  • Populating cell in UITableView with unique items

    - by aahrens
    I have an array of URL Links that I'm trying to load into a Grouped UITableView. The goal being that I have numberOfSectionsInTableView return [url count] so I can have number of sections equal to the number of url links. Then in numberOfRowsInSection returns 1 so I only populate 1 URL for each section. The trouble I'm having is to ensure that cellForRowAtIndexPath won't keep grabbing the first url link. I suspect it's because it's always grabbing the first url because the rowIndex is always zero. Any ideas how to ensure that each cell in my UITableView is populated with a different url link? - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return [newsItems count]; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 1; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease]; cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease]; cell.textLabel.lineBreakMode = UILineBreakModeWordWrap; cell.textLabel.numberOfLines = 5; } // Configure the cell. Get the title of the news item that was parsed out int newsItemIndex = [indexPath indexAtPosition: [indexPath length] - 1]; [cell.textLabel setText:[[newsItems objectAtIndex: newsItemIndex] objectForKey: @"link"]]; return cell; }

  • convert string to date and write back into NSMutableArray

    - by padatronic
    I have a NSMutableArray I get by loading a plist into it. The date field comes in as a string and i want to change it into a nsdate. I can change an nsstring into an nsdate. My array is an array of objects like the one below; { Date = "1/1/2009" Description = "Have you ever looked at a badger and thought i wonder how far you could fire that out of a cannon? Well this talk is for you"; File = "http://www.badgerCannon.org.uk/mp3/070310pm.mp3"; Series = "The Badger planet"; Speaker = "Will Ferell"; Title = "Is it a bird, is it a plane? no its a badger"; } I loop through and pull out the date and convert it from a NSString to a NSDate. I try writing it back in using the code; [[self.MediaDataArray objectAtIndex:i] replaceObjectAtIndex:0 withObject:Date]; but it errors and i am pretty sure it is because i am not putting it back into the array in the same format, ie just as a date not as date = "date". But lets face it i don't really know! Am i barking up the wrong tree? Please help, i have got the coding equivalent of writters block, or alternatively am just being really stupid! thanks in advance

  • How to change a grouped UITableView cell's background to black (or non-white)?

    - by Meltemi
    Just want to make sure I'm not overlooking something obvious... It seems like it should be trivial to set the background color (black is fine) of a UITableView's cell to something other than white or completely transparent so that you can display your data with white text. However, with my attempts I lose the corners on my grouped table view and it all looks like crap. I've seen & understand the methods described by Matt Gallagher about customizing TableView cells with exotic gradients, etc. but wanted to be certain before heading down that path...

  • Why I add the CGPoint in the NSMultable Array?

    - by Tattat
    I want to store my CGPoint to the NSMultable Array, so , I have method like this: [self.points addObject:CGPointMake(x, y)]; But I got the error, it said that : Incompatible type for argument 1 of "addObject". So, I check out the API, (void)addObject:(id)anObject anObject The object to add to the end of the receiver's content. This value must not be nil. So, I think the "CGPointMake" can make a Object, but it can't be assigned. What happens?

  • Transparent Background with a Modal UIViewController

    - by Mick Walker
    I have a dilema, I want to present to the user a semi-transparent view. I found out by experimenting that if I simply pushed the transparent view to the top of my NavigationController's stack, that it would not render the transparency level I wanted. So I decided to simply add the view as a subview of the current view at the top of the stack. This solution works, the view below is still visible, and the View is 'semi-modal'. The problem is, if the parent view inherits from UITableViewController (as mine does), then the view I 'push' onto it, does not cover the navigation bar at the top. I really don't want to get into a situation where I am forced to enable / disable controls on the navigation bar every time I push this view, so I was wondering, if anyone knew of any solutions that I could use so that the view I push onto the UITableViewController will actually 'push over' the navigation bar?

  • Is there a difference between only <NSXMLParserDelegate>, only setDelegate method, or the use of bot

    - by gotye
    Hey, I noticed that when I do this : [myParser setDelegate:self]; it works :D (even if I didn't add the code in the header file ... you know, the <delegateStuff, delegateOtherStuff> in the interface declaration) When are you supposed to modify the header file to make your delegate work ? Is the setDelegate method enough to make it work ? Cheers for any help ;) Gauthier

  • I need to load a video stored in Applications folder in to a UITableView ?

    - by srikanth rongali
    I need to load a video stored in Applications folder in to a table view. When I touched the cell the video plays. I used the following code to get all the video files in to an array. NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray* contents = [fileManager directoryContentsAtPath:@"/Users/srikanth/Desktop/Projects/UF/Table2/Videos"]; for(a = 1; a < [contents count]; a++) NSLog(@"Array contents: %@", [contents objectAtIndex:a]); cells = [[NSMutableArray alloc]initWithCapacity:[contents count]]; But how can I load the videos into UITableView. I used NSBundle for loading videos by giving path. It worked. But, now I need the videos to load from the array contents. When I touch the cell of the table the corresponding file from the array contents si to be loaded. How can I make it? Thank you.

  • To store images from UIGetScreenImage() in NSMutable Array

    - by sujyanarayan
    Hi, I'm getting images from UIGetScreenImage() and storing directly in mutable array like:- image = [UIImage imageWithScreenContents]; [array addObject:image]; [image release]; I've set this code in timer so I cant use UIImagePNGRepresentation() to store as NSData as it reduces the performance. I want to use this array directly after sometime i.e after capturing 1000 images in 100 seconds. When I use the code below:- UIImage *im = [[UIImage alloc] init]; im = [array objectAtIndex:i]; UIImageWriteToSavedPhotosAlbum(im, nil, nil, nil); the application crashes. And I dont want to use UIImagePNG or JPGRepresentation() in timer as it reduces performance. My problem is how to use this array so that it is converted into image. If anybody has idea related to it please share with me. Thanks in Advance.

  • is there a way to show Uitableviewcell selection on limited frame?

    - by Rahul Vyas
    i have a uitableview cell added some labels something like this - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; UIImage* myImage = [UIImage imageNamed:@"AccessoryForDealsMain.png"]; UIImageView *MyimageView = [[UIImageView alloc] initWithImage:myImage]; MyimageView.contentMode=UIViewContentModeScaleToFill; cell.accessoryView=MyimageView; [MyimageView release]; UILabel *BluePatti = [[UILabel alloc] init]; BluePatti.frame=CGRectMake(0,0,4,44); BluePatti.backgroundColor = BLUEPATTI;//[UIColor blueColor]; UILabel *BlackLine = [[UILabel alloc] init]; BlackLine.frame=CGRectMake(3,0,1, 45); BlackLine.backgroundColor = BLACK_LINE; [BluePatti addSubview:BlackLine]; [BlackLine release]; [cell.contentView addSubview:BluePatti]; [BluePatti release]; UILabel *Seperator = [[UILabel alloc] initWithFrame:CGRectZero]; Seperator.backgroundColor = [UIColor colorWithRed:234/256.0 green:234/256.0 blue:234/256.0 alpha:1.0]; //[UIColor lightGrayColor]; Seperator.frame = CGRectMake(4,43,316,1); [cell.contentView addSubview:Seperator]; [Seperator release]; } if(indexPath.section==5) { cell.textLabel.text=[self.GenderCellData objectAtIndex:indexPath.row]; cell.textLabel.textColor=CELL_TEXT_COLOR; cell.textLabel.font=CELL_FONT; } else { cell.textLabel.text=@"Cells"; cell.textLabel.font=CELL_FONT; } return cell; } now when i touch cell it shows blue selection above all subviews.How do i change selection frame and colour?

  • Core Data (NSFetchedResultsController) displaying one row per section

    - by Urizen
    I have a CoreData application which uses NSFetchedResultsController. NSFetchedResultsController is useful in that it allows me to access the fetched objects more easily etc. but I find that I have problems with the following: I get a crash when I display a single row for each section (irrespective of the number of actual rows present) as a summary of the information in that section (e.g. showing a statistical analysis of the data contained in the fetched rows for that section). I understand that the NSFetchedResultsControllerDelegatemethods have to agree with the number of rows reported per section by the UITableView Delegate method but I would like to be able to fetch all of the records for each section without necessarily displaying each of the rows. The above causes me inconsistency crashes, when I try to insert or delete data for a section, which reports that the number of rows for each section is not as it should be given the number of insertions/deletions. Is there any way I can do what I'm trying to achieve? Thanks for any help.

  • contentoffset during flick gesture

    - by Michael Xu
    Hi all, Does anyone else notice that the contentOffset of UIScrollView doesnt update during a flick gesture? It only updates after the flick gesture has totally completed, when the flick gesture is finished. After the finger has left the screen, the scrollview keeps moving, in the decelerating phase. but this isnt reflected in the contentOffset of the UIScrollView. Is there a way to track where the contentOffset is during the decelerating part of the flick gesture? I have an OpenGL layer on top, and i want it to move with the scrollView. Can't seem to get the right info out of the scrollview though... Thoughts? thanks, michael

In addition to this, is there some notification I can subscribe to that returns the NSRange of the selected body of text once it is selected? Thanks for any help!

    Hello everyone: I hope to get the http header info(file size) in asynchronous mode. So I initialize as codes: [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(processReadResponseHeaders:) name:@"readResponseHeaders" object:nil]; my codes to read the http header -(void)processReadResponseHeaders: (ASIHTTPRequest *)request ;//(id)sender; { unsigned long long contentLength = [request contentLength]; //error occurs here } It has to change the source code of ASIHTTPRequest.m I did add my codes in function readResponseHeaders to notify the event is triggered ) - (void)readResponseHeaders { //.........................

  • Playing a .TS file on iOS

    - by Jonathan Grynspan
    We're working with some hardware that produces files in the .TS format, and we'd like to play them on an iOS device. (The files are internally consistent with what iOS supports--MPEG-4 video, AAC audio.) We've been investigating three options so far: Roll our own integrated HTTP Live Streaming server and serve up a faux M3U8 playlist from within the app. This... doesn't seem to want to play nice, and we've had mixed luck actually getting the .TS files to play on devices. Unwrap the MPEG-4 and AAC data from the TS file and re-wrap it as MP4. This, I'm told, is exceedingly difficult to do, and I haven't found anything useful online that could shed light on how to do it. We've got code in the pipeline to do it but it won't be ready until long after we need it. If we could do it, I could easily subclass NSURLProtocol and have it working within a matter of hours minutes. Use FFmpeg to implement option #2. FFmpeg seems like a possible solution but it isn't configured to build for iOS and I don't have the background to get it working (whereas the rest of our engineers don't have the Apple background needed.) I think #2 is our best bet, but as I don't know the ins and outs of MPEG-2 TS and MPEG-4, I don't have the ability to put it together myself. Does anybody have any insight into this problem? Perhaps some experience playing local TS files on iOS, or some tips on converting from TS to MP4?

  • How to Unload a popped view controller?

    - by RexOnRoids
    Using a navigation based view hierarchy. I have a root view controller, and multiple view controllers that branch out from the same when a button is pressed. When a user presses the back button on the UINavigationBar, the current viewcontroller is popped and the display animates back to the rootviewcontroller. The problem is, I want the viewcontrollers to UNLOAD whenever they are popped. Seems like they are not unloading because when I go back to them they are still in the state they were when they were popped. How do I unload the viewcontrollers after navigating back to the rootviewcontroller?
