  • Oracle access from iOS

    - by Michael Lowman
    I'm developing an iPad app that needs read-only access to an Oracle database. Is there any way to do this? As far as I can see, the only options are using OCI, which requires a prebuilt binary in the form of the instant client (and not built for ARM), or OJDBC drivers. Both of these seem to be out of the question. In my research I have discovered that libmysqlclient compiles for arm with minimal tuning. This is a stretch, but is there any possible way to use this to my advantage? I have seen this product providing odbc connectivity through the use of a Windows gateway machine using the ODBC client libraries, but this solution really isn't an option for me at the present time. Any ideas?

  • Very very weird problem with UIImageView property - I can access it then I can't, and it's not nil.

    - by just_another_coder
    Very very weird problem with UIImageView property on iPad application @interface MyViewController : UIViewController { IBOutlet UIImageView* coverImage; } @property(nonatomic, retain) IBOutlet UIImageView* coverImage; … more code @implementation MyViewController @synthesize coverImage; … more code - (void)viewDidLoad { [super viewDidLoad]; NSString* imageName = @"my_image.png"; UIImage* tempImage = [UIImage imageNamed:imageName]; [self.coverImage setImage:tempImage]; } The above code WILL display the image. In another part of code: -(IBAction) stopButtonPressed:(id)sender { [self.coverImage setHidden:YES]; NSLog(@"coverImage desc: %@", [coverImage description]); } The image will NOT disappear. I know the reference to the image isn't nil, because it gives me this output: 2010-05-29 17:37:40.706 MyApp[95360:207] coverImage desc: UIImageView: 0x5128420; frame = (0 0; 1024 768); autoresize = RM+BM; userInteractionEnabled = NO; layer = CALayer: 0x512bed0 In addition, if I move the code in viewDidLoad to another part of the class, and try to execute it from there, it fails to show the image at all.

  • Dynamically creating subviews of similar type

    - by Akki
    My code for above view is: -(void)viewWillAppear:(BOOL)animated{ float yh = 0; while (yh<200) { //UIView CGRect myFrame = CGRectMake(0, yh, 320, 30); UIView *myFirstView = [[UIView alloc] initWithFrame:myFrame]; myFirstView.backgroundColor = [UIColor orangeColor]; //IUILabel in UIView CGRect mylblFrame = CGRectMake(5, yh, 60, 15); UILabel *lblsize = [[UILabel alloc] initWithFrame:mylblFrame]; lblsize.text = @"Hello"; [myFirstView addSubview:lblsize]; CGRect mylbl_hi = CGRectMake(80, yh, 60, 15); UILabel *lbl_hi = [[UILabel alloc] initWithFrame:mylbl_hi]; lbl_hi.text = @"Hii"; [myFirstView addSubview:lbl_hi]; [self.view addSubview:myFirstView]; [lbl_hi release]; [lblsize release]; [myFirstView release]; yh=yh+40; } [super viewWillAppear:YES]; } I can't understand reason of it being like this...i wanted labels to be attached with my subviews of orange color...this may be odd day for me to understand what's wrong with my code...if any of you can tell me where i ma doing wrong would be great to me. This is my first time creating view programmatically..so please excuse me if all this is silly question

  • iOS Core Data migration: moving something from an entity into a file

    - by Tim Sullivan
    I have a scenario where I'm moving the contents of a blob stored in a core data entity into a file. I need a way to export that data during a migration, where I know the entity that's being converted and save the blob to a file, writing the location of that file into the converted entity's appropriate attribute. I can't seem to find a way to do this. The docs regarding the Three Stage Migration seem to indicate what can be done, but I'm not sure where to define things, or what exactly to define.

  • How to animate the frame of an layer with CABasicAnimation?

    - by mystify
    I guess I have to convert the CGRect into an object to pass it to fromValue? This is how I try it, but it doesn't work: CABasicAnimation *frameAnimation = [CABasicAnimation animationWithKeyPath:@"frame"]; frameAnimation.duration = 2.5; frameAnimation.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]; frameAnimation.fromValue = [NSValue valueWithCGRect:myLayer.frame]; frameAnimation.toValue = [NSValue valueWithCGRect:theNewFrameRect]; [myLayer addAnimation:frameAnimation forKey:@"MLC"];

  • Using NSUserDefaults to load data depending on which table view cell is pressed

    - by Bad_APPZ
    I want my app to work just like the 'contacts' app on iOS. When a user selects a certain TableViewCell, i want to load certain data. No Matter which cell is pressed, Either "Joseph, Richard, or Shannon", This view comes up: Both of the views look the exact same, but they just display different information. So i guess my question is: How can I programmatically set a key @"cell1" @"cell2", etc... for each cell using NSUserDefaults? But here is the catch, I dont know how many cells will be added, so i cant hard code this, How can I create a key for each table view cell for how ever many is added? Thanks for the help!

  • 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.

  • Creating Actions from UIActionSheets help

    - by user337174
    I am using two UIAction sheets within my current project. I can get one to work perfectly fine but when i insert a second action sheet it runs the same arguements as the first. How do i define the actionsheets seperatly? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *actionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; actionSheet.actionSheetStyle = UIActionSheetStyleDefault; [actionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [actionSheet release]; } -(IBAction) mapButtonClicked:(id)sender { // open a dialog with just an OK button UIActionSheet *mapActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Map"],nil]; mapActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [mapActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [mapActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } }

  • Switching between TabBarController Views when event fired

    - by aahrens
    I have a UITabBarController with two different views to switch between. What I would like to do is when a button is clicked in View1 to switch directly to View2. Then in View2 if they click a button it switches them to View1. It transfers between View1 and View2 when the click on the tabBarController fine but I'm trying to perform the switching for them when an event occurs Is there a way to do this by calling a method on my UITabBarController? @interface CalcAppDelegate : NSObject <UIApplicationDelegate> { UITabBarController *tabBarController; }

  • Warning generated by UIButton setting code

    - by Spider-Paddy
    I have a for loop setting the background images on buttons, basically the buttons are thumbnail previews of different items & can't be set statically, however the code gives an warning because it runs through all the UIViews but then calls setBackgroundImage which does not apply to all views. The warning is an irritation, I understand what it's complaining about, how can I get rid of it? (I don't want to turn off the warning, I want to fix the problem) // For loop to set button images for (UIView *subview in [self.view subviews]) // Loop through all subviews { // Look for the tagged buttons, only the 8 tagged buttons & within array bounds if((subview.tag >= 1) && (subview.tag <= 8) && (subview.tag < totalBundles)) { // Retrieve item in array at position matching button tag (array is 0 indexed) NSDictionary *bundlesDataItem = [bundlesDataSource objectAtIndex:(subview.tag - 1)]; // Set button background to thumbnail of current bundle NSString *picAddress = [NSString stringWithFormat:@"http://some.thing.com/data/images/%@/%@", [bundlesDataItem objectForKey:@"Nr"], [bundlesDataItem objectForKey:@"Thumb"]]; NSURL *picURL = [NSURL URLWithString:picAddress]; NSData *picData = [NSData dataWithContentsOfURL:picURL]; // Warning is generated here [subview setBackgroundImage:[UIImage imageWithData:picData] forState:UIControlStateNormal]; } }

  • NSURLConnection shown as leaking in instruments

    - by Gyozo Kudor
    Hello another stupid question regarding leaks and also NSURLConnection. How do i release it? Is it enough if i release in the following 2 methods? (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error (void)connectionDidFinishLoading:(NSURLConnection *)connection Because in instruments it shows me the line where I alloc my connection as the source of leaking. OK I don't get it. After the following code my urlConnection has a retain count of 2. WTF? NSURLConnection *urlConnection = [[NSURLConnection alloc] initWithRequest: urlRequest delegate: self]; This is the line that instruments points me to. I find this very weird.

  • How to animate a UIButton selected background Image

    - by Thomas Joos
    hi all, I have a class defining a custom UIButton. I configurate a normal and selected state like this: //custom image UIImage *image = [UIImage imageNamed:@"customIconCreationBG.png"]; UIImage *stretchImage = [image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImage forState:UIControlStateNormal]; UIImage *imageSelected = [UIImage imageNamed:@"customIconCreationBG_selected.png"]; UIImage *stretchImageSelected = [imageSelected stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0]; [self setBackgroundImage:stretchImageSelected forState:UIControlStateSelected]; In another class I'm filling an array with custom buttons and i'm adding a button pressed method. It sets the selected state to TRUE -(void)buttnPressed:(id)sender { NSLog(@"button pressed"); [[NSNotificationCenter defaultCenter] postNotificationName:@"unselectBGIcons" object:self]; HorizontalListIcon *pressedIcon = ((HorizontalListIcon *)sender); [pressedIcon setSelected:TRUE]; } The button switches to another background, which is great. Is there a way to animate this change ( fading in? ) because it's a bit hard now. Greets

  • Struggling with a loop

    - by Emil
    Hey. I am trying to make an integer match another integer by adding a number to one of them. I have tried several loop types, but none has worked. Take a look at the code: int favoriteLoop = [favoriteThing intValue]; if (favoriteLoop != [[[array objectAtIndex:favoriteLoop] description] intValue]){ NSLog(@"%d", [[[array objectAtIndex:favoriteLoop] description] intValue]); int favTemp = favoriteLoop; for (int x = favTemp; (favoriteLoop == [[[array objectAtIndex:favoriteLoop] description] intValue]); x++) { NSLog(@"Still not there.."); } } Could anyone help me clear up this mess? It just won't work! Could it have something to do with it allready being inside a for-loop?

  • Is there any reason why someone would want to create an Core Data model programmatically?

    - by mystify
    I wonder in which cases it would be good to make an NSManagedObjectModel completely programmatically, with NSEntityDescription instances and all this stuff. I'm that kind of person who prefers to code programmatically, rejecting Interface Builder. But when it comes to Core Data, I have a hard time figuring out why I should kill my time NOT using the nice Xcode Data Modeler tool. And since data models are stuck to a given state (except when you want to do some ugly migration operations where thinks probably go wrong and users get mad, really mad), I see no big sense in a data model that's made programmatically for the purpose of changing it all the time. Did I miss something?

  • Programatically created UITableViewCell subclass only working on highlight

    - by squarefrog
    I've created a subclass of UITableViewCell but I'm struggling to get it to work properly. If I use UITableViewStyleDefault then the class only works when highlighted. If I use UITableViewStyleValue1 then it mostly works but I'm unable to change label fonts much. I tried researching but it seems everyone is doing this via a .xib file, but not programatically. Implementation file #import "ASCustomCellWithCount.h" @implementation ASCustomCellWithCount @synthesize primaryLabel,secondaryLabel,contentCountImage,contentCount; - (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier { self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]; if (self) { // Initialization code contentCountImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed: @"tableCount.png"] ]; primaryLabel = [[UILabel alloc] init]; primaryLabel.textAlignment = UITextAlignmentLeft; primaryLabel.textColor = [UIColor blackColor]; primaryLabel.font = [UIFont systemFontOfSize: 20]; primaryLabel.backgroundColor = [UIColor clearColor]; secondaryLabel = [[UILabel alloc] init]; secondaryLabel.textAlignment = UITextAlignmentLeft; secondaryLabel.textColor = [UIColor blackColor]; secondaryLabel.font = [UIFont systemFontOfSize: 8]; secondaryLabel.backgroundColor = [UIColor clearColor]; contentCount = [[UILabel alloc] init]; contentCount.textAlignment = UITextAlignmentCenter; contentCount.font = [UIFont boldSystemFontOfSize: 15]; contentCount.textColor = [UIColor whiteColor]; contentCount.shadowColor = [UIColor blackColor]; contentCount.shadowOffset = CGSizeMake(1, 1); contentCount.backgroundColor = [UIColor clearColor]; [self.contentView addSubview: contentCountImage]; [self.contentView addSubview: primaryLabel]; [self.contentView addSubview: secondaryLabel]; [self.contentView addSubview: contentCount]; } return self; } - (void)layoutSubviews { [super layoutSubviews]; CGRect contentRect = self.contentView.bounds; // CGFloat boundsX = contentRect.origin.x; primaryLabel.frame = CGRectMake(0 ,0, 200, 25); secondaryLabel.frame = CGRectMake(0, 30, 100, 15); contentCount.frame = CGRectMake(contentRect.size.width - 48, contentRect.size.height / 2 - 13, 36, 24); contentCountImage.frame = CGRectMake(contentRect.size.width - 48, contentRect.size.height / 2 - 12, 36, 24); } - (void)setSelected:(BOOL)selected animated:(BOOL)animated { [super setSelected:selected animated:animated]; // Configure the view for the selected state } - (void)dealloc { [primaryLabel release]; [secondaryLabel release]; [contentCountImage release]; [contentCount release]; } @end And then to create the cell I use - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; ASCustomCellWithCount *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[ASCustomCellWithCount alloc] initWithStyle: UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = [NSString stringWithFormat:@"%@", [tempArray objectAtIndex: indexPath.row]]; cell.contentCount.text = @"49"; return cell; }

  • Tab-Bar not hiding on all views

    - by Sheehan Alam
    I have a tab-bar controller that loads a RootView. The RootView has 4 buttons that will load a UITableView I don't want my tab-bar to be visible in the RootView so I added the following code: -(void)viewDidLoad{ self.hidesBottomBarWhenPushed = YES; } When I initially load the app the tab-bar doesn't appear, but when I click on a button, and go back to the RootView the tab-bar still appears. I have tried placing this code in viewWillAppear and other application lifecycle methods but no luck.
