  • How to select "child" entities in subview?

    - by Andy
    I am trying to manage a drill-down list of data. I've got an entity, Contact, that has a to-many relationship with another entity, Rule. In my root view controller, I use a fetched results controller to manage and display the list of Contacts. When a Contact is tapped, I push a new view controller onto the stack with a list of the Contact's Rules. I have not been able to figure out how to use a second fetched results controller to display the Rules, so I'm using the following: // create a set of the contact's rules rules = [NSMutableSet set]; rules = [self.contact mutableSetValueForKey:@"rule"]; // create an array of rules from the set arrayOfRules = [NSMutableArray arrayWithCapacity:[rules count]]; for (id oneObject in rules) [arrayOfRules addObject:oneObject]; // sort the array of rules NSSortDescriptor *descriptor = [[NSSortDescriptor alloc] initWithKey:@"phoneLabel" ascending:YES]; [arrayOfRules sortUsingDescriptors:[NSArray arrayWithObject:descriptor]]; [descriptor release]; I create a set of Rules, then use that to create an array of Rules for sorting. I then use these two collections to populate the grouped table view. All of this appears to be working correctly. Here's my problem: There are several different actions a user can take in this view, and most of them require that I know which Rule was tapped. But I can't figure out how to get that. For instance, say a user wants to delete a Rule. It seems to me the proper approach is something like... [rules removeObject:ruleObjectToBeRemoved] ...but I can't figure out how to specifiy ruleObjectToBeRemoved. I hope all of this makes sense. As usual, thanks in advance for any advice you can offer.

  • About setStatusBarHidden

    - by iTarek
    Today my app approved, but I got emails from users says it crash. I figured out that [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide]; Is the problem, Because users have firmware 3.1.x this API is not working and app crash. So I have replace it with if ([[[UIDevice currentDevice] systemVersion] floatValue]>=3.2) [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation: UIStatusBarAnimationSlide]; else [[UIApplication sharedApplication] setStatusBarHidden:YES animated:YES]; My questions... Is what I did the best solution? Why XCODE did not warn me that SetStatusBarHidden withAnimation is not in 3.0 while I set my Traget OS firmware 3.0? Do I have to check on every API to see if it is working with my Target OS? Thank you

  • Best way to create Default.png image for iPhone app

    - by Alex
    Originally I though I'll just take a screenshot of my app on the iPhone then tweak it in Photoshop. The images should be 480 x 320 according to Apple doc, and the dimensions of my screenshot are 480 x 320. But, the screenshot contains notification area (where reception bars, battery life, etc. are displayed) So, if I chop that part off my image will be a bit shorter and not 480px high. What do I do? Submit a shorter image? Stretch it up so it's 480px but without the notification bar? Submit it with the notification bar in the image? How did you create your Default.png?

  • memory management: am i doing something wrong here?

    - by z s
    Hi, In a very small number of cases in my iphone app, I get a crash after the for loop in the code below: ABAddressBookRef addressBookInit = ABAddressBookCreate(); CFMutableArrayRef abContacts = (CFMutableArrayRef)ABAddressBookCopyArrayOfAllPeople(addressBookInit); // get array of all contacts CFArraySortValues (abContacts, CFRangeMake(0, CFArrayGetCount(abContacts)), (CFComparatorFunction)ABPersonComparePeopleByName, (void *)ABPersonGetSortOrdering()); NSArray *copypeople = (NSArray *) abContacts; NSMutableArray *tempTheadlist = [[NSMutableArray alloc] init]; for (int i=0; i < copypeople.count; i++) { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; ABRecordRef record = [copypeople objectAtIndex:i]; if (blah blah) [tempThreadList addObject: someObject]; [pool release]; } // POINT OF CRASH AFTER LOOP ENDS if (tempTheadlist.count > 0) [NSThread detachNewThreadSelector: @selector(loading_pictures:) toTarget:self withObject:tempTheadlist]; [tempTheadlist release]; [copypeople release]; CFRelease(addressBookInit); Any reason why it should crash at any point here?

  • Why Camera.setParameters(Camera.Parameters) does not work on Sony-Ericsson X10 and Droid?

    - by mobilekid
    Has anyone come across a strange behaviour with the Camera API when used on Sony-Ericsson X10 or Droid? For example the following code doesn't work on those devices. As a result I'm getting a lot of negative feedback on the Market translating into many cancelled orders... mParameters.set("rotation", orientation); mParameters.set("jpeg-quality", img_quality); mParameters.set("picture-size", "1024x768"); mCamera.setParameters(mParameters); Could you suggest an alternative way of achieving the same? Thanks.

  • CADisplayLink stops updating when UIScrollView scrolled

    - by Tricky
    Title is quite self explanatory, but I have some animation being done in a loop triggered by CADisplayLink. However, as soon as I scroll a UIScrollView I have added to my view hierarchy, the animation stops immediately, only to return again when scrolling has completely stopped and come to a standstill.... Anyway to cancel this behaviour?

  • Cannot change UIImageView frame in a custom table cell.

    - by jkally
    I have a custom table cell. In it I have put (via the IB) an image view of a certain frame In 'cellForRowAtIndexPath', under certain conditions, I would like to modify the frame of this UIImageView, so I write something like: UIImageView *imgv = (UIImageView *)[cell viewWithTag:1]; CGRect r = CGRectMake(20.0, 20.0, 10.0, 10.0); imgv.frame = r; But nothing expected happens (The frame does move a little though not to where I want, but doesn't change its size at all);

  • plus minus table View cell

    - by user1748387
    I have the following code - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; UIImage * i1 = [UIImage imageNamed: @"inc_01.png"]; UIImage * i2 = [UIImage imageNamed: @"inc_02.png"]; UIImage * i3 = [UIImage imageNamed: @"inc_04.png"]; UIImage * i5 = [UIImage imageNamed: @"inc_05.png"]; UIImage * i6 = [UIImage imageNamed: @"inc_06.png"]; UIImage * i7 = [UIImage imageNamed: @"inchd.png"]; if (cell == nil) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; } if(indexPath.row == 0) { UIImageView * header= [[UIImageView alloc] initWithImage: i1]; cell.backgroundView = header; // Configure the cell… } else if (indexPath.row == 2) { UIImageView *backgroundCellImage=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 280, 11)]; backgroundCellImage.image=[UIImage imageNamed:@"inc_06.png"]; [cell.contentView addSubview:backgroundCellImage]; } else { // Configure the cell… UIImageView *imageView = [[UIImageView alloc] initWithImage: i3]; cell.textLabel.text = @"text"; UIImageView *backgroundCellImage=[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 57, 46)]; backgroundCellImage.image=[UIImage imageNamed:@"inc_02.png"]; UIImageView *backgroundCellImage2=[[UIImageView alloc] initWithFrame:CGRectMake(223, 0, 57, 46)]; backgroundCellImage2.image=[UIImage imageNamed:@"inc_04.png"]; UILabel * label = [[UILabel alloc] initWithFrame:CGRectMake(57, 0, 166, 46)]; label.text = @"wow"; [cell.contentView addSubview:backgroundCellImage]; [cell.contentView addSubview:backgroundCellImage2]; [cell.contentView addSubview:label]; } return cell; } that basically creates a table view and puts an image to the left and right of each cell. I want it so that people can click on the left or right image in each cell, and something different happens based on the cell number. So if they click on the left image for cell in row 1, a function gets call with the row number they clicked on, and an indicator telling me they clicked on the left image and not the right image. How can I do that using objective-c?
