I want to make a game title but I can't seem to make the font larger. Here's what I have. I opted to not use CGRectMake initializer setting because I wanted to just set the x and y positions, not the size of the label (which I presumed would've been dictated by the size: portion of the UIFont method below). The 100.0 is no different from size 40.0.
UILabel *title = [[UILabel alloc] init];
CGRect frame = title.frame;
frame.origin.y = 30;
frame.origin.x = 100;
title.frame= frame;
title.text = #"TWINSTONES";
title.backgroundColor = [UIColor clearColor];
title.font = [UIFont fontWithName:#"TWINSTONES" size:100.0];
[title setTextColor:[UIColor colorWithWhite:0.9 alpha:1.0]];
title.numberOfLines = 0;
[title sizeToFit];
[self.view addSubview:title];

My goal is to use title and subtitle with different font sizes in navigation controller page title (title should be bigger, subtitle should be lower accordingly).
I found example of code to implement this. The only one problem is that font size is not applied - both title and subtitle have the same font size. Like the code for font size doesn't work.
How to fix that? Thank you
// prepare title label
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = [UIColor whiteColor];
titleLabel.font = [UIFont fontWithName:#"HelveticaNeueLight" size:19.0];
titleLabel.text = locationInfo;
[titleLabel sizeToFit];
// prepare subtitle label
UILabel *subtitleLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 18, 0, 0)];
subtitleLabel.backgroundColor = [UIColor clearColor];
subtitleLabel.textColor = [UIColor whiteColor];
subtitleLabel.font = [UIFont fontWithName:#"HelveticaNeueLight" size:12.0];
subtitleLabel.text = dateInfo;
[subtitleLabel sizeToFit];
UIView *twoLineTitleView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, MAX(subtitleLabel.frame.size.width, titleLabel.frame.size.width), 30)];
[twoLineTitleView addSubview:titleLabel];
[twoLineTitleView addSubview:subtitleLabel];
float widthDiff = subtitleLabel.frame.size.width - titleLabel.frame.size.width;
if (widthDiff > 0) {
CGRect frame = titleLabel.frame;
frame.origin.x = widthDiff / 2;
titleLabel.frame = CGRectIntegral(frame);
} else{
CGRect frame = subtitleLabel.frame;
frame.origin.x = fabs(widthDiff) / 2;
subtitleLabel.frame = CGRectIntegral(frame);
}
self.navigationItem.titleView = twoLineTitleView;
It's with the setFont method, not .font
[titleLabel setFont:[UIFont fontWithName:#"HelveticaNeue-Light" size:12.0]];
And also you have an error in the font name:
it's HelveticaNeue-Light
Use SetFont instead of Font::
[titleLabel setFont:[UIFont fontWithName:#"HelveticaNeue-UltraLight" size:14.0]];
I have a label that I'm creating and displaying programmatically. It can be 1 or more lines. I want to the label to be truncated at the end if it's too long. When the label is > 1 line long the following code works fine. Create a blank project and drop this into viewDidLoad to play along at home. Any iOS or tvOS project should do.
UILabel *label = [[UILabel alloc] initWithFrame:CGRectZero];
label.numberOfLines = 2;
label.lineBreakMode = NSLineBreakByTruncatingTail;
label.backgroundColor = [UIColor blueColor];
[self.view addSubview:label];
NSDictionary *attributes = #{NSFontAttributeName:[UIFont systemFontOfSize:26.0]};
label.attributedText = [[NSAttributedString alloc] initWithString:#"The rain in Spain falls mainly on the plain." attributes:attributes];
CGSize maxLabelSize = CGSizeMake(200, CGFLOAT_MAX);
CGSize requiredSize = [label sizeThatFits:maxLabelSize];
NSLog(#"requiredSize: %#", NSStringFromCGSize(requiredSize));
label.frame = CGRectMake(50.0, 50.0, requiredSize.width, requiredSize.height);
However, if I change numberOfLines to 1 then sizeThatFits returns a size with a width wide enough to fit the entire string even though it's bigger than the width of maxLabelSize.
I can work around this by checking to see if requiredSize.width is greater than maxLabelSize.width, and adjusting appropriately, but I'd like to know why sizeThatFits behaves differently with a 1-line label than with a multi-line label. I would expect a size no greater than 200 with the height the same as the attributed string's line height.
I have no idea why sizeThatFits doesn't work, but another method textRectForBounds:limitedToNumberOfLines: does the trick. Something like
label.numberOfLines = 0;
CGSize requiredSize = [label textRectForBounds:CGRectMake(0, 0, 200, CGFLOAT_MAX) limitedToNumberOfLines:1].size;
UILabel * commlbl;
commlbl=[[UILabel alloc]initWithFrame:CGRectMake(10, commlbl1.bounds.size.height+50, commscroll.bounds.size.width-25, commscroll.bounds.size.height+70)];
[commlbl setFont:[UIFont fontWithName:#"OpenSans-Regular" size:16]];
[commlbl setTextColor:[UIColor whiteColor]];
[commlbl setTextAlignment:NSTextAlignmentCenter];
commlbl.lineBreakMode = NSLineBreakByWordWrapping;
commlbl.numberOfLines = 0;
commlbl.text = [USER_DFT GetUserDefault:#"msgString"];
CGSize maximumLabelSize = CGSizeMake(296, FLT_MAX);
CGSize expectedLabelSize = [commlbl.text sizeWithFont:commlbl.font constrainedToSize:maximumLabelSize lineBreakMode:commlbl.lineBreakMode];
//adjust the label the the new height.
CGRect newFrame = commlbl.frame;
newFrame.size.height = expectedLabelSize.height;
commlbl.frame = newFrame;
I have a custom view (titleView) that I've created for a webView on my iOS app. The titleView has two labels, a titleLabel and a subTitleLabel. If the titleLabel is too wide for the titleView, I truncate the text and have it fill the whole frame. But the problem happens whenever the titleLabel is smaller that the titleView. I get inconsistent results when I try to calculate the position of the titleLabel's frame. I just assumed I would take the difference between the width of the titelView.frame.size.width and the titleLabel.frame.size.widthand divide that by 2, but it doesn't work. I'm probably missing something stupid, but I just can't see it. One thing to note is that the subTitleLabel's seem to be positioned fairly well, and though it's not perfect, it's better than the titleLabel's.
Here are some images (I added borders to the titleView and it's subViews to help show positioning) that show positioning with various length title strings:
Code:
UIView *titleView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width - 88, 34)];
titleView.clipsToBounds = YES;
UIFont *titleFont = [UIFont systemFontOfSize:16 weight:UIFontWeightThin];
UIFont *speakerFont = [UIFont systemFontOfSize:10 weight:UIFontWeightLight];
CGSize speakerSize = [[self.speech speakerFullNameAndDate] sizeWithAttributes:#{ NSFontAttributeName : speakerFont }];
CGSize titleSize = [self.speech.title sizeWithAttributes:#{ NSFontAttributeName : titleFont }];
UILabel *titleLabel = [[UILabel alloc] init];
UILabel *subTitleLabel = [[UILabel alloc] init];
[titleView addSubview: titleLabel];
[titleView addSubview:subTitleLabel];
CGFloat titleDifference = (titleView.frame.size.width - titleLabel.frame.size.width) / 2;
titleLabel.text = self.speech.title;
titleLabel.font = titleFont;
titleLabel.textAlignment = NSTextAlignmentCenter;
titleLabel.textColor = [UIColor whiteColor];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.lineBreakMode = NSLineBreakByTruncatingTail;
// titleLabel is bigger than the titleView's frame
if (titleSize.width > titleView.frame.size.width) {
titleLabel.frame = CGRectMake(0, 0, titleView.frame.size.width - 20, 18);
} else {
// titleDifference / 3 seems to be the best number for the frame's x coordinate
titleLabel.frame = CGRectMake(titleDifference / 3, 0, titleSize.width, 18);
[titleLabel sizeToFit];
}
subTitleLabel.text = [self.speech speakerFullNameAndDate];
subTitleLabel.font = speakerFont;
subTitleLabel.textAlignment = NSTextAlignmentCenter;
subTitleLabel.textColor = [UIColor whiteColor];
subTitleLabel.backgroundColor = [UIColor clearColor];
// Again, ((titleView.frame.size.width - speakerSize.width) / 3) seems to work best, though it's far from perfect
subTitleLabel.frame = CGRectMake(((titleView.frame.size.width - speakerSize.width) / 3), 20, speakerSize.width, 12);
[subTitleLabel sizeToFit];
self.navigationItem.titleView = titleView;
You are calculating your title label origin wrong remember that any view origin is the top left corner, so your title label origin should be something like
CGFloat originX = titelView.frame.size.width/2 - titleLabel.frame.size.width/2
what you are doing is assuming a view origin is in the center of the view
I am having this peculiar behavior with UILabel. Any numberOfLines works ok, except 1. If I set the number of lines to 1 it ignores the width which I set later.
I don't understand why 1 line screws it up...
here is my code
UILabel *label = [[UILabel alloc] init];
label.backgroundColor = [UIColor greenColor];
label.text = #"here is my label with lots of text to fill, here is my label with lots of text to fill";
label.frame = CGRectMake(20, 20, 100, 0);
CGRect rect = label.frame;
label.numberOfLines = 2;
label.lineBreakMode = NSLineBreakByTruncatingTail;
[self.view addSubview:label];
rect.size.width = 100;
label.frame = rect;
[label sizeToFit];
Use this code:
UILabel *label = [[UILabel alloc] init];
label.backgroundColor = [UIColor greenColor];
label.text = #"here is my label with lots of text to fill, here is my label with lots of text to fill";
label.frame = CGRectMake(20, 20, 100, 0);
label.numberOfLines = 3;
label.lineBreakMode = NSLineBreakByTruncatingTail;
[self.view addSubview:label];
[label sizeToFit];
CGRect rect = label.frame;
rect.size.width = 100;
label.frame = rect;
With numberOfLines = 3:
With numberOfLines = 1:
If you wanna use numberOfLines = 1 in that case your text will be in one line.So please use numberOfLines = 0;
label.numberOfLines = 0;
And there is no need to again define label frame so please remove these statement.
CGRect rect = label.frame;
rect.size.width = 100;
label.frame = rect;
Use this code this is perfect..
UILabel *label = [[UILabel alloc] init];
label.backgroundColor = [UIColor greenColor];
label.text = #"here is my label with lots of text to fill, here is my label with lots of text to fill";
label.frame = CGRectMake(20, 20, 100, 0);
label.numberOfLines = 0;
label.lineBreakMode = NSLineBreakByTruncatingTail;
[self.view addSubview:label];
[label sizeToFit];
Yes, it doesn't work when numberOfLines=1
I have to add this line at the end to make it work for all cases..
label.width = min(label.width, 100)
Use this as :
UILabel *label = [[UILabel alloc] init];
label.backgroundColor = [UIColor greenColor];
label.text = #"here is my label with lots of text to fill, here is my label with lots of text to fill";
label.numberOfLines = 0;
CGSize labelSize = [label.text sizeWithFont:label.font constrainedToSize:CGSizeMake(100 , 9999) lineBreakMode:label.lineBreakMode];
float lHeight = labelSize.height;
label.frame = CGRectMake(20, 20, 100, lHeight);
label.lineBreakMode = NSLineBreakByTruncatingTail;
[self.view addSubview:label];
EDIT : - (void)sizeToFit
Description :
Resizes and moves the receiver view so it just encloses its subviews.
Call this method when you want to resize the current view so that it uses the most appropriate amount of space. Specific UIKit views resize themselves according to their own internal needs. In some cases, if a view does not have a superview, it may size itself to the screen bounds. Thus, if you want a given view to size itself to its parent view, you should add it to the parent view before calling this method.
// [label sizeToFit];
Hope it helps you.
I've read many questions on the topic but I can't seem to find what is wrong with my code:
UILabel *nameLabel = [[UILabel alloc] init];
[nameLabel setText: _nameString];
nameLabel.textAlignment = UITextAlignmentLeft;
nameLabel.contentMode = UIViewContentModeTop;
nameLabel.lineBreakMode = UILineBreakModeWordWrap;
nameLabel.numberOfLines = 0;
nameLabel.font = [UIFont fontWithName:#"Verdana" size:14];
nameLabel.backgroundColor = [UIColor clearColor];
nameLabel.textColor = [UIColor colorWithRed:0 green:0.282 blue:0.31 alpha:1];
nameLabel.autoresizingMask = UIViewAutoresizingFlexibleWidth;
CGSize maximumLabelSize = CGSizeMake(200.0f, 60.0f);
CGSize expectedLabelSize = [_nameString sizeWithFont:nameLabel.font
constrainedToSize:maximumLabelSize
lineBreakMode:nameLabel.lineBreakMode];
nameLabel.frame = CGRectMake(10, 10, expectedLabelSize.width, expectedLabelSize.height);
And although sometimes it does work (on larger texts) on texts like "Airplanes being the future" the expectedLabelSize returns height 18.0f and it cuts the sentence on the "Airplanes being the"
What am I doing wrong here?
I had the same problem once, that was because my label's width was smaller than the maximum Label's width wat I used to calculate the "expectedLabelSize".
Since you are using an autoresizingMask your label might be too small.
