I Would like to embed the ZSSRichTextEditor in UITextView / UIWebView.
I am having a form with fields which will be filled by the user. One of the fields needs to be formatted by user as in ZSSRichTextEditor. I tried the UITexView inline custom formatting. But failed to convert the attributtedString to HTML and the reverse. Any suggestions please.
ZSSRichTextEditor wasn't built to work with a UITextView. All the functionality that we built into it requires UIWebView to function. It IS an HTML editor.
If you try to force it to work with a UITextView, pretty much every function will no longer work.

In the app I am currently developing, I have to implement a screen which allows the user to ask a question. This screen contains a UIImageView next to the UITextView, taking up a portion of the space. It looks like the below image.
My question is, how can I wrap the UITextView text around the UIImageView, so that the text won't be in a block, but flowing around the UIImageView?
Thanks in advanced.
I don't think you can do this, unless your UITextView was a rich text or HTML editor, with the image embedded inside it. Basically what you're asking for is a non-rectangular UITextView. To the best of my knowledge, that is impossible in iOS, unless you were to create something brand new from scratch, which would be extremely complex. I have seen plenty of UILabel-style controls that can display HTML-like text, but not edit it.
EDIT: this might help: http://www.cocoanetics.com/2011/01/rich-text-editing-on-ios/
Unfortunately that's not a trivial issue as the UITextField does not provide any functionality that would be useful here.
However what you could do is to implement your own text view using UITextInput (for text input) and Core Text (for text display) and then define the drawing rectangle for Core Text (you can read more on Core Text here) from a custom CGPath that would exclude the images frame.
It does sound a bit complex (insane, perhaps), however as (nearly always) there are open source solutions that already found a solution. The OmniGroup framework contains custom text input controls based on Core Text and UITextInput. They're licensed under MIT License (well, moreless) so you should be just fine.
This is a real n00b question but i am very new at this and have been looking for an answer and also read the reference as i am trying to work with UITextView.
I want to add quite a lot of text into a view and i want it to be scrollable.
I have created the UITextView in IB, added text via "self.myTextView.text = #"...", which works. However i am not able to scroll down and see all text. I see only the amount of text that fits in the view i have.
I wonder if someone nice could help me and give an example/hint how to get the UITextView scrollable.
Thank you.
If it's static text and you'd like some formatting, I recommend using a UIWebView. You can give it a variety of files types, and edit the file easily.
I encoutered an essential problem while making an iPad app, where u HUGE amount of text will be displayed.
I need to create blocks of text that can line break and also be linkable(for calling certain functions on each block). I thought that Core Text should be used.
Which is the way to assign the position of touch with necessary block of text?
and does anyone has any examples? google is poor on it, when it's about working with some amounts of text.
You can use a transparent button in overlay of the text.
You can not make your text linkable as in a html page. You can do this feature only in Webview.
I am trying to implement a control to edit text that will display the text in multiple colors. None of the solutions I have attempted yet have been good enough.
UITextView cannot accomplish this. All of the text must be the same color.
Using CoreGraphics to draw the text does not allow the text to be selected.
Using a UIWebView, DIV and PRE tags cannot be set to contentEditable on Mobile Safari.
Currently playing with using an off-screen TEXTAREA and an on-screen DIV to show the rendered text. This works pretty well, except supporting all of these at the same time seems impossible: click-to-type, click-to-move-cursor, click-and-hold-select/copy/paste.
Anyone have any tips on this predicament?
I've been trying to find any preexisting library out there that will accomplish this in a good way, to no luck. I'm open to any ideas!
Well, just pulling an idea out of my... let's say hat.
Could you put a transparent UITextfield over a view that draws the text? If the background was clear and the text color was clear the user could not perceive it but it should still respond to all commands. As the user enters and edits text you could draw the results on the view underneath.
I think the selection would work without any modification at all. When the user selected the clear text, it should create the illusion of selecting the drawn text automatically.
Like this one? StyledText http://three20.info/gfx/overview/styledtext.png It's in Three20 .
Here is an idea. I have no idea if it would work.
If you are only using colors, and not styles, the a UIWebView with colored text might layout text in exactly the same way as a UITextView. You could put a UITextView with invisible ink (text and background fully transparent) over a UIWebView and mirror the contents with colors in the html. I assume you can do scrolling with javascript along with the colored layout.
I'm fairly new to iPhone programming and am trying to implement a double-component PickerView. At this point the picker works fine in terms of taking user input, created with Interface Builder. However, I need to change the font size to accommodate the text length in each column. I very much would appreciate any link to a straightforward method to creating a multi-component picker with an adjustable font size. Seems like it is not possible if Interface Builder is used to create the picker. So far I have not found any code links that address this issue in detail.
Thanks in advance.
You need to implement the delegate method...
pickerView:viewForRow:forComponent:reusingView:
... and then alter the font of the UI element inside the provided view. I think the default is a UILabel. Alternatively, you can provide your own custom view.
