On a computer you can easily tab through HTML checkboxes on a website, but is there any way to make it so that on an iPhone when you hit the 'next' button it goes to a checkbox? I've noticed it'll go between text boxes and drop down menus, but it won't do it for checkboxes or clickable buttons. Is this an issue with the iPhone, or is it something I can change on my website?
Can you please be a bit more precise with your question. And if its the size of the checkbox that is a concern which makes it non tappable, then as suggested by the user interface guide of apple ios, please make the size as 44x44 to make it tappable. Well thats just a suggestible size and I believe a 25x25 size may solve your issue.

I have developed some app and want to add some manual for it. I mean, that there is button "Info" in the main menu of the app, so pushing this button, will appear that manual with text and images. I just need advice for the optimal solution, thanks.
I recommend using a UIWebView for this. It allows the simplest way to customize the view fully in terms of fonts, images, layout, etc. Just write an html file, add it to the project, and set it as the page for the UIWebView.
What can be used instead of tooltip in iphone app?
Best alternative of tooltip in touch screen systems?
Tooltips are generally reserved for operating systems that have a cursor. In touchscreen applications, tooltips should not be needed at all. When your application is in use, the user should always know where the menus are, what all of the buttons do, etc, simply because they have been labeled clearly with a text explanation or an image.
If you need the use of tooltips in your application, you need to rethink your design.
Be Succinct.
I believe tooltips are still viable in form of short timed message. For instance, you may show dialog when button can be single-clicked or long-pressed. How else would you describe to user that functionality. None of the solutions above seem to work in this case. I guess timed message, some kind of dialog and help file are only options. Or am I missing something?
You don't. Instead apply a stronger preference for text buttons over buttons with an icon. Sometimes a footer message describes the current status in more detail.
(this is just me, interpreting Apple app design as good practice)
Tooltips can be useful especially for icons or image that are not or cannot be labeled and also for multilingual apps where different text lengths must be taken into account. It's not always a question of rethinking your whole design, for me it depends on the context of your app. An design doesn't fail just because tooltips have to be added.
Safari on iPhone and iPad uses the method touch and hold on a link. This very near the actual hover and hold for desktop apps. This is also the direction we are looking at in my company.

Regards,
I am trying to build an app similar to USAToday i.e. each "article" is a mix of images and text that the user scrolls vertically to read if it covers more than than the size of the screen. Scrolling horizontally brings up the next article and so on.
Each article should have "paging enabled" so that the content moves as if you are turning a page in a book whether you are moving vertically or horizontally.
I must have looked at every tutorial for Scroll and Page navigation, but I am drawing a blank. Any help is much appreciated.
BTW: I have down loaded this tutorial....
http://www.edumobile.org/iphone/iphone-programming-tutorials/pagecontrol-example-in-iphone/
... but (a) it builds ok but simulator only shows a featureless black screen, and I cannot work out how to correct it, and (b) it only scrolls horizontally.
The sample code that you reference is old so I think something has changed in the SDK since then. I was able to at least get the code to run by changing the MainWindow.xib file. I opened that file in Interface Builder and then selected the Window and then in the Window Attributes Inspector I ticked "Visible at Launch". Then the tutorial would at least run and show the colors. I think you might find that there are more issues with it though.
When you are wanting to page something, the real trick is setting the content size of the scroll view.
This StackOverflow question has some good information that might help you get going.
I'm an iPhone developer, but new to web development. I've done some basic HTML websites and made one in iWeb as well. I'm trying to branch out to mobile web development now, so I checked out Dashcode.
Anyway, I'm trying to put a Call Button, Mail Button, and Map Button in horizontal alignment. I realize that I can add a Column Layout and have two buttons in a row, but that's the most I've gotten.
Any ideas? Thanks!

Edit: I still haven't figured this out yet. I was given advice about a fixed position button bar, but I am not sure how to implement it. I've been looking at code, but haven't gotten it yet. Still trying though. Any help is appreciated!
What i do usually is to select the element you can't align horizontally and then go to the inspector -> dimension tab and in disposition you select fixed absolute.
This should work but beware because if you've the intention to change element's place dynamically you may have some surprise...
I think you are looking for something like this.
A fixed position button bar is created with several buttons side by side.

I have a problem. Part of my app requires text to be shown in a table. The text needs to be selectable/copyable (but not editable) and any URLs within the text need to be highlighted and and when tapped allow me to take that URL and open my embedded browser.
I have seen a couple of solutions that solve one of either of these problems, but not both.
Solution 1: Icon Factory's IFTweetLabel
The first solution I tried was to use the IFTweetLabel class made possible by Icon Factory and used in Twitterrific.
While this solution allows for links (or anything you can find with a regex) to be detected to be handled on a case by case basis, it doesn't allow for selecting and copying.
There is also an issue where if a URL is long enough to be wrapped, the button that the class overlays above the URL to make it interactive cannot wrap and draws off screen, looking very odd.
Solution 2: Use IFTweetLabel and handle copy manually
The second thing I tried was to keep IFTweetLabel in place to handle the links, but to implement the copying using a long-tap gesture, like how the SMS app handles it. This was just about working, but it doesn't allow for arbitrary selection of text, the whole text is copied, or none is copied at all... Pretty black and white.
Solution 3: UITextView
My third attempt was to add a UITextView as a subview of the table cell.
The only thing that this doesn't solve is the fact that detected URLs cannot be handled by me. The text view uses UIApplication's openURL: method which quits my app and launched Safari.
Also, as the table view can get quite large, the number of UITextViews added as subviews cause a noticeable performance drag on scrolling throughout the table, especially on iPhone 3G era devices (because of the creation, layout, compositing whenever a cell is scrolled on screen, etc).
So my question to all you knowledgeable folk out there is: What can I do?
Would a UIWebView be the best option? Aside from a performance drag, I think a webview would solve all the above issues, and if I remember correctly, back in the 2.0 days, the Apple documentation actually recommended web views where text formatting / hyperlinks were required.
Can anyone think of a way to achieve this without a performance drag?
Many thanks in advance to everyone who can help.
As soon as I hit the submit button, a new idea hit me.
I was so preoccupied with having URLs inline with text and interactive that I didn't consider that maybe it's not the best solution.
I'm certain that to achieve that kind of behaviour, a UIWebView is the best choice, regardless of the performance issues.
However, maybe a better user experience / interaction is to not highlight the URLs inline, but to gather them into an array behind the scenes, and present a disclosure button as the cell's accessory view?
Then for selection and copying text, I could just use the UITextView with data detectors turned off and not worry about the links being sent off to safari and closing my app.
When the disclosure button is tapped, the user could be whisked off to the URL found in the text, or if more than one URL is found, present the user with a picker view to choose which to go to.
Any thoughts/criticisms of this idea are welcome.
You can prevent a textfield from being edited by overriding the UITextField Delegate methods such that they do not apply any edits. That leaves the field selectable and copyable but prevents alteration.
A better question to ask is: do you actually have to display the actual URL itself? Can you get away with just a page/location name, just the server.host.domain prefix or some other condensed representation of the url? I don't think anyone whats to try to read a long url on a mobile's restricted screen.
If you do need to display the entire url then I think that a detail view is the way to go.
