liveui / ftcoretext Goto Github PK

App crashes when parsing this string
@"<a href="http://www.w3schools.com/html/\">Visit our HTML tutorial"
What can be done?

FTCoreText is very cool, but performance is really low in UITableView. I found two ways to improve it:

1. Regular expressions use a lot of resources, so I've changed - (void)processText method:
   replaced
   tagRange = [processedString rangeOfString:regEx options:NSRegularExpressionSearch range:remainingRange];
   with
   NSRange openSign = [processedString rangeOfString:@"<"];
   NSRange closeSign = [processedString rangeOfString:@">"];
   if (openSign.location != NSNotFound && closeSign.location != NSNotFound) {
   tagRange = NSMakeRange(openSign.location, closeSign.location - openSign.location + 1);
   } else {
   tagRange.location = NSNotFound;
   }
2. CTFontCreateFromUIFont is also very heavy, so I save CTFontRef into FTCoreTextStyle. Also I changed FTCoreTextStyle property to retain (in FTCoreTextNode).

Hope this helped.

I change the code in FTCoreTextAppDelegate.m:

    UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:articleVC];
    [self.window setRootViewController:nav];

The FTCoreText only display part text,because it's frame height is wrong.

FTCoreTextView delegate prooerty use "assign", sometime cause wild pointer crash！！！You need changed to "weak"。

Hi,
First of all thanks for this github.
Well I was just wondering how to create a pages.
I tried to add the tag but it still show all the text in the same page. As well as added code for the style;
//txt file
hey there new page < page/ >
I am on new page

//Style
FTCoreTextStyle *pageStyle = [FTCoreTextStyle styleWithName:@"_page"]; // using fast method pageStyle.name=FTCoreTextTagPage;
[result addObject:pageStyle];

Please guide me....
Thanks & Regards,
Zahur

There's one default tag for bullets -- <_bullet>.

But I might want different kinds of bullet styles, which would require being able to define custom bullet tags. I could now workaround this by giving <_bullet> a different style in different FTCoreTextViews, but then I would not be able to mix different bullet styles in one view.

It would be nice if when on touchesBegan you could set an alternate style for that tag (like underlining, textColor change, etc), which then reverts on touchesEnded.

Is there an appropriate way to append text into an existing FTCoreTextView? Should I be keeping a separate buffer of the text and calling -setText every time I append something new to the buffer? Or does there need to be an -appendText method on FTCoreTextView that handles things more efficiently internally?

now i need to open a new tag inside a predefined tag ??? Does FTCoreTextView can do this ?Thanks ahead !

Hi,

If we have two links which are appearing in one text line, touchedFrame (CGRect) of these links are always the same value. This rect value is the rect value of the last link in the line. It seems that the rect of first links are overridden by the rect value of last link.

The issue has been also found at #19

Hey,

Thanks for sharing the code.
I would be cool, if you could integrate CocoaPod (more infos: https://github.com/CocoaPods/CocoaPods )

I'm using a multiple line FTCoreTextview, with centered text and links that start on one line and continue on the next. The touchable area of the link seems to be calculated as if it's aligned to the left. This means that the second part of the link is unclickable - or very hard to click, depending on the distance of the left.
When I align to the left it works fine though.

Hi,
cool class, very lean and does the job. I encountered a small issue when using this in a UITableView.
Some random text seemed to be highlighted as link. It seems the markers are not cleared properly, so I added
[self.markers removeAllObjects];

in the "processtext" method (class FTCoreTextView).

when text has the "<" or ">" characters in string, the code identify them as undefined tag but crash because it's not closed or not opened .... I solved it by ignoring the undefined tags and continue processing from location after it.

what do you think.

Right now, the bullet tag defines one style that applies both to the bullet glyph and to the text associated with the bullet. For instance, font overrides bulletFont and color overrides bulletColor. After the following style, the bullet and the text are green and sixteen point:

FTCoreTextStyle *bulletStyle = [defaultStyle copy];
bulletStyle.name = FTCoreTextTagBullet;
bulletStyle.bulletFont = [UIFont fontWithName:@"TimesNewRomanPSMT" size:32.f];
bulletStyle.bulletColor = [UIColor orangeColor];
bulletStyle.bulletCharacter = @"❧";
bulletStyle.font = [UIFont fontWithName:@"Helvetica" size:16.0f];
bulletStyle.color = [UIColor greenColor];

It would be good if there could be two styles. Then you could use one font and colour for the bullet glyph (e.g., blue, Webdings) and the letter glyphs from another (e.g., black, Helvetica).

In addition, I may be wrong, but I think defining a separate style for the bullet text is necessary just to support the usual indentation of the non-initial lines of text associated with a list item, as it works for in HTML for instance. I'd be very interested in helping with this but I'm not sure where to start.

For instance, I am not sure how to use CoreText to produce this indentation style, or if what I've suggested is the approach that best fits the component's close fit to CoreText's own model

Although FTCoreText was not specifically created to substitute a UIWebView, some people asked me how it does compared to it.
The answer is I really do not know. So I set up a "Profiler" branch with all the convenient componentes to load the view first in FTCoreTExt and then in UIWebview. Once the view load you can see on the top left corner the number of characters loaded as a reference to how performance change with different text length.
It would be very helpful if someone can point out a way to do proper tests against it.

Hi there,

Thanks for the wonderful class. I am looking to use this in my project, however, am wondering if there is a way to handle links rather than just opening safari?

how i can select text

I am using FTCoreTextView and have noticed two issues with the location of the link as received in the delegate function:

• (void)coreTextView:(FTCoreTextView *)acoreTextView receivedTouchOnData:(NSDictionary *)data
  {
  ...
  CGRect touchedFrame = CGRectFromString([data objectForKey:FTCoreTextDataFrame]);

1. The Y value is always too large, by about the font size. I may be miscalculating something, but that's what I'm seeing.
2. If there are multiple links on a line, I always get the same frame.

I am using this in conjunction with a popup, so I really notice these issues. #1 I can work around, but #2 makes for an awkward UX.

Hi,
It would be awesome if we can load images remotely :) ! I tried to but it did not work. Maybe you can edit my code to implement it easier in the repo ? look at this : stackoverflow.com/questions/11927942/ios-core-text-loosing-context-when-drawing-image-inside-a-block

here is the screenshot of my code ! The delegate method doesn't execute ,but the method "coreTextViewfinishedRendering:" is just ok !

can anbody explain why ?
