  • UITableView Reusable cells

    - by Michael
    Can someone explain me the way reusable cells works for single table view? How many reusable cells a datasource should create? So far in all samples I've seen only one. Would one even need more?

  • Downloading large files with AFNetworking

    - by goodfella
    I'm trying to implement downloading of a large file and show to user current progress, but block in: -[AFURLConnectionOperation setDownloadProgressBlock:] returns incorrect bytesRead and totalBytesRead values (they are smaller than they should be). For example: If I have a 90MB file and when it downloads completely, latest block invocation in setDownloadProgressBlock: gives me totalBytesRead value about 30MB. On other side, if file is 2MB large, latest block invocation gives correct totalBytesRead 2MB value. AFNetworking is updated to the latest version from github. If AFNetworking can't do it correctly, what solution can I use? Edit: I've determined that even if file is not downloaded completely (and this happens every time with relatively big file) AFNetworking calls success block in: -[AFHTTPRequestOperation setCompletionBlockWithSuccess:failure] I asked a similar question here about this situation, but didn't get any answers. I can check in code downloaded and real file sizes, but AFNetworking has no API for continuation of partial download.

  • className method?

    - by fuzzygoat
    I have just been watching the Stanford iPhone lecture online from Jan 2010 and I noticed that the guy from Apple keeps referring to getting an objects class name using "className" e.g. NSArray *myArray = [NSArray arrayWithObjects:@"ONE", @"TWO", nil]; NSLog(@"I am an %@ and have %d items", [myArray className], [myArray count]); However, I can't get this to work, the closest I can come up with it to use class, is className wrong, did it get removed, just curious? NSArray *myArray = [NSArray arrayWithObjects:@"ONE", @"TWO", nil]; NSLog(@"I am an %@ and have %d items", [myArray class], [myArray count]); Gary

  • UIScrollView - with paging enabled, can I "change" the page width?

    - by Mike McMaster
    What's the simplest way to have a scroll view (with pagingEnabled set to YES) have a page width set to something other than the scroll view's bounds? Let me give an example. Suppose I have a scroll view with 10 items, each 150 pixels wide, and my scroll view is 300 pixels wide. If I start with views 1 and 2 visible and scroll horizontally to the right, I want the next "page" to show items 2 and 3. If I scroll one more page to the right, I would see items 3 and 4. Has anyone done this? If not, what strategy would you use?

  • Creating a unique id for a Core Data program on the iPhone

    - by Big Twisty
    I am fairly new at programming in Objective-C, having been a windows programmer since I was a kid. I am falling in LOVE with it. I am, however, having a bit of trouble figuring out this Core Data stuff. How do I create a new entry with a unique ID? In SQL I would just declare one field as an autoincrement field. I'm not seeing anything like that here, but I could just be missing something. I just want an auto incrementing NSInteger field, so when I manually add items to the database, I will have some form of reference to them.

  • Show image from url in uiimageview

    - by skiria
    I try to show a image in my iphone app but it doesn't show. I connect in IB and I check to show a local image, it workd good. I also check the url from image and it is ok. I use the next code: NSURL *imageURL = [NSURL URLWithString: aVideo.urlThumbnail]; NSData *imageData = [NSData dataWithContentsOfURL:imageURL]; UIImage *image = [UIImage imageWithData:imageData]; imageView.image = image; and //Video.h NSString *urlThumbnail; and this is my code on the view. - (void)viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [tableView reloadData]; } - (void)viewDidLoad { [super viewDidLoad]; NSURL *imageURL = [NSURL URLWithString: aVideo.urlThumbnail]; NSData *imageData = [NSData dataWithContentsOfURL:imageURL]; UIImage *image = [UIImage imageWithData:imageData]; imageView.image = image; }

  • How to get a long url from a short url

    - by JK
    I would like to determine what the long url of a short url is. I have tried using http HEAD requests, but very few of the returned header fields actually contain any data pertaining to the destination/long url. Is there: 1. Any way to determine the long url? 2. If so, can it be done without downloading the body of the destination? Thank you

  • Need a good way to share iPhone source code on the Web.

    - by CJCraft.com
    Hi, I'm looking for a way to share some iPhone SDK source code I have with others. Goals: Share iPhone SDK source code, Objective C written in XCode. I have a good bit of source code I want to share. I'd like for it to be easy. I'd like for it to have syntax highlighting, by this I mean coloring and formatting Ideally it would allow me some room to make it "fit" into my site. I want it to look like basically another page on my site where the content is the code. It shouldn't be just a text file in other words. Here's an example where someone was able to do this for C#: http://www.opennetcf.com/library/sdf/ I guess what I want is the ability to create html documentation for all the classes, etc.

  • Will iPhone OS4 make your life easier or harder as a lone app developer?

    - by Matt
    I am interested to hear what people feel about the new iPhone OS4 release. It is obviously very exciting having access to all the new features, apparently (from apple.com) it has over 1500 new APIs. My original thoughts were "Wow, this is awesome", and I suppose it is. I was just getting comfortable with OS 3.2 development though, and now there is a raft of additional stuff to learn in order to keep up with the pack. So I am feeling quite frustrated! Do you think, when working as an individual app developer, having access to these additional features would improve your applications or just water down the quality? I guess being giving the opportunity to improve applications and provide better features should be welcomed. I think frustration comes from struggling to keep up with the continuous changes, but thats the industry we are in I suppose! Any thoughts/comments?

  • Shuffle Two NSMutableArray independently

    - by Superman
    I'm creating two NSMutableArray in my viewDidLoad, I add it in a NSMutableDictionary. When I tried shuffling it with one array, It is okay. But the problem is when Im shuffling two arrays independently its not working,somehow the indexes got mixed up. Here is my code for my array (I have two of these): self.items1 = [NSMutableArray new]; for(int i = 0; i <= 100; i++) { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES); NSString *documentsDir = [paths objectAtIndex:0]; NSString *savedImagePath = [documentsDir stringByAppendingPathComponent:[NSString stringWithFormat:@"[Images%d.png", i]]; if([[NSFileManager defaultManager] fileExistsAtPath:savedImagePath]){ self.container = [[NSMutableDictionary alloc] init]; [container setObject:[UIImage imageWithContentsOfFile:savedImagePath] forKey:@"items1"]; [container setObject:[NSNumber numberWithInt:i] forKey:@"index1"]; [items1 addObject:container]; } } NSLog(@"Count : %d", [items1 count]); [items1 enumerateObjectsUsingBlock:^(id object, NSUInteger index, BOOL *stop) { NSLog(@"%@ images at index %d", object, index); }]; then my shuffle code(Which I tried duplicating for the other array,but not working also): srandom(time(NULL)); NSUInteger count = [items1 count]; for (NSUInteger i = 0; i < count; ++i) { int nElements = count - i; int n = (random() % nElements) + i; [items1 exchangeObjectAtIndex:i withObjectAtIndex:n]; } How am I going to shuffle it using above code (or if you have other suggestions) with two arrays? Thanks My other problem is when I tries subclassing the class for the shuffle method or either use the above code, their index mixed. For example: Object: apple, ball, carrots, dog Indexes: 1 2 3 4 but in my View when shuffled: Object: carrots, apple, dog, balle Indexes: 2 4 1 3

  • How can we set time delay in animation of images to make them appear smooth ?

    - by srikanth rongali
    Hi, I have 10 CCSprite images. They are continues images. I am using, CCSprite *playerH = [CCSprite spriteWithFile:@"Player_01.png" ]; playerH.position = ccp(playerH.contentSize.width/2, windowSize.height/2); [self addChild:playerH z:1]; CCAnimation* animation = [CCAnimation animationWithName:@"dance" delay:0.20f]; for( int i = 1; i < 11; i++ ) { [animation addFrameWithFilename: [NSString stringWithFormat:@"Player_%02d.png", i]]; } NSLog(@"k VALUE: k: %d",k); id actionA = [CCAnimate actionWithAnimation: animation restoreOriginalFrame:NO]; id actionD = [CCDelayTime actionWithDuration:5.0f]; id actionC = [CCCallFunc actionWithTarget:self selector:@selector(enemyEntranceScreen:)]; id seqActionPlayer = [CCSequence actions:actionA, actionD, actionC, nil]; [playerH runAction: seqActionPlayer]; But the animation is not continues. I have changed the animation delay time. but, I can see only three images appearing. How can we know how much time interval should we keep in animation. Is there any relationship between this and the frame rate [[CCDirector sharedDirector] setAnimationInterval:1.0/60]; [[CCDirector sharedDirector] setDisplayFPS:YES]; Thank you.

  • I need help to debug my XML parsing please

    - by Griffo
    I'm parsing this line: <type>branch</type> with this code if ([elementName isEqualToString:@"type"]) { [currentBranchDictionary setValue:currentText forKey:currentElementName]; } When I test the value in the type key, it does not contain branch but instead it contains branch\n. Here is the test I'm performing: if ([[currentBranchDictionary valueForKey:@"type"] isEqualToString:@"branch"]) { NSLog(@"no new-line"); } else if ([[currentBranchDictionary valueForKey:@"type"] isEqualToString:@"branch\n"]) { NSLog(@"new-line"); } this returns the "new-line" output I don't understand where the carriage return is being added, can anyone help?

  • First and last UITableViewCell keep changing while scrolling.

    - by W Dyson
    I have a tableView with cells containing one UITextField as a subview for each cell. My problem is that when I scroll down, the text in the first cell is duplicated in the last cell. I can't for the life if me figure out why. I have tried loading the cells from different nibs, having the textFields as ivars. The UITextFields don't seem to be the problem, I'm thinking it has something to do with the tableView reusing the cells. The textFields all have a data source that keeps track of the text within the textField and the text is reset each time the cell is shown. Any ideas? UPDATE: Thanks guys, here's a sample: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSLog(@"Section %i, Row %i", indexPath.section, indexPath.row); static NSString *JournalCellIdentifier = @"JournalCellIdentifier"; UITableViewCell *cell = (UITableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:JournalCellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:JournalCellIdentifier] autorelease]; cell.selectionStyle = UITableViewCellSelectionStyleNone; cell.accessoryType = UITableViewCellAccessoryNone; } if (indexPath.section == 0) { UITextField *textField = (UITextField *)[self.authorCell viewWithTag:1]; [cell addSubview:textField]; self.authorTextField = textField; self.authorTextField.text = [self.textFieldDictionary objectForKey:@"author"]; NSLog(@"Reading Author:%@", [self.textFieldDictionary objectForKey:@"author"]); } else if (indexPath.section == 1) { UITextField *textField = (UITextField *)[self.yearCell viewWithTag:1]; [cell addSubview:textField]; self.yearTextField = textField; self.yearTextField.text = [self.textFieldDictionary objectForKey:@"year"]; NSLog(@"Reading Year:%@", [self.textFieldDictionary objectForKey:@"year"]); } else if (indexPath.section == 2) { UITextField *textField = (UITextField *)[self.volumeCell viewWithTag:1]; [cell addSubview:textField]; self.volumeTextField = textField; self.volumeTextField.text = [self.textFieldDictionary objectForKey:@"volume"]; NSLog(@"Reading Volume:%@", [self.textFieldDictionary objectForKey:@"volume"]); } return cell; }

  • Setting shadowColor with property syntax gives compiler error: Expected identifier before '[' token.

    - by sam
    I have an iPad app in which I'm setting the shadow color of a UILabel in a UIView's initWithFrame: method. When I use the following syntax: m_label.shadowColor = [UIColor colorWithWhite:1.0 alpha:0.5]; I get this compiler error: Expected identifier before '[' token However, when I use the following syntax: [m_label setShadowColor:[UIColor colorWithWhite:1.0 alpha:0.5]]; It compiles without complaint. Using property syntax for other properties of the UILabel is working fine (shadowOffset, autoresizingMask, backgroundColor, font, textColor, etc.). Incidentally, I get the same error message when the statement is simply this: m_label.shadowColor; Whereas this, for example, gives no error: m_label.shadowOffset; FWIW, the entire method looks like this: #define shadowColor [UIColor colorWithWhite:1.00 alpha:0.5] #define selectedColor [UIColor colorWithWhite:0.25 alpha:1.0] #define unselectedColor [UIColor colorWithWhite:0.45 alpha:1.0] #define CLOSEBUTTON_WIDTH 26.0 #define CLOSEBUTTON_HEIGHT 26.0 - (id)initWithFrame:(CGRect)frame { if ((self = [super initWithFrame:frame])) { m_imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0, 0.0, self.frame.size.width, self.frame.size.height)]; m_imageView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; m_imageView.backgroundColor = [UIColor clearColor]; m_imageView.image = [[UIImage imageNamed:@"tab.png"] stretchableImageWithLeftCapWidth:8.0 topCapHeight:0.0]; m_imageView.highlightedImage = [[UIImage imageNamed:@"tabSelected.png"] stretchableImageWithLeftCapWidth:8.0 topCapHeight:0.0]; m_label = [[UILabel alloc] initWithFrame:CGRectZero]; m_label.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; m_label.backgroundColor = [UIColor clearColor]; m_label.font = [UIFont boldSystemFontOfSize:12.0]; m_label.textColor = unselectedColor; m_label.shadowOffset = CGSizeMake(0.0, 1.0); m_label.shadowColor = shadowColor; // Expected identifier before '[' token [m_label setShadowColor:shadowColor]; m_closeButton = [[UIButton alloc] initWithFrame:CGRectMake(9.0, 1.0, CLOSEBUTTON_WIDTH, CLOSEBUTTON_HEIGHT)]; [m_closeButton setBackgroundImage:[UIImage imageNamed:@"tabClose.png"] forState:UIControlStateNormal]; [m_closeButton addTarget:self action:@selector(closeTab) forControlEvents:UIControlEventTouchUpInside]; [self addSubview:m_imageView]; [self addSubview:m_label]; [self addSubview:m_closeButton]; self.backgroundColor = [UIColor clearColor]; } return self; } Any ideas?

  • Adding methods to an Objective C class interface is optional?

    - by Steve the Plant
    Coming from a C++ background, one thing that confuses me about Objective C is the fact that you can add a method to a class without actually specifying it in the class interface. So I had a barrage of questions: Why would someone choose to not add the method in the class interface? Is it simply because of visibility? Methods without a declaration in the interface are private? Is declaring methods in a class interface just optional? Is it different for overriding a base class' method?

  • Does this popup view violate HIGS?

    - by brettr
    Will using a popup view to present a comment submission form violate the HIGS? I may have one popup with selections that goes to the final popup. Two popups back to back. This is more similar to a modal type of view than an alert or action sheet as described by the HIGS: http://developer.apple.com/iphone/library/documentation/UserExperience/Conceptual/MobileHIG/ModalViews/ModalViews.html#//apple_ref/doc/uid/TP40006556-CH11-SW1 under the section 'Using Modal Views'. Basically the type of view I'm shooting for is a combination of an alert with a custom view. It's sort of a mini view since it will be centered in the middle of the screen but not take up all of the viewing area. I'm fairly sure that is a violation however, but I'm looking for a few opinions on it. I believe what needs to happen is use a modal view, which will cover the entire view.
