  • Responding to setters

    - by Simon Cave
    What is the best way to respond to data changes when property setters are called. For example, if I have a property called data, how can I react when [object setData:newData] is called and still use the synthesised setter. Instinctively, I would override the synthesised setter like so: - (void)setData:(DataObject *)newData { // defer to synthesised setter [super setData:newData]; // react to new data ... } ...but of course this doesn't make sense - I can't use super like this. So what is the best way to handle this situation? Should I be using KVO? Or something else?

  • iPhone keyboard, Done button and resignFirstResponder

    - by nevan
    This is probably a dumb question, but I can't find the answer in the docs. Did the "Done" button on the pop-up keyboard always cause the keyboard to disappear? I see a lot of code around the web like this: - (BOOL)textFieldShouldReturn:(UITextField *)theTextField { [theTextField resignFirstResponder]; return YES; } When I press the "Done" button, the keyboard pops down and the UITextField resigns first responder. I'm presuming that pressing the "Done" button didn't used to cause a UITextField to resignFirstResponder, but that behavior changed at some time. I'm debugging on OS 3.0 - 3.1.3

  • iOS iPad Master Detail template can't interact with detail view

    - by CraigularB
    I have an iPad app generated from the Master-Detail template in XCode. The iPad Storyboard has under the Detail View Controller a View that holds a ScrollView which holds an ImageView. In the DetailViewController.m file I added the following code to allow the ScrollView to move and zoom the image: -(UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return self.comicImage; } This works great on the iPhone (it's a universal app) but not the iPad; I can scroll and zoom the image on the iPhone no problem, but on the iPad it's like the ScrollView isn't responding to the touches, and I can't figure out how to pass the touches on to the ScrollView. I've already deactivated the popover controller from appearing with a right swipe like this: self.splitViewController.presentsWithGesture = NO; How do I make it so the user can interact with the ScrollView in the DetailViewController?

  • iOS UIImageView dataWithContentsOfURL returning empty

    - by user761389
    I'm trying to display an image from a URL in a UIImageView and I'm seeing some very peculiar results. The bit of code that I'm testing with is below imageURL = @"http://images.shopow.co.uk/image/user_dyn/1073/32/32"; imageURL = @"http://images.shopow.co.uk/assets/profile_images/default/32_32/avatar-male-01.jpg"; NSURL *imageURLRes = [NSURL URLWithString:imageURL]; NSData *imageData = [NSData dataWithContentsOfURL:imageURLRes]; UIImage *image = [UIImage imageWithData:imageData]; NSLog(@"Image Data: %@", imageData); In it's current form I can see data in the output window which is what I'd expect. However if comment out the second imageURL so I'm referencing the first I'm getting empty data and therefore nil is being returned by imageWithData. What is possibly more confusing is that the first image is basically the same as the second but it's been through a PHP processing script. I'm nearly certain that it isn't the script that's causing the issue because if I use this instead imageURL = @"http://images.shopow.co.uk/image/product_dynimg/389620/32/32" the image is displayed and this uses the same image processing script. I'm struggling to find any difference in the images that would cause this to occur. Any help would be appreciated.

  • Can I refer to NSDictionary items numerically?

    - by cannyboy
    I'm trying to set up a UITableView which acts as a form. Each cell has within it a UILabel and a UITextField, so one cell is: Name <enter name> ^ ^ UILabel UITextField Now, I'm trying to populate the UILabel and the UITextField from a NSDictionary (from a plist), where it's organized like so: Root Type Value Name String Address String City String etc But in order to get the right labels and textfields in the cellForRowAtIndexPath method, I would have to refer to the Dictionary numerically. Is there any way to do that?

  • UIActionSheet Cancel button keeps crashing my app

    - by user337174
    I am really puzzeled by this one. I have set up two UIActionSheets in my application. They work perfectly fine until you use the cancel button in the UIActionSheets. When i navigate away from the page the UIAactionSheet returns too it crashes my app. Does anyone have any ideas as too why? -(IBAction) phoneButtonClicked:(id)sender { // open a dialog with just an OK button phoneActionSheet = [[UIActionSheet alloc] initWithTitle:nil delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:[NSString stringWithFormat:@"Phone: %@",phone],nil]; phoneActionSheet.actionSheetStyle = UIActionSheetStyleDefault; [phoneActionSheet showInView:self.view]; // show from our table view (pops up in the middle of the table) [phoneActionSheet release]; } -(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (actionSheet == phoneActionSheet) { if(buttonIndex == 0){ NSString *callPhone = [NSString stringWithFormat:@"tel:%@",phone]; NSLog(@"Calling: %@", callPhone); [[UIApplication sharedApplication] openURL:[NSURL URLWithString:callPhone]]; } } }

  • Cocoa Scripting Bridge and <contents> element

    - by Stephen
    So, the application I'm trying to script has a scripting definition file that includes a <contents> element, which is an "implicitly specified container." The question, how do I get at what's inside this element using Scripting Bridge? Or alternatively, how do I send the Apple Event necessary to retrieve it and then transform what I get back into an SBObject? I already tried: [document nameOfKey] document.nameofKey [document contents] document.contents

  • NSCFType keeps occurring, something is not being released?

    - by user1493543
    I'm attempting to delete files from the documents directory using a tableview/array combination. For some reason, my NSString pointing to the Documents directory path is being converted to a NSCFType (which after some research, I understand is happening because a variable is not being released). Because of this, the application crashes at the line NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; claiming that NSCFType cannot recognize the method stringByAppendingPathComponent. I would appreciate if someone could help me out (I hope I have explained this clearly enough). - (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { NSString *temp = [directoryContent objectAtIndex:indexPath.row]; NSLog(temp); NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; [[NSFileManager defaultManager] removeItemAtPath:lastPath error:nil]; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); documentsDirectory = [paths objectAtIndex:0]; directoryContent = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil] retain]; //tableview handling below }

  • Modal View Does Not Appear in Center in Horizontal Orientation

    - by Sheehan Alam
    I have a UIPresentationFormSheet (contains a textview) that appears in the center of the screen when I am in vertical orientation. When I dismiss the modal view, it disappears fine. When I am in horizontal orientation my modal view does not appear in the center of the screen. I have to dismiss my keyboard for the modal view to appear in the center. [self presentModalViewController:composeTweetController animated:TRUE]; When I dismiss the modal view in horizontal orientation the app automatically switches to vertical orientation. -(void)dismissComposeTweetView{ [self dismissModalViewControllerAnimated:TRUE]; } I want the following to happen: Modal view should appear in the center in horizontal orientation Modal view should disappear without switching to vertical orientation

  • Change the contents of a UITableView via a swipe?

    - by Mark
    Im currently using a UITableView like any other, and I am researching into the ability to perform a swipe gesture on the screen, which will then shift the contents of the visible table over to display new content for example: swiping right-to-left on the screen would change (via animation) the contents within each of the cells on screen to show new data. What I can do is detect a swipe on the cells, or perhaps on the UITableViewController, but what I dont know how to do two fold: 1) Change data in all cells (could you have a set of hidden views within a custom table cell that animate in and out of each cell per swipe?) 2) How can you do this to all cells? Thanks a lot Mark

  • Clicking the mouse down to drag objects on Mac

    - by Uri
    I've been using the following code to issue clicks programmatically on a Mac void PostMouseEvent(CGMouseButton button, CGEventType type, const CGPoint point) { CGEventRef theEvent = CGEventCreateMouseEvent(NULL, type, point, button); CGEventSetType(theEvent, type); CGEventPost(kCGHIDEventTap, theEvent); CFRelease(theEvent); } void Click(const CGPoint point) { PostMouseEvent(kCGMouseButtonLeft, kCGEventMouseMoved, point); NSLog(@"Click!"); PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseDown, point); PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseUp, point); } Now, I'm trying to click down to be able to drag objects, like a scroll bar or an application's window. I'm using the following: PostMouseEvent(kCGMouseButtonLeft, kCGEventMouseMoved, point); NSLog(@"Click Down!"); PostMouseEvent(kCGMouseButtonLeft, kCGEventLeftMouseDown, point); When i ran the code above something interesting will happen, when the left mouse down is issue nothing seem to happen, I move my mouse and the window doesn't move, however when I added a mouse up event then the window jumped to the location where I supposedly dragged it. this is sort of OK, however, how do I can make the mouse click down and drag an object? Note: I do have a whole method to see when the mouse stopped moving so I can click up. please post code. Thanks

  • How to find the only UILabel in a view and hide it?

    - by tarnfeld
    I am adding a UILabel as a subview to a UIView and sometime later I want to hide it. It is assigned to a variable but I don't think setting the variables property Hidden after it's been added to the view will work (well it doesn't seem to anyway). Is there a way to loop through the subviews in a view and then find the one that has a specific tag or is of type UILabel that I could then remove?

  • iPhone - Change entity class (NSManagedObject) to make them initializable

    - by ncohen
    Hi everyone, I would like to use my custom NSManagedObject like a normal object (as well as its regular functions). Is it possible to modify the class in order to be able to initialize it like a normal object? [[myManagedObject alloc] init]; Thanks edit: to clarify the question, will it screw everything up if I change the @dynamic with @synthesize in the implementation?

  • drawRect gets called on UIView subclass but not on UIViewController

    - by HotFudgeSunday
    My code is working so far but I had to create a Class for the UIView. This is a bit inconvenient because I need to interact with the ViewController too. BTW, I did try [self setNeedsDisplay] on the ViewDidLoad of the UIViewController subclass file but it didn't work. Here's the code, which works on UIView Subclass but doesn't get called on a UIViewController one: - (void)drawRect:(CGRect)rect { UIColor *currentColor = [UIColor redColor]; CGContextRef context = UIGraphicsGetCurrentContext(); someNum = 1; CGContextBeginPath(context); CGContextMoveToPoint(context, 30, 40); [self addDotImageX:30 andY:40]; CGContextSetLineWidth(context, 2); CGContextSetStrokeColorWithColor(context, currentColor.CGColor); CGContextStrokePath(context); } Any ideas on what to try? BTW, this is a TabBar App. I know those can somehow block the calls to drawRect. The Tabs where created programatically, not through a Nib. Eg: NSMutableArray *listOfViewControllers = [[NSMutableArray alloc] init]; UIViewController *vc; vc = [[Education alloc] init]; vc.title = @"Education"; [listOfViewControllers addObject:vc]; vc.tabBarItem.image = [UIImage imageNamed:@"info.png"]; [vc release]; I would appreciate any ideas. I've been through the answers on this site related to setNeedsDisplay not calling drawRect and haven't found an answer for my particular case. Thanks.
