView.frame.origin.x+imageView.frame.size.width+space, label.frame.origin.y, label.frame.size.width, label.frame.size.height);
UIView *view=[[UIView alloc] initWithFrame:CGRectMake(0, 0, label.frame.size.width+imageView.frame.size.width+space, imageView.frame.size.height)];
view.bounds=CGRectMake(view.bounds.origin.x+8, view.bounds.origin.y-1, view.bounds.size.width, view.bounds.size.height);
[view addSubview:imageView];
[view addSubview:label];
UIButton *button=[[UIButton alloc] initWithFrame:view.frame];
[button addTarget:self action:#selector(eventBack) forControlEvents:UIControlEventTouchUpInside];
[view addSubview:button];
[UIView animateWithDuration:0.33 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
label.alpha = 0.0;
CGRect orig=label.frame;
label.frame=CGRectMake(label.frame.origin.x+25, label.frame.origin.y, label.frame.size.width, label.frame.size.height);
label.alpha = 1.0;
label.frame=orig;
} completion:nil];
UIBarButtonItem *backButton =[[UIBarButtonItem alloc] initWithCustomView:view];
return backButton;
}
self.navigationItem.leftBarButtonItem = [self logicToAddBackButton];
This is how it look and work fine according to the logic.
Issue: If we click on first half of arrow, the back button do not respond.
Please suggest on this.
Try to set to your button:
button.contentEdgeInsets = UIEdgeInsetsMake(<#CGFloat top#>, <#CGFloat left#>, <#CGFloat bottom#>, <#CGFloat right#>)
I think you miscalculating frame somewhere.
Why don't you add UIButton instead? It will be much easier, but without label animation.
UIButton *button = [[UIButton alloc] init];
[button addTarget:self action:#selector(eventBack:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:#"Home" forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:#"UiNavigationBack"] forState:UIControlStateNormal];
[button setTitleColor:[UIColor colorWithRed:0.0 green:122.0/255.0 blue:1.0 alpha:1.0] forState:UIControlStateNormal];
[button sizeToFit];
UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithCustomView:button];
return backButton;
i have applied a code to add a uibutton to uibarbuttonitem and the problem is that the button is coming out of frame
the code is
a1 = [UIButton buttonWithType:UIButtonTypeCustom];
[a1 setFrame:CGRectMake(0.0f, 0.0f, 65.0f, 63.0f)];
[a1 addTarget:self.slideMenuController action:#selector(toggleMenu) forControlEvents:UIControlEventTouchUpInside];
[a1 setImage:[UIImage imageNamed:#"menu-enable-bt.png"] forState:UIControlStateNormal];
UIView *view =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 65.0,63.0) ];
[view addSubview:a1];
menuButton = [[UIBarButtonItem alloc] initWithCustomView:view];
rootViewController.navigationItem.leftBarButtonItem = menuButton;
i dont know whats wrong
UINavigationBar height is 44,you set frame (0.0, 0.0, 65.0,63.0),change frame height to fit in UINavigationBar
try this..
a1 = [UIButton buttonWithType:UIButtonTypeCustom];
[a1 setFrame:CGRectMake(0.0f, 0.0f, 30.0f, 30.0f)];
[a1 addTarget:self.slideMenuController action:#selector(toggleMenu) forControlEvents:UIControlEventTouchUpInside];
[a1 setImage:[UIImage imageNamed:#"menu-enable-bt.png"] forState:UIControlStateNormal];
UIView *view =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 35.0,35.0) ];
[view addSubview:a1];
menuButton = [[UIBarButtonItem alloc] initWithCustomView:view];
rootViewController.navigationItem.leftBarButtonItem = menuButton;
Did u try lowering the height in the CGRectMake(0.0, 0.0, 65.0,63.0) ? And yes, u are likely leaking the view and menuButton.
Also instead of -
a1 = [UIButton buttonWithType:UIButtonTypeCustom];
[a1 setFrame:CGRectMake(0.0f, 0.0f, 65.0f, 63.0f)];
[a1 addTarget:self.slideMenuController action:#selector(toggleMenu) forControlEvents:UIControlEventTouchUpInside];
[a1 setImage:[UIImage imageNamed:#"menu-enable-bt.png"] forState:UIControlStateNormal];
UIView *view =[[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 65.0,63.0) ];
[view addSubview:a1];
menuButton = [[UIBarButtonItem alloc] initWithCustomView:view];
you can just give menuButton = [[UIBarButtonItem alloc] initWithCustomView:a1]; and then -
rootViewController.navigationItem.leftBarButtonItem = menuButton;
[menuButton release];
Try like this...
UIButton * a1 = [UIButton buttonWithType:UIButtonTypeCustom];
[a1 setFrame:CGRectMake(0.0f, 0.0f, 65.0f, 33.0f)];
[a1 addTarget:nil action:nil forControlEvents:UIControlEventTouchUpInside];
[a1 setImage:[UIImage imageNamed:#"sc.png"] forState:UIControlStateNormal];
UIBarButtonItem* menuButton = [[UIBarButtonItem alloc] initWithCustomView:a1];
self.navigationItem.leftBarButtonItem = menuButton;
I have about 10-12 buttons that I'm adding to my scrollview. How can I make these into an array of buttons so that I can simplify the code? As of right now my code(only first three buttons are shown) is as follows:
UIButton *redButton =[UIButton buttonWithType:UIButtonTypeRoundedRect];
redButton.frame = CGRectMake(0, 0, 50, 30);
redButton.tag = 2;
[redButton setTitle:#"red" forState:UIControlStateNormal];
redButton.backgroundColor = [UIColor redColor];
[redButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[redButton addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.scollView addSubview:redButton];
UIButton *blueButton =[UIButton buttonWithType:UIButtonTypeRoundedRect];
blueButton.frame = CGRectMake(70, 0, 50, 30);
blueButton.tag = 3;
[blueButton setTitle:#"blue" forState:UIControlStateNormal];
blueButton.backgroundColor = [UIColor blueColor];
[blueButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[blueButton addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.scollView addSubview:blueButton];
UIButton *greenButton =[UIButton buttonWithType:UIButtonTypeRoundedRect];
greenButton.frame = CGRectMake(140, 0, 50, 30);
greenButton.tag = 5 ;
[greenButton setTitle:#"green" forState:UIControlStateNormal];
greenButton.backgroundColor = [UIColor greenColor];
[greenButton setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
[greenButton addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[self.scollView addSubview:greenButton];
...
Can you see if this is possible
- (void)addButtonsToScrollView
{
NSArray *buttons = #[#{#"Tag":#2,#"Title":#"red",#"Color":[UIColor redColor]},
#{#"Tag":#3,#"Title":#"blue",#"Color":[UIColor blueColor]},
#{#"Tag":#5,#"Title":#"green",#"Color":[UIColor greenColor]}];
CGRect frame = CGRectMake(0.0f, 0.0f, 50.0f, 30.0f);
for (NSDictionary *dict in buttons)
{
UIButton *button =[UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = frame;
button.tag = [dict[#"Tag"] integerValue];
[button setTitle:dict[#"Title"]
forState:UIControlStateNormal];
button.backgroundColor = dict[#"Color"];
[button setTitleColor:[UIColor blackColor]
forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonAction:)
forControlEvents:UIControlEventTouchUpInside];
[self.scrollView addSubview:button];
frame.origin.x+=frame.size.width+20.0f;
}
CGSize contentSize = self.scrollView.frame.size;
contentSize.width = frame.origin.x;
self.scrollView.contentSize = contentSize;
}
You can use:
[NSArray arrayWithObjects:redButton,greenButton,blueButton,nil];
But might be better off using a NSDictionary
[NSDictionary dictionaryWithObjectsAndKeys:
redButton, #"red",
blueButton, #"blue",
greenButton, #"green",
nil];
That way you can use the key to look them up instead of index.
Ok, we have the solution, try this code mate,
-(void) createButtons{
NSDictionary *buttonColors = #{#"Red":[UIColor redColor],#"Green":[UIColor greenColor],#"Black":[UIColor blackColor],#"Yellow":[UIColor yellowColor],#"Blue":[UIColor blueColor]};
int tag = 1;
for(NSString *key in buttonColors.allKeys){
UIColor *color = [buttonColors objectForKey:key];
UIButton *button =[UIButton buttonWithType:UIButtonTypeRoundedRect];
CGRect frame = CGRectMake(((tag -1)*70), 0, 50, 30);
[button setFrame:frame];
button.tag = tag;
button.backgroundColor = color;
[button setTitleColor:color forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonAction:) forControlEvents:UIControlEventTouchUpInside];
[button setTitle:key forState:UIControlStateNormal];
[self.scrollView addSubview:button];
tag++;
}
}
I have added a few buttons to the right side of the navigation bar with the following:
UIView* customView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 44)];
customView.backgroundColor = [UIColor clearColor];
UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 45, 44);
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
button.backgroundColor = [UIColor clearColor];
[button setImage:[UIImage imageNamed:#"toc.png"] forState:UIControlStateNormal];
button.userInteractionEnabled = YES;
[button addTarget:self action:#selector(tableOfContentsAction) forControlEvents:UIControlEventTouchUpInside];
[customView addSubview:button];
button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(50, 0, 45, 44);
button.contentHorizontalAlignment = UIControlContentHorizontalAlignmentCenter;
button.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
button.backgroundColor = [UIColor clearColor];
[button setImage:[UIImage imageNamed:#"bookmark.png"] forState:UIControlStateNormal];
button.userInteractionEnabled = YES;
[button addTarget:self action:#selector(bookmarkButtonAction) forControlEvents:UIControlEventTouchUpInside];
[customView addSubview:button];
UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:customView];
self.navigationItem.rightBarButtonItem = segmentBarItem;
[customView release];
[segmentBarItem release];
This works well. For both buttons I show a popOver as shown below
- (void) bookmarkButtonAction
{
BookmarksViewController* content = [[BookmarksViewController alloc] initWithOrientation:lastOrientation selectedPage:selectedPage];
UIPopoverController* aPopover = [[UIPopoverController alloc] initWithContentViewController:content];
CGSize size = content.view.frame.size;
aPopover.popoverContentSize = size;
aPopover.delegate = self;
self.bookmarksPopoverVC = content;
self.bookmarksPopoverVC.popUpController = aPopover;
[content release];
[aPopover presentPopoverFromBarButtonItem:self.navigationItem.rightBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
[aPopover release];
bookmarksShowing = YES;
}
The problem is that I am using presentPopoverFromBarButtonItem:self.navigationItem.rightBarButtonItem and this shows the top arrow in the middle of the two buttons. How can I attach the arrow to each button?
instead of using this line:
aPopover presentPopoverFromBarButtonItem:self.navigationItem.rightBarButtonItem
You may better try this line:
aPopover presentPopoverFromBarButtonItem:sender
I think that would solve your problem
try this:
- (IBAction)products:(id)sender {
UIButton* btn = (UIButton *)sender;
[productsPopover presentPopoverFromRect:[btn bounds] inView:btn permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
Works like a charm
