Within my app, the title for each navigation controller is set in either loadView or viewDidLoad
When the view controller is displayed, the title is always truncated - even though the content is not very long ("lessons" in this case).
I'm using a custom font - could that case this?
I'm also using PixateFreestyle though I don't know of any bugs with that.
Please tell me there's a solution to this that isn't creating a custom titleView label?
Thanks in advance
Try calling sizeToFit on the UILabel custom fonts shouldn't be an issue.
e.g.
#label = UILabel.alloc.initWithFrame(CGRectZero)
#label.text = "A very long string that shouldn't get truncated"
#label.sizeToFit
Alternatively, #label.adjustsFontSizeToFitWidth = true. That way, if the title is excessively long, the font will be resized in order to allow it to fit. I've never tried this with Pixate, but it works in plain vanilla iOS.

HI, i set my uisegmentedcontrol's width manually, but when the width gets too small, the words becomes ...
Is that anyway that it won't behave in this way? Instead, i just want to show the text just like the picture shown below.
I'd suggest changing your design here and going for a different approach.
The design that you seem to want makes readability pretty much impossible.
Plus, what happens if I'm using your app and add another "Active Project". What happens if I have 10 active projects?
Take the fact that the UI does not work as a sign that you are using the wrong UI for the problem you are trying solve.
I'd suggest possibly just have the current project title here with a button to maybe present a list of projects to switch to... or something.
The text has been truncated. If you want it to fit your segment, you need to update the segment control size based on the text length. If you just want to get rid of truncation, you can use the following snippet. However, it's not recommended, as later Apple might change the UISegmentControl hierarchy.
for item in segmentedControl.subviews {
for subview in item.subviews {
if subview.isKind(of: UILabel.self) {
let _label = subview as! UILabel
_label.numberOfLines = 0
_label.lineBreakMode = .byWordWrapping
}
}
}
I have this issue with a custom UIView where I have a UIButton subview, I want to set the button's text on initialization based on some condition like this:
- (void)awakeFromNib {
[super awakeFromNib];
//check for some conditions
self.testButton.titleLabel.text=#"Some Title";
}
Nothing happens and the button's text is the same as defined in the nib file, however if I change the implementation to:
- (void)awakeFromNib {
[super awakeFromNib];
//check for some conditions
[self.testButton setTitle:#"Some Title" forState:UIControlStateNormal];
}
It works as expected.
Can somebody please explain to me the difference between the two approaches? and when to use each?
EDIT:
the suggested answer doesn't explain my situation, I tested changing the button's text from another button's action like this:
- (IBAction)otherButtonClicked:(id)sender {
self.testButton.titleLabel.text=#"Some Title";
}
and the button's text changed. I just want to understand that behaviour.
Exact answer is
titleLabel
Do not use the label object to set the text color or the shadow color. Instead, use the setTitleColor:forState: and setTitleShadowColor:forState: methods of this class to make those changes.
The titleLabel property returns a value even if the button has not
been displayed yet. The value of the property is nil for system
buttons.
setTitle
Use this method to set the title for the button. The title you specify
derives its formatting from the button’s associated label object. If
you set both a title and an attributed title for the button, the
button prefers the use of the attributed title over this one.
At a minimum, you should set the value for the normal state. If a
title is not specified for a state, the default behavior is to use the
title associated with the UIControlStateNormal state. If the value for
UIControlStateNormal is not set, then the property defaults to a
system value.
Title label access is given to adjust other properties of the label such as font but setting titleLabel text does not work.
It is because UIButton class has inner implementation to set the text based on different states of the button like selected/highlighted etc which overrides label text.
The accepted answer is correct, I just add this here to elaborate a bit (comments are too short)
There's not much to explain here. The title is simply not meant to set the text at all. My guess is that the internal workings of UIButton make it save the text somewhere else as well (for different states). It uses a normal UILabel to eventually display that, because that's convenient and easy to understand. Setting the text of that does not change the button in all cases, which probably ultimately depends on the drawing cycle. I assume when it's drawn, laid out, or the like it "replaces" the label's text with its other saved variant at some point.
Now you might wonder why Apple did then expose the UILabel and thus seemed to make the text editable then.
Legacy is probably one aspect of this decision (IIRC you could once set the button's title that way). Although old code doesn't result in the desired behavior, it at least didn't crash immediately. Also, a lot of code simply wants to get the text and expects a label, that works perfectly fine as ever.
Second, designing it totally different seems overkill. To avoid that, they would have to use a subclass of UILabel which prevents you from setting the text or something and use that. Or skip it (and thus legacy support) completely and only offer the setTitle:forState: method. That seems like a bit much for a simple text container like a Label.
Ultimately it's a design choice made by Apple. You can't set the title text directly and there's no case in which you should do it any way other than by using setTitle:forState:
Wondering if anyone know hows to complete the following...
In a Storyboard I set my Labels with dummy text, they are not Static text. For example 'User1 Username'.
What I would to know if there is a setting to clear the value of this label when it is loaded by the view. I have some other code that runs off and collects the relevant information. However, it might take a few seconds so a HUD is shown to the user whilst it loads.
Of course in the background of the HUD you can see the example text shown. I know in viewDidLoad I could simply clear all the label texts setting them back to #"", but is there no setting in the storyboard or anything for this?
You can use User Defined Runtime Attributes to achieve this. Simply set "text" attribute for any UILabel, UITextField or UITextView to get what you want:
KVC and runtime attributes are really powerfull when working with Storyboard (e.g. did you know that you can set "layer.cornerRadius" attribute to any UIView to get rounded corners?).
Unfortunately, there is no other way to do it.
You would have to set the text of the UILabel manually in the ViewDidLoad method:
- (void)viewDidLoad
{
[super viewDidLoad];
self.myLabel.text = #"";
}
i am in need to use a text field in my application but the ones provided by XCode are only 1 line long and you can only change the width but not the hight.
I was wondering if its possible to make it look more lines long?
Is it only possible with customization and if yes any good tutorials?
Thank you!
First off, you can actually change the height of a UITextField. Just change the border style in the Attributes Inspector to anything except the default "rounded corners". You can then resize it right in Interface Builder. If you really wanted to, you could even change it back in your viewDidLoad method like this:
self.myTextField.borderStyle = UITextBorderStyleRoundedRect;
However, to have multiple lines, you have to use a UITextView. It's by default multi-line, but see the Apple documentation for more information.
You can use a UITextView. The document about it here. If you need something else, please post an image of what you want to achieve.
I have a XIB file of type View XIB. In it I have a View controller, and in the View controller I have a label.
I have long text that I want to break, but it doesn't - it gets truncated.
I tried this solution - I did it in the attribute window - but it doesn't help.
You could use a TextView and disable the Editable and User Interaction Enabled options in IB.
use this
myLabel.lineBreakMode = UILineBreakModeWordWrap;
if you are worried about backwards compatibility use this because the comand i mentioned before was introduced in iOS 6.0
myLabel.numberOfLines = 0;
I have been running into a similar problem. I started out with a label, but wanted multi-lines and a UITextView worked great for this, at first. Because I am using a third party library (MBProgressHUD) to handle stuff like progress messages and what not, I had thread problems when trying to update a UITextView and show the progress message at the same time.
So I went back to UILabel which actually didn't have thread problems. I found a property to allow a specific number of lines of my choosing, and had to create the label big enough to display those lines. The downfall to this approach is that I don't get the context menus like Copy, Paste, etc. but more importantly I'm not running into thread problems. I can always embed this into a UIScrollView in the future if I so choose.
You could check out my category for UILabel on GitHub. https://gist.github.com/1005520
This lets you resize the height of the label to accommodate the content.
From the Attiribute inspector, choose LineBreaks->Word Wrap option when you have selected the lablel. Also increase the number of lines Label->Lines.
Try Following steps to solve issue :
Drag out a UITextView.
Double-click it to edit text, place cursor where you want the
paragraph break.
Option-Enter a couple of times to create a blank line & paragraph.
