  • Accessing ViewController's variables from UIActionSheet delegate

    - by VansFannel
    Hello. I have the following code: @implementation SendMapViewController NSMutableArray *emails; At this method I create emails array and I add some NSStrings: - (BOOL) peoplePickerNavigationController: (ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson: (ABRecordRef)person { ABMultiValueRef emailInfo = ABRecordCopyValue(person, kABPersonEmailProperty); NSUInteger emailCount = ABMultiValueGetCount(emailInfo); if (emailCount > 1) { UIActionSheet *emailsAlert = [[UIActionSheet alloc] initWithTitle:@"Select an email" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:nil]; emails = [NSMutableArray arrayWithCapacity: emailCount]; for (NSUInteger i = 0; i < emailCount; i++) { NSString *emailFromContact = (NSString *)ABMultiValueCopyValueAtIndex(emailInfo, i); [emails addObject: emailFromContact]; [emailsAlert addButtonWithTitle:emailFromContact]; [emailFromContact release]; } [emailsAlert addButtonWithTitle:@"Cancel"]; [emailsAlert showInView:self.view]; [emailsAlert release]; } else { ... } CFRelease(emailInfo); [self dismissModalViewControllerAnimated:YES]; return NO; } As you can see in code, if there are more than one email I show and UIActionSheet. When user clicks on a button representing and email, I want to execute the following code: - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if ([emails count] >= buttonIndex) { NSString *contactEmail = (NSString *)[emails objectAtIndex:buttonIndex]; ... } } But emails array hasn't got any email. What I'm doing wrong? I'm developing for iPhone.

  • How to avoid keyboard hide & show when focus changes from UITextField and UIWebView?

    - by Manoj
    I have a requirement in which the view contains one native UITextField and one UIWebView. The issue is if I switch the focus from UITextView to UIWebView, the keyboard window flicker(hides and then shows). ie, I got UIKeyboardWillHideNotification and UIKeyboardDidShowNotification But, this is not happening when I switch the other way. ies, I got only UIKeyboardDidShowNotification Is there any way to avoid this flickering effect? Note: I also notices if I have multiple UITextField and UIWebView, this issue is not happening with the same type of views.

  • Why is the compiler caching my "random" and NULLED variables?

    - by alex gray
    I am confounded by the fact that even using different programs (on the same machine) to run /compile, and after nilling the vaues (before and after) the function.. that NO MATTER WHAT.. I'll keep getting the SAME "random" numbers… each and every time I run it. I swear this is NOT how it's supposed to work.. I'm going to illustrate as simply as is possible… #import <Foundation/Foundation.h> int main(int argc, char *argv[]) { int rPrimitive = 0; rPrimitive = 1 + rand() % 50; NSNumber *rObject = nil; rObject = [NSNumber numberWithInt:rand() % 10]; NSLog(@"%i %@", rPrimitive, rObject); rPrimitive = 0; rObject = nil; NSLog(@"%i %@", rPrimitive, rObject); return 0; } Run it in TextMate: i686-apple-darwin11-llvm-gcc-4.2 8 9 0 (null) Run it in CodeRunner: i686-apple-darwin11-llvm-gcc-4.2 8 9 0 (null) Run it a million times, if you'd like. You can gues what it will always be. Why does this happen? Why oh why is this "how it is"?

  • Dump UIImage on iPhone

    - by Leon
    I wonder how to save the UIImage object from UIImagePickerController into the App Document directory. I tried to use UIImageJPEGRepresentation() method and UIImagePNGRepresentation(), but it seemed the image data was changed.

  • Calculating driving distance in iPhone

    - by Prasanna
    Hi, I need to find the driving distance between 2 locations. I do not need to display the directions in a map, just need to calculate the distance, which I need to use in my application. Does MapKit allow this? Is there an alternative that can be used? I am able to get forward geo-coding using CloudMade, but there doesn't seem to be an option to obtain driving distance. Appreciate any help.

  • iPhone: Error when using -(id)initWithNibName

    - by Nic Hubbard
    I am trying to use the following code, but I always get an error that I can find little information about: - (id)initWithNibName:@"MyRidesListView" bundle:nil { if ((self = [super initWithNibName:@"MyRidesListView" bundle:nil])) { // Custom initialization } return self; } Error: expected identifier before 'OBJC_STRING' token This seems like a simple method to be calling. This is for a UINavigationController. Ideas?

  • Test iPhone in-app purchases on a different bundle?

    - by Andrew Johnson
    We have a group of beta testers for iPhone app. Recently, we added in-app purchases to the app. Before this, we would send out ad hoc builds to beta testers using a separate bundle ID and name so that they could have the store build and the ad hoc build on their phones. However, it seems like we have to build the ad hoc copy with the same Bundle ID to test in-app purchases, and this means we can't send out a seperate beta copy - our beta file (annoyingly) overwrites the user's store-bought app. Is there any way to test in-app purchases in a different bundle ID? Do I need to set up fake, test in-app purchases for the test build too?

  • converting NSTimer running not on main runloop to GCD

    - by Justin Galzic
    I have a task that runs periodically and it was originally designed to run on a separate run loop than the main runloop using NSThread and NSTimer. What's the best way to adapt this to take advantage of GCD? Current code: -(void)initiateSomeTask { [NSThread detachNewThreadSelector:@selector(startTimerTask) toTarget:self withObject:nil]; } -(void)startTimerTask { // We won't get back the main runloop since we're on a new thread NSRunLoop *myRunLoop = [NSRunLoop currentRunLoop]; NSPort *myPort = [NSMachPort port]; [myRunLoop addPort:myPort forMode:NSDefaultRunLoopMode]; NSTimer *myTimer = [NSTimer timerWithTimeInterval:10 /* seconds */ target:self selector:@selector(doMyTaskMethod) userInfo:nil repeats:YES]; [myRunLoop addTimer:myTimer forMode:NSRunLoopCommonModes]; [myRunLoop run]; } Is there anything I can do besides replace detachNewThreadSelector with dispatch_async?

  • Graphical glitches when adding cells and scrolling with UITableView

    - by Daniel I-S
    I am using a UITableView to display the results of a series of calculations. When the user hits 'calculate', I wish to add the latest result to the screen. This is done by adding a new cell to a 'results' section. The UITableViewCell object is added to an array, and then I use the following code to add this new row to what is displayed on the screen: [thisView beginUpdates]; [thisView insertRowsAtIndexPaths:[NSArray arrayWithObject:newIndexPath] withRowAnimation: UITableViewRowAnimationFade]; [thisView endUpdates]; This results in the new cell being displayed. However, I then want to immediately scroll the screen down so that the new cell is the lowermost cell on-screen. I use the following code: [thisView scrollToRowAtIndexPath:newIndexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES]; This almost works great. However, the first time a cell is added and scrolled to, it appears onscreen only briefly before vanishing. The view scrolls down to the correct place, but the cell is not there. Scrolling the view by hand until this invisible new cell's position is offscreen, then back again, causes the cell to appear - after which it behaves normally. This only happens the first time a cell is added; subsequent cells don't have this problem. It also happens regardless of the combination of scrollToRowAtIndexPath and insertRowsAtIndexPath animation settings. There is also a problem where, if new cells are added repeatedly and quickly, the new cells stop 'connecting up'. The lowermost cell in a group is supposed to have rounded corners, and when a new cell is added these turn into square corners so that there is a clean join with the next cell in the group. In this case, however, a cell often does not lose its rounded edges despite not being the last cell anymore. This also gets corrected once the affected area moves offscreen and back. This method of adding and scrolling would be perfect for my application if it weren't for these weird glitches. Any ideas as to what I may be doing wrong?

  • UIButton custom font vertical alignment

    - by Willshaw Media
    I've got a UIButton which uses a custom font, which is set when my view loads: - (void)viewDidLoad { [super viewDidLoad]; self.searchButton.titleLabel.font = [UIFont fontWithName: @"FONTNAME" size: 15.0 ]; } The problem I've got is that the font is appearing to float up of the center line. If I comment out this line, the default font appears vertically centered fine. But changing to the custom font breaks the vertical alignment. I'm getting the same issue on a Table Cell with a custom font too. Do I need to tell the view somewhere that the custom font is not as tall as other fonts? EDIT: I've just realized that the font I'm using is a Windows TrueType Font. I can use it fine in TextEdit on the Mac, only a problem with the alignment in my App

  • Synthesized property of a protocol not seeing superclass' ivar

    - by hyn
    I have a situation where my subclass is not seeing the superclass' instance variable x. The ivar is obviously @protected by default, so why do I get a compiler error "x undeclared"? - (CGSize)hitSize { // Compiler error return size; } EDIT: hitSize is a property of a protocol my subclass is conforming to. The problem was that I had hitSize @synthesized, which was the culprit. The question then is why can't the synthesized getter see the ivar?

  • Dragging Files on the Dock Icon

    - by enchilada
    I know how handle dragging of files on the dock icon, and it has been asked before. However, I'm wondering, can I somehow get more control? For example, can I make the dock icon reject files that are not in the user's folder and allow only files that are in the user's folder? I'd rather do that instead of the app appearing as if it handles files outside the user's folder, and then within the app delegate afterwards reject the files by detecting the file paths. That doesn't seem good from a user's perspective.

  • Controls in UIActionSheet are positioning wrong

    - by Dave
    I need to display a pop with a UISwitch and a Done button when user taps on a button and save the state of the switch when the done button in the pop up is tapped. So I use UIActionSheet to do this - sheet = [[UIActionSheet alloc] initWithTitle:@"Switch Setting" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Done", nil]; theSwitch = [[UISwitch alloc] init]; [sheet addSubview:theSwitch]; [sheet showInView:self.view]; - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { if (buttonIndex == actionSheet.firstOtherButtonIndex) { theSwitch .on? NSLog(@"Switch is on") : NSLog(@"Switch if off"); } } All this works great. I have problem with positioning. Unfortunately, I don't have a screen shot at the moment to post here. But the switch appears at the very top on the same line with the Action Sheet title and then below that is the Done button. Please someone help me how to position the switch below the Title and increase the Action Sheet size so it looks neat. I need this asap. Thanks.

  • Cocoa-Touch framework for speaking to a TCP socket?

    - by Coocoo4Cocoa
    I have a daemon running on a server that's latched onto a TCP/IP port. I'm looking to see if there's currently any support iPhone/Cocoa-touch frameworks that gives a nice OO wrapper for speaking to the daemon over an IP socket. I need to be able to interactively query the daemon with commands and retrieve back information. If there isn't any OO wrappers for such a task, what's the next best bet?

  • UITabBarController "More" tab issues

    - by codemonkey
    I've got a UITabBarController with 7 tabs. Each of the 7 tabs has its own UINavigationController and customizes its toolbar. When a view is loaded via the UITabBarController's "More" menu its custom toolbar isn't appearing. If i switch the order of the views around so that the same view is now accessible from the UITabBar without going through the "More" menu then the custom toolbar shows up like it's supposed to. Is there a way to customize a NavigationController's toolbar when that NavigationController is loaded via the "More" menu of a TabBarController? I'm actually also interested in replacing the "More" menu navigation controller with my own custom one on views loaded via the "More" menu... not sure whether that's even possible. Any feedback will be appreciated.
