I am trying (and failing) to change the navigation bar of the UIImagePickerController .
self.pickerController.navigationBar = myCustomBar;
doesn't work, since navigationBar is readonly.
I still want to change the buttons (and colors) on the default "cameraControls" bar.
Do you know of any way to do that?
Thanks!
=============
Ok.. Thanks for the quick answers! So let me detail a little bit here...
For my application I only need the camera feed, and then I want to add my own buttons to a controls bar. I am not interested in photos (not yet anyways). Do you think it's best that I drop the UIImagePicker and just search for something else?
Thanks a lot!
You should consider hiding the original camera controls using the showsCameraControls and set your own controls using a cameraOverlayView. Both are properties of UIImagePickerController.
You might try searching the subview tree of the UIImagePickerController, finding the camera controls bar and hiding that. Then add a new subview with your controls to replace it.

Take a look at this picture:
I have something like a toolbar includes some buttons. user can move to left and right as you see. I know how to set the button in toolbar, but I don't know how can I fix this kind of navigation on the toolbar. Is it possible in the toolbar?
If yes, how?
if no, do you know any control in iOS that can help me?
It might be worth browsing through Cocoa Controls. They really have a lot of excellent pre-made custom controls for iOS and the Mac.
Personally, I would just create my own custom UIScrollView subclass which contains some UIButtons. Then set the scrollview to scrollView.pagingEnabled = YES after setting a correct content size.
Apple has an excellent guide on using scrollviews with paging here:
http://developer.apple.com/library/ios/#DOCUMENTATION/WindowsViews/Conceptual/UIScrollView_pg/ScrollViewPagingMode/ScrollViewPagingMode.html
Safari has a nice popover that is used for controlling the font size. I'm talking about that one:
It's pretty nice, and my question is - how to implement something exactly like this?
Thank you!
There are many projects in github about popoverview, such as this https://github.com/takashisite/TSPopover
One way to implement this is to add a transparent view that takes up the whole screen so that when I touch outside the popover content, it'll dismiss. And the rest you need to do is just add some subviews to your transparent view.
Simple Really, If you want to use a popover then you can see this code PopOver Link
Or you can simply create a UIView containing 2 buttons , let this UIView rollout an animation whenever the UIButton on the bar is clicked and so on and so forth. Let me know for further queries :)
Is there a way i can remove the border from my UIPopOver ?
Thanks,
UIPopoverController provides just about no method to customize its appearance. On the other hand, its behavior isn't hard to replicate, in the context you seem to be talking about—just create whatever view controller you're currently using in a popover and manually add its view to your view hierarchy.
As far as I can tell, there is no way to customize the look of a UIPopoverController. You can change where it appears. At the moment however, you cannot change the color or size of the boarder.
I am doing a lot of researching lately about how to get a different looking with nice effects UITabBar on my iPhone app, but unfortunately I am only finding things on how to replace background color etc.
Well, I've checked out this app called Momento which is pretty cool and presents a very slick tabBar:
So there are a couple of elements here I would like to ask you guys if you could help me by giving me the right directions on how to get a similar effect :)
Arrow above items: as you can see this app has this animated arrow that runs above the selected item with a very smooth animation.
Selected Stated of the item's image is not that blue-ish default one neither the default state which displays in a different shade of brown and gray version.
nice Items separators with beveled vertical lines.
different background image for the tabBar
different height for the tabBar
At this point after some research I am able to set the height and background image by subclassing UITabBarController but I'm still not sure on how to accomplish the other items specially the first one related to the nice arrow effect.
How do I do this? Please clarify what can or can't be done by subclassing the UITabBarController and specially if can be done in Interface Builder.
There's a project on github called BCTabBarController that aims to mimic the tab bar used in Twitter for iPhone. It's got some of the things you're looking for, and should give a great starting point.
Both of these are good answers, but both libraries have problems: BCTabBarController doesn't know how to create the "blue" highlighted version of a tab bar icon; and iDevRecipies doesn't send events to child viewcontrollers nor resize the navigation bar on rotate.
Be warned: custom nav bars are a lot of trial-and-error debugging (as I have found).
Simply use a UIView with TabBar width and height.Add custom background image and custom buttons on the view.Set the fileowner of the view as AppDelegate.Now you can simply connect the IBActions with the buttons.The Custom view can be placed over the tabbar by addSubView to the TabBar controller's view.You can switch between viewcontrollers by using the setSelectedIndex method of tableviewcontroller in the button action.
Can someone please tell me how to get a full screen image preview view when someone taps on an image view of a nib... like the one in appstore application screenshots....
it will be a real help...
Thanks in advance
The first thing you need to do is subclass UIImageView.
Then in your subclass make sure that user interaction is enabled (either by setting it in code, or by checking the box in IB).
Then you need to override the touches:DidBeginWithEvent: (et al) methods (they're found in UIResponder), and put the code for what you want to happen inside them. For example, you could create a larger image view, and then attach it to the view hierarchy.
As for making it completely fullscreen, you'd need to set the frame of the image view to that of the Window, and hide any Tab Bars, Navigation Bars, Status bars, etc.
You can hide the status bar by using
[[UIApplication sharedApplication] setStatusBarHidde:YES];
Hide navigation bars:
[navigationController setNavigationBarHidden:YES];
so on and so forth. You should be able to find ways to hide most things by looking at their docs.
Hope this helps.
I actually wanted a control like the image preview in photos and that on facebook maybe....
which i found in the open source three20 repository... google it to find out ....
