Is there a way to control the position of the auto correct view that pops up while typing in a UITextField? By default it appears to always appear below the text field. However in Apple's apps like SMS it sometimes appears above the text field. For text fields aligned right above the keyboard the auto correct is blocked by the keyboar...
I have an outline view with 2 entities being displayed inside it so It is connected to a NSTreeController. I have created a button and binded it to the NSTreeController's Controller Key 'canRemove' under Availability>Enabled. But when you run the App the button is always Disabled even when a row is selected in the Outline View. How can t...
I have a large number of UIViews that are created in the app delegate applicationDidFinishLaunching and added to an NSMutableArray. The user pages through these views using a page control and scroll view. I created the UIView and its child components in IB. They are wired to a controller. To create 170 views on the iPhone takes about...

Example: I have 10 view controllers, which are all allocated and initialized in the same way: UIViewController *controller = [[MyViewController alloc] initWithNib]; (note that -initWithNib is a custom method of a UIViewController subclass) The next view controller class is OtherViewController, and so on. I want to load the view cont...
Here's a simplification: I have an application with several buttons. If it is the first time the application is launching, I want to do some special things. In my AppController class, which is a delegate of NSApp, I use the delegate method -applicationDidFinishLaunching: to perform the test. After I've detected that it is the first t...
I have a class XMLParser. It works fine as long as I don't remove the commenting of the line that adds the nodes to the NSMutableArray: [nodes addObject:self.currentNode]; If I do that, the application crashes - without leaving any trace in the debug log. How can this be? XMLParser.m: #import "XMLParser.h" #import "MyViewController....
I would like to my object to receive notification with the DeviceToken becomes available. Is there a way to delegate only certain functions from the UIApplication to my class? Update: I'm not so much interested in accessing it from the application delegate, I already have an application delegate, but want to respond to the event via c...
I could not find a post exactly like this, so please forgive me if this is a duplicate. I am trying to write text using a Core Graphics context. I can do it the first time, no problem, but the second time crashes my iPhone app. Here is a code snippet: NSString *name = [MyClass getName]; const char *cname = [name UTF8String]; [self dr...
Before I ask my questions, this is from Apple's documentation re: how to determine the width of a string using Quartz: If text measurements are important to your application, it is possible to calculate them using Quartz 2D functions. However, you might first consider using ATSUI, whose strength is in text layout and measurement. ATSU...
I'm doing usability testing and would like to log all user input events: mouse movements, clicks, drags, and keyboard input. I'm not having much luck figuring out how, or finding any code to do so. Any hints? I took a look at the CoreGraphics EventTap mechanisms, but I'm worried that it will be too low-level; I'd like to actually know wh...

I have already located the iPhoto SDK for Exporting but cannot get my head around how to change the destination to a web site/service and the process involved.

Hello- I have searched all over for this, but I can't seem to find the best approach to this. I have about 22000 lat/lon points and I want to find the closest one's to the current location of the iPhone. I've seen people ask about Quad Trees, Dijkstra's Algorithm, and spatial databases. Which is the best for the iPhone? Spatial databases...
So I tried to use the Quartz CGImageCreateWithMaskingColors function, but he only problem is that it masks the color range you are selecting. I want to mask everything but the color range I am selecting. For instance, I want to show all red colors in a picture but remove the other channels (Green and Blue). I am doing this in Objecti...

I've just been bitten by an annoying bug that was made obscure by the "send message to nil is ok" behaviour in Objective-C. I've seen http://stackoverflow.com/questions/156395/sending-a-message-to-nil, and the consensus seems to be 'thats how we roll' in Objective-C. Now, maybe I don't have enough experience in Objective-C, but it seem...

I have a project that targets both Mac OS X 10.4 and 10.5, where 10.5 is the base SDK. Some methods like -[NSString stringByReplacingOccurrencesOfString:withString] are unavailable in 10.4. I could just implement the functionality by hand. Another option would be to implement the method as a category, but that would mess with the 10.5 i...
