I am trying to set the font of the label as per follow but it gives me zero CGSize for that.
UIFont *abbrFont = [UIFont fontWithName:#"Helvetica Cyrillic Bold_5" size:50]; //Helvetica Cyrillic Bold_5 added Custom Font
CGSize abbrSizeOfString = [_addbrTitle sizeWithFont:abbrFont];//_addbrTitle is a NSString
NSLog(#"%f %f",abbrSizeOfString.width,abbrSizeOfString.height); //Everytime Prints (0.000,0.000)
Help me to solve this.
Thank you.
Try this,
UIFont *abbrFont = [UIFont fontWithName:#"Helvetica" size:50]; //Helvetica Cyrillic Bold_5 added Custom Font
CGSize abbrSizeOfString = [_addbrTitle.text sizeWithFont:abbrFont];//_addbrTitle is a Label
NSLog(#"%f %f",abbrSizeOfString.width,abbrSizeOfString.height); //E
You can use this line to set the size for label..
[label setFont:[UIFont fontWithName:#"Helvetica" size:20.0]];
UILabel *_addbrTitle = [[UILabel alloc] init];
[_addbrTitle setText:#"Hello"];
UIFont *abbrFont = [UIFont fontWithName:#"Helvetica" size:50]; //Helvetica Cyrillic Bold_5 added Custom Font
[_addbrTitle setFont:abbrFont];
CGSize abbrSizeOfString = [_addbrTitle.text sizeWithFont:abbrFont];//_addbrTitle is a Label
NSLog(#"%f %f",abbrSizeOfString.width,abbrSizeOfString.height); //Everytime Prints (0.000,0.000)
Font name you have entered in the code does not exists in system. So its printing (0,0) every time. Enter a font name which exists in system it will print the size.
change your font name to some other built in font name then try
like this
yourLabel.font=[UIFont fontWithName:#"Helvetica" size:16];
Your font name is not current follow this IOS supporting fonts list and Font name
http://iosfonts.com/
NSURL *fontURL = [NSURL URLWithString:[[NSBundle mainBundle]pathForResource:#"your_font_name" ofType:#"TTF"]];
for example:
NSURL *fontURL2 = [NSURL URLWithString:[[NSBundle mainBundle]pathForResource:#"segoe_semi_bold" ofType:#"TTF"]];
NSURL *fontURL2 = [NSURL URLWithString:[[NSBundle mainBundle]pathForResource:#"segoe_semi_bold" ofType:#"TTF"]];
now make add url to array
NSArray *arrFont =[[NSArray alloc]initWithObjects:fontURL1,fontURL2, nil];
int result =CTFontManagerRegisterFontsForURLs((CFArrayRef)arrFont, kCTFontManagerScopeUser, nil);
if(result)
{
NSLog("Font Install successfully");
}
now you can get font
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];

i hope you get some idea from this post...
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)];
This code works well to make a url appear in a UITextview
UITextView * descriptionTextView = [[UITextView alloc] initWithFrame:CGRectMake(10, 50, 300, 300)];
descriptionTextView.textColor = [UIColor whiteColor];
descriptionTextView.dataDetectorTypes = UIDataDetectorTypeLink;
descriptionTextView.font = [UIFont fontWithName:#"Helvetica" size:16];
descriptionTextView.backgroundColor = [UIColor clearColor];
descriptionTextView.text = #"Click to go to the google website, http://www.google.com ";
descriptionTextView.autocorrectionType = UITextAutocorrectionTypeNo;
descriptionTextView.keyboardType = UIKeyboardTypeDefault;
descriptionTextView.returnKeyType = UIReturnKeyDone;
descriptionTextView.editable = NO;
descriptionTextView.tag = 1;
[self.view addSubview:descriptionTextView];
The problem is that I the whole url I write appears, http://www.google.com
Is there a way I can use just a single word to contain the link? So the user can only see 'Goggle' written in blue and when they click that work it opens safari.
Many Thanks,
-Code
you can do it use a UIWebview
use
- (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL;
and code the whole message then wrap the link to
[webView.loadHTMLString:#"Google" baseURL:nil];
I know this is super old thread. UITextView supports rich text/HTML. You should create NSAttributedString and assign it to attributedText property to manipulate with non plain text content. Like so:
NSString *htmlString = #"<your HTML code>";
textView.attributedText = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding]
options:#{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
NSCharacterEncodingDocumentAttribute: #(NSUTF8StringEncoding)}
documentAttributes:nil
error:nil];
