I need to display a table formatted data on top of a UIWebView as a modal. Basically a UIAlertView. However, I need to display tabular data in this modal, which UIAlertView can't do (that I know of). I'm thinking to create an image with the textual data in it and display the image in a UIImageView or that within a UIView that can have a button for closing. Not sure if that can all be made modal.
I see a view can be added as a subview to UIAlertView: http://blogs.oreilly.com/iphone/2008/03/open-iphone-sdk-building-a-uip.html. Not sure if Apple will go for that though.
Do these approaches sound feasible or is there a better way?
there is a very simple way add a table and a uiwebview in a view. set the datasource and delegate of the table.and show the data. or if you want something else...show a picture or explain in more detail.

I am building an app that requires a tableview control so that users can select multiple rows and act upon them in some way. I find it easy to load my data and display it using the UITableViewController but it seems when I do it this way I am unable to place any other controls on the page, such as a toolbar to give the user some actions to perform on the selected rows. I can place a toolbar control on the form in the storyboard, but it doesn't render in the emulator.
Using a UIViewController and placing a TableView on it seems to come with its own set of confusing challenges (that will make total sense once I conquer them).
Is there any advice for a smooth way of getting a table view with toolbar controls? Thanks!
don't use a TableViewController. Use a Standard ViewController, then add a UITableView to it, and adjust the size. This way you will be able to do whatever else you want on that view without limiting yourself to the tableView only functionality.
When you do this make sure you add the datasource and delegate to the connected table. Then add cellForRowAtIndex, number of sections, number of rows, and whatever other delegate methods you need for your table.
Good luck
Is there any advice for a smooth way of getting a table view with toolbar controls?
Yes there are few ways to accomplish this, one way would be adding a footerview to your tableviewcontroller check these
http://developer.apple.com/
UIButtons on tableFooterView not responding to events
Easier way to add this is using storyboard.
Just drag and drop a view in to your tableviewcontroller, then you can adjust the views size and put anything from objects menu to inside of the view.
Now the problem with that is view will not be stable position at the bottom of the page like a tabbar. Lets say you have only 1 row in your tableview, footer view will go up just below that 1 row, lets say you have hundreds of items in your tableview toolbar will be at the bottom of the rows.
The other solutions for your problem would be either create a custom view and adding it to current view or window (this is little bit adbance),but if you want this just google it.
Or just as you said, create a viewcontroller and put a uitableview inside. Dont forget to add <UITableViewDelegate,UITableViewDataSource> to your .h file and then you can call UItableview delegate methods.\
Good Luck.
I want to display like 9 thumbnail (arranged in 3x3) images in a View Controller.
Then when I touched on one of the thumbnail images, it loads another View Controller,
to display the details of this specific image, like date taken, description of the photo.
I have checked out Three20 project, but im not sure if this is the only way to go?
Are there other ways to do this without using the Three20 project?
Thanks!
There are many ways to do that.
the simplest ways I can think of are:
create a view that holds 9 UIImages and add a gesture recognizer to the views, create a view to hold the deatils and call it each time a view is clicked.
create 9 buttons and set the images to the buttons, reate a view to hold the deatils and call it each time a button is clicked.
pretty strait forward.
good luck

I am working on an app which displays user information on the home view. Its a regular tab bar application, which brings up the home view on load. I need to display something like,
Hello Joe,
Your current points are : xxx
I would like this to be in a white curved background box. (The background for the view is blue). Is there something like a UIPanel or something like that. I would really like to avoid having another view or a webView, not sure if thats going to affect the speed of loading the page.
If there were a UIPanel control it would derive from UIView, so I'm not sure why you want to avoid another view. If I'm understanding you, it sounds like you want a custom alert window of some sort. You could just use the UIAlertView control to display your message, but if you are dead set on a custom look, then you will need to use a view.
This shouldn't affect performance noticeably if you are just displaying some text with maybe a button on a custom image. Especially if this is just a tab bar application with nothing too crazy happening in the background (animations, etc.).
I would suggest creating a View either in code (this will be slightly faster, but once again probably not noticeably so) or with Interface Builder that has a black background with an opacity of like .2-.5 and on that view adding a UIImageView set to your custom image (a png of a white curved box with transparent corners). Then put a UILabel with your text and a button to dismiss it.
On load just instantiate the above view and add it to your current view. It will show your message modally. Then capture the button tap event to have it remove itself from it's superview.
There are plenty of examples of how to do exactly this out there and there are even other ways of doing it than what I've suggested. If you need further assistance let me know.
I am almost at the end of coding my kids educational application, woohoo!.
But... Im stuck on something.
When app loads i have my main view. It has 4 buttons for flipviews(each with ten views of content) and 4 buttons for character selection(an image that will follow you through every screen of content).
Problem is im unsure on how to link UIButton selection to UIImage display in multiple views. I want the user to choose a character button and then continue to the flipviews and in the views the image displayed should be the one that they have selected on the main view. So everytime they return to the main view they can change the character that will follow them around the app.
Any thoughts, help or code would be much appreciated!
Thank You

Make a new object, a subclass of UIImageView, which has a -setImage method. Once you set the image, then where ever you embed that object, it will display the same image. You could even have that subclass view have a score displayed next to it, or a name or other stats, so as you go from one screen to another, you have all that info follow you around with the image. No need to create labels in all the screens for global info like that.
In summary:
make a new subclass of UIView or UIImageView in Xcode using the New File... menu. You would do new UIView if you will have other items than just an image.
add methods that allow you to set the image, update text stats etc.
BONUS: you can make the class handle taps, so if a user taps the image, you could do something like provide help or run a cute little animation
embed that object in any screens you wish. Keep in mind that you can have that view be sized differently in each screen using transforms. Cool, no?
that's pretty much it!
Good luck!
I'm trying to create a modal status indicator display for an iPhone app, and would like one similar to this one used in Tweetie:
Specifically, this one "shades out" the entire screen, including the toolbar. I don't believe through any normal UIView manipulation, I can extend past the bounds of my window, can I? I believe I've seen a status indicator like this somewhere else on iPhone, possibly when I added an Exchange e-mail account.
I've tried subclassing UIAlertView and overriding its drawRect method. If I don't call [super drawRect:] it doesn't ever display the normal UIAlertView text box, however my drawing rectangle is in an odd size and position.
Anyone have any advice to accomplish this?
Check out MBProgressHUD.
Take a look at the source code to the WordPress application. They have code which you can basically drag and drop into your application to do this.

I haven't done this myself, but you could layer a UIView at the top of the view hierarchy, and use setHidden to dynamically show or hide it. Since it's at the top of the stack, it should be able to intercept all touch events.
