I'm working with Xcode doing a Ipad app.
i simply want user to click anywhere on screen (not counting text fields) to perform some IBAction.I'm using an invisible button that covers my whole view.
Since I have some text fields in my view,i need to add this invisible button to the background of my user interface. I cant seem to find this option in the button attributes? any help?
Just set the button's type to custom.
Did you try setting the opacity of the button to zero?
I guess i got your point. You just want to put the UIButton(invisible) on the back of all the UITextField. The simple solution to this is open the Document Window in the IB. Now expand the view tree in the list view. Just drag your UIButton above the UITextFields and set the alpha value for the button in the property to be zero.
Hope this helps!!
iPad users don't "click". They "tap" or "touch".
In Interface Builder, I believe views are constructed with a z-index from top to bottom as they appear in the document window, so dragging your button so that it appears as the first subview of your main view should be a quick fix for this.
Have you considered other approaches? This doesn't sound like standard behaviour for an app and will probably cause havoc with anybody using Voice Over. What are you trying to accomplish?

In my Xcode project, I have a few buttons in the main window that I would like to replace with another type of button. In this case, there are a few rectangles and a rounded rectangle button. Is there an easy way to replace the buttons with another style, or am I stuck with deleting them and settings them all up again? Thanks in advance!
You can select button type custom and use your own special background as the button in Interface Builder.
If you want to further customize your button, I suggest making an outlet of it and customize it programmatically.
Good Luck!
I have created a forum with a View, and in the View I have placed a Text Field. My problem is, whenever I slide up they keyboard the text from the tableView are placed over the UIView and the TextField being covered. Any Idea what the reason behind this might be? While we are at it, maybe I shouldnt create a View with a TextField and instead use the standard look in iPhone sms apps, but I dont know how they created that bar. Any Ideas? I post all pictures below:
iPhone standard look, how to create something like this?:
My View with the text field:
My problem as i described above:
You can create a custom view for that and add it as an inputAccessoryView of the keyboard.
For more details please check apple documentation on this. When the keyboard is dismissed, show this view at bottom of the screen and when keyboard appears remove it from bottom and make it as inputAccessoryView.

The custom accessory view to display when the text view becomes the

I am making an app. It is kind of a hide and go seek. I was thinking about sectioning off separate areas and having the app say something different as to where you touched the screen. It will give you clues to where on the screen you need to touch next. So, these are my questions:
What is the easiest way? Would I want to make a grid of roundrectbuttons-placing each one and making an outlet for each - or can I make grid of buttons some other on the screen.If I place each button I will have a 9x12 of buttons making 108 buttons. Then I need to have a way to choose a random button as to where the location of the thing is question is. Would I use buttons at all or is there an easier way?
108 buttons is far too many to place in a xib :) If you wanted to use buttons then I would create them programatically in viewDidLoad in your controller.
Hoewever, I wouldn't use buttons at all!
I would use a TapGestureRecognizer attached to your background view. When you recieve a tap, take a look at where it was (use locationInView:self.view) and use that to work out what to do with the press.
I'm working on a iPhone app which shows an mobile webform in a UIWebView. I'm using a default iOS layout with a navigation and tab bar.
The mobile webform is displayed in a UIWebView in the white area. Since the webform has a lot of input fields, we really need as must space for it as possible. Because of this, we are planing to remove the tabs in the bottom. Over time, there will be more tabs/sections, so it is not a solution to just add a button for each section in the left side of the navigation bar. On a iPad a popover could easily be used to handle this.
Is there a standard iOS layout mechanism to handle this change of sections/views without using tabs?
You could do something long the lines of Path or the new Facebook app and have the "table of contents" behind the Navbar and the navbar slides away (along with the child view) to reveal it. When done right (ie smoothly) I think the effect is really cool.
This would also work great as you add more and more options, since the table could just scroll.
Here is a framework that might be you started: http://www.cocoacontrols.com/platforms/ios/controls/iiviewdeckcontroller
I would consider replacing the navigation bar's title with a control that lets you switch between tabs. You can assign the bar's titleView property to a control or a button and it will generally do the right thing.
If you're limited to 2-3 tabs, you could simply use a UISegmentedControl.
If you want more, you could use a button which, when tapped, pops up a view that allows you to select the view you want. This could be a modal table view, or you could slide up a UIPickerView from the bottom of the screen, similar to the keyboard.
I use this technique in an app of my own, screenshots here. Tapping the button cycles between views (in this case, I'm changing the contents of the table cells); tap-and-hold slides up a picker.
Another possibility would be to arrange your different forms on pages in a scroll view with a page control at the bottom, à la Weather. The best option, though, if you’re going to have a particularly long list and want to keep your screen real estate, is probably the FB/Path-style sidebar table.
I ended up using a UIActionSheet but I think it in other situations would be more stylish to use a controller like the IIViewDeckController.
This is hard for me to explain, so please bear with me for a minute.
In Xcode, if it is in full screen mode, showing the app's menu also moves the toolbar down. I have tried to make an NSView move and resize whenever the menu bar is shown, but I cannot figure out how to do it. I think this has something to do with and event, because setting struts and springs in Xcode does not make it move automatically. Can anybody help me figure out what the event is?
Edit: I just re-thought my question, and I have to make a correction. NSToolbar does this on it's own. I want a normal NSView to move and resize itself when the window goes into full screen mode.
I think you might be having the same issue as I was - if so, you need to call [NSToolbar setFullScreenAccessoryView:] on the "accessory view" you want to glue to the bottom of the NSToolbar.
Note that in windowed mode, your accessory view should take up space in the NSWindow's contentView just like any other view, but when you enter fullscreen mode you'll want to remove the accessory view somehow since Cocoa rips it out of your layout and leaves a gap unless you account for that.
I can certainly understand this issue being difficult to explain without having the background knowledge - I had the same problem. :)
