I want to resize my UILabel according to the UILabel text. The code I have does not make the
UILabel according to its width..
My current code:
UILabel *textLabel2 = [[UILabel alloc] initWithFrame:CGRectMake(20, 158, self.view.bounds.size.width-40, 550)];
textLabel2.text = textString;
textLabel2.font = [UIFont fontWithName:#"Helvetica Neue" size:17];
textLabel2.numberOfLines = 0;
[textLabel2 sizeToFit];
[self.scroller addSubview:textLabel2];
How can I do this?
Some thing like this?
UILabel *label = [[UILabel alloc] init];
//set label backgroundColor so you can see the label width changes according to text
[label setBackgroundColor:[UIColor redColor]];
//edit you label text
[label setText:#"very longgggg text"];
//get width of you text and set you font size to 17.0
CGFloat width = [label.text sizeWithFont:[UIFont systemFontOfSize:17.0f]].width;
//set you label frame
label.frame = CGRectMake(10, 200, width, 30);
//add label to you view
[self.view addSubview:label];

My CATextlayer support only 1 line
otherwise the text is cut.
trying to set text content like UILabel Behaviour... is it possible?
set "number of lines"
adjust text size by static CATextLayer frame
CATextLayer *text_layer= [[CATextLayer alloc] init];
[text_layer setBackgroundColor:[UIColor clearColor].CGColor];
[text_layer setBackgroundColor:[UIColor blueColor].CGColor];
[text_layer setForegroundColor:layers.textColor.CGColor];
[text_layer setAlignmentMode:kCAAlignmentCenter];
[text_layer setBorderColor:layers.borderColor.CGColor];
[text_layer setFrame:CGRectMake(0,0,200,50)]; //note: frame must be static
[text_layer setString:#"thank you for your respond"];
text_layer.wrapped = YES;
[text_layer setAlignmentMode:kCAAlignmentCenter];
Your problem is this line right here, [text_layer setFrame:CGRectMake(0,0,200,50)];. I don't think a CATextLayer would lay itself out to accommodate multiple lines. It will only re-draw the text to wrap within the layer's bounds. Try adjusting your text layer's frame based on the text being set. You can create a UILabel instance, to calculate the frame for having multiline text with word wrapping and set it to your CATextLayer instance.
Here's a UILabel category to calculate text size for multiline text with word wrapping:
#interface UILabel (Height)
- (CGSize)sizeForWrappedText;
#end
#implementation UILabel (Height)
- (CGSize)sizeForWrappedText {
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.bounds.size.width, CGFLOAT_MAX)];
label.numberOfLines = 0;
label.font = self.font;
label.text = self.text;
[label sizeToFit];
return label.frame.size;
}
#end
Create a UILabel instance, and use the sizeForWrappedText to get the size. Something like this:
// Make sure the someFrame here has the preferred width you want for your text_layer instance.
UILabel *label = [[UILabel alloc] initWithFrame:someFrame];
[label setText:#"My awesome text!"];
CGRect frame = text_layer.frame;
frame.size = [label sizeForWrappedText];
[text_layer setFrame:frame];
I have added a UITextView inside a UIView. UIView has some height depending upon screen sizes. UITextView can have more or less text. So I want to make the height of UITextView dynamic so if text is more then it should have more height but it should be less than the height of main view . If text is less then it should have less height.
Size a UITextView to its content programmatically:
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(100, 100, 100, 100)];
[textView setDelegate:self];
[textView setText:#"your long text"];
[textView setScrollEnabled:NO];
[self.view addSubview:textView];
CGFloat fixedWidth = textView.frame.size.width;
CGSize newSize = [textView sizeThatFits:CGSizeMake(fixedWidth, MAXFLOAT)];
CGRect newFrame = textView.frame;
newFrame.size = CGSizeMake(fmaxf(newSize.width, fixedWidth), newSize.height);
textView.frame = newFrame;
If you are using textview to display multilines of text with scrolling disabled, It is nothing more than a UILabel. I suggest you to use UILabel for the purpose.
In the storyboard, set the constraints as follows:
and set the line break as word wrap:
Same as the first answer, but in Swift 4:
let screenSize = UIScreen.main.bounds
let textView = UITextView.init(frame: CGRect(x: 1, y: 40, width: screenSize.width, height: screenSize.height))
textView.delegate = self as? UITextViewDelegate
textView.isScrollEnabled = false
view.addSubview(textView)
let fixedWidth = textView.frame.size.width
let newSize: CGSize = textView.sizeThatFits(CGSize(width: fixedWidth, height: CGFloat(MAXFLOAT)))
var newFrame = textView.frame
newFrame.size = CGSize(width: CGFloat(fmaxf(Float(newSize.width), Float(fixedWidth))), height: newSize.height)
Try with this
-(void)dynamicTextSize{
UITextView *textView = [[UITextView alloc]initWithFrame:CGRectMake(200, 300, 200, 30)];
textView.center = self.view.center;
[self.view addSubview:textView];
NSString *string = #"This is pour text.a hjajksdkja kajhdsjk akjdhs jakhd skjahs ajkdhsjkad hskja akjdhs ajkhdjskar";
textView.text = string;
//UIFont *font = [UIFont fontWithName:#"Arial" size:16.0f];
NSDictionary *attrDict = [NSDictionary dictionaryWithObjectsAndKeys:textView.font, NSFontAttributeName, nil];
textView.backgroundColor = [UIColor lightGrayColor];
CGRect frame = [textView.text boundingRectWithSize:CGSizeMake(textView.frame.size.width, 10000) options:NSStringDrawingTruncatesLastVisibleLine|NSStringDrawingUsesLineFragmentOrigin attributes:attrDict context:nil];
CGRect mFrame = textView.frame;
mFrame.size.width = frame.size.width;
mFrame.size.height = frame.size.height;
textView.frame = mFrame;
//NSLog(#"frame2:%#",NSStringFromCGRect(textView.frame));
}
I've a label in a table cell and I wish to add padding to top,bottom,left and right.
CGRect initialFrame = CGRectMake(10,10,100,20);
UIEdgeInsets contentInsets = UIEdgeInsetsMake(5, 0, 5, 0);
CGRect padd = UIEdgeInsetsInsetRect(initialFrame, contentInsets);
self.rewardLabel = [[UILabel alloc] initWithFrame:padd];
self.rewardLabel.backgroundColor =[UIColor colorWithRed:0.192 green:0.373 blue:0.561 alpha:1];
self.rewardLabel.layer.cornerRadius = 5.0f;
self.rewardLabel.layer.masksToBounds = YES;
self.rewardLabel.textColor = [UIColor whiteColor];
self.rewardLabel.lineBreakMode = NSLineBreakByWordWrapping;
self.rewardLabel.numberOfLines = 1;
self.rewardLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:14];
[self.contentView addSubview:self.rewardLabel];
But it seem like not working. Can anyone tell me how to do?
There are several ways on how to achieve this:
If you do not need a specific background color for your label you could just adjust the labels frame to add the padding (e.g. if your text should start 20px from the cell's left side, set the label's frame's x to 20).
To really add a padding, you could use a custom UILabel subclass and override its drawTextInRect: and intrinsicContentSize methods. (See this question for details)
If you just need a left and right padding you could use an NSAttributedString to add insets to UILabel:
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 40)];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.headIndent = 5.0;
paragraphStyle.firstLineHeadIndent = 5.0;
paragraphStyle.tailIndent = -5.0;
NSDictionary *attrsDictionary = #{NSParagraphStyleAttributeName: paragraphStyle};
label.attributedText = [[NSAttributedString alloc] initWithString:#"Your text" attributes:attrsDictionary];
I have UILabel in my View that should resize itself based on the content, but it doesn't do so. I have multiline content in it. I tried [label sizeToFit] + label.numberOfLines= 0.
I don't have constraints for the UILabel.
I also tried to use UITextView instead, but there the font just stays on 13 and not as I want on 17. Can you help me?
This is the code that works now:
UILabel *textLabel2 = [[UILabel alloc] initWithFrame:CGRectMake(20, 158, self.view.bounds.size.width-40, 550)];
textLabel2.text = textString;
textLabel2.font = [UIFont fontWithName:#"Helvetica Neue" size:17];
textLabel2.numberOfLines = 0;
[textLabel2 sizeToFit];
[self.scroller addSubview:textLabel2];
If you are creating your UILabel programmatically:
This code first sets the UIlabel's text then get the width of the text
UILabel *label = [[UILabel alloc] init];
//set label backgroundColor so you can see the label width changes according to text
[label setBackgroundColor:[UIColor redColor]];
//edit you label text
[label setText:#"very longgggg text"];
//get width of you text and set you font size to 17.0
CGFloat width = [label.text sizeWithFont:[UIFont systemFontOfSize:17.0f]].width;
//set you label frame
label.frame = CGRectMake(10, 200, width, 30);
//add label to you view
[self.view addSubview:label];
If you're not creating you UILabel programmatically remove the alloc init line and connect you outlets to you xib or storyboard.
I am trying to show into the header of my UITableViewController a title and under it an image illustrating the title. The next code (written into the viewDidLoad method) shows only the image, and this image over the rest of the table sections. How I can fix it to do what I want?
// Creates a header view.
UIView *containerView = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 60)] autorelease];
UILabel *headerLabel = [[[UILabel alloc] initWithFrame:CGRectMake(10, 20, 300, 40)] autorelease];
headerLabel.text = self.name;
headerLabel.textColor = [UIColor blackColor];
headerLabel.font = [UIFont boldSystemFontOfSize:16];
headerLabel.backgroundColor = [UIColor clearColor];
GRect imageRect = CGRectMake(0.0f, 0.0f, 320.0f, 109.0f);
UIImageView *headerImage = [[UIImageView alloc] initWithFrame:imageRect];
UIImage *image = [UIImage imageNamed:self.imagePath];
[headerImage setImage:image];
headerImage.opaque = YES;
[containerView addSubview:headerLabel];
[containerView addSubview:headerImage];
self.tableView.tableHeaderView = containerView;
Thanks for reading.
Just adjust the views' frames accordingly. The container view's frame must be tall enough to contain the label and image view, and the image view's y coordinate must be set so that it is positioned below the label. The frame rects you are using in your code do not match.
