Hi all, I succesfully implemented a UIPickerView. However, I have a problem in selecting values. According to the standard way, I have implemented the method - (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component { // method implementation... } The problem is when I try to sel...
I've spent too much time walking down dead ends on this project, so it's time to query the hive mind: I am making a simple iPad game consisting of three locations which the user navigates between when an area of the screen is touched. These locations are represented by fullscreen images and there are a lot of different animations and st...
I am currently using the following code to write a CGContext to a PNG on disk: CGImageRef image = CGBitmapContextCreateImage(context); UIImage *myImage = [UIImage imageWithCGImage:image]; NSData *data = UIImagePNGRepresentation(myImage); [data writeToFile:path atomically:YES]; I found that the orientation of the resultant file is flip...

I have the following situation: A UIScrollView contains a UIWebView. I want the content inside the web view to be touchable, but the scroll view should not scroll unless it was touched near the left or right edge. I have subclassed both UIScrollView and UIWebView to try to override methods like hitTest and pointInside but no go so far. ...
In my iPad app, I have an implementation of a login window as a UIAlertView subclass that adds two UITextField, using an idiom that's found on the net. The problem is that in horizontal orientation, the alert is partially hidden by the keyboard. Namely, the buttons are hidden. Of course, it's possible to hide the keyboard to reveal the ...

Hi, I want to store the content of some variables in a file. The user nor the application should change the value. It would be great if the user cannot read the content of this file. On startup the application reads the file and initialize some (global?) variables with the content. The file should contain some values like server URL an...

My client's design calls for a table with cell content on irregularly-shaped white areas--basically a rectangle with a "tail". I'm constructing that out of a UIView and a transparent UIImageView holding the "tail" part of the design. It looks nice, with one exception. When I select a cell, the whole thing turns blue EXCEPT the UIImages....
Hi there, I use the following code to trigger image downloads in visible cells/paths: - (void)loadImagesForOnScreenrows { NSArray *visiblePaths = [tableView indexPathsForVisibleRows]; for (NSIndexPath *indexPath in visiblePaths) { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; if([cell viewWithT...
I have a universal iPhone / iPad application that I'd like to have support multitasking. On a multitasking OS, when my application goes to the background and then returns to the foreground, all I see is a black screen. What could be causing this and how do you suggest I work around it? ...
Am I correct in assuming using a UIWebView is the only/best way to integrate Google Checkout into an iOS App? A fully native solution would be the best fit as I only require the user to purchase a limited number of items that will never change. Does any one know of existing Apps that have successfully integrated Google Checkout? ...
I've found a question on this already but it didn't have a complete answer to it. Is there a Framework or Library that can do Syntax Highlighting in a UITextView, specifically syntax highlighting (and detection) for Objective-C on the iPhone. Some of my Ideas of how to do this: NSAttrbutedString. Now available in iOS 3.2 and greater...
Hello friends. I'm looking for a mechanism to add and read app-wide data, something similar to Web.config under .NET. I'm thinking of creating an AppConfig.plist, and in there I'll store URLs to web services, etc. so that these values can be read and used throughout the app. Is this an effective way to achieve what I'm after? Do you g...
Is there a way in the Address Book API to access the current user's record programatically? In other words, if this iPhone belongs to John Smith, to get the contact record that is John Smith (whichever record is marked as Me in Contacts)? Obviously you can popup the picker and let the user select themselves from their Contacts, but th...
I have the following code to draw a custom picker. Unfortunately when the view is first drawn is black. Only when I touch it does it appear. How can I fix this? Here is the relevant code in the UIView: - (void)drawRect:(CGRect)rect { [self createPicker]; [self addSubview:dPicker]; //[dPicker reloadComponent:1]; } -(void) cr...
My settings bundle specifies a Multi-Value element of type PSMultiValueSpecifier exactly as described by Apple here. I have all the required Keys entered, as well as the Titles array matching the values array in size. The default value is an integer, and matches a value in the values array (so no problems there). My issue is a usabili...
