Hey I have these UIView objects in a dictionary I have created as such: - (NSArray *)createNumberOfViews:(NSInteger)number { NSMutableArray *viewArray = [NSMutableArray array]; for(NSInteger i = 0; i < number; i++) { UIView *view = [[UIView alloc] init]; // any setup you want to do would go here, e.g.: // view.backgroundColo...
I used Unity iPhone(1.7) to build an app and brought it into Xcode (3.2.3). When the game is built out, Unity creates an appController file automatically and in it, a window is created which displays the game. When I launch the game, I can clearly see when I rotate the device that the window is rotating as well. The game elements themsel...
[update: this problem has been resolved; the issue was not in drawInRect: but in UIGraphicsBeginImageContext()] In my app, I'm grabbing a bunch of large images, cropping them down to thumbnail size and storing the thumbnails for previewing. Note that I'm doing this in a separate image context -- this is not about redrawing a UIView th...
I want to call an action in two classes (a superview and a full screen subview) when the user single taps the screen. But, when I add a UITapGestureRecognizer to the subview, the one added to the superview is overridden.

The interface of my iPad app has multiple section boxes (looks similar to this stackoverflow page). I'm new to xcode and iOS programming but have years of web development experience. I would like to know what is the best way to design this. Should I put everything in one xib file? (section1headerlabel, section1text1,section1text2..) ...
Hello all, I am trying to include a C++ library with quite a few templates into an objective C application. It seems to perpetually choke on a few inline statements inside a shared library: template <class T> inline T MIN(T a, T b) { return a > b ? b : a; } template <class T> inline T MAX(T a, T b) { return a > b ? a : b; } yieldin...
I have a tableView with some large images in it. I'm struggling to improve the very jerky scrolling performance. If I use ImageNamed to load the images, scrolling is jerky at first, but after the images are viewed, scrolling is smooth. I know ImageNamed adds the images into the system cache, so my question is: is it possible to pre-load ...

Hi Guys I have a UIView and on it i have place a tableview, the tableview uses custom cells fed data from an NSArray. Some strangeness going on in that at most I can only ever get the table to display 2 cells even though there are 10 cells there and all 10 are populated.

To program for the iPhone, you need an iPhone. That's because you have to compile the final version of the app on the iPhone hardware. Do you also need an iPad when you program for the iPad? Or will an iPhone also do the job? ...
So, I'm pretty much a noob, and I'm pretty sure I'm missing something fundamental, but this is the last hurdle I need to overcome to finish my app. Basically, I have 2 custom classes, my custom ViewController, and something I'm just calling "Button" which is a camera overlay view with a segmented control on it. The segmented control has...

Hey guys, I have a tableview, and whenever I swipe a row in section A and after that select a row in section B, it thinks I selected the swiped row in section A! I placed a breakpoint to verify and am 100% sure that it thinks it's that cell AND that it calls it when I select the row in section B. By swipe I mean that you place your fi...
Hello, This is a very simple question. I have a script in the same folder as the Cocoa app. I can't seem to set the path to it properly for setLaunchPath for NSTask. Help please. I have a folder called Project. Inside of it, exist multiple folders but only two we care about: Classes (the source files for the Cocoa app are here) and Rub...
I read some examples of code necessary to make an application Applescript-able, but I still don't understand if the Apple codes used to identify a command, a class, a property can be any value I want (with the exception of the code for the application class), and if they must be registered in some site. Is there a list of codes with a p...

My app hit the app store today. I had a user submit a weird bug. I have a date picker that passes back a date that I store as a string in SQLite. I tested the app on the simulator, a 3G, a itouch, and an iPAD. On all of these, it works as expected. However, on this user's 3GS it adds a day to the date selected in the date picker. I...
