I'm using the following code to auto adjust the height of a label in a UITableView. It works the majority of the time, but certain times text is cut off. Is there something wrong with my code, or anything else I need to add?
UILabel *textLabel = ((UILabel *)[cell viewWithTag:3]);
textLabel.text = text;
CGSize maximumLabelSize = CGSizeMake(296, FLT_MAX);
CGSize expectedLabelSize = [text sizeWithFont:textLabel.font constrainedToSize:maximumLabelSize lineBreakMode:textLabel.lineBreakMode];
//adjust the label the the new height.
CGRect newFrame = textLabel.frame;
newFrame.size.height = expectedLabelSize.height;
textLabel.frame = newFrame;
In iOS 7 sizeWithFont: constrainedToSize: lineBreakMode: is deprecated, now you should use:
CGSize maxSize = CGSizeMake(296.f, FLT_MAX);
CGRect labRect = [someText boundingRectWithSize:maxSize options:NSStringDrawingUsesLineFragmentOrigin attributes:#{NSFontAttributeName:textLabel.font} context:nil];
textLabel.frame = CGRectMake(0, 0, maxSize.width, labRect.size.height);
textLabel.text = someText;

I have no idea why the height of my UILabel is expanding to such a great height. It leaves the text of my UILabel in the centre. I don't want all of this extra space...
Unwanted extra space
Here is my code (I set the text before this point):
self.infoDescription.numberOfLines = 0;
[self.infoDescription sizeToFit];
self.infoDescription.frame = CGRectMake(20, self.infoAdultSize.frame.size.height+self.infoAdultSize.frame.origin.y+10, self.infoView.frame.size.width-40, self.infoDescription.frame.size.height);
Please help :( I just want the height of the UILabel to fit the text exactly.
First set the frame and then make size to fit of label.
**self.infoDescription.frame = CGRectMake(20, self.infoAdultSize.frame.size.height+self.infoAdultSize.frame.origin.y+10, self.infoView.frame.size.width-40, self.infoDescription.frame.size.height);
[self.infoDescription sizeToFit];**
Try this:
CGSize maximumSize = CGSizeMake(300, 9999);
NSString *myString = #"This is a long string which wraps";
UIFont *myFont = [UIFont fontWithName:#"Helvetica" size:14];
CGSize myStringSize = [myString sizeWithFont:myFont
constrainedToSize:maximumSize
lineBreakMode:self.myLabel.lineBreakMode];

Please check this answer it works for me and it is exactly what you are looking for.
//Calculate the expected size based on the font and linebreak mode of your label
// FLT_MAX here simply means no constraint in height
CGSize maximumLabelSize = CGSizeMake(296, FLT_MAX);
CGSize expectedLabelSize = [yourString sizeWithFont:yourLabel.font constrainedToSize:maximumLabelSize lineBreakMode:yourLabel.lineBreakMode];
//adjust the label the the new height.
CGRect newFrame = yourLabel.frame;
newFrame.size.height = expectedLabelSize.height;
yourLabel.frame = newFrame;
UITextView add ...more button at the end of visible text like on facebook.
I am sorry if it already mentioned somewhere. Specifically I am interested how to count position of the end of visible text with wrapping words
1 . Check UItextView size base on text and Font:
// return the size for UITextView for both IOS7 and IOS6
-(CGSize) getSizeWithMaxLabelSize:(CGSize) maxLabelSize forTextViewWithText:(NSString *) text
{
CGSize expectedLabelSize;
CGSize maximumLabelSize = maxLabelSize;
if (SYSTEM_VERSION_GREATER_THAN(#"6.2")) {
NSDictionary *stringAttributes = [NSDictionary dictionaryWithObject:[UIFont fontWithName:#"Arial" size:EPCommentViewFontSize] forKey: NSFontAttributeName];
CGRect rect =[text boundingRectWithSize:maximumLabelSize options:NSStringDrawingUsesLineFragmentOrigin attributes:stringAttributes context:nil];
expectedLabelSize = rect.size;
expectedLabelSize.height = ceilf(expectedLabelSize.height);
expectedLabelSize.width = ceilf(expectedLabelSize.width);
} else {
expectedLabelSize = [text sizeWithFont:[UIFont fontWithName:#"Arial" size:EPCommentViewFontSize] constrainedToSize:maximumLabelSize lineBreakMode:NSLineBreakByWordWrapping];
}
return expectedLabelSize;
}
2 . Compare your UITextView height with expectedLabelSize.height to show ViewMore or not
3 . Change UITextView frame.size.height when touched viewMore
CGRect frame = _textView.frame;
frame.size.height = [self getSizeWithMaxLabelSize:CGSizeMake(_textView.frame.size.height, NSIntegerMax) forTextViewWithText:_textView.text].height;
_textView.frame = frame;
I am developing an app which required to display UILabel into UITableviewCell. I also need to resize UILabel as per text size.
I am using following code for get contentsize of text size.
CGRect rect = [as boundingRectWithSize:CGSizeMake(220.0, 2000.0) options:NSStringDrawingUsesLineFragmentOrigin attributes:#{NSFontAttributeName: font} context:nil];
For update frame of UILabel I use following code.
rect.origin.x = cell.lblDescription.frame.origin.x;
rect.origin.y = cell.lblDescription.frame.origin.y;
rect.size.width = cell.lblDescription.frame.size.width;
[cell.lblDescription setFrame:rect];
It set wrong frame.
Please find attached screenshot.
NSString *text = [NSString stringWithFormat:#"%#",[[arr_cart objectAtIndex:indexPath.row] objectForKey:#"name"]];
UIFont *font = [UIFont fontWithName:#"ArialMT" size:12];
CGSize size = [(text ? text : #"") sizeWithFont:font constrainedToSize:CGSizeMake(200, 9999) lineBreakMode:NSLineBreakByWordWrapping];
UILabel *lbl_desc=[[UILabel alloc]init];
lbl_desc.numberOfLines = 0;
lbl_desc.frame=CGRectMake(70,18, size.width, size.height);
lbl_desc.lineBreakMode = NSLineBreakByWordWrapping;
lbl_desc.text = (text ? text : #"");
lbl_desc.font = font;
lbl_desc.backgroundColor=[UIColor clearColor];
lbl_desc.textColor = [UIColor darkTextColor];
[cell.contentView addSubview:lbl_desc];
[lbl_desc release];
You have to check the height of the label in - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath UITableViewDelegate Method.
CGSize maximumLabelSize = CGSizeMake(your_label_width, FLT_MAX);
CGSize expectedLabelSize = [label_text sizeWithFont:[UIFont fontWithName:#"your_font" size:your_font_size] constrainedToSize:maximumLabelSize lineBreakMode:NSLineBreakByWordWrapping];
then set the cell height as expectedLabelSize.height.
also do the same thing in your custom cell.
Use following code
[self setDynamicHeightOfLabel:lblName withLblWidth:97 andFontSize:13];
In above method you just need to pass your UILabel name with specific width and fontSize of label.
-(void) setDynamicHeightOfLabel:(UILabel *) myLabel withLblWidth:(CGFloat) width andFontSize:(int) fontSize
{
CGSize myLabelSize = CGSizeMake(width, FLT_MAX);
CGSize expecteingmyLabelSize = [myLabel.text sizeWithFont:myLabel.font constrainedToSize:myLabelSize lineBreakMode:myLabel.lineBreakMode];
CGRect lblFrame = myLabel.frame;
lblFrame.size.height = expecteingmyLabelSize.height;
myLabel.frame = lblFrame;
int addressLine = myLabel.frame.size.height/fontSize;
myLabel.numberOfLines = addressLine;
}
Using above code you can set dynamic height of UILabel.
In iOS 7 I use new method to calculate the textview height,but it seems that it's not word wrapping, besides,the height is not the height of the text.
self.textview.textContainer.lineBreakMode = NSLineBreakByWordWrapping;
self.textview.showsHorizontalScrollIndicator= NO;
self.textview.showsVerticalScrollIndicator = NO;
// [self.textview sizeThatFits:CGSizeMake(296, 474)];
// [self.textview.text sizeWithFont:[UIFont systemFontOfSize:14] forWidth:296.0 lineBreakMode:NSLineBreakByWordWrapping];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
[paragraphStyle setLineBreakMode:NSLineBreakByWordWrapping];
NSDictionary *attributes = #{ NSFontAttributeName: self.textview.font, NSParagraphStyleAttributeName : paragraphStyle };
//
CGSize size= [self.textview.text boundingRectWithSize:CGSizeMake(CGRectGetWidth(self.textview.frame), MAXFLOAT)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:attributes
context:nil].size;
CGRect frame = self.textview.frame;
frame.size = size;
self.textview.frame= frame;
anyone help?
solved the problem it's because the text has wrong white charter ,that is it replace white character with other character.
Try this:
CGSize maximumLabelSize = CGSizeMake(295,99999);
CGSize expectedLabelSize = [self.textview. sizeWithFont:self.textview..font constrainedToSize:maximumLabelSize lineBreakMode:self.textview.lineBreakMode];
//adjust the label the the new height.
CGRect newFrame = self.textview.frame;
newFrame.size.height = expectedLabelSize.height;
self.textview.frame = newFrame;
Check image having your given text : http://screencast.com/t/Yqr6oSOvhN1
I had a similar problem because I had a wrong character space.
For replace I used:
message = [message stringByReplacingOccurrencesOfString:#"\u00A0" withString:#“ "];
I can't get this dynamic label to resize its height according to the content. It logs the correct info but the label is always the same height. Any ideas?
self.descriptionLabel.text = string;
self.descriptionLabel.adjustsFontSizeToFitWidth = YES;
self.descriptionLabel.numberOfLines=0;
CGSize maximumLabelSize = CGSizeMake(296,9999);
CGSize expectedLabelSize = [string sizeWithFont:[UIFont fontWithName:#"Helvetica" size:14] constrainedToSize:maximumLabelSize lineBreakMode:NSLineBreakByWordWrapping];
//adjust the label the the new height.
CGRect newFrame = self.descriptionLabel.frame;
newFrame.size.height = expectedLabelSize.height;
NSLog(#"the height %f", newFrame.size.height);
self.descriptionLabel.frame = newFrame;
CGSize constraintSize = CGSizeMake(requiredWidth, MAXFLOAT);
CGSize labelSize = [requiredLableText sizeWithFont:requiredFont constrainedToSize:constraintSize lineBreakMode:UILineBreakModeWordWrap];
returned size will give u the dynamic height of the UILabel
