  • How to set the width of a cell in a UITableView in grouped style

    - by Tomen
    I have been working on this for about 2 days, so i thought i share my learnings with you. The question is: Is it possible to make the width of a cell in a grouped UITableView smaller? The answer is: No. But there are two ways you can get around this problem. Solution #1: A thinner table It is possible to change the frame of the tableView, so that the table will be smaller. This will result in UITableView rendering the cell inside with the reduced width. A solution for this can look like this: -(void)viewWillAppear:(BOOL)animated { CGFloat tableBorderLeft = 20; CGFloat tableBorderRight = 20; CGRect tableRect = self.view.frame; tableRect.origin.x += tableBorderLeft; // make the table begin a few pixels right from its origin tableRect.size.width -= tableBorderLeft + tableBorderRight // reduce the width of the table tableView.frame = tableRect; } Solution #2: Having cells rendered by images This solution is described here: http://cocoawithlove.com/2009/04/easy-custom-uitableview-drawing.html I hope this information is helpful to you. It took me about 2 days to try a lot of possibilities. This is what was left.

  • Display TableViews corresponding to segmentedControl in a single tableview without pushing a new view

    - by user1727927
    I have a tableViewController where I have used the Interface Builder to insert a Segmented Controller having two segments. Since by default, first segment is always selected, I am not facing any problem in displaying the tableview corresponding to first segment. However, when I click on the second segment, I want to display another tableView. Here goes the problem. I am calling newTableViewController class on clicking the second segment. Hence, this view is getting pushed instead. Please suggest me a method to have these two tableViews in the main tableView upon clicking the segments. I have used switch case for switching between the segments. Here's the relevant part of the code: This method is in the FirstTableViewController since first segment is by default selected. -(IBAction) segmentedControlChanged { switch(segmentedControl.selectedSegmnentIndex) { case 0: //default first index selected. [tableView setHidden:NO]; break; case 1: NewViewController *controller=[[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil]; self.navigationController pushViewController:controller animated:YES]; [controller release]; break; default: break; } }

  • EventKitUI view and edit problem!

    - by Alish
    I try to to find a solution to do View and Edit of a the item from a tablview. My application base on UITabBarController. Each of the Bar items contain a class with a a couple of UIViews. This is the first items of UITabBarController. I done Add event from Apple sample code: SimpleEKDemo. Add Event working without any problem. I tried to add View and Edit part to the code. I would able to select an items from tableView to edit the selected item. But after I tried to add code from SimpleEKDemo to my code, I realized I have to add UINavigationController to the implement. So I did. After I add that it's came to the items of UITabBarController. Also I even the Add Event didn't worked very well (I couldn't insert event name and location. but edit was working. So I need to know: 1- Is it possible to implement Edit/View without using UINavigationController. If yes please let me know a sample code. 2- If I must use UINavigationController. Because I don't need UINavigationController to become it the first page and I don't need any bar added to my application. Is it possible it's appear in the application when I choose a item of tableView but appear alike that! Snapshots: https://public.me.com/alish (pict.zip)

  • How to set UITableViewCell highlighted image

    - by SmartTree
    I want to launch a method every time when user just highlights a cell (doesn't select it) in UITableView. Could you tell me please, how is it possible to do this ? I want to do it because I have a custom cell with a pictures on it and I want to change pictures every time when user highlights the cell. UPD: By highlight I mean that user just highlights a cell and don't release the finger from it. By select I mean when didSelectRowAtIndexPath is being launched (so the user releases the finger from the cell after he presses on it)

  • 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.

  • Objective C convention: When to use For and when to use With

    - by Howard
    According to the Apple guideline , seems it is confusing, e.g. for method viewWithTag In Java, I would have a method called getViewByTag // Java version, equivalent to viewWithTag in Obj-C But I also found there are some method like objectForKey, so why not just use objectWithKey instead? getObjectByKey or just get // Java version, equivalent to objectForKey, // but why not objectWithKey? Or not viewForKey above?

  • UITextView refuses to change its color

    - by Friendlydeveloper
    Hello, in some cases things you'd expect to solve within a sec turn out to become a lifetime adventure. This is one of these cases :) All I wanted to do, is simply change the text color of one of my UITextViews. So far I tried: UIColor *myColor = [UIColor colorWithHue:38 saturation:98 brightness:100 alpha:1.0]; [myTextView setTextColor:myColor]; OR UIColor *myColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"colorImage.png"]]; [myTextView setTextColor:myColor]; Both seem to work fine for UILabels, but fail for UITextView elements. When I try [UIColor colorWithHue... I only get a reddish kinda color, no matter what values I choose (except values for black and white. They work). The colorWithPatternImage does not change textColor at all. Strange isn't it? I obviously must be missing something. Help is very much appreciated. Thanks in advance.

  • How many android apps are open source?

    - by Alex
    I know that the android plattform is open source. What I am interested in is the share of open source Android apps, thus developers that realease their own apps under a open source license. Does anybody have an idea, how to get this information?

  • 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!

  • 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!

  • best way to use CoreLocation across multiple views

    - by Matt
    I have two views in my app, one is a general view where CoreLocation works away calculating the users location while the user is doing other stuff in the view. The second view is accessed by the user when they touch a button allowing them to locate themselves more accurately using a mapview and MapKit, i would like the mapview in this view to show the location that CoreLocation has already identified in the first view AND to continue displaying this location based on updates from CoreLocation in the other view. Is the best way here to create a singleton that encapsulates the CoreLocation stuff and have this referenced in the view with the map, or to use notifications ? or to use some other better practice for my scenario ? Thanks

  • SQLite3 - select date range not working

    - by iFloh
    yet anotherone that gives me grief. In a SQLite3 DB Select I query for a date range specified in (NSDate *)fromDate to (NSDate *)toDate const char *sql = "SELECT * FROM A, B WHERE A.key = B.key AND A.date between ? and ?"; After opening the DB I run the query in Objective-C as follows: NSDateFormatter *tmpDatFmt = [[[NSDateFormatter alloc] init] autorelease]; [tmpDatFmt setDateFormat:@"dd-MM-yyyy"]; sqlite3_stmt *stmt; if(sqlite3_prepare_v2(db, sql, -1, &stmt, NULL) == SQLITE_OK) { NSLog(@"From %s to %s;", [[tmpDatFmt stringFromDate:fromDate] UTF8String], [[tmpDatFmt stringFromDate:toDate] UTF8String]); sqlite3_bind_text(stmt, 1, [[tmpDatFmt stringFromDate:fromDate] UTF8String], -1, SQLITE_STATIC); // first '?' sqlite3_bind_text(stmt, 2, [[tmpDatFmt stringFromDate:toDate] UTF8String], -1, SQLITE_STATIC); // second '?' while(sqlite3_step(stmt) == SQLITE_ROW) { NSLog(@"Success");} In the database I have several records that match the date range: 12-04-2010 = in seconds 1271059200 13-04-2010 = in seconds 1271145600 13-04-2010 = in seconds 1271152800 14-04-2010 = in seconds 1271267100 When I run it the first NSLog shows From 2010-04-01 to 2010-04-30 my problem is the records are not selected (no "Success" shows in the log) and I don't understand why. earlier I had miscalculated the dates 2 days later as 14-04-2010 = in seconds 1271232000 15-04-2010 = in seconds 1271318400 15-04-2010 = in seconds 1271325600 16-04-2010 = in seconds 1271439936 These dates worked fine (4 x "Success in the log). I am puzzled ...

  • titleForHeaderInSection is not updating Section Header information correctly

    - by Jim
    I have two tableviews where one navigates to the next. Both use more or less the same code and use the managedObjectContext and FetchedResultsController design pattern to provide the relevant data for both tables. My problem happens when I navigate from the first to the second tableview and the data has only one Section Header / Row in the tableview. The data will then not update Section Header information. It does when there is more than one row but not if there is only one row. It leaves the information from the first attempt in place. I can confirm the row data is correct so the relevant data should be being passed to the Section Header correctly but it isn't. Has anyone else come across this problem?

  • What is the best way to properly test object equality against an array of objects?

    - by radesix
    My objective is to abort the NSXMLParser when I parse an item that already exists in cache. The basic flow of the program works like this: 1) Program starts and downloads an XML feed. Each item in the feed is represented by a custom object (FeedItem). Each FeedItem gets added to an array. 2) When the parsing is complete the contents of the array (all FeedItem objects) are archived to the disk. The next time the program is executed or the feed is refreshed by the user I begin parsing again; however, since a cache (array) now exists as each item is parsed I want to see if the object exists in the cache. If it does then I know I have downloaded all the new items and no longer need to continue parsing. What I am learning, I think, is that I can't use indexOfObject or indexOfObjectIDenticalTo: because these really seem to be checking to see that the objects are using the same memory address (thus identical). What I want to do is see if the contents of the object are equal (or at least some of the contents). I've done some research and found that I can override the IsEqual method; however, I really don't want to iterate/enumerate through the entire cache contents table for every newly parsed XML FeedItem. Is iterating through the collection and testing each one for equality the only way to do this or is there a better technique I am not aware of? Currently I am using the following code though I know it needs to change: NSUInteger index = [self.feedListCache.feedList indexOfObject:self.currentFeedItem]; if (index == NSNotFound) { }

  • how to create a custom settings view / make cell label editable

    - by Lex
    Hi everyone, I need to create a custom settings view used within the app. The app is a mockup so it actually does have one already, it uses a UITableViewCellStyleValue1, but nothing is editable. So essentially what I would like to have is the same thing but with editable detailTextLabel (the label on the right hand side), what's the best way to do this?
