I have read a lot of posts about this yet, but I didn't get to a good result. I would like to, for example, have a UIDetectorType for Hashtags in a UITextView.
Isn't there a way to subclass to accomplish this? It seems odd of apple to just have these detector types and no customization(as they even have a twitter-keyboard in the SDK).
Is there an approach but laying buttons over the text where it's necessary?
you can set the tintColor of the UITextView. It affects the link color as well as the cursor line and the selected text color.

I am trying to achieve something like this for iOS in Objective C.
The fill in the blanks(UITextField) should be inline, and should be able to have its own inputType.
Also, each View is a type of cell.contentView of a UITableViewCell.
My current approach is to find the length of string and also calculate the wrapping content length to the next line. Calculate the x's and y's for UITextField and add another UILabel after the UTextField
Is there any other approach other than this?
As EmilioPelaez says, this is not exactly an answer to your question, but a suggestion:
You can use a collection view with an horizontal flow for each "sequence" (i.e. UILabel-UItextfield-etc...)
That collection view has 2 kind of cell:
One with a uilabel with the number of line set to "1"
and the correct layout to fit the cell.
Another with a uitextfield and the correct layout
Coupled with:
My current approach is to find the length of string and also calculate the wrapping content length to the next line.
You may be able to easily adjust the width of the different cells, hide a uitextfield (if needed) and display a more dynamic "sequence" (if needed)
This is not exactly an answer to your question, instead it's a suggestion for a different interaction.
I think that instead of using inline textFields, you could use a UILabel with an attributed string, and in where the textFields would be, you add a different character with a different color that you can tap (For example, this character ✚).
When tapped, you can show an overlay with a text input, and once that input is completed, you update the label with the text (still tappable, and with a different color).
I think this answer might also be relevant: Detecting taps on attributed text in a UITextView in iOS
I think your solution of separating the UILabels and calculating their required positions is a good one for versions lower than iOS9, but if you can count on iOS, UIStackView can dramatically simplify the process for you. You can read more about the process in this tutorial:
UIStackView Tutorial
Good luck!
In Mail.app, if I go to create a new message and type all the way so the text is at the last line of the UITextView there is still a decent amount of space between the last line of text and the keyboard if you scroll down. But you can't type here. It's just nice padding so you can read it without it being scrunched against the keyboard, and if you select the text, the selection handles don't extend under the keyboard.
My question is, how do I mimic this with a traditional UITextView?
I think you can do this by setting the contentInset property of your UITextView:
myTextView.contentInset = UIEdgeInsetsMake(-4,-8,0,0);
btw... the values above are not specific to your situation. You will want to adjust these to get the inset you are looking for.
I need to draw text with a background. I need the background to be not just a square but to wrap the lines.
So using the background color of a UILabel is no good for me.
I suppose I need to draw it, but I dont know how..
Just to be clear, I don't want a square background like this:
I want background like this:
p.s.
I really don't want to use more then one label to get this effect...
I also need it to support ios 4.3 so I can't use new things like NSAttributedString.
You can't do it easily with UILabel element on iOS 4. For example you can override UILabel class and play with calculating text width and then setting black views to the background, which is not an easy job.
I suggest you to use UIWebView instead. You can simply use HTML and CSS rules.
I have a narrow UITextView (about 1 line in height) to which I only add text programmatically, setting the text property of it as I click buttons. I also handle the cursor position manually, setting the selectedRange as the text changes. All works great as long as I have only one line of text.
When I have two or more lines of text and try to insert text at the first line, the text is inserted correctly and the cursor position is still at the right place but the UITextView scrolls to the bottom. When I then add another piece of text at the top it scrolls up to the "correct" position. This pattern then repeats for every entered piece of text at a line other than the last, making the UITextView scroll up and down for every button pressed.
I also tried calling UITextView scrollRangeToVisible: passing the selectedRange property as argument after setting the new text. That didn't work either.
I finally tried setting selectedRange after a 0.5 s delay after I set the text. Then it works as it should, but only after the UITextView has first been scrolled down to the bottom for 0.5 s. This seems to indicate that the setText method of UITextView is asynchronous in some way, and completes after I have already set selectedRange or called scrollRangeToVisible, and readjusts the UITextView to what it believes is the desired.
Can anyone tell me what is going on, and how I can get around the problem.
Thanks!
The auto scroll behavior of UITextFields can be annoying and difficult to harness at times.
Do you need the user to manually edit the text? If not, use a multiline UILabel.
If yes, also use a multiline UILabel and exchange it on the fly against a UITextView once the user taps. Change it back on didEndEditing. This techniques has worked well for me in table views.
I solved the problem!
When starting in the maze of creating a custom input view, I began implementing UITextInput and I found that the UITextInput protocol declares many interesting methods. And what is awesome is that UITextView implements that protocol. So even though it's not in the immediate UITextView API reference, you can call all UITextInput methods on your UITextView. For instance insertText: (from UIKeyInput protocol) and replaceRange:withText:. They made it much more flexible to programmatically work with a UITextView. Hope this can help someone else too!
How do you add counts inside of a UITableView UITableViewCell like the iOS Mail app?
In addition to DDBadgeViewCell (mentioned by #micpringle), there's also TDBadgedCell.
I tried out both and found TDBadgedCell to suit my needs more, as it puts the badges over the cell's text rather than under it, meaning the badges are visible even for cells with long texts.
The project also seems to be (currently, at least) more active than DDBadgeViewCell. (That being said, there seems to be a bug in the non-ARC version of TDBadgedCell.)
Create a custom UITableViewCell, position the labels where you want them (title, subtitle, count, whatever you need). I highly recommend Matt Gallaghers custom UITableView code - it takes a lot of the headaches out of dealing with custom rows. You'll have to follow Matt Gallaghers steps for customizing the cell.
To get the appearance of the count label as close as possible to your example (mail.app), you'll have to set the UILabel backgroundColor to gray (or whatever color you want it to be), textColor to white, and layer.cornerRadius to something equal to half the height of the label (if label is 20 high, cornerRadius should be 10). This will result in a UILabel with white text, gray background, round corners. Note - this isn't the most efficient method of doing this, but Apple hasn't put up the WWDC session video where they explain the performant method better (I missed that session).
The easiest solution would be to set an UILabel as accessoryView or using a custom UITableViewCell subclass which could be designed using IB.
I'd recommend creating a simple rounded UIView and a UILabel as a subview in it. I'd probably create a UITableViewCell subclass to manage the content.
Definitively the most easy way would be using a ready-to-use class like TDBadgedCell
