I am trying to set a multiline UILabel, inside an UITableCell.
That UILabel has a proportional width taking as reference the screen of the device (with a multiplier). The text inside of it can change so I need to fit on the UILabel being able to multiline when the width of the text is higher than the space of the UILabel width.
I tried using:
myLabel.lineBreakMode = .byWordWrapping
myLabel.numberOfLines = 0
myLabel.sizeToFit()
but it is always displayed on one line truncating the text that overflows the UILabel width.
How can I make my UILabel to be multiline?
EDIT: I cannot put breaklines to my text because I retrieve my texts from my database.
Thanks in advance!
These two lines are necessary for calculating the cell height automatically. Put these in viewDidLoad.
self.tableView.estimatedRowHeight = 50.0
self.tableView.rowHeight = UITableViewAutomaticDimension
If you want a label to switch from one line to multiple lines, you either have to specify line breaks in the text of the string with \n or newline char, or you can set constraints for the width of the label, or you can set leading and trailing constraints for the label. If one of those methods is complete, the label will go to as many lines as it takes to hit the max number of lines or infinite if set to 0.
Finally I was able to make my multiline UILabel adding this code:
self.tableView.estimatedRowHeight = 50.0
and reducing the multiplier value. It seems that the text could not fit on the height of the UITableCell.
I have UILabel (in UIScrollView) with
self.testlabel.numberOfLines = 0;
self.testlabel.sizeToFit()
and text with 26455 characters, when I set text to label :
self.testlabel.text = content
I don't see my text, but if text is much smaller than 26455 characters then all fine.
So, how to place a big text in XCode?
Check whether the label height constraint is fixed.
Try adjusting the scrollview content size depending on the text height.
I have a label, if i add text to label it added one extra space at the beginning of the text, app supports only portrait orientation. tried following solutions but no use. attached images for reference.
I have created this label in xib with
number of lines 2
with constrains leading, trailing, bottom space to container, height is not fixed,
and set text like
dealName.text = "Cup of Coffee with A asdf asd asdf adsf ads fad"
UILabel extra spaces before and after text ios
UIlabel shows extra space before text
UILabel with multiple lines
UILabel with single line
try this may be there is an any white space before character this will remove this..
NSString *trimmed = [yourstring stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
yourlable.text = trimmed;
OR
Also see if you set attribute paragraph spacing from here..
I'm using a UILabel in collection view cell which is centre aligned and has multiple lines. I'm using adjustFontSizeToFitWidth = YES and minimumFontScale = 0.5 to reduce the font size when text does not fit. This works fine in iOS 7.
But in iOS 6 the text alignment goes to the left. To align it to centre I used adjustLetterSpacingToFitWidth = NO which I found in other threads, this aligns the text to centre but the text doesn't fit and leaves a "..." trail in the end.
Thanks for the help!
You could use a UITextView which will allow you to wrap the text, unlike the UILabel. If you want all of your text on one line you could make it so that in iOS 7 the text is shrunk one amount and in iOS 6 it is shrunk more.
Now UILabel has [textLabel sizeToFit]; for label size changing also you can use following code:
textLabel.adjustsFontSizeToFitWidth = YES;
textLabel.numberOfLines = 0;
[textLabel sizeToFit];
I have a non-scrollable UITextView embedded in a UIScrollView and add text to the UITextView dynamically. The UIScrollView adjust it's contentSize accordingly based on the TextView's frame. However, once the UITextView exceeds a height of 8192, the text will become invisible (but still there, because you can use the magnifying glass to highlight text and even see parts of the text through the magnifying glass).
CGRect textviewFrame = self.TextView.frame;
textviewFrame.size.height = [self textViewHeightForAttributedText:self.TextView.attributedText andWidth:320.0];
self.TextView.frame = textviewFrame;
self.ScrollView.contentSize = self.TextView.frame.size;
Helper function to size UITextView accordingly:
- (CGFloat)textViewHeightForAttributedText:(NSAttributedString *)text andWidth:(CGFloat)width
{
UITextView *textView = [[UITextView alloc] init];
[textView setAttributedText:text];
CGSize size = [textView sizeThatFits:CGSizeMake(width, FLT_MAX)];
return size.height;
}
Didn't realize it was the same exact problem that was unsolved here until I tested it out explicitly by forcing the max size to 8193 and the problem occurred (while a max size of 8192 still had the text showing correctly). Anyone run into this problem before and know of a work around? Thanks
I was recently hit by this problem and have worked out an effective way around it. Although it seems like an iOS bug IMHO it's really not... there are practical limits to CALayer sizes, plus drawing an 8K high piece of text takes a long time. Much better to do as Apple intended and to only render the bit of text that's visible... that's why UITextView extends UIScrollView after all.
The problem is that UITextView isn't terribly easy to integrate with other bits of UI. In my case I am working on a news app where a single UITextView is used to render the article, plus there's some separate UI (titles and buttons etc) above and below it, all hosted in a single scrollable container.
The solution I've found is to split the UITextView into two views... a dedicated UITextView container whose frame is the full text size (i.e. the same size your UITextView's contentSize) and which is the superview of your UITextView. Your child UITextView's frame should be set to the bounds of the outer scrollable container.
Then all you have to do is use key-value observation to monitor the contentOffset property of your outer scrollable container view (in my case this is a UICollectionView). When its contentOffset changes you update (1) the contentOffset of your UITextView, and (2) the transform property of the UITextView's layer. By updating that transform property the UITextView is fixed to fill the currently-visible part of it's superview. But because you're also updating the UITextView's contentOffset, this trickery is totally invisible to the user... it looks and behaves as if the UITextView is simply very large.
Here's a fully functional solution, for anyone who'd like it!
** Assuming your content size will not exceed the limits of two text views **
This solution works by adding two UITextViews to your view, and splitting your text between them. It looks complicated, but it's actually very simple! I've just written a very verbose description :)
Step 1 - Add two UITextViews to your view:
I added mine in my storyboard. Place them so that one is directly above the other, with no space between them. Don't worry about setting the height (we will set that later).
Set constraints on the views so that they are tied to each other from the top and bottom, and the surrounding edges of the container from all other sides, including your desired padding. i.e. tie the first text view to the container from the top, left, and right, and to the second text view from the bottom. Tie the second text view to the container from the bottom, left, and right, and to the first text view from the top. This will ensure that they stretch appropriately when the content is set.
Don't set any constraints on the height of the views, or if you must (to avoid warnings from the constraints inspector), set the height of one of the views to be >= 20, or some similarly small number.
Disable scrolling, bouncing, and scrolling indicators for both your text views. This solution relies on the views being a fixed, non-scrollable height, so if you'd like your content to scroll, you should use a UIScrollView or UITableViewCell as a container.
Create outlets for your two new text views in your view controller file, naming them something like textView1 and textView2.
Step 2 - Set textContainerInsets to zero:
Set the textContainerInset property on both text views to zero, either using User Defined Runtime Attributes:
or code:
self.textView1.textContainerInset = UIEdgeInsetsZero;
self.textView2.textContainerInset = UIEdgeInsetsZero;
This will ensure that the no visible space will appear between the two views when the content is set, and should not affect the other spacing around your views.
Step 3 - Split your content, set it, and update the view heights:
Simply copy the following code into your view controller file (viewDidLoad), and set the contentString variable to your content.
/* Content is split across two UITextViews to avoid max drawing height */
NSString *contentString = #"Some very long piece of text...";
// Set text
NSArray *components = [contentString componentsSeparatedByString:#"\n"];
NSInteger halfLength = [components count] / 2;
NSArray *firstHalf = [components subarrayWithRange:NSMakeRange(0, halfLength)];
NSArray *secondHalf = [components subarrayWithRange:NSMakeRange(halfLength, [components count] - halfLength)];
NSString *contentString1 = [firstHalf componentsJoinedByString:#"\n"];
NSString *contentString2 = [secondHalf componentsJoinedByString:#"\n"];
self.textView1.text = contentString1;
self.textView2.text = contentString2;
// Set text view heights
CGFloat fixedWidth1 = self.textView1.frame.size.width;
CGFloat fixedWidth2 = self.textView2.frame.size.width;
CGSize newSize1 = [self.textView1 sizeThatFits:CGSizeMake(fixedWidth1, CGFLOAT_MAX)];
CGSize newSize2 = [self.textView2 sizeThatFits:CGSizeMake(fixedWidth2, CGFLOAT_MAX)];
CGRect newFrame1 = self.textView1.frame;
CGRect newFrame2 = self.textView2.frame;
newFrame1.size = CGSizeMake(fmaxf(newSize1.width, fixedWidth1), MIN(newSize1.height, 8192));
newFrame2.size = CGSizeMake(fmaxf(newSize2.width, fixedWidth2), MIN(newSize2.height, 8192));
self.textView1.frame = newFrame1;
self.textView2.frame = newFrame2;
This code splits the contentString roughly in the middle, looking for the nearest newline. If you'd like to split your content on a different character, simply change all occurrences of \n above to whatever you'd like to split on.
Step 4 - Set your container view height:
Set your container view (scrollView, tableViewCell, whatever else) to the height of your two text views, plus whatever additional space you've set above and below them.
CGRect viewFrame = self.myView.frame;
viewFrame.size.height = MIN(self.textView1.frame.size.height, 8192) + MIN(self.textView2.frame.size.height, 8192) + kTextViewContainerPadding;
[self.myView setFrame:viewFrame];
(In my code, kTextViewContainerPadding is a macro I've set to the sum of the space above and below my two text views, within their container).
That's it! Good luck.
Try enabling the scroll for the scrollView.
Keep the height of the textView > height of the content, so that in reality there will be no scroll, but scrollEnabled should be = YES
It solved the problem for me.
Hello I think am not late to answer. I got the same problem like you. This is my solution:
textView.scrollEnabled = YES;
contentTextView.attributedText = finalAttrString;
// contentTextView.text = [attrString string];
contentTextView.font = kFont(contentTextFS + [valueOfStepper intValue]);
[contentTextView sizeToFit];
contentTextView.height += 1;//This is the key code
//contentTextView.height = 8192.0f
Them I solved the trouble and I can change size dynamic.Successfull on iOS 8
