Is it possible to change both width and height of the textview with respect to content. Here, the height of the text only varies when user enters an new line character.
How to do pinch zoom on textview, such that font doesn't look blur. It needs to be work on from iOS5.
Try this it has worked for me. viewNote is my textView object. it is for height
CGRect frame = viewNote.frame;
NSLog(#"Text Size height : %f",frame.size.height);
CGSize textViewSize;
if (isIPhone) {
textViewSize = [viewNote.text sizeWithFont:[UIFont fontWithName:#"Helvetica" size:20]
constrainedToSize:CGSizeMake(309, 10000)
lineBreakMode:UILineBreakModeTailTruncation];
}else{
textViewSize = [viewNote.text sizeWithFont:[UIFont fontWithName:#"Helvetica" size:30]
constrainedToSize:CGSizeMake(768, 10000)
lineBreakMode:UILineBreakModeTailTruncation];
}
frame.size.height = textViewSize.height;
viewNote.frame = frame;
NSLog(#"Text Size height : %f",frame.size.height);

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 have a UISlider that changes the font size of a UITextView. Before changing the font size, I would like to check if the height of my UITextView will be inferior to the height of its view container. The problem is that sizeToFit and sizeWithAttribute are returning different heights for the same font size.
To do that i'm trying to get the height of my UITextView with a custom fontSize, but i cannot figure out a way to do so, and don't understand why I don't get the same height when I do:
self.photoDescription.text = #"Test"
self.photoDescription.font = [self.photoDescription.font fontWithSize:18];
[self.photoDescription sizeToFit];
NSLog(#"real height %f", self.photoDescription.frame.size.height);
//getting : 37.5
and:
NSLog(#"calculated height %f", [self.photoDescription.text sizeWithAttributes:#{NSFontAttributeName:[self.photoDescription.font fontWithSize:18]}].height);
//getting: 20.97
same thing for:
CGRect textRect = [self.photoDescription.text boundingRectWithSize:CGSizeMake(320, 300)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName:[self.photoDescription.font fontWithSize:18]}
context:nil];
CGSize size = textRect.size;
NSLog(#"height %f", size.height);
// getting : 20.97
Any thoughts on this?
I finally found an answer to my question with Jordan Montel Solution:
iOS7 UITextView contentsize.height alternative
I used his function to get the width :
- (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;
}
CGFloat constrainedSize = 500.0f;
UIFont * myFont = [UIFont fontWithName:#"Arial" size:19]; //or any other font that matches what you will use in the UILabel
CGSize textSize = [myText sizeWithFont: myFont
constrainedToSize:CGSizeMake(constrainedSize, CGFLOAT_MAX)
lineBreakMode:NSLineBreakByWordWrapping];
lblDescription=[[UILabel alloc]initWithFrame:CGRectMake(10,y, 300,textSize.height)];
i have tried this code for manage the dynamic text. but if the data comes larger it will not display the whole text.
You constrain the size to width = 500pt, but your textfield is only 300pt wide.
Edit:
It seems, I wasn't clear. If you calculate the height of the label with sizeWithFont and give as constraint a width of 500pt (constrainedSize) and use the calculated height then on a label with only 300pt width, the calculated height is not correct.
This is how it works for me:
CGFloat constrainedSize = 300.0f;
UIFont * myFont = [UIFont fontWithName:#"Arial" size:19]; //or any other font that matches what you will use in the UILabel
CGSize textSize = [myText sizeWithFont: myFont
constrainedToSize:CGSizeMake(constrainedSize, CGFLOAT_MAX)
lineBreakMode:NSLineBreakByWordWrapping];
UILabel* lblDescription=[[UILabel alloc]initWithFrame:CGRectMake(10.0, 10.0, constrainedSize, textSize.height)];
lblDescription.lineBreakMode = NSLineBreakByWordWrapping;
lblDescription.numberOfLines = 0;
lblDescription.font = myFont;
lblDescription.text = myText;
Again: use the same attributes for the label (font, size, lineBreakMode) as you use for the calculation, otherwise it won't fit.
That's because you are alloc and initing the UILabel, and never reset it's frame for bigger size text.
Simply set the frame of the UILabel after a text size change.
This line sets the size of the label, to textSize.height and it doesn't change.
lblDescription=[[UILabel alloc]initWithFrame:CGRectMake(10,y, 300,textSize.height)];
You can call setFrame to programmatically change this.
To display a larger text/Multiline text you should use UITextView instead. It is designed to handle this issue.
hi here is code to set dynamic text in label
CGSize maximumLabelSize = CGSizeMake(300,9999);
CGSize expectedLabelSize = [label.text sizeWithFont:label.font
constrainedToSize:maximumLabelSize
lineBreakMode:label.lineBreakMode];
CGRect newFrame = label.frame;
newFrame.size.height = expectedLabelSize.height;
label.frame = newFrame;
i hope this is helping to you..
I am getting JSON response from server and set that contents to UILabel and sometimes the text will be one line and sometimes the text will be 10 lines.So i display this UILabel inside the UIScrollView. But i got the empty space in UILabel
This is my screenshots..
Currently i am using storyboard and auto layout
So i want to avoid these empty space in UILabel. Please give me suggestions for this alignment issues.??
Code for changing UILabel height but this is not working for me
CGRect textRect = [strDetailsFinal boundingRectWithSize:CGSizeMake(296, FLT_MAX)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:#{NSFontAttributeName: labDetails.font}
context:nil];
CGSize size = textRect.size;
CGRect newFrame = labDetails.frame;
newFrame.size.height = size.height;
labDetails.frame = CGRectMake(160, 200, 300, newFrame.size.height);
May this help you
NSDictionary *attributesDic= [NSDictionary dictionaryWithObjectsAndKeys:
[UIFont fontWithName:#"FontName" size:15], NSFontAttributeName,nil];
CGRect frame = [label.text boundingRectWithSize:CGSizeMake(263, 2000.0)
options:NSStringDrawingUsesLineFragmentOrigin attributes:attributesDic context:nil];
CGSize size = frame.size;
and its possible answer Dynamically resize label in iOS 7 or you can try this https://gist.github.com/danielphillips/1005520
Use [labDetails sizeToFit]. If you have size constraints then use [sizeThatFits:CGSizeMake(WidthConstraint, HeightConstraint)] then use the result of that to set your label frame.
why don't you use UIButton instead of UILabel. UIButton has property to align the text vertically, while UILabel doesn't.
Use UIButton with userInteractionEnabled = NO. Check my this reply here: Vertically align UILabel
Remember one thumb rule - You should not set frame when using autolayout - You are going against Autolayout basic concept - Instead try to autolayout constraints programatically in your case
-(void)awakeFromNib{
[super awakeFromNib];
for(NSLayoutConstraint *cellConstraint in self.constraints){
[self removeConstraint:cellConstraint];
id firstItem = cellConstraint.firstItem == self ? self.contentView : cellConstraint.firstItem;
id seccondItem = cellConstraint.secondItem == self ? self.contentView : cellConstraint.secondItem;
NSLayoutConstraint* contentViewConstraint =
[NSLayoutConstraint constraintWithItem:firstItem
attribute:cellConstraint.firstAttribute
relatedBy:cellConstraint.relation
toItem:seccondItem
attribute:cellConstraint.secondAttribute
multiplier:cellConstraint.multiplier
constant:cellConstraint.constant];
[self.contentView addConstraint:contentViewConstraint];
}
}
You have taken a fix size UILable rather you have to use a dynamic size UILable.
Before that you need to calculate the size of text/string
#define FONT_SIZE 15.0f
#define LABEL_CONTENT_WIDTH 320.0f
#define LABEL_CONTENT_MARGIN 10.0f
NSString *text = #"YOUR TEXT HERE";
CGSize constraint = CGSizeMake(LABEL_CONTENT_WIDTH - (LABEL_CONTENT_MARGIN * 2), 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:FONT_SIZE] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
CGFloat height = MAX(size.height, 44.0f);
after calculating the size, apply them to your label like below
[labDetails setFrame:CGRectMake(labDetails.frame.origin.x, labDetails.frame.origin.y, labDetails.frame.size.width, MAX(height, 44.0f))];
And If you are using autolayout option then please check here: Link
Use Upper label frame's origin and size, and based on that set your detail labels frame, Use sizeToFit property of label.
Suppose 582,618 is your title label,
Like,
labDetails.frame=CGRectMake(5, title.frame.origin.x+title.frame.size.height+5, 300, 100);
[labDetails sizeToFit];
