Large Text Being Cut Off in UITextView That is Inside UIScrollView

Question

I\'m having a serious problem that I just can\'t seem to fix and it\'s driving me insane for the last two days. I have searched far and wide and I can\'t find a solution, e

Answer 1

None of these answers worked for me.

I was fooling with the storyboard and somehow it's working now. It still looks wrong in the storyboard but on the device it's now displaying fine.

I did various things, including toggling many of the options for the textfield.

I think what fixed it for me was making the view larger, building, and making it the right size again.

My apologies for a vague uncertain answer, but maybe it helps. This project was originally written for iOS 5, and the text view may not have been messed with much since then.

Answer 2

We had an issue like this with the rollout of iOS7. When we called setText which added a new line (or lines) to our UITextView, the textview wasn't using the correct new height for its redrawing. The setNeedsDisplay, setNeedsLayout, redrawing layers, redrawing the entire view, etc all didn't work. Finally we forced a loss and gain of focus:

[textView resignFirstResponder];
[textView becomeFirstResponder];

This forced the height recalculation and correct redraw. Thankfully it does not cause the keyboard to pop out and in, but it's worth regression testing that on any iOS versions your app supports.

Answer 3

For me the solution was to put sizeToFit after customizing the textView

[self.yourTextView sizeToFit];

This should be the last thing you do when manipulating the textview, should not be before you populate the content text.

Answer 4

Definitely iOS7. I had this same problem applying to all UITextViews that were resized, both xib and code generated. I found the textContainer.size needed adjusting after UITextView frame was changed.

I created this category code to adjust the textContainer.size but it also seems to need adjusting after setting the text value as well, so I have to call adjustAfterFrameChange after any text changes if they are not followed by setting the frame size. This code makes the assumption that UITextView is not doing anything with setFrame: itself so take out setFrame: and call adjustAfterFrameChange manually if you want to avoid that risk

Edit: changed

self.textContainer.size = self.frame.size; // fix for cut off text

to

self.textContainer.size = self.contentSize; // fix for cut off text

---

@interface UITextView(Extras)

- (void)adjustAfterFrameChange;

@end



@implementation UITextView(Extras)

- (void)adjustAfterFrameChange {
#if defined(__IPHONE_7_0) && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_7_0
    if ([self respondsToSelector:@selector(textContainer)])
        self.textContainer.size = self.contentSize; // fix for cut off text
#endif
}


- (void)setFrame:(CGRect)frame {
    [super setFrame:frame];

    [self adjustAfterFrameChange];
}

@end

Answer 5

This issue can be fixed by setting the contiguous layout property to false.

textView.layoutManager.allowsNonContiguousLayout = false

Although the documentation says that the default value is false, it is actually set to true for a UITextView.

Answer 6

I am facing the same situation. I have to disable the UITextView's scrolling and doing that causes the last line is cliped. Here is my solution:

//In the  UITextView subClass, override "gestureRecognizerShouldBegin" and let the scrolling of UITextView remain on.

-(BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer
{
    if ([gestureRecognizer isKindOfClass:[UIPanGestureRecognizer class]] && gestureRecognizer.view == self){
        return NO;
    }
    return [super gestureRecognizerShouldBegin:gestureRecognizer];
}
