iOS 8 - Crash

[Sergi Solanellas]

Inside of method "UpdateText", the line "_textView.textContainer.lineFragmentPadding = 0;" crashes.

I need to test app with iOS8, and I repaired with this code ( while you revise the problem ):

- (void)updateText
{
    NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:_cleanText];
    [attributedString setAttributes:_attributesText range:NSMakeRange(0, _cleanText.length)];

    for (NSDictionary *dictionary in _rangesOfHotWords)  {
        NSRange range = [[dictionary objectForKey:@"range"] rangeValue];
        STTweetHotWord hotWord = (STTweetHotWord)[[dictionary objectForKey:@"hotWord"] intValue];
        [attributedString setAttributes:[self attributesForHotWord:hotWord] range:range];
    }

    [_textStorage appendAttributedString:attributedString];

    _textContainer = [[NSTextContainer alloc] initWithSize:CGSizeMake(self.frame.size.width, CGFLOAT_MAX)];
    [_layoutManager addTextContainer:_textContainer];
    [_textStorage addLayoutManager:_layoutManager];

    if (_textView != nil)
        [_textView removeFromSuperview];

    _textView = [[UITextView alloc] initWithFrame:self.bounds textContainer:_textContainer];
    _textView.delegate = self;
    _textView.autoresizingMask = UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth;
    _textView.backgroundColor = [UIColor clearColor];

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_8_0
    // iOS 8+ code here
#else
    // Pre iOS 8 code here
    _textView.textContainer.lineFragmentPadding = 0;
    _textView.textContainerInset = UIEdgeInsetsZero;
#endif

    _textView.userInteractionEnabled = NO;
    [self addSubview:_textView];
}

Hello Sergi,

Thank you for this bug report and also for the potential fix. I will take a look to this issue the next few days/weeks. I'm waiting the next betas. I don't like "fixing" a problem with a first beta. The goal is to launch STTweetLabel 4.0 in August/September written in Swift.

Once again, thank you for your help!

Hello Sebastien,

I tried XCode6 Beta5 and it happens the same problem. I don't know how to fix it, but it seems the problem is something about execute this method without main thread. It's possible?

Thanks :)

Hello all,

Trying to fix your problem but I cannot reproduce it with iOS 8 beta 5. Any steps to reproduce it?

I use STTweetlabel inside cellForRowAtIndexPath like this:

'
STTweetLabel *LDescrip = [[STTweetLabel alloc] initWithFrame:CGRectMake(20, 88, 280, [self heightStringWithEmojis:[[allHeader objectAtIndex:0] descrip] fontType:[UIFont fontWithName:@"HelveticaNeue" size:16.0] ForWidth:280])];

        __typeof(self) __weak weakSelf = self;
        [LDescrip setDetectionBlock:^(STTweetHotWord hotWord, NSString *string, NSString *protocol, NSRange range) {

            switch (hotWord) {
                case STTweetHandle:
                    [weakSelf openPerfilUser:string];
                    break;
                case STTweetHashtag:
                    // Do nothing
                    break;

                case STTweetLink:
                    [weakSelf openHTMLLink:string];
                    break;
            }

        }];

        [LDescrip setText:[[allHeader objectAtIndex:0] descrip]];
        [LDescrip setFont:[UIFont fontWithName:@"HelveticaNeue" size:16]];
        [LDescrip setTextColor:[UIColor colorWithRed:102/255.0 green:102/255.0 blue:102/255.0 alpha:1.0]];
        [LDescrip setNumberOfLines:0];
        [LDescrip setBackgroundColor:[UIColor clearColor]];
        [cell.contentView addSubview:LDescrip];
