  • Core Data: Mass updates possible?

    - by wgpubs
    Is it possible to do mass updates on a given entity in Core Data? Given an Person entity for example, can I do something like this: Person.update(@"set displayOrder = displayOrder + 1 where displayOrder > 5") Or is my only option to fetch all the entities needed and then loop through and update them individually??? Thanks

  • Should I really use a UITableView in this situation?

    - by mystify
    Imagine you have a view like this: At the top, there is an UISegmentedControl with two segments. It functions like a tab. Pressing one segment will activate this particular content below that UISegmentedControl. Below the UISegmentedControl are some switches. These modify the way how the content should be rendered. And finally, below those switches, there's a table. Imagine a table not in sense of UITableView, but just what it really is: A table. It shows little messages like twitter messages or chat messages for example, one below the other. Like you know it from skype and other chats. Basically they're just rows with some formatting. A label, some image views, some lines, a background. Pretty basic. The data comes from an array. No core data. The whole thing including the segmented control and setup switches must be scrollable. So what I did is: I put all this stuff in an UIScrollView. Now I have to make the decision if I would use a UITableView inside there for that table part, or if I would just print a lot of rows on to the scroll view (with -drawRect:). But some problems stick in my head: Can I put a UITableView inside a UIScrollView? I assume this makes a lot of problems. I don't want that the table part is separately scrollable. Again imagine that view: First there are some basic choice things (segmented control, switches). Then there comes the table. When you scroll, the whole thing scrolls. That's mainly because this first part with the settings can be pretty big, so you would want to scroll it away. The next thing is: Can I customize UITableView in such a way, that it consists of two parts? One for that settings part, and one for the actual data to display?

  • Detect when home button is pressed iOS

    - by nick
    I have several iOS apps that all use the same port to listen for a network beacon. On the main view I use viewWillDisappear to close the port when another view is opened, which was working great. Then I noticed if I pressed the home button from the main view controller without opening another view to close the port, then the port stays open and non of my other apps can listen on that port any more. I then tried using viewWillUnload, but that doesn't seem to get called when I press the home button. -(void)viewWillUnload { //[super viewWillUnload]; NSLog(@"View will unload"); [udpSocket close]; udpSocket = nil; } View will unload is never displayed in the console, which leads me to believe that the method is never getting called. Is there a way to detect when the home button is pressed so I can close my port?

  • iPad search bar bad memory access?

    - by Geoff Baum
    Hello all, So I am trying to implement a search bar in my app and am very close but can't seem to figure out where this memory error is occurring. This is what part of my search method looks like: filters = [[NSMutableArray alloc] init]; NSString *searchText = detailSearch.text; NSMutableArray *searchArray = [[NSMutableArray alloc] init]; // Normally holds the object (ex: 70 locations) searchArray = self.copyOfFilters ; //This is the line that is breaking after ~2-3 letters are entered in the search for (NSString *sTemp in searchArray) { NSRange titleResultsRange = [sTemp rangeOfString:searchText options:NSCaseInsensitiveSearch]; if (titleResultsRange.length > 0) [filters addObject:sTemp]; } displayedFilters = filters; copyOfFilters is a deep copy of the displayed filters that appear when the view first loads via: self.copyOfFilters = [[NSMutableArray alloc] initWithArray:displayedFilters copyItems:YES]; I have traced through the entry of letters and it is accurate after 2 letters, but once you try and enter a letter after a space in the search bar, it crashes. The value of copyOfFilters = {(int)[$VAR count]} objects. Does anyone know what may be causing this? Thanks!

  • Uitableview not able to hold data

    - by pankaj
    Hi i have a uitableview, i am displaying some data of about 200 rows in it. Data will be displayed in several sections which will be determined at run time. I am able to get sections but i am not able to display data for a particular section in correct order. I have data in the form of dictionaries in an array. My Code: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { TeraGoAppDelegate *appDel = (TeraGoAppDelegate *)[[UIApplication sharedApplication] delegate]; UITableViewCell *cell = nil; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease]; cell.textLabel.text = [(NSMutableDictionary *)[appDel.arrEqp objectAtIndex:countEqpIndex] objectForKey:@"EQP_NAME"]; cell.textLabel.font = [UIFont fontWithName:@"Arial" size:14]; if(![[(NSMutableDictionary *)[appDel.arrEqp objectAtIndex:indexPath.row] objectForKey:@"select"] isEqualToString:@"0"]) { cell.accessoryType = UITableViewCellAccessoryCheckmark; } else cell.accessoryType = UITableViewCellAccessoryNone; } // Set up the cell... return cell; } I am trying to use indexPath.row but its values initialises from 0 in every section I can not get data from array in this case as i dont have index of array to get data. How will i get the index of array whose values i need to display????

  • Redrawing content of UIWebView

    - by btate
    I have a bunch of webviews with static html content that I'm putting in a scroll view as pages. That works fine, but having 20 something full screen subviews of the scroll view is causing some lag. I solved that by only placing 5 at a time in there. The current view, and the two next and two previous. The problem now is that any web view that is not a subview of the scroll view is not drawing correctly based on the device orientation. The frame of the webview is printing out correct, but the actual content is drawing in portrait mode. So there is essentially a strip of blank space to the right of the content. How do I go about re rendering the content without reloading the page? Here's the relevant code: - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation) fromInterfaceOrientation{ [self resizeSubViews]; } - (void) setupWebViews{ if(_webViews == nil) _webViews = [[NSMutableArray alloc] init]; // This is where the navigation would come into play as far as loading up available web views [_webViews removeAllObjects]; // for loop here to create web views for (int i = 0; i < 20; i++) { //CDCWebViewController *webView = [[[MyInternalWebView alloc] initWithFrame:_webViewWrapper.frame] retain]; MyInternalWebView *page = [[[MyInternalWebView alloc] init] retain]; [page loadRequest:[NSURLRequest requestWithURL:_url]]; [page setCdcIWVdelegate:self]; [page setTestIndex:i]; [page setPageIndex:i]; [_webViews addObject:page]; [self loadScrollViewWithPage:i]; } [self clearUnusedWebViews:_pageControl.currentPage]; } - (void) setupWebViewWrapper{ // a page is the width of the scroll view _webViewWrapper.pagingEnabled = YES; _pageControl = [[[UIPageControl alloc] init] retain]; _webViewWrapper.showsHorizontalScrollIndicator = NO; _webViewWrapper.showsVerticalScrollIndicator = NO; _webViewWrapper.scrollsToTop = NO; _webViewWrapper.delegate = self; _pageControl.numberOfPages = [_webViews count]; _pageControl.currentPage = 0; } - (void) resizeSubViews{ // The frame is set in IB _webViewWrapper.contentSize = CGSizeMake(_webViewWrapper.frame.size.width * [_webViews count], _webViewWrapper.frame.size.height); // Move the content offset. _webViewWrapper.contentOffset = CGPointMake(_webViewWrapper.frame.size.width * _pageControl.currentPage, _webViewWrapper.contentOffset.y); for (MyInternalWebView *subview in _webViewWrapper.subviews) { // Reset the frame height and width here? CGRect frame = _webViewWrapper.frame; frame.origin.x = frame.size.width * subview.pageIndex; frame.origin.y = 0; [subview setFrame:frame]; } } //***************************************************** //* //* ScrollView Functions //* //***************************************************** - (void)loadScrollViewWithPage:(int)page { // Make sure we're not out of bounds if (page < 0) return; if (page >= [_webViews count]) return; MyInternalWebView *webView = [_webViews objectAtIndex:page]; // Add the preloaded webview to the scrollview if it's not there already if (nil == [webView superview]) { CGRect frame = _webViewWrapper.frame; //NSLog(@"width = %f", frame.size.width); frame.origin.x = frame.size.width * page; frame.origin.y = 0; //NSLog(@"setting frame for page %d %@", page, NSStringFromCGRect(frame)); [webView setFrame:frame]; [_webViewWrapper addSubview:[_webViews objectAtIndex:page]]; // Now that the new one is loaded, clear what doesn't need to be here [self clearUnusedWebViews:page]; } } - (void) clearUnusedWebViews: (NSInteger) page{ for (int i = 0; i < [_webViews count]; i++) { if ((page - i) <= 2 && i - page <= 2) { continue; } [[_webViews objectAtIndex:i] removeFromSuperview]; } } - (void)scrollViewDidScroll:(UIScrollView *)sender { // Switch the indicator when more than 50% of the previous/next page is visible CGFloat pageWidth = _webViewWrapper.frame.size.width; NSInteger page = floor((_webViewWrapper.contentOffset.x - pageWidth / 2) / pageWidth) + 1; _pageControl.currentPage = page; // load the visible page and the page on either side of it (to avoid flashes when the user starts scrolling) [self loadScrollViewWithPage:page - 2]; [self loadScrollViewWithPage:page - 1]; [self loadScrollViewWithPage:page]; [self loadScrollViewWithPage:page + 1]; [self loadScrollViewWithPage:page + 2]; }

  • How to notify ViewController on parse end with multiple ViewControllers using a single parser.

    - by objneodude
    Hello, I have created a RSS parser and 3 TableViews and it parses the RSS files fine but I don't know how to notify the TableViewController when parsing has ended so it can update the view. The TableViewController initiates the parser and the parsing of a feed. parser = [[RSSParser alloc] initWithURL:@"http://randomfeed.com"]; I can access the single feed items like [parser feedItems]; In parser.m i have implemented the delegate methods of NSXMLParser: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName - (void)parserDidEndDocument:(NSXMLParser *)parser So how do i get parserDidEndDocument to notify my controllers so i can add the data to the tableview. Cheers from a obj-c beginner.

  • How to navigate to a UITableView position by the cell it's title using indexing

    - by BarryK88
    I'm using a UITableView filled with a around 200 cells containing a title, subtitle and thumbnail image. I want to a have a selection method just like within the contact App from Apple where you can select a character from the alphabet. I'm at the point where I've drawn the selection interface (A,B,C etc), and via it's delegate I'm retrieving the respective index and title (i.e: A = 1, B = 2, C = 3 etc.). Now I want to navigate to the first cell, where the first character of the cell it's title is starting with the selected index character. Just like the contacts App. Can someone give me a direction for how to implement such functionality. - (NSInteger)tableView:(UITableView *)tableView sectionForSectionIndexTitle:(NSString *)title atIndex:(NSInteger)index I filled my sectionIndex by means of - (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tableView { if(searching) return nil; NSMutableArray *tempArray = [[NSMutableArray alloc] init]; [tempArray addObject:@"A"]; [tempArray addObject:@"B"]; [tempArray addObject:@"C"]; [tempArray addObject:@"D"]; [tempArray addObject:@"E"]; [tempArray addObject:@"F"]; [tempArray addObject:@"G"]; [tempArray addObject:@"H"]; [tempArray addObject:@"I"]; [tempArray addObject:@"J"]; [tempArray addObject:@"K"]; [tempArray addObject:@"L"]; [tempArray addObject:@"M"]; [tempArray addObject:@"N"]; [tempArray addObject:@"O"]; [tempArray addObject:@"P"]; [tempArray addObject:@"Q"]; [tempArray addObject:@"R"]; [tempArray addObject:@"S"]; [tempArray addObject:@"T"]; [tempArray addObject:@"U"]; [tempArray addObject:@"V"]; [tempArray addObject:@"W"]; [tempArray addObject:@"X"]; [tempArray addObject:@"Y"]; [tempArray addObject:@"Z"]; return tempArray; }

  • Load all tab bar views when application first runs

    - by codenoobie
    Here's the problem. I have a tab bar controller with 4 separate views. When I navigate from the first view to the second view, it takes some time to load up the second view. What I want to do is be able to load and initialize all of my tab bar views during my splash screen. That way, when the user navigates between the tab views, there is no wait time. So the question is... how do I manually initialize my individual tab bar views in my app delegate? And once again, thank you stackoverflow!

  • Navigation Bar color doesn't change back? iOS7

    - by TKP
    I have several tableviews with navigation controller. The navigation bar is white for all the views except the last one, which is red. I have [[[self navigationController] navigationBar] setTintColor:[UIColor redColor]; in the viewDidLoad of the last tableview and [[[self navigationController] navigationBar] setTintColor:[UIColor whiteColor]; in the viewDidLoad of other table views. It works fine until I get to the last view and the color of the navigation bar changes to red. When I go back to the previous views, all the previous views' navigation bar has changed to red. Where should I put those codes so the color will remain unchanged? Thanks,

  • Navigation Controller with Tab Bar only on first view

    - by dinoc
    I am seeking advice on how to start my project. I need to use a combination of the navigation controller and tabbar controller but on the second screen, I need the tabbar controller not to be there. Here is a brief description of the two main screens Screen 1 will have a tabbar controller with two tabs. The first tab is a tableview and when you tap on a table cell, it drills down to Screen 2. The second tab is just a filter view that updates the table in the first tab of Screen 1. Screen two is just a details screen from the cells of Screen 1. The catch is that I don't want the TabBar on Screen 2. I am struggling with how to get started. Do I start with a Navigation-based application since I need to be able to drill down? How do I just add a tab bar to the main screen of the navigation based app? I can't start with a Tab Bar application because if I load a navigation controller inside one of the views of the tab controller, then when I drill down inside the nav controller, the tab bar still stays on the next screen when I need it to go away. Any help would be appreciated.
