I want to restrict the width of textLabel of UITabelViewCell as it contains a image on its right side.
I don't want to use UILabel or subclass UITabelViewCell.
Try using the accessoryView property for the image on the right. This should prevent the label from getting too wide and truncating the text.
[cell setAccessoryView:<your image view>];
cell.textLabel.numberOfLines = 3; // set the numberOfLines
cell.textLabel.lineBreakMode = UILineBreakModeTailTruncation;
OR
CGRect aFrame = cell.textLabel.frame;
aFrame.size.width = 100; // for example
cell.textLabel.frame = aFrame;

I am new to iphone.i found UILabel instance methodes very hard for me to implement.how can i use it.how can i customize the appearance of your text of a UIlabel further by subclassing UILabel.Plz i need little help to initiate.Foe example i have a label in my viewController how can i custmize it's text and hoe to subclass
.thanks in advance.
You can use so many properties of a UILabel like:
UILabel *lbl = [[UILabel alloc] initWithFrame:CGRectMake(5, 5, 100, 40)];
lbl.font = [UIFont fontWithName:#"Helvetica" size:12.0]; // For setting font style with size
lbl.textColor = [UIColor whiteColor]; //For setting text color
lbl.backgroundColor = [UIColor clearColor]; // For setting background color
lbl.textAlignment = UITextAlignmentCenter; // For setting the horizontal text alignment
lbl.numberOfLines = 2; // For setting allowed number of lines in a label
lbl.lineBreakMode = UILineBreakModeWordWrap; // For setting line break mode
lbl.text = #"TitleText"; // For setting the text inside the label
Let me know if any thing other than this you want to know!!
The two methods
- (CGRect)textRectForBounds:(CGRect)bounds limitedToNumberOfLines:(NSInteger)numberOfLines
{
return CGRectInset(bounds, MARGIN, MARGIN);
}
- (void)drawTextInRect:(CGRect)rect
{
[super drawTextInRect: CGRectInset(self.bounds, MARGIN, MARGIN)];
}
We are using CGRectInset to create a rectangle that is either larger or smaller than an existing rectangle (bounds).
For Smaller rectangle, use positive values as MARGIN
For Larger rectangle, use positive values as MARGIN
All the best!!!
I have a problem involving UILabel's sizeToFit method:
UILabel *questionLabel = [[UILabel alloc]initWithFrame:CGRectMake(0,0,320,320)];
questionLabel.lineBreakMode = UILineBreakModeWordWrap;
questionLabel.backgroundColor=[UIColor clearColor];
questionLabel.textAlignment=UITextAlignmentLeft;
questionLabel.textColor=[UIColor blackColor];
questionLabel.tag=1;
questionLabel.font=[UIFont systemFontOfSize:13];
questionLabel.numberOfLines = 0;
[questionLabel sizeToFit];
[myView addSubview:questionLabel];
I had written this code for displaying my data. But if I write: [questionLabel sizeToFit] my data does not display properly. If I remove [questionLabel sizeToFit] then it is displaying but it only shows half the data.
Thanks and Regards.
NSString *yourString = #"write your label text here";
CGSize s = [yourString sizeWithFont:[UIFont systemFontOfSize:12] constrainedToSize:CGSizeMake(width, MAXFLOAT) lineBreakMode:UILineBreakModeWordWrap];
questionLabel.frame = CGRectMake(0, 0, s.width, s.height);
Check if it helps.
I think it's best to use taus-iDeveloper answer to compute the size of a label.
I just want to say that the reason your code is not working is because you didn't set text to your UILabel so sizeToFit returns CGSizeZero (so it doesn't appear on screen). You have to set text before using sizeToFit.
I found that if AutoLayout is on then size to fit not work
i googled d above problem and came across some info that sizeToFit seems to be a bug and it has been reported to apple already.
So as a workaround u can use this code:
NSString * myText = [NSString stringWithString:#"some text"];
CGFloat constrainedSize = 265.0f;
UIFont * myFont = [UIFont fontWithName:#"Arial" size:19];
CGSize textSize = [myText sizeWithFont: myFont
constrainedToSize:CGSizeMake(constrainedSize, CGFLOAT_MAX)
lineBreakMode:UILineBreakModeWordWrap];
CGRect labelFrame = CGRectMake (0, 0, textSize.width, textSize.height);
UILabel *label = [[UILabel alloc] initWithFrame:labelFrame];
[label setFont:myFont];
[label setText:myText];
I've found that when using sizeToFit with a UILabel, in InterfaceBuilder you need to change the Autoshrink property from 'Fixed Font Size' to 'Minimum Font Size'. I usually then set its value to 0.5 to be sure its working properly.
just make sure you increase the number of lines of the label. Instead of
questionLable.numberOfLines = 0; make use of
questionLable.numberOfLines = 4;
As it will force the system to compute the smallest width possible for 4 lines.
You can achieve this via the Xib file too..
I am trying to create a horizontal scroll view which has a UILabel as elements, by doing the following in viewDidLoad:
for(int index=0; index < [self.category count]; index++)
{
UILabel *label = [[UILabel alloc] init];
label.text = [self.category objectAtIndex:index];
label.textColor = [UIColor blackColor];
CGSize maximumLabelSize = CGSizeMake(100,9999);
CGSize expectedLabelSize = [[self.category objectAtIndex:index] sizeWithFont:label.font
constrainedToSize:maximumLabelSize
lineBreakMode:UILineBreakModeWordWrap];
label.frame = CGRectMake(5+xOffset, 0, expectedLabelSize.width, 40);
self.scrollView.contentSize = CGSizeMake(scrollWidth+xOffset,110);
[self.scrollView addSubview:label];
xOffset += 170;
}
However, I can't see anything when I run the app in the simulator, what am I missing here? Pretty sure that the UIScrollView is connected via the IBOutlet and I know that the text exists as I tried printing that out via NSLog
UPDATE:
Also how do I check which UILabel is clicked? I wanted to know this as well..
I think you did'nt initialize xOffset=0 before running for loop. so that it is taking a garbage value and then executing xOffset += 170; instruction.
so please initialize xOffset=0;
If you're positioning the labels with a frame you should also set autoresizingMask to make sure if you position based on a portrait layout but are testing the app in landscape, your labels don't get auto-positioned outside the new bounds. Also, make sure to autorelease those labels or else you'll be leaking memory.
Your expectedLabelSize calculation seems to adjust the height, leaving the width at 100. When you set the frame of your UILabel you are just using this width.
I have created a custom view cell with a UILabel in it, I have set :
cell.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
cell.titleLabel.numberOfLines = 0;
and it's not going in multiple lines, why is this?
in the layoutSubviews I have:
- (void)layoutSubviews {
[super layoutSubviews];
CGRect frame = titleLabel.frame;
frame.origin.y = 5;
titleLabel.frame = frame;
}
and that's about all the settings I have, however for a long text put in the label in the cell it just won't word wrap:
What is the height of the label's frame? It needs to be tall enough to hold more than one line of text. Check out Adjust UILabel height depending on the text
I am trying to give my UILabel dynamic height so that my layout of other labels looks correct in both landscape and portrait.
In portrait, my text wraps to the second line, in landscape it does not. So, when using sizeWithFont:constrainedToSize:lineBreakMode: I get the same height when rotating both ways, when I had assumed it would be a larger number when the text was 2 lines.
How can I get the height of my UILabel when it has two lines of text or more (portrait) and get the new height which is one line, when in landscape?
I guess I am not understanding how to get dynamic height working...
UILabel *itemTitle = [[UILabel alloc] initWithFrame:CGRectMake(10.0f, top, screen.size.width - 20, 200.0f)];
itemTitle.text = self.newsAsset.title;
itemTitle.adjustsFontSizeToFitWidth = NO;
itemTitle.autoresizingMask = UIViewAutoresizingFlexibleWidth;
itemTitle.font = [UIFont boldSystemFontOfSize:18.0];
itemTitle.textColor = [UIColor blackColor];
itemTitle.shadowColor = [UIColor whiteColor];
itemTitle.shadowOffset = CGSizeMake(0, 1);
itemTitle.backgroundColor = [UIColor blueColor];
itemTitle.lineBreakMode = UILineBreakModeWordWrap;
itemTitle.numberOfLines = 0;
[itemTitle sizeToFit];
// Set the height
CGSize maximumLabelSize = CGSizeMake(300,9999);
CGSize titleSize = [itemTitle.text sizeWithFont:itemTitle.font constrainedToSize:maximumLabelSize lineBreakMode:itemTitle.lineBreakMode];
NSLog(#"Height: %.f Width: %.f", titleSize.height, titleSize.width);
//Adjust the label the the new height
CGRect newFrame = itemTitle.frame;
newFrame.size.height = titleSize.height;
itemTitle.frame = newFrame;
// Add them!
[headerView addSubview:itemTitle];
[itemTitle release];
top += titleSize.height;
change the line where you set maximumLabelSize to
CGSize maximumLabelSize = CGSizeMake(headerView.bounds.size.width, CGFLOAT_MAX);
In your code as it is now, in either orientation you will get the same width and height, since you always pass a width of 300 to the sizeWithFont method. If you make it dynamic, maybe the result of the sizeWithFont will also change dynamically.
