Hi, I am trying to move some custom drawing code from a view into a CAShapeLayer, which then get added as a sublayer to the original view's CALayer. This also works well, but when rotating the device, the animation starts to stutter, e.g. you just see the frame in the original orientation and then the final orientation, with at most one...
Hey guys I was just wondering how to make apps in two different languages? I think that I should create two files with all the variables in different languages each. Is that right? Help please Best Regards Carlos Vargas ...
So my simple idea is to create an app that allows the user to report their location's latitude and longitude coordinates via email. You tap the button, the email screen comes up via the MessageUI framework, the To, Subject, and Body fields are already pre-entered, all that's needed is for the user to hit "send". My problem, is that I n...
I'm tring to track a user touch moving across the screen, but at times my app receives touchesMoved:withEvent: with locations far apart, even by 70 pixels. I'm keeping the runloop fairly fluid, but I have CoreAnimation somewhat under pressure. I'm puzzled because I'm noticing the same problem even on the simulator. ...

I just want to figure out how to create vertical tab-based app like this one. Tab is generated dynamically when you push the add button. My guess is UIImageView(UIButton attached?) + UITableView as a set of component? But the whole tabs are scrollable. Any idea? Thanks in advance.

I have a UIViewController inside of a navigation based app. I'd like the view controller to receive all touch events from child objects, such as a tableview and navigation bar. Or, any other technique that is able to intercept all touch events. Right now, the following never executes inside of the view controller: - (void)touchesE...
Hi all, I'm confused about how to implement a specific piece of an app. The data is being collected in a Grouped Table, but certain rows drill down to another screen to allow the user to choose something. So for example, I would have Name: Surname: Age: How do I get this Age value back to the first view when the user taps done ? ...
Hi guys, first off, I'd like to say that this is my first time posting on StackOverflow. I'm new to iPhone dev and programming in general, having recently completed Stephen Kochan's Programming in Objective-C 2.0, and parts of Erica Sadun's iPhone Cookbook. Just reading answered questions on this site has helped me a lot, so I owe a big ...
I have an app with with a UITabController and each tab is a UINavigationController. The root of one of my UINavigationControllers is a UIViewController. Inside that view controller's view, I want to layout some subviews, but I'm confused as to where & how to lay them out in a way that will be resolution independent (i.e. not hardcode va...

Hi all, I have a modal view in my iPhone app (Xcode, Objective C++). How do I make it look as pretty as the system UIAlertView? Specifically, I want: rounded-rect window with a border around it semitransparent background subtle highlight near the top The transparency can be probably achieved with a less than one alpha channel on the...
UPDATE: I'm a doofus. What's happening is obvious. The Animation first sets the layers position to it's current position. But I've told the layer to divide any setPosition coordinates by pRatio. So it's not going to CGPoint(0,0) but something like CGPoint(0.032, 0). I've fixed it like this: - (void) setPosition:(CGPoint)point { if(!...
I have a subclass of UITableViewController that works as expected. I'd like to capture multitouch events for the whole table to do something with them. The way I understand it, I should make the tableView of the controller be a subclass of UITableView. In that class I could capture the touchesMoved etc events. But I also understand tha...
I came across a weird scenario in my code the other day: I have a UIImageView that loads an image with setImage:. The UIImageView is prior initialized with a frame having the exact size of the image (41*41 px). I also set the content mode to UIViewContentModeCenter, which should ensure my image is never scaled. Now when I look at my im...
I'm looking since quite a long time something like a CLLocationManager simulator that would enable me to simulate GPS positions (CLLocation instances that could be retrieved through the CLLocationManager standard delegate mechanism) along a predefined route for instance (with a KML or GPX file as input, or whatever, but KML would be ni...
