I am displaying a label on UI in iOS using code, not from storyboard. When the size of the label is large then it does display accurate it go outside the view so I decided to use sizeToFit in iOS. But when I apply this thing on label then it does appear on view. Please tell why my label does not appear in this case.
Here is the code for the label:
self.label_company = [[UILabel alloc]initWithFrame:CGRectMake(60, 30, 150, 100)];
[self.label_company setFont:[UIFont fontWithName:#"HelveticaNeue" size:12]];
UILabel *label1 = [[UILabel alloc]initWithFrame:CGRectMake(60, 30, 150, 100)];
[label1 setFont:[UIFont fontWithName:#"HelveticaNeue" size:12]];
label1.text=#"yourdata";
[self.view addSubview:label1];
[label1 sizeToFit];
Make sure you have some text in your label as well as add it to your view.
You currently have no text set to the label hence calling sizeToFit is making its width 0 as there is no size of the label in terms of width.
Set self.label_company.text = #"Some text" and then call sizeToFit
Ensure that you set the text of the label before calling size to fit.

I'm creating these labels for a Storyboard view. I have autolayout set to OFF and I'm setting the numberoflines to 0 but the text is only displayed if I comment out sizeToFit. Then, of course, the text gets cut off when its height is greater than 40.
- (void)viewDidLoad
{
[super viewDidLoad];
first = #"This text fits in the label";
second = #"This large text is too large for the label but because the words are normal sized, shows the more button correctly at the bottom right";
third = #"Doesn't show the more button correctly because WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW";
firstlbl = [[UILabel alloc]initWithFrame:CGRectMake(13, 57, 295, 40)];
secondlbl = [[UILabel alloc]initWithFrame:CGRectMake(13, 152, 295, 40)];
thirdlbl = [[UILabel alloc]initWithFrame:CGRectMake(13, 225, 295, 40)];
[firstlbl setFont:[UIFont fontWithName:#"HelveticaNeue-Light" size:14]];
[secondlbl setFont:[UIFont fontWithName:#"HelveticaNeue-Light" size:14]];
[thirdlbl setFont:[UIFont fontWithName:#"HelveticaNeue-Light" size:14]];
firstlbl.lineBreakMode = NSLineBreakByWordWrapping;
secondlbl.lineBreakMode = NSLineBreakByWordWrapping;
thirdlbl.lineBreakMode = NSLineBreakByWordWrapping;
firstlbl.numberOfLines = 0;
secondlbl.numberOfLines = 0;
thirdlbl.numberOfLines = 0;
[firstlbl sizeToFit];
[secondlbl sizeToFit];
[thirdlbl sizeToFit];
[firstlbl setText:first];
[secondlbl setText:second];
[thirdlbl setText:third];
[self.view addSubview:firstlbl];
[self.view addSubview:secondlbl];
[self.view addSubview:thirdlbl];
}
You're calling sizeToFit before you set the text, so it's sizing down to CGRectZero. Switch those calls and it'll work.
sizeToFit doesn't mean "automatically adjust your size to fit your content," it means "update your size right now to fit your content." Subsequent updates to the text won't change the frame.
If you want the former behavior, so that it automatically sizes itself to its content, autolayout is probably the easiest road to take.
Any way to have multiple lines of text in UILabel ?
I dont wish to more than 1 label in the view.
How to add multiple lines in a single UILabel??
Yes there is a way. Just you need to add two property of UILabel i.e.
NumberOfLines=0 It'll allow you to add multiple lines in a UILabel
LineBreakMode = NSLineBreakByWordWrapping It'll allow you to break your sentence by word. You can also change it according to your requirement.
[YourLabel setNumberOfLines:0];
[YourLabel setLineBreakMode:NSLineBreakByWordWrapping];
You can also set this two property form your interface builder
here is a sample code
UILabel *pHolder1 = [[UILabel alloc]initWithFrame:CGRectMake(5, 0, 245, 45)];
pHolder1.backgroundColor = [UIColor clearColor];
pHolder1.font = [UIFont systemFontOfSize:14.0f];
pHolder1.numberOfLines =0;
pHolder1.lineBreakMode = NSLineBreakByWordWrapping;
pHolder1.textAlignment = NSTextAlignmentCenter;
Dynamically calculate the height of UILabel
please refer the below post
Adjust UILabel height depending on the text
Here is sample code:
UILabel *lblUsername=[[UILabel alloc] init];
StoryTextSize = [storytext sizeWithFont:[UIFont fontWithName:#"Georgia" size:13.0f] constrainedToSize:CGSizeMake(300, MAXFLOAT) lineBreakMode:NSLineBreakByWordWrapping];
lblUsername.frame=CGRectMake(20, 5, [[UIScreen mainScreen] bounds].size.width-40, StoryTextSize.height);
lblUsername.textColor=[UIColor blackColor];
lblUsername.text=[NSString stringWithFormat:#"%#",[[tblRecords objectAtIndex:indexPath.row] valueForKey:#"username"]];
lblStoryText.numberOfLines=nooflines;
lblStoryText.backgroundColor=[UIColor clearColor];
[self.view addSubview:lblStoryText];
make sure that your label height should be more so total no of lines become visible.
Well I need to change a text on my navigation control bar to fit a movie "title" longer than the space available. I've see more code for resize the text using a label like this:
UILabel *bigLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 120, 30)];
bigLabel.text = titoloSource;
bigLabel.font = [UIFont systemFontOfSize:22.0];
[bigLabel setFont:[UIFont boldSystemFontOfSize:16.0]];
[bigLabel setBackgroundColor:[UIColor clearColor]];
[bigLabel setTextColor:[UIColor whiteColor]];
[bigLabel setText:self.title];
[self.navigationController.navigationBar.topItem setTitleView:bigLabel];
self.navigationItem.titleView = bigLabel;
But I Know that the appel GUI line guide say that we can't make a small text below a certain measure. Now I've think: WHY CAN'T I MAKE an animated slider text?
So, Someone know a way to make a text animated that scroll all the "title" inside a label???
thanks
Trying to position a UILabel above some text, but the elements are "stepping" on each other. I positioned them with x,y,h,w such that they should not do this but alas, they are. You can see in the screenshot that the label text "Abalone" and the text are commingled. What changes do I need to make here? I've already tried changing the x,y,w,h values to no great effect...
txtView = [[UITextView alloc] initWithFrame:CGRectMake(10,20,280,300)];
[txtView setFont:[UIFont fontWithName:#"ArialMT" size:14]];
txtView.text = word.definition;
txtView.editable = NO;
txtView.scrollEnabled = YES;
[txtView scrollRangeToVisible:NSMakeRange([txtView.text length], 0)];
txtView.minimumZoomScale = 1;
txtView.maximumZoomScale = 10;
UILabel *wordTitle = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 250, 20)];
wordTitle.text = word.term;
[txtView addSubview:wordTitle];
[detailsViewController.view addSubview:txtView];
I think the problem is you are adding the label view as a subview to UITextview. You have to reserve some space for the label view in the UITextview. You can either add some padding to the textView, which can be confusing, because padding in UITextView is not constant and varies based on the font size. Or you can add your UILabel directly to the detailsViewController.view and start your UITextView below the label.
Hope it helps.
I do this to make my UIlabel, setting the numberOfLines to 0 so that it has no line-limit:
UILabel *nmLbl = [[UILabel alloc] initWithFrame:CGRectZero];
[nmLbl setFont:[UIFont boldSystemFontOfSize:16.0f]];
[nmLbl setNumberOfLines:0];
[self addSubview:nmLbl];
[nmLbl release];
Later on, when I know which string goes into the label, I size it like this:
nameSize = [[self name] sizeWithFont:[UIFont boldSystemFontOfSize:16.0f] constrainedToSize:maxNameSize lineBreakMode:UILineBreakModeWordWrap];
[self.nameLabel setFrame:CGRectMake(0.0f, 0.0f, nameSize.width, nameSize.height)];
[self.nameLabel sizeToFit];
Now, for my particular use, I need to know how many lines this ends up taking.
If I access the numberOfLines property of the UILabel it will always return 0.
Is there a way for me to directly access how many lines the UILabel ended up being without
having to calculate it, again, by going label.size.height / fontHeight?
Thank you in advance.
No. numberOfLines is a configuration setting, not a reflection of the current formatting.
