  • NSFetchedResultsController - Delegate methods crashing under iPhone OS 3.0, but NOT UNDER 3.1

    - by Scott Langendyk
    Hey guys, so I've got my NSFetchedResultsController working fine under the 3.1 SDK, however I start getting some weird errors, specifically in the delegate methods when I try it under 3.0. I've determined that this is related to the NSFetchedResultsControllerDelegate methods. This is what I have set up. The inEditingMode stuff has to do with the way I've implemented adding another static section to the table. - (void)controllerWillChangeContent:(NSFetchedResultsController*)controller { [self.tableView beginUpdates]; } - (void)controller:(NSFetchedResultsController *)controller didChangeSection:(id <NSFetchedResultsSectionInfo>)sectionInfo atIndex:(NSUInteger)sectionIndex forChangeType:(NSFetchedResultsChangeType)type{ NSIndexSet *sectionSet = [NSIndexSet indexSetWithIndex:sectionIndex]; if(self.inEditingMode){ sectionSet = [NSIndexSet indexSetWithIndex:sectionIndex + 1]; } switch (type) { case NSFetchedResultsChangeInsert: [self.tableView insertSections:sectionSet withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteSections:sectionSet withRowAnimation:UITableViewRowAnimationFade]; break; default: [self.tableView reloadData]; break; } } - (void)controller:(NSFetchedResultsController *)controller didChangeObject:(id)anObject atIndexPath:(NSIndexPath *)indexPath forChangeType:(NSFetchedResultsChangeType)type newIndexPath:(NSIndexPath *)newIndexPath{ NSIndexPath *relativeIndexPath = indexPath; NSIndexPath *relativeNewIndexPath = newIndexPath; if(self.inEditingMode){ relativeIndexPath = [NSIndexPath indexPathForRow:indexPath.row inSection:indexPath.section + 1]; relativeNewIndexPath = [NSIndexPath indexPathForRow:newIndexPath.row inSection:newIndexPath.section + 1]; } switch(type) { case NSFetchedResultsChangeInsert: [self.tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:relativeNewIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; case NSFetchedResultsChangeDelete: [self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:relativeIndexPath] withRowAnimation:UITableViewRowAnimationFade]; break; default: [self.tableView reloadData]; break; } } -(void)controllerDidChangeContent:(NSFetchedResultsController *)controller{ [self.tableView endUpdates]; } When I add an entity to the managed object context, I get the following error: Serious application error. Exception was caught during Core Data change processing: *** -[NSCFArray objectAtIndex:]: index (1) beyond bounds (1) with userInfo (null) I put a breakpoint on objc_exception_throw, and the crash seems to be occuring inside of controllerDidChangeContent. If I comment out all of the self.tableView methods, and put a single [self.tableView reloadData] inside of controllerDidChangeContent, everything works as expected. Anybody have any idea as to why this is happening?

  • How can I use this animation code?

    - by O.C.
    I'm a newbie and I need some help. I want to display a popup image over a given UIView, but I would like it to behave like the UIAlertView or like the Facebook Connect for iPhone modal popup window, in that it has a bouncy, rubbber-band-like animation to it. I found some code on the net from someone who was trying to do something similar. He/she put this together, but there was no demo or instructions. Being that I am so new, I don't have any idea as to how to incorporate this into my code. This is the routine where I need the bouncy image to appear: - (void) showProductDetail { . . . //////////////////////////////////////////////////////////////////////// // THIS IS A STRAIGHT SCALE ANIMATION RIGHT NOW. I WANT TO REPLACE THIS // WITH A BOUNCY RUBBER-BAND ANIMATION _productDetail.transform = CGAffineTransformMakeScale(0.1,0.1); [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; _productDetail.transform = CGAffineTransformMakeScale(1,1); [UIView commitAnimations]; } . . . } This is the code I found: float pulsesteps[3] = { 0.2, 1/15., 1/7.5 }; - (void) pulse { self.transform = CGAffineTransformMakeScale(0.6, 0.6); [UIView beginAnimations:nil context:nil]; [UIView setAnimationDuration:pulsesteps[0]]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(pulseGrowAnimationDidStop:finished:context:)]; self.transform = CGAffineTransformMakeScale(1.1, 1.1); [UIView commitAnimations]; } - (void)pulseGrowAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:pulsesteps[1]]; [UIView setAnimationDelegate:self]; [UIView setAnimationDidStopSelector:@selector(pulseShrinkAnimationDidStop:finished:context:)]; self.transform = CGAffineTransformMakeScale(0.9, 0.9); [UIView commitAnimations]; } - (void)pulseShrinkAnimationDidStop:(NSString *)animationID finished:(NSNumber *)finished context:(void *)context { [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:pulsesteps[2]]; self.transform = CGAffineTransformIdentity; [UIView commitAnimations]; } Thanks in advance for any help that you can give me.

  • iPhone cocos2d CCTMXTiledMap tile transitions

    - by Jeff Johnson
    I am using cocos2d on the iPhone and am wondering if it is possible to use a texture mask in order to create tile transitions / fringe layer. For example, a grass tile and a dirt tile, I would want a tile that had both grass and dirt in it... Has anyone done this, or is the only way to create one tile for every possible transition?

  • Display large PDF using iPhone SDK

    - by MadJawa
    Hello, I was wondering what is the best way to display a big PDF file (it's a map actually) using iPhone SDK (the file is around 5MB), because it's really slow in a UIWebView. I want to be able to scroll through the PDF and zoom in/out. Also do you think that it would be better to convert it to a PNG? Thank in advance
