Double-click it to edit text, place cursor where you want the paragraph break. Hit alt-Enter a couple of times to create a blank line & paragraph. Or, CTRL + Return make a new … Read more
You may have changed the tint color in your custom UITextView. If the tint color is the same as the background color (normally white), then it will appear invisible.
First add an observer for the contentSize key value of the UITextView when the view is loaded: – (void) viewDidLoad { [textField addObserver:self forKeyPath:@”contentSize” options:(NSKeyValueObservingOptionNew) context:NULL]; [super viewDidLoad]; } Then add this method to adjust the contentOffset every time the contentSize value changes: -(void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { UITextView *tv = object; … Read more
With this following code, you can change the height of your UITextView depending of a fixed width (it’s working on iOS 7 and previous version) : – (CGFloat)textViewHeightForAttributedText:(NSAttributedString *)text andWidth:(CGFloat)width { UITextView *textView = [[UITextView alloc] init]; [textView setAttributedText:text]; CGSize size = [textView sizeThatFits:CGSizeMake(width, FLT_MAX)]; return size.height; } With this function, you will take a … Read more
I had the same problem, and turns out I had to set the content offset in viewDidLayoutSubviews for it to take effect. I’m using this code to display attributed static text. – (void)viewDidLayoutSubviews { [self.yourTextView setContentOffset:CGPointZero animated:NO]; } SWIFT 3: override func viewDidLayoutSubviews() { super.viewDidLayoutSubviews() self.textView.setContentOffset(CGPoint.zero, animated: false) }
Maciek Czarnik answer does not worked for me, but it got me insights what to do. iOS 7+ Swift textView.textContainer.maximumNumberOfLines = 10 textView.textContainer.lineBreakMode = .byTruncatingTail ObjC textView.textContainer.maximumNumberOfLines = 10; textView.textContainer.lineBreakMode = NSLineBreakByTruncatingTail;
– (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text { return textView.text.length + (text.length – range.length) <= 140; } This accounts for users cutting text, or deleting strings longer than a single character (ie if they select and then hit backspace), or highlighting a range and pasting strings shorter or longer than it. Swift 4.0 Version func textView(_ … Read more
Use following block of code for ios 7+. NSString *htmlString = @”<h1>Header</h1><h2>Subheader</h2><p>Some <em>text</em></p><img src=”http://blogs.babble.com/famecrawler/files/2010/11/mickey_mouse-1097.jpg” width=70 height=100 />”; NSAttributedString *attributedString = [[NSAttributedString alloc] initWithData: [htmlString dataUsingEncoding:NSUnicodeStringEncoding] options: @{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType } documentAttributes: nil error: nil ]; textView.attributedText = attributedString;
Although it is iOS 7 only, an extremely clean solution is to set the textView’s textContainerInsets as such: [textView setTextContainerInset:UIEdgeInsetsZero]; textView.textContainer.lineFragmentPadding = 0; // to remove left padding This will effectively remove all padding (insets) around the text inside the text view. If your deployment target is iOS 7+ then this is the best solution … Read more
UITextView*note; [note setContentOffset:CGPointZero animated:YES]; This does it for me. Swift version (Swift 4.1 with iOS 11 on Xcode 9.3): note.setContentOffset(.zero, animated: true)
