I want to navigationBar titleView alignment left but with no success.
How to make navigationBar titleView align left?
fream.x = negative
In my opinion, this is imprecise.(because ios version)
Increase sCustomTitleView width and check or you can try this code in viewDidLoad-
UILabel* lbl = [[UILabel alloc] initWithFrame:CGRectMake(0,0,200,40)];
lbl.textAlignment = NSTextAlignmentLeft;
lbl.text = #"My Title";
self.navigationItem.titleView = lbl;

I am trying to add an image on navigation bar but the dimensions are wrong.
UIImageView* menuButton=[[UIImageView alloc]initWithFrame:CGRectMake(4, 7, 20, 20)];
menuButton.image=[UIImage imageNamed: Model.icon.MapList];
UIBarButtonItem *accountBarItem = [[UIBarButtonItem alloc] initWithCustomView:menuButton];
self.navigationItem.leftBarButtonItem = accountBarItem;
It seams that I don't have any control on the dimensions of the image, because when I change the values of initWithFrame nothing changes.
Also this problem appears only on iPhones greater than iPhone 5 model.
What am I missing?
You can just use simple button and set image for it.
UIButton *b = [UIButton buttonWithType:UIButtonTypeCustom];
[b setFrame:CGRectMake(0.0f, 0.0f, 25.0f, 25.0f)];
[b addTarget:self action:#selector(randomMsg) forControlEvents:UIControlEventTouchUpInside];
[b setImage:[UIImage imageNamed: Model.icon.MapList] forState:UIControlStateNormal];
UIBarButtonItem *item = [[UIBarButtonItem alloc] initWithCustomView:b];
self.navigationItem.leftBarButtonItem = item;
If you have wrong aspect ratio , you can use
[[b imageView] setContentMode: UIViewContentModeScaleAspectFit];
I'd recommend adding a border to your image view so you can see what's going on.
Here's what you're currently experiencing (using the imageView directly as the custom view of the bar button item):
- (void)_addImageViewToLeftButtonItemWithoutOuterView {
UIImageView *profileImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Homer.jpg"]];
[profileImageView setFrame:CGRectMake(0, 0, 40, 40)];
profileImageView.layer.cornerRadius = 20.0f;
profileImageView.layer.masksToBounds = YES;
profileImageView.clipsToBounds = YES;
profileImageView.layer.borderColor = [UIColor blackColor].CGColor;
profileImageView.layer.borderWidth = 1.0f;
UIBarButtonItem *rbi = [[UIBarButtonItem alloc] initWithCustomView:profileImageView];
self.navigationItem.leftBarButtonItem = rbi;
}
This is what it looks like without aspect fit:
And with aspect fit set:
And this is what I believe you want:
- (void)_addImageViewToLeftButtonItemWithOuterView {
UIView *profileView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 40, 40)];
profileView.layer.borderColor = [[UIColor redColor] CGColor];
profileView.layer.borderWidth = 2.0f;
UIImageView *profileImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Homer.jpg"]];
profileImageView.contentMode = UIViewContentModeScaleAspectFit;
[profileImageView setFrame:CGRectMake(0, 0, 40, 40)];
profileImageView.layer.cornerRadius = 20.0f;
profileImageView.layer.masksToBounds = YES;
profileImageView.clipsToBounds = YES;
profileImageView.layer.borderColor = [UIColor blackColor].CGColor;
profileImageView.layer.borderWidth = 1.0f;
[profileView addSubview:profileImageView];
UIBarButtonItem *lbi = [[UIBarButtonItem alloc] initWithCustomView:profileView];
self.navigationItem.leftBarButtonItem = lbi;
}
Which results in this:
As you probably noticed, the sorta trick here is that you don't want to add the image view directly as the custom view within initWithCustomView of the UIBarButtonItem. Instead you want to use an outer view to hold the imageView, then you can adjust the frame of your subview to move it around.
Here's one more example if you wanted the image further to the right (obviously you won't want the border for the outer image view, but I've just left it there for demonstration purposes):
- (void)_addImageViewToLeftButtonItemWithOuterView {
// adjust this to 80 width (it always starts at the origin of the bar button item
UIView *profileView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 80, 40)];
profileView.layer.borderColor = [[UIColor redColor] CGColor];
profileView.layer.borderWidth = 2.0f;
UIImageView *profileImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Homer.jpg"]];
profileImageView.contentMode = UIViewContentModeScaleAspectFit;
// and adjust this to be offset by 40 (move it to the right some)
[profileImageView setFrame:CGRectMake(40, 0, 40, 40)];
profileImageView.layer.cornerRadius = 20.0f;
profileImageView.layer.masksToBounds = YES;
profileImageView.clipsToBounds = YES;
profileImageView.layer.borderColor = [UIColor blackColor].CGColor;
profileImageView.layer.borderWidth = 1.0f;
[profileView addSubview:profileImageView];
UIBarButtonItem *lbi = [[UIBarButtonItem alloc] initWithCustomView:profileView];
self.navigationItem.leftBarButtonItem = lbi;
}
I would like to show a small icon next to the title in my UINavigationController.
Through the magic of Photoshop, like this:
I know I need to create a new view and build the image and title into it. Here is what I am doing:
In viewDidLoad in the UINavigationController view controller, I call the method
[self setTitleBar];
Which calls this method:
- (void) setTitleBar {
CGRect navBarFrame = self.navigationController.navigationBar.frame;
//UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(navBarFrame.origin.x, navBarFrame.origin.y, (leftButtonFrame.origin.x + leftButtonFrame.size.width) - rightButtonFrame.origin.x, navBarFrame.size.height)];
UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(navBarFrame.origin.x, navBarFrame.origin.y,self.view.frame.size.width,navBarFrame.size.height)];
titleView.backgroundColor = [UIColor clearColor];
CGPoint tvCenter = CGPointMake(titleView.frame.size.width/2, titleView.frame.size.height/2);
UIImage * icon = [UIImage imageNamed:#"star"];
UIImageView *iconView = [[UIImageView alloc] initWithImage:icon];
iconView.frame = CGRectMake(0, 0, icon.size.width, icon.size.height);
UILabel *title = [[UILabel alloc] init];
title.backgroundColor = [UIColor clearColor];
title.textColor = [UIColor whiteColor];
title.textAlignment = NSTextAlignmentCenter;
title.text = #"SOME TITLE";
title.frame = CGRectMake(0, 0, 100, titleView.frame.size.height);
[title sizeToFit];
iconView.center = CGPointMake(tvCenter.x - (icon.size.width/2), tvCenter.y);
[titleView addSubview:iconView];
[titleView addSubview:title];
self.navigationItem.titleView = titleView;
}
My logic in the titleView is: Get the left most button's frame and get the right most buttons frame. THEN do some math to figure out how big the view can be. That should be the titleView's frame size.
However, I can't seem to get it to work. If I plug in a frame size of 0,0,100,40; then it shows the frame but everything is squished together. But you see it. I know that 100 should be dynamic to ensure that the title is shown.
But I can't seem to figure it out.
Any help?
You can place objects on the Navigation Controller View, as subviews.
- (void) setTitleBar {
//Let's say your icon size is 20
int starSize = 20;
//Now you'll have to calculate where to place the ImageView respect the TextSize (for this you'll need to know the text and font of your UINavigationItem title)
CGSize textSize = [#"SOME TITLE" sizeWithAttributes:#{NSFontAttributeName:[UIFont fontWithName:#"navfontname" size:15]}];
UIImageView *startImageView = [[UIImageView alloc] initWithFrame:CGRectMake(self.navigationController.view.frame.size.width/2 - textSize.width/2, self.navigationController.view.frame.size.height/2 - starSize/2, starSize,starSize)];
startImageView.image = [UIImage imageNamed:#"star"];
[self.navigationController.view addSubview:startImageView];
}
For the moment I just know how to put a string as a title with:
[self setTitle:#"iOS CONTROL"];
or an image with
self.navigationItem.titleView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"icon.png"]];
but not both in the same time
there is a solution ? Thank you
You can create a UIView and add as many subviews as you like. For example:
UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 100.0, 40.0)];
titleView.backgroundColor = [UIColor clearColor];
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"icon.png"]];
UILabel *titleLabel = [[UILabel alloc] init];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = [UIColor redColor];
titleLabel.text = #"My Title Label";
[titleLabel sizeToFit];
...
// Set the frames for imageView and titleLabel to whatever you need them to be
...
[titleView addSubview:imageView];
[titleView addSubview:titleLabel];
self.navigationItem.titleView = titleView;
Create a new UIView, add UIImage and a UILabel as subviews to it the way you want and add that UIView using self.navigationItem.titleView.
i have big Image in my app. i create it dynamically and i want to add a UILabel on this image:
UIImageView *thumbnailImage;
thumbnailImage = [[UIImageView alloc] initWithFrame:CGRectMake(xImage, yImage, imageWidth, imageHeight)];
UILabel *lblTitle = [[UILabel alloc] init];
lblTitle.text = #"SomeText";
lblTitle.frame = CGRectMake(xTitle, yTitle , titleWidth ,titleHeight);
[thumbnailImage setContentMode:UIViewContentModeScaleAspectFill];
thumbnailImage.clipsToBounds = YES;
[thumbnailImage addSubview:lblTitle];
but the [thumbnailImage addSubview:UILabel]; code does not work.
any one have any idea?
I want to add some text on bottom of picture like news article.
so I solve it with below code, if any one have a better idea please share it.
UIImageView *thumbnailImage;
thumbnailImage = [[UIImageView alloc] initWithFrame:CGRectMake(xImage, yImage, imageWidth, imageHeight)];
UIView *titleView = [[UIView alloc] initWithFrame:CGRectMake(xImage,imageHeight - titleHeight , titleWidth , titleHeight )];
UILabel *lblTitle = [[UILabel alloc] initWithFrame:CGRectMake(xTitle, yTitle , titleWidth ,titleHeight)];
titleView.alpha = 0.3;
[thumbnailImage setContentMode:UIViewContentModeScaleAspectFill];
thumbnailImage.clipsToBounds = YES;
[self.view addSubview:thumbnailImage];
[self.view addSubview:titleView];
lblTitle.textLabel.text = #"SomeText";
first I use below line of Code:
[titleView addSubview:lblTitle]
but the alpha of titleView impact lblTitle and made it transparent. so after delete this line lblTitle Text appear clear and bright.
It's better to initialize the label with it's frame.
You should add a text to the label
You should add the UILabel object (lblTitle) to the imageview instead of the UILabel type.
With these corrections, your code should look like this:
UIImageView *thumbnailImage;
thumbnailImage = [[UIImageView alloc] initWithFrame:CGRectMake(xImage, yImage, imageWidth, imageHeight)];
[thumbnailImage setContentMode:UIViewContentModeScaleAspectFill];
thumbnailImage.clipsToBounds = YES;
UILabel *lblTitle = [[UILabel alloc] initWithFrame:CGRectMake(xTitle, yTitle , titleWidth ,titleHeight)];
lblTitle.textLabel.text = #"Your text";
[thumbnailImage addSubview:lblTitle];
thumbnailImage is a UIView, so you can add subviews to it.instead of writing the line
[thumbnailImage addSubview:UILabel];
edit it with the following ::
[thumbnailImage addSubview:lblTitle];
This will work . :)
So I have an navigation bar I would like to customize and center no matter what I do I either get the image tiling like so.
Here is the code i am using to set the self.navigation.titleView in my UITableControllerView
self.navigationItem.titleView = [self titleView]; // happens in viewDidLoad
- (UIView *)titleView{
UIImage *headerImage = [UIImage imageNamed:#"header#2x"];
UIImageView *containerView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, headerImage.size.width, headerImage.size.height)];
return containerView;
}
Thanks.
UIImageView *imgtitle = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 100, 25)];
[imgtitle setContentMode:UIViewContentModeCenter];
self.navigationItem.titleView = imgtitle;
imgtitle.image = [UIImage imageNamed:#"logo.png"];
