I have the ISOCountryCode avaliable and now i want to derive the currencyCode of this country from the ISOCountryCode. How can i achieve that? NSString *countryCode = < get from someother view>; NSString *currencyCode = ?; I receive this country code from some other view on runtime? You will need to use NSLocale. To retrieve the currency code from a specific country code: NSString *countryCode = @"US"; NSDictionary *components = [NSDictionary dictionaryWithObject:countryCode forKey:NSLocaleCountryCode]; NSString *localeIdent = [NSLocale localeIdentifierFromComponents:components]; NSLocale

When the keyboard appears, I want to set the keyboardAppearance = UIKeyboardAppearanceAlert I've checked the documentation and it looks like you can only change the keyboardType. Can this be done without violating any of Apple's private API's ? Erich Wood The best way that I found to do this, if you want to do it throughout your app, is to use Appearance on UITextField. Put this in your AppDelegate on launch. [[UITextField appearance] setKeyboardAppearance:UIKeyboardAppearanceDark]; This should do it: for(UIView *subView in searchBar.subviews) if([subView isKindOfClass: [UITextField class]]) [

I have a UITableView with style "Grouped" which I use to set some options in my App. I'd like for one of the cells of this UITableView to only show up depending on whether another of this UITableView's cells is activated or not. If it's not, the first cell should show up (preferably with a smooth animation), if it is, the first cell should hide. I tried returning nil in the appropriate -tableView:cellForRowAtIndexPath: to hide the cell, but that doesn't work and instead throws an exception. I'm currently stuck and out of ideas how to solve this, so I hope some of you can point me in the right

I'm using a UITableViewCell with UITableViewCellStyleSubtitle. However, because of the background image I'm using for the cell, I don't like where the detailTextLabel is going. I want to move it and resize it within the cell, but nothing I try seems to work. CGRect currRect = cell.detailTextLabel.frame; cell.detailTextLabel.frame = CGRectMake(currRect.origin.x + 20, currRect.origin.y, currRect.size.width - 40, currRect.size.height); I tried putting this code into both tableView:cellForRowAtIndexPath and tableView:willDisplayCell:forRowAtIndexPath methods, but neither works. The label simply

I downloaded a project developed by Apple employees ( who taught course at Stanford on iPhone application development). Strangely , the frameworks are red. http://img.skitch.com/20100730-kcjun96mp2pxnpg7w3x6njw57.jpg I tried to locate coreGraphics.framework and UIKit.framework to add them again but i couldnt find them either. Taimur The red text indicates that the actual files are not at the path that the project has for them. Get info on the framework and look under the General tab. The first section shows the name and path of the framework bundle itself. The most common cause of a problem

I know a similar question has been asked before but it seemed never been answered. I have a UIWebView and add some content by string. I use UIWebView because I add some images to it dynamically and also use other HTML features. This example code is simplified. NSString *myHtmlString = @"SOME LONG TEST STRING 1234567890 123456789 0123456789 0123456789 0123456789 01234567890 WWWWWWWWWW WWWWWWWWWW WWWYYYYYYY YYYYYYYYYY YYYYYYYYYY YYYYYYYYYY YYYYYYYYYY YYYYYYYYY YYYYYYYWWW WWWWWWWWWW WWWWWWWWWW WWWXXXXXXX XXXXXXXXXX XXXZZZZZZZ THIS IS THE END I WANT TO SEE"; NSString *myPath = [[NSBundle

While developing apps in Xcode memory leaks are occurring. When I checked them in extended detail view they are showing different methods that are not related to implemented. How to exactly find out which object is leaking and where it is leaking memory. When ARC is enabled we have to take care of memory leaks or not? Even with ARC memory leaks can occur, it just inserts release and autorelease during compile time. 1. You must check for leaks using Build and analyze in XCode, shift+command+b you should be clearing those issues. 2. After that you can start using the instruments by using profile
