UILabel *label = [[UILabel alloc] init];
label.text = #"Hello";
[label sizeToFit];
CGSize size = label.frame.size;
Usually we get the size of the label in this way, but text in the UILabel does not fill all space in it, there's always some margin around the text. That makes drawing label difficult to be exactly the same as visual draft. Anyone could help ？
for example: If you want to put an icon at the bottom of some text, let the margin between them be, for example 50px, and you write icon.frame = CGRectMake(10,textLabel.frame.size.height + textLabel.frame.origin.y + 50, 100, 100); but since the text can't fill all space in UILabel, so the margin in this way should be a bit larger than it should be. So I want to figure out a better way, thanks.
try with this bellow method which returns dynamic height of UILable with its text content... we this method you can set frame of UILable with its text content...
-(float) calculateHeightOfTextFromWidth:(NSString*) text: (UIFont*)withFont: (float)width :(UILineBreakMode)lineBreakMode
{
[text retain];
[withFont retain];
CGSize suggestedSize = [text sizeWithFont:withFont constrainedToSize:CGSizeMake(width, FLT_MAX) lineBreakMode:lineBreakMode];
[text release];
[withFont release];
return suggestedSize.height;
}
and use it like bellow...
UILabel *lblAddress = [[UILabel alloc]init];
[lblAddress setFrame:CGRectMake(110, 31, 200, 50)];
lblAddress.text = #"your Text ";
lblAddress.lineBreakMode = UILineBreakModeWordWrap;
lblAddress.numberOfLines = 0;
lblAddress.font = [UIFont fontWithName:#"Helvetica" size:12];
lblAddress.frame = CGRectMake(lblAddress.frame.origin.x, lblAddress.frame.origin.y,
200,[self calculateHeightOfTextFromWidth:lblAddress.text :lblAddress.font :200 :UILineBreakModeWordWrap] );
lblAddress.textColor = [UIColor darkGrayColor];
[self.view addSubview:lblAddress];
See My Blog..
i hope you get some idea from this post...
I created a UILabel dynamically and i will update the data in to that dynamically.
Am getting output with many number of lines and it is fine
my problem is word break in middle to the next line although i use line break mode word wrap
Help me out of this am googling it from 5hours.
The data passed to that UILabel is orthogonist,endonist,psychologist,cardioligist
CGSize constraint8 = CGSizeMake(190, 2000.0f);
CGSize size8=[temp sizeWithFont:[UIFont fontWithName:#"Helvetica-Bold" size:14] constrainedToSize:constraint8 lineBreakMode:UILineBreakModeWordWrap];
specialities1 =[[UILabel alloc]init];
[specialities1 setFrame:CGRectMake(124,218,190, size8.height)];
specialities1.textAlignment=UITextAlignmentLeft;
specialities1.backgroundColor=[UIColor clearColor];
specialities1.numberOfLines=0;
specialities1.lineBreakMode=UILineBreakModeClip;
specialities1.font=[UIFont fontWithName:#"Helvetica-Bold" size:14];
specialities1.text=[NSString stringWithFormat:#"%# ",temp ];
[specialities1 sizeToFit];
[testscroll addSubview:specialities1];
Change:
specialities1.lineBreakMode=UILineBreakModeClip;
to :
specialities1.lineBreakMode= UILineBreakModeWordWrap;
Change both this line in your code.
According to your code above you are setting 0 lines in your label. So change it to,
specialities1.numberOfLines=size8.height/12;//(=1000, or whatever according to your requirement)
specialities1.lineBreakMode= UILineBreakModeWordWrap;

Get size
NSString *text = [dicOtherInfo objectForKey:#"msg"];
CGSize constraint = CGSizeMake(200, 1000.0f);
CGSize size = [text sizeWithFont: [UIFont fontWithName:#"Verdana" size:12] constrainedToSize:constraint lineBreakMode:UILineBreakModeWordWrap];
Set Size
UILabel *lblMsg=[[UILabel alloc] initWithFrame:CGRectMake(5,15, size.width, size.height)];
[lblMsg setLineBreakMode:UILineBreakModeWordWrap];
lblMsg.text = text;
lblMsg.numberOfLines = (size.height/16);
lblMsg.textAlignment=UITextAlignmentLeft;
lblMsg.backgroundColor=[UIColor clearColor];
lblMsg.textColor=[UIColor redColor];
[lblMsg setFont:[UIFont fontWithName:#"Verdana" size:12]];
Try my below method:
-(float) calculateHeightOfTextFromWidth:(NSString*) text: (UIFont*)withFont: (float)width :(UILineBreakMode)lineBreakMode
{
[text retain];
[withFont retain];
CGSize suggestedSize = [text sizeWithFont:withFont constrainedToSize:CGSizeMake(width, FLT_MAX) lineBreakMode:lineBreakMode];
[text release];
[withFont release];
return suggestedSize.height;
}
and use it like below:
UILabel *lblAddress = [[UILabel alloc]init];
[lblAddress setFrame:CGRectMake(110, 31, 200, 50)];
lblAddress.text = #"your Text ";
lblAddress.lineBreakMode = UILineBreakModeWordWrap;
lblAddress.numberOfLines = 0;
lblAddress.font = [UIFont fontWithName:#"Helvetica" size:12];
lblAddress.frame = CGRectMake(lblAddress.frame.origin.x, lblAddress.frame.origin.y,
200,[self calculateHeightOfTextFromWidth:lblAddress.text :lblAddress.font :200 :UILineBreakModeWordWrap] );
lblAddress.textColor = [UIColor darkGrayColor];
[self.view addSubview:lblAddress];
I am trying to get a CGSize for an NSString but I am having issues. Here is the code I am using:
CGFloat actualMessageFontSize;
CGSize messageSize =
[message sizeWithFont:[UIFont fontWithName:#"Helvetica-Bold"
size:14.0f]
minFontSize:14.0f
actualFontSize:&actualMessageFontSize
forWidth:(alertViewWidth - textIndent)
lineBreakMode:NSLineBreakByWordWrapping];
I NSLog the CGSize after this code and the height doesn't change, even if I put a massive NSString into it. Do you know why this might happen and or what I should try instead?
Thanks.
use this method and
-(float) calculateHeightOfTextFromWidth:(NSString*) text: (UIFont*)withFont: (float)width :(UILineBreakMode)lineBreakMode
{
[text retain];
[withFont retain];
CGSize suggestedSize = [text sizeWithFont:withFont constrainedToSize:CGSizeMake(width, FLT_MAX) lineBreakMode:lineBreakMode];
[text release];
[withFont release];
return suggestedSize.height;
}
and use it like bellow... i use this for UILable see the code..
UILabel *lblAddress = [[UILabel alloc]init];
[lblAddress setFrame:CGRectMake(110, 31, 200, 31)];
lblAddress.text = #"ABDKFNKG KKGK jfnjgdf gdklfg fldgmfkgml f";
lblAddress.lineBreakMode = UILineBreakModeWordWrap;
lblAddress.numberOfLines = 0;///write this line for multiple line and set 0 or anything lese
lblAddress.font = [UIFont fontWithName:#"Helvetica" size:12];
lblAddress.frame = CGRectMake(lblAddress.frame.origin.x, lblAddress.frame.origin.y,
200,[self calculateHeightOfTextFromWidth:lblAddress.text :lblAddress.font :200 :UILineBreakModeWordWrap] );
lblAddress.textColor = [UIColor darkGrayColor];
[self.view addSubview:lblAddress];
You have change frame of UILabel or UITextView which of them might be using to change accordingly.
CGFloat actualMessageFontSize = 12.0;
CGSize messageSize = [message sizeWithFont:[UIFont fontWithName:#"Helvetica-Bold" size:14.0f] minFontSize
//set frame accordingly
yourLabel.frame = CGReactMake(yourLabel.frame.origin.x,yourLabel.frame.origin.y,messageSize.width,messageSize.wiheight,);
I have a very long string which is something like that below...
[[sqrt(221)-10,-sqrt(221)-10],[11,11]],[[rootof([[474368400,237184200,-125944810200,258530778000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)+rootof([[409681800,9099248400,-99876110400,-1875803589000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*3,rootof([[-3439170900,-50638826700,864180632700,9670592794500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)+rootof([[1477010700,22974524100,-369910322100,-4442729593500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*3],[rootof([[474368400,237184200,-125944810200,258530778000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*2+rootof([[409681800,9099248400,-99876110400,-1875803589000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*4,rootof([[-3439170900,-50638826700,864180632700,9670592794500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*2+rootof([[1477010700,22974524100,-369910322100,-4442729593500],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)*4]],[sqrt(sqrt(221)+15),sqrt(-sqrt(221)+15)]
How can i display the whole thing in a UILabel with more than one lines (0)?
Also, although there are no linebreaks ("\n") in the string, the result is displayed like below....
[[sqrt(221)-10,-sqrt(221)- 10],[11,11]],[[rootof([[474368400,2 37184200,- 125944810200,258530778000],[1, 0,- 472,884,42215]])/(sqrt(221)*78270
Any help?
PS I could upload an image but i am not allowed beacause i am a new user...
textLabel.lineBreakMode = UILineBreakModeWordWrap;
textLabel.numberOfLines = 0;
set the UILabel as a multiline
MyLbl.numberOfLines = xxx;
if you have not enough space for set the UIlabel then also set the textView As an not editable property:
Mytxt = [[UITextView alloc]initWithFrame:CGRectMake(xx.0, x.0, xx.0,xx.0)];
Mytxt.transform = transform;
Mytxt.adjustsFontSizeToFitWidth = YES;
Mytxt.textColor = [UIColor blackColor];
Mytxt.autoresizingMask=UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[Mytxt setFont:[UIFont fontWithName:#"Arial" size:xx.0]];
Mytxt.backgroundColor = [UIColor clearColor];
Mytxt.delegate = self;
Mytxt.userInteractionEnabled=YES;
Mytxt.editable=NO;
i hope you get the answer.
You can use UITextView with auto size with non editable mode instead of UILabel (or)
CGSize labelSize = yourString sizeWithFont:cellFont
constrainedToSize:CGSizeMake(190.0f, MAXFLOAT); lineBreakMode:UILineBreakModeWordWrap];
This labelsize will dynamically define the label height you can assign to your label
try this code
NSString *yourString = #"[[sqrt(221)-10,-sqrt(221)-10],[11,11]],[[rootof([[474368400,237184200,-125944810200,258530778000],[1,0,-472,884,42215]])/(sqrt(221)*782707860000)+rootof([[409681800,9099248400,-99876110400,-1875803589000],[1,0,-472,884,42215]])";
UILabel *lblNameDesc=[[UILabel alloc] initWithFrame:CGRectMake(55, 10, 250, 21)];
[lblNameDesc setNumberOfLines:0];
lblNameDesc.text=yourString;
[lblNameDesc setBackgroundColor:[UIColor clearColor]];
[lblNameDesc setTextColor:[UIColor colorWithRed:64.0/255.0 green:64.0/255.0 blue:64.0/255.0 alpha:1.0f]];
[self.view addSubview:lblNameDesc];
// [lblNameDesc release];
[lblNameDesc sizeToFit];
supoose your string is. make your fond and width what ever you want:-
NSString longString = #"dsjkghsdkjnfgvsdjgsl,v.........................";
CGSize maximumLabelSize = CGSizeMake(200,MAXFLOAT);
CGSize expectedLabelSize = [longString sizeWithFont:[UIFont fontWithName:#"Aial-BoldMT" size:15.0] constrainedToSize:maximumLabelSize
lineBreakMode:UILineBreakModeWordWrap];
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(50, 100, 200, expectedLabelSize.height)];
myLabel.lineBreakMode = UILineBreakModeWordWrap;
myLabel.numberOfLines = 0;
myLabel.text = longString ;
may this will help you
Try This...
textLabel.lineBreakMode = YES;
textLabel.numberOfLines = 10; // or many that you need...
You want UILineBreakModeCharacterWrap if you want your text to be evenly distributed along several lines (so it doesn't try to break at work boundaries).
I set up a UITextView that acts strange. If I set it's content to a long text it breaks it correctly at the boundaries however if the content is single lined it automatically breaks it before the last word even if it fits in one line. It created sort of a minimum of lines.
I wasn't able to find this issue posted on the web so I had to ask.
Here's the set up of the UITextView
Message * displayedMessage = [messages objectAtIndex:indexPath.row];
UIFont * messageFont = [UIFont fontWithName:#"Helvetica" size:13];
CGSize messageSize = [displayedMessage.content sizeWithFont:messageFont constrainedToSize:CGSizeMake(240.f, 3000.f) lineBreakMode:UILineBreakModeWordWrap];
UITextView * messageTextView = [[UITextView alloc] initWithFrame:CGRectMake(46.f, 0.f, messageSize.width, messageSize.height + 25)];
messageTextView.backgroundColor = [UIColor clearColor];
messageTextView.font = messageFont;
messageTextView.editable = NO;
messageTextView.scrollEnabled = NO;
messageTextView.contentInset = UIEdgeInsetsZero;
messageTextView.textColor = [UIColor blackColor];
[messageTextView setDataDetectorTypes:UIDataDetectorTypeAll];
messageTextView.text = displayedMessage.content;
[cell addSubview:messageTextView];
I managed to solve it eventually i just had to define the textview like this, with a fixed width:
> UITextView * messageTextView = [[UITextView alloc]
> initWithFrame:CGRectMake(46.0f, 0.0f, 240.0f, messageSize.height +
> 25)];
