The Keychain seems to be used a lot for usernames and passwords, but is it a good idea to use it for other sensitive stuff (bank details, ID numbers etc), but with no password? What kind of encryption does the keychain use? The scenario I'm concerned about is a thief acquiring an iPhone (which is screen-locked) and being able to access the file system to get this info.
Also, would using the Keychain involve export restrictions due to the use of encryption?
Hello.
I'm very new on iPhone development. I'm trying to draw a cross over the image obtained from camera.
I'm using a custom ViewController that inherits from UIImagePickerController.
When I star the application, I see the cross, but a few seconds after the cross disappears.
Should I use cameraOverlayView?
Thank you

I was wondering how I would go about creating a view that persists through all the over views and controllers in the application. Similarly to how Soundcloud does it with their music player in their iPhone app (See pic). No matter where you go in the application the music player view stays at the top below the toolbar.

Seems like UIDevice class does not provide anything like that.
Hey!
I am planning on developing an iPhone App for a website, powered by Wordpress.
Where can/should I start codewise when developing an app for such sites? Does Wordpress have an API, should I access the (MySQL) database directly, etc?
Thank you.
Hi Guys
I am try to make iPhone application to encode-decode an images (NSData format).
NSData imageData = UIImagePNGRepresentation(image);`
How can I do, please give some source code.
Thank you!
In my project I am trying to save video to the iPhone after being taken by the camera.
When I call the method:
UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(path)
It reports the error:
Implicit declaration of function 'UIVideoAtPathIsCompatibleWithSavedPhotosAlbum'
I've imported MobileCoreServices/UTCoreTypes.h
I was previously using this same code for saving camera pictures, and it worked fine.
In another class, in the same project, I am able to reference the UIKit method:
UIImagePNGRepresentation()
without any problems
So why does it give me this error?
Hi, I'm writing a POS application for the iPhone/iPod combination, using the same exact hardware used in Apple Stores:: EasyPay.
Ok, my hurdle is this: how do I identify which credit card type is being used as text is entered in the uitextfield?
I assume I've to use textField:shouldChangeCharactersInRange:replacementString:? However, I've got ideas floating around, but I simple cannot put them together to form code :/
Any help is appreciated!
Thanks in advanced :D
In the Linked in iphone application I noticed that they have a tableview, see the following picture with what appears to have a triangle indicator pointing upwards.
Notice how the tableview cell has a little triangle pointing upwards and is part of a tableview cell.
The triangle is the ---^--- part of the image.
I'm wondering. How do you make a UITableView with this triangle indicator, and what is this effect called?
Thanks

Hello guys!
I want to use the FileMerge utility on my mac, but it isn't installed. I searched in the google and there is written that it will be installed with the developer tools. So the big question is where can I find the developer tools, because I downloaded the iPhone SDK 3.2 beta 5, and installed it, but I can't found the download location of developer tools. Maybe can you help me?
Hi all,
On my iphone app, I have a UITableView in edit mode, containing custom UITableViewCell.
I would like to detect when user has clicked on the left button of each cell (minus circular red button, the one that is animated with a rotation), just before the "Delete" button appears.
I would like to be able to change my cell content in that case...
Is that possible ?
Thanks !
I'm trying to have standard interface orientation, but without the animation.
I would like to be able to turn the iPhone and have have the view adjusted instantly.
I've seen people recommend this function, but it doesn't seem to work.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return NO;
}
Any help is greatly appreciated!
Thanks!
I have integrated mobile analytics in my iPhone app with the help of the Flurry analytics but I am not able to track page views.
I have used the following code in my Application Delegate and passed an instance of UINavigationController in the place of navigationController
[FlurryAPI logAllPageViews:navigationController];
But while checking the Page views in the Flurry website it is showing the message like this:
You are not currently tracking Page View data.
Is there something that I have to enable in the flurry website itself?
I see NSInteger is used quite often and the typedef for it on the iPhone is a long, so technically I could use it when I am expect int(64) values. But should I be more explicit and use something like int64_t or long directly? What would be the downside of just using long?
