Here is the text present in my UILable...
"This list isn’t actually based on a straight popularity count; simply tallying the most-read verses results in a top 100 list that consists almost entirely of John 3:16 and verses from 1 Corinthians 13, Genesis 1, Romans 8, and Psalm 23. Our list instead considers instances in which BibleGateway.com users looked at three or fewer verses at one time."
How do i get the final line of text..ie.,"at three or fewer verses at one time." from my uilable.
Any solution is greatly appreciated.
I can give one idea . May this will help you.
UILabel *myLabel = [[UILabel alloc] initWithFrame:CGRectMake(50,50,200,350)];
myLabel.numberOfLines = 0;
myLabel.lineBreakMode = UILineBreakModeWordWrap;
myLabel.text = #"This is some text in a UILabel which is long enough to wrap around the lines in said UILabel. This is a test, this is only a test.";
[self.view addSubview:myLabel];
CGSize labelSize = [myLabel.text sizeWithFont:myLabel.font
constrainedToSize:myLabel.frame.size
lineBreakMode:UILineBreakModeWordWrap];
CGFloat labelHeight = labelSize.height;
NSLog(#"labelHeight = %f", labelHeight);
[myLabel release];
with above you can get height of label, then you can get the # of lines by dividing the height with some appropriate number which depends on the font size.
1) After this Get NSAttributedString from your UILabel.
2) From NSAttributedString you can get "\n" characters.
3) get last "\n" and extract value from this index to last index.

I am trying to create a custom cell which consists a few UILabels.
The first label might take one or more rows, so I need to resize the label according to the number of lines (after setting the number of lines to 0, so multi-line will be enabled).
I have tried setting sizeToFit(), but it changed the alignment and width of my label.
I found this answer
but I don't know how to convert it to C#.
Can anyone point me to an example? (I already tried Googling it off-course)
This is the method from the link:
// UILabel *myLabel;
CGSize labelSize = [myLabel.text sizeWithFont:myLabel.font
constrainedToSize:myLabel.frame.size
lineBreakMode:UILineBreakModeWordWrap];
CGFloat labelHeight = labelSize.height;
int lines = [myLabel.text sizeWithFont:myLabel.font
constrainedToSize:myLabel.frame.size
lineBreakMode:UILineBreakModeWordWrap].height/16;
// '16' is font size
var size = myLabel.StringSize("Some really long string", myLabel.Font, myLabel.Frame.Size, UILineBreakMode.CharacterWrap);
var lines = size.Height / myLabel.Font.CapHeight;
I am trying to adjust the size of the text in my UITextView so it fits. I have the following code:
NSString *storyTitle = [newsfeedToSubject.properties valueForKey:#"title"];
int currentFontSize = 18;
UIFont *currentFont = [UIFont fontWithName:kProximaNovaBold size:currentFontSize];
CGSize storyTitleSize = [storyTitle sizeWithFont:currentFont constrainedToSize:self.newsfeedStoryTitle_.frameSize lineBreakMode:UILineBreakModeWordWrap];
while (storyTitleSize.height >= self.newsfeedStoryTitle_.frameHeight){
currentFontSize--;
currentFont = [UIFont fontWithName:kProximaNovaBold size:currentFontSize];
storyTitleSize = [storyTitle sizeWithFont:currentFont constrainedToSize:self.newsfeedStoryTitle_.frameSize lineBreakMode:UILineBreakModeWordWrap];
}
[self.newsfeedStoryTitle_ setFont:currentFont];
[self.newsfeedStoryTitle_ setText:storyTitle];
[self.newsfeedStoryTitle_ setBackgroundColor:[UIColor redColor]];
However, here's what I am getting:
I tried with different line break mode and also set the autoresize to none, but it didn't help. Any idea?
Your while loop will not do what you want because you are using
storyTitleSize.height
to determine the size of the frame, which will not take into account the wrap around effect of the text. One suggestion would be to truncate the string and only display a certain amount of characters of the title. Otherwise, you will need to calculate how many line breaks you will have, based on the width of the frame and the length of the string, and use
while(storyTitleSize.height * numLineBreaks >= self.newsFeedStoryTitle_.frameHeight)
{
...
}
Hope that helps.
You can also dynamically resize your frame (UITextView) as in this thread
try these code
while (self.textView.contentSize.height >= frameHeight){
currentFontSize--;
currentFont = [UIFont fontWithName:kProximaNovaBold size:currentFontSize];
[self.textView setFont:currentFont];
self.textView.text = #"your string";
}
My UILabel can do a line break according to the current \n . But if the line itself is too long, it won't be able to automatically do a line break. Can I do more configurations to my UILabel to achieve that?
And I've already used:
aLabel.lineBreakMode = UILineBreakModeWordWrap;
aLabel.numberOfLines = 0;
[aLabel setFont:[UIFont fontWithName:#"MarkerFelt-Wide" size:24]];
aLabel.textAlignment = UITextAlignmentCenter;
CGRect labelFrame = aLabel.bounds;
labelFrame.size = [words sizeWithFont:aLabel.font constrainedToSize:CGSizeMake(LABEL_WIDTH, 100000) lineBreakMode:aLabel.lineBreakMode];
aLabel.frame = CGRectMake(0, 0, aLabel.frame.size.width-10, labelFrame.size.height);
words is a NSString
Set Number of line as you want to set.
aLabel.numberOfLines = 2;
if you are having text in a paragraph and want to place it in a lable with differ lines no need to use UILineBreakModeWordWrap.. simply write one line code as in how many lines you want to place the text as
labobj.numberOfLines = 90;
I'm trying to create a simple custom UIView wich contain a string drawn with a single font, but where the first character is slightly larger.
I thought this would be easily implemented with two UILabel:s placed next to eachother.
I use NSString sizeWithFont to measure my string to be able to lay it out correctly.
But I noticed that the font baseline in the returned rectangle varies with +/- 1 pixel depending on the font size I set.
Here is my code:
NSString* ctxt = [text substringToIndex:1];
NSString* ttxt = [text substringFromIndex:1];
CGSize sz = [ctxt sizeWithFont: cfont ];
clbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, sz.width, sz.height)];
clbl.text = ctxt;
clbl.font = cfont;
clbl.backgroundColor = [UIColor clearColor];
[contentView addSubview:clbl];
CGSize sz2 = [ttxt sizeWithFont: tfont];
tlbl = [[UILabel alloc] initWithFrame:CGRectMake(sz.width, (sz.height - sz2.height), sz2.width, sz2.height)];
tlbl.text = ttxt;
tlbl.font = tfont;
tlbl.backgroundColor = [UIColor clearColor];
[contentView addSubview:tlbl];
If I use 12.0 and 14.0 as sizes, it works fine.
But if I instead use 13.0 and 15.0, then the first character is 1 pixel too high.
Is this a known problem?
Any suggestions how to work around it?
Creating a UIWebView with a CSS and HTML page seems way overkill for this. and more work to handle dynamic strings. Is that what I'm expected to do?
Found the answer...
Ofcourse, I also have to check the descender value on the font, and compensate for that in the layout.
New rect for the second label is:
CGRectMake(sz.width, (sz.height - sz2.height) + floor(cfont.descender - tfont.descender), sz2.width, sz2.height)
floor() is to make sure it snaps to pixel position, or the font will look blurry
I know there is this one:
sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode:
But since the CGSize always has the same height and doesn't adjust to any shrinked text or whatsoever, the CGSize is not telling how heigh the text is.
Example: Make a UILabel with 320 x 55 points and put a loooooooooooooong text in there. Let the label shrink the text down. Surprise: CGSize.height remains the same height even if the text is so tiny that you need a microscope.
Ok so after banging my head against my macbook pro which is half way broken now, the only think that can help is that nasty actualFontSize. But the font size is in pica I think, it's not really what you get on the screen, isn't it?
When that font size is 10, is my text really 10 points heigh at maximum? Once in a while I tried exactly that, and as soon as the text had a y or some character that extends to below (like that tail of an y does), it is out of bounds and the whole text is bigger than 10 points.
So how would you calculate the real text height for a single line uilabel without getting a long beard and some hospital experience?
Try this code:
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];
from my answer here
It uses a different method, and sets up a very high CGSize at the start (which is then shrunk to fit the string)
Important: As of iOS 7.0 the following method is deprecated.
sizeWithFont:minFontSize:actualFontSize:forWidth:lineBreakMode:
Use the below code instead
CGRect frame = [cellText boundingRectWithSize:CGSizeMake(568,320) options:NSStringDrawingUsesLineFragmentOrigin attributes:#{NSFontAttributeName:[UIFont systemFontOfSize:32.0f]} context:nil];
float height = frame.size.height;
Sounds like after you get the actual font size from that function call, you need to call again with that new size:
NSString* yourString = #"SomeString";
float actualSize;
[yourString sizeWithFont:yourFont
minFontSize:minSize
actualFontSize:&actualSize
forWidth:rectWidth
lineBreakMode:breakMode];
CGSize size = [yourString sizeWithFont:[UIFont fontWithName:fontName size:actualSize]];
Also have you set label.numberOfLines = 0; ?
After running this code frame.size will have the height and width of your nsstring exactly..
NSString *text = #"This is my Mac";
textFont = [NSFont fontWithName:#"HelveticaNeue-Medium" size: 80.f];
textColor = [NSColor yellowColor];
NSDictionary *attribs = #{ NSForegroundColorAttributeName:textColor,
NSFontAttributeName: textFont };
CGRect frame = [text boundingRectWithSize:CGSizeMake(0,0) options:NSStringDrawingUsesLineFragmentOrigin|NSStringDrawingUsesDeviceMetrics attributes:attribs context:nil];
