  • client-server syncing methodology [theoretical]

    - by Kenneth Ballenegger
    I'm in the progress of building an web-app that syncs with an iOS client. I'm currently tackling trying to figure out how to go about about syncing. I've come up with following two directions: I've got a fairly simple server web-app with a list of items. They are ordered by date modified and as such syncing the order does not matter. One direction I'm considering is to let the client deal with syncing. I've already got an API that lets the client get the data, as well as do certain actions on it, such as update, add or remove single items. I was considering: 1) on each sync asking the server for all items modified since the last successful sync and updating the local records based on what's returned by the server, and 2) building a persistent queue of create / remove / update requests on the client, and keeping them until confirmation by the server. The risk with this approach is that I'm basically asking each side to send changes to the other side, hoping it works smoothly, but risking a diversion at some point. This would probably be more bandwidth-efficient, though. The other direction I was considering was a more traditional model. I would have a "sync" process in which the client would send its whole list to the server (or a subset since last modified sync), the server would update the data on the server (by fixing conflicts by keeping the last modified item, and keeping deleted items with a deleted = 1 field), and the server would return an updated list of items (since last successful sync) which the client would then replace its data with. Thoughts?

    Cannot find executable for CFBundle/CFPlugIn 0x432bfa0 </Library/Audio/Plug-Ins/HAL/DVCPROHDAudio.plugin> (not loaded) Cannot find function pointer NewPlugIn for factory C5A4CE5B-0BB8-11D8-9D75-0003939615B6 in CFBundle/CFPlugIn 0x432bfa0 </Library/Audio/Plug-Ins/HAL/DVCPROHDAudio.plugin> (not loaded) That's the error I get when I try to run this code: NSString *path = [[NSBundle mainBundle] pathForResource:[arraySubFarts objectAtIndex:indexPath.row] ofType:@"mp3"]; NSURL *file = [[NSURL alloc] initFileURLWithPath:path]; AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:file error:nil]; self.player = player; [player prepareToPlay]; [player setDelegate:self]; [self.player play]; Any idea why? :S I have included the needed frameworks, and the code works great, the only thing is this odd Console-message..

  • Follow up viewDidUnload vs. dealloc question...

    - by entaroadun
    Clarification question as a follow up to: http://stackoverflow.com/questions/2261972/what-exactly-must-i-do-in-viewdidunload http://stackoverflow.com/questions/1158788/when-should-i-release-objects-in-voidviewdidunload-rather-than-in-dealloc So let's say there's a low memory error, and the view is hidden, and viewDidUnload is called. We do the release and nil dance. Later the entire view stack is not needed, so dealloc is called. Since I already have the release and nil stuff in viewDidUnload, I don't have it in dealloc. Perfect. But if there's no low memory error, viewDidUnload is never called. dealloc is called and since I don't have the release and nil stuff, there's a memory leak. In other words, will dealloc ever be called without viewDidUnload being called first? And the practical follow up to that is, if I alloc and set something in viewDidLoad, and I release it and set to nil in viewDidUnload, do I leave it out of dealloc, or do I do a defensive nil check in dealloc and release/nil it if it's not nil?

  • UITableViewCell color issues with custom table view background

    - by Macatomy
    I have a UITableView with a custom background image set like this: self.tableView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"mybg.png"]]; The background appears fine, but my UITableViewCells (default cells, not custom) have some sort of weird tint to them, and the UILabel containing the "New Project" text also seems to have some sort of background behind it. How can I remove this? I've already tried: cell.backgroundColor = [UIColor clearColor]; cell.textLabel.backgroundColor = [UIColor clearColor]; Thanks

  • NSString stringWithFormat

    - by Leo
    Hi Guys, I don't know what I am missing here. I am trying to concatenate strings using NSString stringWithFormat function. This is what I am doing. NSString *category = [row objectForKey:@"category"]; NSString *logonUser = [row objectForKey:@"username"]; user.text = [NSString stringWithFormat:@"In %@ by %@", category, logonUser]; The problem here is that it always print only one variable. Say if there is "Sports" in category and "Leo" in logonUser it will print "In Sports" and skip the remaining text. It should print "In Sports by Leo". Thanks

  • NSFetchedResultsController: using of NSManagedObjectContext during update brings to crash

    - by Kentzo
    Here is the interface of my controller class: @interface ProjectListViewController : UITableViewController <NSFetchedResultsControllerDelegate> { NSFetchedResultsController *fetchedResultsController; NSManagedObjectContext *managedObjectContext; } @end I use following code to init fetchedResultsController: if (fetchedResultsController != nil) { return fetchedResultsController; } // Create and configure a fetch request with the Project entity. NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Project" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; // Create the sort descriptors array. NSSortDescriptor *projectIdDescriptor = [[NSSortDescriptor alloc] initWithKey:@"projectId" ascending:YES]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:projectIdDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; // Create and initialize the fetch results controller. NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:nil]; self.fetchedResultsController = aFetchedResultsController; fetchedResultsController.delegate = self; As you can see, I am using the same managedObjectContext as defined in my controller class Here is an adoption of the NSFetchedResultsControllerDelegate protocol: - (void)controllerWillChangeContent:(NSFetchedResultsController *)controller { // The fetch controller is about to start sending change notifications, so prepare the table view for updates. [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath { UITableView *tableView = self.tableView; switch(type) { case NSFetchedResultsChangeInsert: [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeUpdate: [self _configureCell:(TDBadgedCell *)[tableView cellForRowAtIndexPath:indexPath] atIndexPath:indexPath]; break; case NSFetchedResultsChangeMove: if (newIndexPath != nil) { [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation:UITableViewRowAnimationFade]; } else { [tableView reloadSections:[NSIndexSet indexSetWithIndex:indexPath.section] withRowAnimation:UITableViewRowAnimationFade]; } break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type { switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:sectionIndex] withRowAnimation:UITableViewRowAnimationFade]; break; } } - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { [self.tableView endUpdates]; } Inside of the _configureCell:atIndexPath: method I have following code: NSFetchRequest *issuesNumberRequest = [NSFetchRequest new]; NSEntityDescription *issueEntity = [NSEntityDescription entityForName:@"Issue" inManagedObjectContext:managedObjectContext]; [issuesNumberRequest setEntity:issueEntity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"projectId == %@", project.projectId]; [issuesNumberRequest setPredicate:predicate]; NSUInteger issuesNumber = [managedObjectContext countForFetchRequest:issuesNumberRequest error:nil]; [issuesNumberRequest release]; I am using the managedObjectContext again. But when I am trying to insert new Project, app crashes with following exception: Assertion failure in -[UITableView _endCellAnimationsWithContext:], /SourceCache/UIKit_Sim/UIKit-984.38/UITableView.m:774 Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (4) must be equal to the number of rows contained in that section before the update (4), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted).' Fortunately, I've found a workaround: if I create and use separate NSManagedObjectContext inside of the _configureCell:atIndexPath: method app won't crash! I only want to know, is this behavior correct or not?

  • Best architecture for a social media app

    - by Sky
    Hey guys, Im working on promising project that develops a new social media app for web and mobile. We are at begin defining functionalities. Nevertheless, I'm thinking ahead on architecture. So I'm asking: 1 - Whats the best plataform to develop the core of this aplication that will have a Rest API interface. 2 - Whats the best database that will scale and grow with my application. As far as I researched, these were the answers I found most interesting: For database: Cassandra NoSQL DB, amazing scalabilty, amazing write performance, good read performance (will be improved on 0.6). I think i will choose that one. Zookeer for transactions on Cassandra. I think that 2 technologies rly good for that propose. What do you think guys? On the front end that will serve the REST API, i dont have a final candidate. For this one i have questions based on Perfomance X Scalabilty X Fast Development/Maintenance. Java or .Net As far as I researched, brings the best balance of this requisits. Python, pearl and Rail, has the best (Fast Development/Maintenance), but sux on all other. C or C++ I dont even consider, because its (Fast Development/Maintenance) sux... So what do you guy think about it?

  • UITableViewCells of different heights place their accessoryViews at different X positions

    - by Jasarien
    Hey Guys, My app has some table cells that vary in height. The cells can also have a UIButton set to be a detail disclosure button (round, blue with arrow) as their accessory view. Depending on the height of the cell, the accessory view is positioned differently. At first I thought it was my layout code for my cell that was causing the problem, so I set up a quick independent test that uses vanilla UITableCells to remove the possibility that it could be my fault. I set up a view in interface builder, and just added a view table cells to the view, set their heights to different values and then added a detail disclosure button to each. Nothing more, nothing less. This is what I see: I added the size guides (thanks to Xscope) so you can see the difference in the accessory view x positions. The heights are: top 37px mid 68px bottom 44px (default, untouched height) If I increase the height any heigher than 68px the accessory view doesn't move any further to the left. Is this a bug? Is there any way I can prevent this from happening?

  • Using a UIPickerView to make a CoreData Relationship

    - by DVG
    Okay, so I have a fairly simple application set up. I have two different CoreData Entities, Games and Platforms, each have one attribute: name, and they have a one-to-many relationship between them. Platforms are populated on the first launch of the application, and will never change as a result of user input. I'm working on my Add view to let the user add new games to their personal database, and each game should select from a platform. The add view itself is a grouped table view with static custom cells. Tapping the platform cell should advance the user to another view to select the platform. My thought is that UIPickerView seems like a logical choice for the control, since the Platform list is static, but I'm not sure how to use it with CoreData. Even if I construct a fetch request to get the Platform objects and extract the strings out, how do I go about linking the new Game object to the original Platform object?

  • Google Visualization API - Line and Scatter on one Chart.

    - by ealgestorm
    Does any one know if it is possible to use the Default Google Scatter Chart in the Google Visualizations Gallery to draw a scatter chart that has both a series with points only, a series with a line of best fit and on top of this a set of lines across the chart indicating limits. i.e. at +/- 20% etc. The chart we need is actually a Control Chart with multiple series and individual formatting of each series displayed on the chart. i.e some series with only points other series with a line of best fit. Does any one know of a Control Chart that has already been done using the Google Visualization API?

    I have a regular text field on a view and I'd like to make use of the search button on the iPhones keyboard. For the life of me, I can't figure out how to do this. There doesn't seem to be any event exposed that I can wire up that specifically relates to the search button on the keyboard. I've googled around, but I also haven't found anything related to this subject.

  • How to implement checkout/basket system

    - by ct2k7
    Hi, I'm making an app for fun and would like to know how to implement a checkout/basket system on the app. Basically, a list of products is pulled in from a web server in form of XML file, which is then displayed in a UITableView controller. A tap on the cell takes the user to a more detailed overview of the product. The app would need to be able to get the product into a basket type thing, and this is where I'm getting stuck. Are there any code samples that I could take a look at?
