Trying to position a UILabel above some text, but the elements are "stepping" on each other. I positioned them with x,y,h,w such that they should not do this but alas, they are. You can see in the screenshot that the label text "Abalone" and the text are commingled. What changes do I need to make here? I've already tried changing the x,y,w,h values to no great effect...
txtView = [[UITextView alloc] initWithFrame:CGRectMake(10,20,280,300)];
[txtView setFont:[UIFont fontWithName:#"ArialMT" size:14]];
txtView.text = word.definition;
txtView.editable = NO;
txtView.scrollEnabled = YES;
[txtView scrollRangeToVisible:NSMakeRange([txtView.text length], 0)];
txtView.minimumZoomScale = 1;
txtView.maximumZoomScale = 10;
UILabel *wordTitle = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, 250, 20)];
wordTitle.text = word.term;
[txtView addSubview:wordTitle];
[detailsViewController.view addSubview:txtView];
I think the problem is you are adding the label view as a subview to UITextview. You have to reserve some space for the label view in the UITextview. You can either add some padding to the textView, which can be confusing, because padding in UITextView is not constant and varies based on the font size. Or you can add your UILabel directly to the detailsViewController.view and start your UITextView below the label.
Hope it helps.

Is it possible to set a UITextField's input range (not the number of characters)? You can check out my screenshot below.
I already tried implementing this: Ellipsis at the end of UITextView
It didn't work, or I'm just doing it wrong.
What I want is to limit the size of the user's input AND make it ellipsis. The text at the left side of UITextfields are merely UILabels set as subviews.
So again... I need help in setting the range of the text input, and if the input length or width overlaps my RED MARK in my screenshot, the rest of the input will be converted to POINTS OF ELLIPSIS. And then I'm pretty sure I can now proceed to my project (example: clicking the arrow button will make a small popup that will show the full text).
I forgot to add my codes in that UITextField:
self.billingAddressTextField = [[UITextField alloc] init];
_billingAddressTextField.frame = CGRectMake(0, 150, scrollView.frame.size.width, 50);
_billingAddressTextField.delegate = self;
_billingAddressTextField.borderStyle = UITextBorderStyleNone;
_billingAddressTextField.background = [UIImage imageNamed:#"textfieldLogIn.png"];
[_billingAddressTextField setTextColor:[UIColor colorWithRed:0.686 green:0.686 blue:0.686 alpha:1.0]];
_billingAddressTextField.backgroundColor = [UIColor clearColor];
_billingAddressTextField.autocapitalizationType = UITextAutocapitalizationTypeWords;
[_billingAddressTextField setFont:[_billingAddressTextField.font fontWithSize:16.0f]];
[_billingAddressTextField setTextAlignment:NSTextAlignmentRight];
[scrollView addSubview:_billingAddressTextField];
Ok solved, I just added a new Padding (UIView) at the left side of the UITextField (billingAddressTextField). So there are now two paddings (both side) in my UITextField.
UIView *paddingViewForArrowButton = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 35, 25)];
_billingAddressTextField.rightView = paddingViewForArrowButton;
_billingAddressTextField.rightViewMode = UITextFieldViewModeAlways;
UIView *paddingforBillingLeft = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 100, 25)];
_billingAddressTextField.leftView = paddingforBillingLeft;
_billingAddressTextField.leftViewMode = UITextFieldViewModeAlways;
I have a UITextField that I'm trying to center in a UIView. However, when I call sizeToFit it leaves a small right margin in the textField which causes the text to be slightly off center when the textField background is clear. I've colored it here so you can see what I'm talking about:
messageField = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 0, 0)];
messageField.delegate = self;
messageField.font = [UIFont systemFontOfSize:15];
messageField.textColor = [UIColor darkGrayColor];
messageField.textAlignment = NSTextAlignmentLeft;
messageField.attributedPlaceholder = [[NSAttributedString alloc] initWithString:#"not fitting right" attributes:#{NSForegroundColorAttributeName: [UIColor darkGrayColor]}];
[messageField layoutSubviews];
[messageField sizeToFit];
messageField.backgroundColor = [UIColor lightGrayColor];
And the textfield looks like this (I would post a picture but need more reputation points, this is basically the same though):
not fitting right
Any help would be greatly appreciated!
I should not that if I create a UILabel of the same font size and text, call sizeToFit on the label and then assign the UITextField frame to be the same as the UILabel, it works like a charm.
I've been trying to figure out how to vertically align my UILabel text to the top or bottom. The problem is, I have an image behind it which also gets shifted with the text.
Is there a way to keep the background color/image in place, but only shift the text up or down?
Here's the current code:
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (!self) return nil;
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0,
0,
frame.size.width,
frame.size.height)];
label.textAlignment = NSTextAlignmentLeft;
label.font = [UIFont fontWithName:#"AvenirNext-Bold" size:12];
label.backgroundColor = [UIColor clearColor];
[self addSubview:label];
self.numberLabel = label;
self.layer.cornerRadius = 3;
return self;
}
I've been following this tutorial, but it shifts everything, including my label background.
Vertically align text to top within a UILabel
find the height of the text.
Use another view to show image.
Set frame of label relative image view with height of the text and whatever position you want to set for label.
ON the label if you're not using auto layout use:
[YOUR_LABEL sizeToFit];
This will resize your label to fit the text.
What is the background image ? A separate UIImageView ? How are you setting this image ?
Any way to have multiple lines of text in UILabel ?
I dont wish to more than 1 label in the view.
How to add multiple lines in a single UILabel??
Yes there is a way. Just you need to add two property of UILabel i.e.
NumberOfLines=0 It'll allow you to add multiple lines in a UILabel
LineBreakMode = NSLineBreakByWordWrapping It'll allow you to break your sentence by word. You can also change it according to your requirement.
[YourLabel setNumberOfLines:0];
[YourLabel setLineBreakMode:NSLineBreakByWordWrapping];
You can also set this two property form your interface builder
here is a sample code
UILabel *pHolder1 = [[UILabel alloc]initWithFrame:CGRectMake(5, 0, 245, 45)];
pHolder1.backgroundColor = [UIColor clearColor];
pHolder1.font = [UIFont systemFontOfSize:14.0f];
pHolder1.numberOfLines =0;
pHolder1.lineBreakMode = NSLineBreakByWordWrapping;
pHolder1.textAlignment = NSTextAlignmentCenter;
Dynamically calculate the height of UILabel
please refer the below post
Adjust UILabel height depending on the text
Here is sample code:
UILabel *lblUsername=[[UILabel alloc] init];
StoryTextSize = [storytext sizeWithFont:[UIFont fontWithName:#"Georgia" size:13.0f] constrainedToSize:CGSizeMake(300, MAXFLOAT) lineBreakMode:NSLineBreakByWordWrapping];
lblUsername.frame=CGRectMake(20, 5, [[UIScreen mainScreen] bounds].size.width-40, StoryTextSize.height);
lblUsername.textColor=[UIColor blackColor];
lblUsername.text=[NSString stringWithFormat:#"%#",[[tblRecords objectAtIndex:indexPath.row] valueForKey:#"username"]];
lblStoryText.numberOfLines=nooflines;
lblStoryText.backgroundColor=[UIColor clearColor];
[self.view addSubview:lblStoryText];
make sure that your label height should be more so total no of lines become visible.
When I add text to a label with the adjustsFontSizeToFitWidth set to YES the text is no longer centred vertically and eventually clips the text at the bottom of the label frame. For a large amount of text it will eventually disappear off the bottom of the label.
This is what happens if you add less text:
This is clipped as I would expect it (i.e. the font size did not reduce, the text was vertically centred in the label and clipped on the top and bottom.
Here is the code to reproduce:
- (void)loadView {
[super loadView];
self.view.backgroundColor = [UIColor blueColor];
testLabel = [[UILabel alloc] init];
testLabel.font = [UIFont boldSystemFontOfSize:172];
testLabel.textColor = [UIColor blackColor];
testLabel.adjustsFontSizeToFitWidth = YES;
testLabel.numberOfLines = 1;
testLabel.frame = CGRectMake(50, 50, 300, 100);
testLabel.text = #"123";
[self.view addSubview:testLabel];
}
Should this happen? And how do I get my label to centre vertically irrespective of the number of characters in my label.
Add
testLabel.baselineAdjustment = UIBaselineAdjustmentAlignCenters;
to your code to vertical-center the text on font scale.
Would also like add that adjustsFontSizeToFitWidth doesn't work too well with attributed text, so add your attributes to the label instead of the attributed text if you can. This worked for me.
