  • Same object in different nib files?

    - by Michael
    View1 object, which is UIViewController subclass is the same object as File's Owner of View1 nib. So I should manually set the class in both places, one in MainWindow and another in View1 nib files? This sound artificial to me... Either I'm doing something wrong or there has to be better way.

  • Deleted nib still displayed when controller is pushed

    - by yahuie
    I have an application with a UINavcontroller under a tab bar controller. To create the navigation model I want, I push a container UIView object onto the stack to manage additional views(Thanks Frank). When I created the container class, an associated nib file was created along with it. I at first used that nib file, but it turned out it was better not to. So I deleted the nib (and selected 'also move to trash'). The problem is that it still shows up when I push its view controller onto the stack. I have tried emptying the cache in xcode and restarting xcode. What am I missing?

  • UITableView with multiple selections

    - by NewDev
    I have a UITableView with multiple selections enabled. If I select items and scroll the list back and forth they are remembered and shown and selected (blue background). Using the didDeselectRowAtIndexPath and didSelectRowAtIndexPath I am able to keep my own array of selected items. That part works well. However, if I then use the sectionForSectionIndexTitle and jump to a letter, the selection appears to be forgotten - even indexPathForSelectedRows appears to have been reset and is now empty. My own array remembers that an item is selected and I can set the cell.selected in the cellForRowAtIndexPath but the instant I move the list it is forgotten again. Any ideas? Is this a bug, or how do you retain the selection list when jumping to a letter?

  • Text being printed twice in uitableview

    - by user337174
    I have created a uitableview that calculates the distance of a location in the table. I used this code in cell for row at index path. NSString *lat1 = [object valueForKey:@"Lat"]; NSLog(@"Current Spot Latitude:%@",lat1); float lat2 = [lat1 floatValue]; NSLog(@"Current Spot Latitude Float:%g", lat2); NSString *long1 = [object valueForKey:@"Lon"]; NSLog(@"Current Spot Longitude:%@",long1); float long2 = [long1 floatValue]; NSLog(@"Current Spot Longitude Float:%g", long2); //Getting current location from NSDictionary CoreDataTestAppDelegate *appDelegate = (CoreDataTestAppDelegate *) [[UIApplication sharedApplication] delegate]; NSString *locLat = [NSString stringWithFormat:appDelegate.latitude]; float locLat2 = [locLat floatValue]; NSLog(@"Lat: %g",locLat2); NSString *locLong = [NSString stringWithFormat:appDelegate.longitude]; float locLong2 = [locLong floatValue]; NSLog(@"Long: %g",locLong2); //Location of selected spot CLLocation *loc1 = [[CLLocation alloc] initWithLatitude:lat2 longitude:long2]; //Current Location CLLocation *loc2 = [[CLLocation alloc] initWithLatitude:locLat2 longitude:locLong2]; double distance = [loc1 getDistanceFrom: loc2] / 1600; NSMutableString* converted = [NSMutableString stringWithFormat:@"%.1f", distance]; [converted appendString: @" m"]; It works fine apart from a problem i have just discovered where the distance text is duplicated over the top of the detailed text label when you scroll beyond the height of the page. here's a screen shot of what i mean. Any ideas why its doing this?

  • UITableViewCell: Allowing Selective Deletion

    - by Aran Mulholland
    I have a table view and want to allow rearranging of all cells, however there are certain cells that i do not want to be allowed to be deleted. when the UiTableView is put into deletion mode i do not want the red '-' button to appear on the left hand side, and do not want the swipe gesture to bring up the Delete button of these cells but want it to happen for the others. Any ideas?

  • How to calculate end-point at a given center plus an radius and angle?

    - by mystify
    I'm trying to do some basic quartz core drawing with arcs, but have an F in math ;-) I have a point: CGPoint center = CGPointMake(100.0f, 100.0f); CGFloat radius = 50.0f; CGFloat startAngle = 20.0f / 180.0f * M_PI; CGFloat endAngle = 150.0f / 180.0f * M_PI; CGContextAddArc(c, center.x, center.y, radius, startAngle, endAngle, 0); Now I want to draw a little dot on the middle of the arc. I mean, not the center point, but the little curve (arc) which is made up between the angles 20-150 degrees. I looked into quartz but unfortunately, there seems no helper function to calculate this. Probably some hardcore trigonometric logic with atan and stuff of this kind needed?

  • Scroll immediately to row in table before view shows

    - by cannyboy
    A view with a table gets pushed onto the screen and I want it to scroll to a certain row in the table before the screen actually displays. I use this code within the final viewcontroller. NSIndexPath *scrollToPath = [NSIndexPath indexPathForRow:5 inSection:0]; [theTable scrollToRowAtIndexPath:scrollToPath atScrollPosition:UITableViewScrollPositionTop animated:NO]; When I put it in viewDiDAppear method, then it briefly flashes from the intial position of the table (at the top) to the row I want. I don't want it to show the initial position. If I put it in viewDidLoad or viewWillAppear then it crashes with a NSRangeException, presumably because the table isn't set up yet. How would I get it to scroll without showing the initial position?

  • Prevent custom AccessoryView from showing selection when it's UITableViewCell is selected.

    - by groomsy
    To reproduce this, create a UITableView that contains cells with custom AccessoryViews (such as buttons to perform a specific action where touching the other part of the UITableViewCell should perform a different action). If you touch (select) the UITableView, the AccessoryView shows selection (as thought it was touched) as well. I want to prevent this and only show the AccessoryView's selected state when they actually touch the AccessoryView. Thanks in advance, groomsy

  • AccessoryDisclosureIndicator and AccessoryCheckmark on the left side

    - by embedded
    Hi I'm adding support for right-to-left languages for the UITableView. now I need to move the AccessoryDisclosureIndicator and AccessoryCheckmark from the right corner to the left. I'm taking the UIImageView path and Now I'm looking for 2 png icons: one for the AccessoryDisclosureIndicator arrow to the left and the second for the AccessoryCheckmark. Does anyone know where I can get those 2 icons? Is it possible when the user clicks on some cell to switch to the other view to the left and not to the right? Thanks

  • Access problem with NSMutableArray

    - by pbcoder
    Hi, my problem is that I can't access my NSMutableArray in - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {}. I create my NSMutableArray here: nodes = [xmlDoc nodesForXPath:@"/xml/items/item/short_desc" error:nil]; if (nodes != nil && [nodes count] >= 1) { for (int i = 0; i < [nodes count]; i++) { CXMLElement *resultElement = [nodes objectAtIndex:i]; result = [[[[resultElement attributeForName:@"data"] stringValue] copy] autorelease]; [short_desc addObject:result]; } } and I can print out the content of short_desc everywhere with: NSLog([short_desc objectAtIndex:0]); but not in: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ..... NSString *date = [name objectAtIndex:0]; labelDate.text = date; ..... return cell;} if I use: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ..... NSString *date = @"text..."; labelDate.text = date; ..... return cell;} it works correctly. ANY SOLUTION FOR THIS PROBLEM???
