• Decimal point issue on cocoa app

  - by Manuel Rocha

  I there, I'm trying making my first cocoa app, but I'm having problems with float numbers because of the regional settings. If I write on the TextBox the float number 1.2 I only can get the number 1, but If I write on the same TextBox the same float number but this time with the ',' sign instead (1,2) I can get the right float value. How can I bypass the regional settings? Kind Regards, Manuel Rocha

• UITableViewCellSeparatorStyleNone does not hide blue separator line when selecting in UITableView

  - by clozach

  Before describing the problem, let me first point out that this is a distinct issue from this question. The Problem This screenshot was taken with a break set at tableView:didSelectRowAtIndexPath:, and as you can see in the simulator (far right of the image), there's a single-pixel blue line at the bottom of the selected cell. This is not the design asked for by the client, nor is it how this app used to behave: there should be no separator, even on selection. How I Got Here I'd initially designed this table view using custom UITableViewCell classes with corresponding nib (.xib) files and had no trouble with selections: the separator was hidden as desired. Predictably, scrolling was sluggish due to all the overhead from the view hierarchy, so I reworked the custom cells to use Loren Brichter's fast scrolling solution. Now scrolling is much faster, but I can't get rid of the separator for the life of me. What I've tried At the time of the screenshot above... the table view has "Separator [None]" in IB. the UIViewController that contains the table view has this line in viewDid Load: self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone; As you can see in the screenshot, I inserted some unused lines to prove that separatorStyle is set as desired. Other testing confirms that tableView and self.tableView are equivalent pointers at that same breakpoint. I've also tried setting tableView.separatorColor to black and to clear, all with the same result: the cells look right until a selection is made.

• How to convert an NSArray of NSManagedObjects to NSData

  - by carok

  Hi, I'm new to Objective C and was wondering if anyone can help me. I am using core data with a sqlite database to hold simple profile objects which have a name and a score attribute (both of which are of type NSString). What I want to do is fetch the profiles and store them in an NSData object, please see my code below: NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"GamerProfile" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Name" ascending:YES]; NSArray *sortDecriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDecriptors]; [sortDescriptor release]; [sortDecriptors release]; NSError *error; NSArray *items = [self.managedObjectContext executeFetchRequest:fetchRequest error:&error]; NSData *data = [NSKeyedArchiver archivedDataWithRootObject:items]; [self SendData:data]; [fetchRequest release]; When I run the code I'm getting the error "Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '* -[GamerProfile encodeWithCoder:]: unrecognized selector sent to instance 0x3f4b530'" I presume I have to add an encodeWithCoderClass to my core data NSManagedObject object (GamerProfile) but I'm not sure how to do this even after reading the documentation, My attempt at doing this is below. I'm not sure if I'm going along the right lines with this as get a warning stating "NSManagedObject" may not respond to '-encodeWithCoder'" I would really, really appreciate it if someone could point me in the right direction!! Thanks C Here is the code for my GamerProfile (CoreData NSManagedObject Object) with my attempt at adding an encodeWithCoder method... Header File #import <CoreData/CoreData.h> @interface GamerProfile : NSManagedObject <NSCoding> { } @property (nonatomic, retain) NSString * GamerScore; @property (nonatomic, retain) NSString * Name; - (void)encodeWithCoder:(NSCoder *)coder; @end Code File #import "GamerProfile.h" @implementation GamerProfile @dynamic GamerScore; @dynamic Name; - (void)encodeWithCoder:(NSCoder *)coder { [super encodeWithCoder:coder]; [coder encodeObject:GamerScore forKey:@"GamerScore"]; [coder encodeObject:Name forKey:@"Name"]; }

• Creating a "chat bubble" on the iPhone, like Tweetie.

  - by Coocoo4Cocoa

  Just curious, did I overlook somewhere in the API to display a chat bubble type image as found in the iPhone's SMS application? There's a few applications out there that use bubbles that look verbatim to the iPhone's and I'm wondering if they're using a native widget or their own image. This is also seen in the Tweetie application where the content of the tweets are.

• UIScrollView setZoomScale not working ?

  - by iFloh

  Hi, I am struggeling with my UIScrollview to get it to zoom-in the underlying UIImageView. In my view controller I set - (UIView *)viewForZoomingInScrollView:(UIScrollView *)scrollView { return myImageView; } In the viewDidLoad method I try to set the zoomScale to 2 as follows (note the UIImageView and Image is set in Interface Builder): - (void)viewDidLoad { [super viewDidLoad]; myScrollView.contentSize = CGSizeMake(myImageView.frame.size.width, myImageView.frame.size.height); myScrollView.contentOffset = CGPointMake(941.0, 990.0); myScrollView.minimumZoomScale = 0.1; myScrollView.maximumZoomScale = 10.0; myScrollView.zoomScale = 0.7; myScrollView.clipsToBounds = YES; myScrollView.delegate = self; NSLog(@"zoomScale: %.1f, minZoolScale: %.3f", myScrollView.zoomScale, myScrollView.minimumZoomScale); } I tried a few variations of this, but the NSLog always shows a zoomScale of 1.0. Any ideas where I screw this one up?

• Select row After UIPickerView is loaded

  - by Steve Gibson

  I have an iphone database app that loads a UIPickerView with data from a table. I want to set the selected row to a particular row from the data in another table. for example: Lets say I have a UIPickerView that is loaded with X number of names of the iPhone users friends (the number of names is variable, could be 1 or 1000 and all are entered into the DB by the user). The iPhone user has a preference set that their current best friend is TED. I want the UIPickerView to be position to TED when displayed. Where do I call selectRow? I tried in viewDidAppear but it was never called, in titleForRow which caused all kinds of strange behavior. viewDidLoad and viewWillAppear are out of the question because I don't know what's in the datasource to the picker yet. Thanks in advance.

• How to get fast, smooth scrolling with UIWebView?

  - by sam

  UIWebView exhibits jerky behavior when scrolling fast through lots of content. Mobile Safari, on the other hand, scrolls quickly and smoothly. It displays a simple checkerboard pattern while scrolling and then renders the page when scrolling is done. How can we get Mobile Safari's fast, smooth scrolling behavior with a UIWebView?

• Why does navigationItem.titleView align left when presentmodalviewcontroller called?

  - by jm333

  I'm using a UILabel for the titleView of a navigation bar (I'm making simple in-app web browser). It works fine, except that when I present a modal view controller, the titleView shifts from the center of the navbar to the far left (underneath the back button). I've tested in 3.0 and up. Here is relevant code: - (void)viewDidLoad { [super viewDidLoad]; // Title view label CGRect labelFrame = CGRectMake(0.0, 0.0, 120.0, 36.0); UILabel *label = [[[UILabel alloc] initWithFrame:labelFrame] autorelease]; label.font = [UIFont boldSystemFontOfSize:14]; label.numberOfLines = 2; label.backgroundColor = [UIColor clearColor]; label.textAlignment = UITextAlignmentCenter; label.textColor = [UIColor whiteColor]; label.shadowColor = [UIColor blackColor]; label.shadowOffset = CGSizeMake(0.0, -1.0); label.lineBreakMode = UILineBreakModeMiddleTruncation; self.navigationItem.titleView = label; } -(void)displayComposerSheet:(NSString*)mailto { MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; [self presentModalViewController:picker animated:YES]; [picker release]; } Screenshots: http://img689.imageshack.us/img689/7968/titleviewshift.jpg Any idea why this is happening? Thanks.

• Application with two UITabBarControls

  - by kovpas

  Hello, I want to create an app, whith the following structure: UITabBarController ..UINavigationController ....UITabBarController So, in other words, I want to load first UITabbarController as my main ViewController, that appears on application start, in its' first tab there's a UINavigationController with a table, which shows another UITabBarController by pressing on a table cell. I started Tab Based application, set first tab to UINavigationController, and its ViewController to my TableViewController. I also created second UITabBarController in Interface Builder. Created a separate class for this controller. Everything works fine at start - my first UITabBarController is shown perfectly, but when I'm trying to push my second UITabBarController, using my UINavigationController, it looks like nothing is loaded from a .xib file - there are just an empty TabBar and NavigationBar pushed. Seems, that something is wrong with an architecture, but I can't figure out the problem. Thanks in advance and I'm sorry for my poor English. Please let me know if something is not clear, I'll try to rephrase it :).

• Integrate Google Maps API into an iPhone app

  - by Corey Floyd

  Update: iPhone SDk 3.0 now addresses the question here, however the NDA prevents any in depth discussion. Log in to the iPhone Dev Center if you need more info. Ok, I have to admit I'm a little lost here. I am fairly comfortable with Cocoa, but am having trouble picking up the bit of javascript needed to solve this problem. I am trying to send a request to Google for a reverse geo code. I have looked over the Google documentation I have viewed here: http://code.google.com/apis/maps/documentation/index.html http://code.google.com/apis/maps/documentation/geocoding/ Even after a rough reading, I am missing a basic concept: How do I talk to google? In some examples, they show a url being sent to google (which seems easy enough), but in others they show javascript. It seems for reverse geocoding, the request might be be harder than sending the url with some parameters (but I hope I am wrong). Can someone point me to the correct way to make a request? (In objective-C, so I can wrap my head around it)

• UINavigationController does not set view properties correctly when pushed

  - by Sheehan Alam

  I have a UITabBarControllerDelegate that pushes a new view controller when a certain tab is pressed: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { MyView* myView = [[[MyView alloc] initWithNibName:@"MyView" bundle:nil]autorelease]; if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; [self.navigationController myView animated:YES]; } } However, if I change my code to set the tabbar's selected view controller to myView everything works, but I don't get my navigation bar: if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; self.tabBarController.selectedViewController = myView; } How can I set the reloadFriends property in MyView and have the navigation bar at the top?

• Decode received multipart/form-data request in Cocoa

  Hi: I wonder if there is any possibility to explicitly decode an incoming multipart/form-data POST request. Is there any lib to handle this safely?

• UIToolbar above UIWebView inside UIScrollView

  - by Nick VanderPyle

  I'd like to display a toolbar above a UIWebView but hide the toolbar until the person "pulls it down". The same functionality can be seen in Safari on the iPhone. When the page loads, the toolbar containing the address is hidden. You must pull it down. In Safari it's possible to scroll up and eventually see the toolbar or scroll down through the page contents. I've tried placing a UIToolbar and UIWebView inside a UIScrollView but it didn't work. I've tried setting the UIScrollView to the size of the toolbar and webview combined, but that didn't work. - (void)viewDidLoad{ CGSize size = CGSizeMake(webView.frame.size.width, toolBar.frame.size.height + webView.frame.size.height); [scrollView setContentSize:size]; } How should I go about doing this?

Is it possible to change the fontcolor for a specific component according the presence of data in the DB ? For example the field in the DB is null the component font color should be RED otherwise black. Any help will be appreciated ! Dario ================== Thanks Kenny, I have to apply to a single UIPicker only. So I', returning the view parametere (without modificatiosn). The result is all the pickers show empty rows. Thanks for help ! Here you will find the code fragment: - (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view { if (pickerView == tipoPk){ UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100,30)]; label.textColor = [UIColor redColor]; switch (component) { case PK_Tipo: label.text = [tipoArray objectAtIndex:row]]; break; case PK_Settore: label.text = [settoreArray objectAtIndex:row]]; break; default: break; } return label; } else { return view; // <==== return view for non related pickerviews , but no rows shown } }

• Changing UIImageView animation speed

  - by Nikolas Stephan

  I am using the UIImageView to animate a bunch of images. I know that I can change the speed by altering animationDuration, but that doesn't seem to take effect until the animation is restarted. My problem is that beside not really wanting to have to restart the animation as this limits me to only being able to change the speed once per cycle, there also doesn't seem to be a way to find out what frame is currently being shown and I would therefore have to rely on a timer to "guess" which one it is. So my question is whether there is a way to change the speed without restarting the animation and if not is there some way I could avoid the aforementioned problem? I'm not too keen to write my own animation class, but may end up having to if there isn't a nicer solution.

• iPhone SDK: Transparent tableviewcell isn't transparent?

  - by Harkonian

  I have a UITableViewController that has a background image. I am setting the image for the tableview like this: [self.view setBackgroundColor: [UIColor colorWithPatternImage: [UIImage imageWithContentsOfFile: [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent: @"background1.jpg"]]]]; The problem is, each of my custom tableview cells get the same background image--it's repeated in each cell. As a test, I tried making everything in my cell transparent with an alpha of 0.0, but even then although I can't see any of the labels in each cell, I still see the background image repeated in each cell: cell.backgroundColor = [UIColor clearColor]; cell.contentView.backgroundColor = [UIColor clearColor]; cell.contentView.alpha = 0.0; cell.alpha = 0.0; Any suggestions on how to get my table's background image to stop repeating in each cell would be appreciated!

• iPhone UISlider with two thumbs/indicators?

  Is anyone aware of a version of the iPhone UISlider control with two thumbs? I need a control that will allow specifying a range of values. The UISlider API docs would imply this isn't possible with the standard control, so I was wondering if anyone had a solution for this (or had solved it themselves).
