  • change the class loading order google app engine java

    - by Shekhar
    I am trying to create an application on google app engine using struts2. Struts2 internally uses freemarker .One of the Freemarker framework classes suppose X internally uses a class javax.swing.Treenode which is not in google app engine jre white list. Now in order to run my application i created a new class X in the same package structure as it was in freemarker framework and copied the class to WEB-INF classes.Then When i run my application it run fine. The problem is that i want to take out the class X from my application sourcecode and move it to newly created jar and place it in WEB-INF/lib folder. So that i can reuse the code in multiple project and my code remains clean of the freemarker code. But when i run the application it picks the old class X from the original freemarker framework.As a result i get ClassNotFoundException. Can anyone provide any help such that i can change the ClassLoading order such that my jar containing X class loads first.

  • Setting ViewController delegates in iPhone runtime

    - by Stein Rune Risa
    I am writing an iPhone application and needed to use the address book functionality. For this to work, it is necessary to specify a ABPeoplePickerNavigationControllerDelegate on the ViewController. The problem is that I am creating all fields and buttons dynamically runtime, and thus does not have any custom ViewController - using only UIViewController class. My question is then - how can I specify the delegate runtime without having to create a ViewController class just for this purpose.

  • OpenGL ES view: how to orient it to landscape?

    - by Steph Thirion
    Looking for clues about orienting an OpenGL ES app in landscape, most information I found dates back from 2008, most of it refering to the early versions of the SDK. Apparently, back in the days, in the case of GL it was recommended to not rotate the view, but instead to apply the rotation as a GL transformation. Is it still the case with the current SDKs? It would be so much simpler to simply rotate the window: all the touch events would be in sync with the rotation. In other words: how to set up an OpenGL view in landscape mode?

  • iPhone app: recover view after didReceiveMemoryWarning

    - by mga
    The app in question has a MainView->ModalView pair. The ModalView is shown via UIModalTransitionStyleFlipHorizontal. In case of didReceiveMemoryWarning, MainView is dumped (since it is not visible) and the app stays "alive" but when you flip back there is a (very) short period of time when the screen is blank (since the modal dialog is returning to a now-deallocated view). When the animation transition is over, MainView is regenerated and all is ok. I just would like to somehow regenerate MainView before returning from ModalView (in case of a memory warning). Is this a good idea? Am I doing something wrong as far as the warning is concerned? Thanks

  • Storing secret keys on iPhone source and project resources

    - by hgpc
    Is storing secret keys (internal use passwords and such) on iPhone source code and project resources (such as plist files) secure? Obviously nothing is 100% secure, but can this information be extracted easily from an installed app? How do you recommend storing these keys to use them in the source code? Just in case, this question is not about storing user passwords.

  • Turn off iPhone/Safari input element rounding

    - by Alex
    My website renders well on the iPhone/Safari browser, with one exception: My text input fields have a weird rounded style which doesn't look good at all with the rest of my website. Is there a way to instruct Safari (via CSS or metadata) not to round the input fields and render them rectangular as intended?

  • How to start a major iPhone app update in Xcode

    - by Eric
    I have an app in the iPhone app store and have released several minor updates to it. I want to begin work on some major feature additions and reorganization, but don't want to lose the source code of my most recent version in case everything goes horribly wrong. Should I start a new Xcode project from scratch and copy my existing source in? If I do this will I be able to submit the build from this new project as an update or will Apple complain that the build comes from a different Xcode project? I've seen (but not used) Xcode's "Snapshots" and "Source Control" features - are these what I'm looking for? Any help or direction greatly appreciated.

  • NSFetchedResultsController titleForHeaderInSection with formatted NSDate

    - by Daniel Granger
    In my Core Data app I am using a FetchedResultsController. Usually to set titles for headers in a UITableView you would implement the following method like so: - (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { id <NSFetchedResultsSectionInfo> sectionInfo = [[<#Fetched results controller#> sections] objectAtIndex:section]; return [sectionInfo name]; } where [sectionInfo name] returns a NSString. my sectionKeyPath is based on an NSDate and this all works fine apart from the section headers it gives me are the raw date description strings (e.g. 12/12/2009 12:32:32 +0100) which look a bit of a mess in a header! So I want to use a date formatter on this to make a nice header like "Apr 17 2010" but I can't do that with the [sectionInfo name] as this is NSString! Any Ideas? Many Thanks

  • iPhone: didSelectRowAtIndexPath not invoked

    - by soletan
    Hi, I know this issue being mentioned before, but resolutions there didn't apply. I'm having a UINavigationController with an embedded UITableViewController set up using IB. In IB the UITableView's delegate and dataSource are both set to my derivation of UITableViewController. This class has been added using XCode's templates for UITableViewController classes. There is no custom UITableViewCell and the table view is using default plain style with single title, only. Well, in simulator the list is rendered properly, with two elements provided by dataSource, so dataSource is linked properly. If I remove the outlet link for dataSource in IB, an empty table is rendered instead. As soon as I tap on one of these two items, it is flashing blue and the GDB encounters interruption in __forwarding__ in scope of a UITableView::_selectRowAtIndexPath. It's not reaching breakpoint set in my non-empty method didSelectRowIndexPath. I checked the arguments and method's name to exclude typos resulting in different selector. I recently didn't succeed in whether delegate is set properly, but as it is set equivalently to dataSource which is getting two elements from the same class, I expect it to be set properly. So, what's wrong? I'm running iPhone/iPad SDK 3.1.2 ... but tried with iPhone SDK 3.1 in simulator as well. EDIT: This is the code of my UITableViewController derivation: #import "LocalBrowserListController.h" #import "InstrumentDescriptor.h" @implementation LocalBrowserListController - (void)viewDidLoad { [super viewDidLoad]; [self listLocalInstruments]; } - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; } - (void)viewDidUnload { [super viewDidUnload]; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [entries count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; if ( ( [entries count] > 0 ) && ( [indexPath length] > 0 ) ) cell.textLabel.text = [[[entries objectAtIndex:[indexPath indexAtPosition:[indexPath length] - 1]] label] retain]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { if ( ( [entries count] > 0 ) && ( [indexPath length] > 0 ) ) { ... } } - (void)dealloc { [super dealloc]; } - (void) listLocalInstruments { NSMutableArray *result = [NSMutableArray arrayWithCapacity:10]; [result addObject:[InstrumentDescriptor descriptorOn:[[NSBundle mainBundle] pathForResource:@"example" ofType:@"idl"] withLabel:@"Default 1"]]; [result addObject:[InstrumentDescriptor descriptorOn:[[NSBundle mainBundle] pathForResource:@"example" ofType:@"xml"] withLabel:@"Default 2"]]; [entries release]; entries = [[NSArray alloc] initWithArray:result]; } @end
