  • How do I pass a string or data object between two view controllers?

    - by Jonathan
    In my last question i asked how to best send a string from one view controller to another, both which were on a navigation stack: http://stackoverflow.com/questions/2898860/pass-string-from-tableviewcontroller-to-viewcontroller-in-navigation-stack However I just realised I can either pass the path to the file in the app's document's folder as the first (the table view) has already accessed the data in the file should I pass viewcontroller the data to the pushed VC?

  • Force a view change from a button when using UITabBarController

    - by user342197
    Hello - When using a UITabBarController, when the user enters some data on View1 and presses a button, I need to perform some calculations and present the results on View2. I have an AppDelegate, View1Controller, View2Controller, and View3Controller (View3 is a basically static view). My AppDelgate declares UITabBarController *rootController; On View1, I have the calculations being performed in an IBAction for buttonPressed; however, I can't seem to force the view to switch to View2 programmatically. I have done a lot of searching for similar problems, and think I should be doing something like "self.rootController.selectedIndex = 1"; however,when I do this from within buttonPressed on my View1Controller, I get an error "request for member rootController in something not in a structure or union". I think I'm missing something basic here... probably need do do something with my AppDelegate, but I'm banging my head against the wall. Can anyone provide some guidance in this situation...like key things I should do in View1Controller header and implementation with reference to my AppDelgate? Thank you!

  • apple push notification review

    - by user280390
    Hey all, I am implementing APN's and want to release without switching it on yet.. So the app will happily receive them. but we will choose not to send them until later. My question is, as when we want to send notifications is in our control, do apple care about this when reviewing the app. I thinking not, maybe they send a test notification to the device to prove it works? but if anyone has any experience in dealing with this any info would be much appreciated. Thanks.

    - by Lee Armstrong
    I have some NSString varibales that incude items like Ð and Õ and if I do cell.textLabel.text = person.name; and if it contains one of those characters the cell.textlabel is blank! I have discovered that if I use NSString *col1 = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)]; To pull my data back it pulls back null, however using the deprectared method NSString *col1 = [NSString stringWithCString:(char *)sqlite3_column_text(compiledStatement, 0)]; Shows the characters! Any ideas?

  • NSString writeToFile operation couldn't be completed

    - by Chonch
    Hey, I have an xml file in my application bundle. I want to copy it to the documents folder at installation and then, every time the app launches, get the newest version of this file from the Internet. I use this code: // Check if the file exists in the documents folder NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; if (![[NSFileManager defaultManager] fileExistsAtPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"]]) // If not, copy it there (from the bundle) [[NSFileManager defaultManager] copyItemAtPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"OriginalFile.xml"] toPath:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] error:nil]; // Get the newest version of the file from the server NSURL *url=[[NSURL alloc] initWithString:@"http://www.sitename.com/webservice.asmx/webserviceName"]; NSString *results = [[NSString alloc] initWithContentsOfURL:url]; // Replace the current version with the newest one, only if it is valid if (results != nil) [results writeToFile:[documentsPath stringByAppendingPathComponent:@"fileName.xml"] atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil]; The problem is that the writeToFile command always returns NO and the file's contents remain identical to the original file I included in my app bundle. I checked the value of results and it's correct. I also made sure that the app does perform the writeToString command, but still, it always returns NO. Can anybody tell me what I'm doing wrong? Thanks,

  • NAN mixing float and GLFloat?

    - by carrots
    This often returns NAN ("Not A Number") depending on input: #define PI 3.1415f GLfloat sineEaseIn(GLfloat ratio) { return 1.0f-cosf(ratio * (PI / 2.0f)); } I tried making PI a few digits smaller to see if that would help. No dice. Then I thought it might be a datatype mismatch, but float and glfloat seem to be equivalent: gl.h typedef float GLfloat; math.h extern float cosf( float ); Is this a casting issue?

  • remove Annotation removes random amount of annotations at a time

    - by skinny123
    I've got this code to erase an annotations (pins) in my mkmapview without erasing my blue dot (userLocation). The problem is that it erasing the pins I've added in seemingly random numbers. when it's called through an IBAction it removes the first 5 then click again it removes the next 3, then the next 2, then the last one. When pressed I need it to remove that latest pin...etc. etc. for (int i = 0; i < [mapView.annotations count]; i++ ) { if ([[mapView.annotations objectAtIndex:i] isKindOfClass:[MyAnnotation class]]) { [mapView removeAnnotation:[mapView.annotations objectAtIndex:i]]; } }

  • How to assign optional attribute of NSManagedObject in a NSManagedObjectModel having Three NSManaged

    - by Kundan
    I am using coredata framework. In my NSManagedObjectModel i am using three entities that are Class, Student and Score where class and student have one-to-many & inverse relationship and Student and Score have also inverse but one-one relationship. Score entity has all optional attributes and having default '0' decimalVaue, which is not assigned at the time new Student is added. But later i want to assign them score individually and also to particular attribute not all of score attributes in a go. I am able to create and add Students to particular Class but dont have any idea how to call particular student and assign them score. For example I want to assign Score'attribute "dribbling" [there are many attributes like "tackling"] a decimal value to Student "David" of Class "Soccer" ,how i can do that? Thanks in advance for any suggestion.

  • Popping multiple levels in UITableViewController

    - by LavaSlider
    I would like to be able to pop multiple views from a UITableViewController stack. For example in the Apple DrillDownSave example, when viewing Level 3 to go back to Level 1 or when viewing an Item to go back to Level 2 when a button is pushed. I tried: [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; [self.navigationController popViewControllerAnimated: NO]; and [self.navigationController popViewControllerAnimated: NO]; [self.navigationController.parentViewController.navigationController popViewControllerAnimated: NO]; but these leave me the same place as just a single popViewControllerAnimated:. Is there an easy way to do this?

  • Issue with UITextView in an animation block

    - by collin
    I'm having an issue with a UITextView inside another UIView whose frame is manipulated in an animation block when the keyboard displays. During the animation block the UIView scales beautifully and as expected, but the UITextView jumps out of it's superview(the UIView being animated) at the start of the animation. By the end of the animation, the UITextView ends up in the right place... what gives? Can anybody explain why the UITextView is jumping out of it's container view at the start of the animation? Thanks in advance.

  • Client-side framework for web-app with good audio support

    - by Poita_
    I'm trying to create a client-side web app that generates music procedurally using some user-input parameters, so I'm looking for a framework (e.g. Flash, Silverlight etc.) that has the capability to play audio at a specified pitch. Whether it is playing a WAV/MP3 file, using MIDI output, or just playing beeps doesn't really matter -- I just need something that will enable me to generate arbitrary music client-side. I've done a bit of searching and it appears that Flash might have the ability to change pitch with the help of a third-part plugin, but I couldn't find anything similar for Silverlight. I can go a try all them out manually if need be, but I thought I'd ask here first just in case anyone had tried something like this before. Thanks in advance

  • Does the type in this KVC validation method matter?

    - by dontWatchMyProfile
    For example, in the docs a KVC-style validation method is implemented like this: -(BOOL)validateAge:(id *)ioValue error:(NSError **)outError They used id* as the type for ioValue. Since that's not part of the method signature, I wonder if it would hurt to do something like: -(BOOL)validateAge:(NSNumber *)ioValue error:(NSError **)outError Is this still fine with KVC?

  • Custom UITableViewCell not appearing when row height is set

    - by Sheehan Alam
    I have a custom UITableViewCell which I have created in IB. My labels display when I don't over-ride: - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath however my content is squished. I want the height to be 120px so I have the following: - (CGFloat)tableView:(UITableView *)tblView heightForRowAtIndexPath:(NSIndexPath *)indexPath { CGFloat rowHeight = 120; return rowHeight; } I'm not sure why the content inside of my UITableViewCell all of a sudden disappears?

  • Xcode 4: deleting items in Build Settings

    - by occulus
    In XCode 4.0 there's a newly designed Build Settings page. My problem is that I can't see how to remove a setting once I've specified it. Example: I've changed "Versioning System" to "Apple Generic" at the target level. Afterwards I realised I should set it at the project level, and so I want to delete the target level setting. However, there's no way I can see to remove the setting -- you click on it and there's two options, neither of which is the default "not specified" empty setting. Hitting the delete key on the keyboard nothing. The same goes for fields that accept text -- if I try to delete a setting by just deleting all the text set, it still shows that field in green, but with no text in it, and regards it as the presence of a setting.

  • How to reset all the values after completion of the game, before starting it again ?

    - by srikanth rongali
    I have writing a small shooting game in cocos2d. Winning the game is to eliminate all the 10 enemies. After that end screen comes showing 'You Won' and 'Play Again'. If I go for 'Play Again' option the game is starting from where I need. But, the problem is that the game is continuing from previously ended state. I mean it is not starting from enemy 1 again instead it is just showing the end of 10 enemy. I think I have to reset all the values before pushing the scene. But should I reset all the values I have used or there is any other way ? Thank You.

  • Create a bubble effect on a grid OpenGL-ES

    - by Charles Michael
    Hi there. I have created a grid with 40 x 40 vertex3D (small but useful) I can pick a single vertex out of that grid by simply calling a function with the position array[X][Y], And therefore neighbors too. How can I raise up neighbor vertex Z value so they kinda look like a bubble or sphere kind of thingy? My first tough was to use: Neighbor_vertex.Z = sin(PI/4 * 1 - ( 1/ distance_between_Neighbor_and_Pivot) ) * desired_Max_Height But all I got is something like a wave.... and I would like to have a bubble or Sphere like shape. THX dudes and dudettes

  • How can I a sprite image from a set of sprites which have different properties for each sprite?

    - by srikanth rongali
    In my application one player and 10 targets are there. Each target appears one after the other (from target1 to target10). It's a shooting game. If we hit the first target then second target will come. The targets have properties like name, speedOfGunDraw, probability to hit the player, speedOfFire. What should I do to make them appear one after the other with these properties. I am using CCMenuItem for the target. I am using a sprite for the player. Please give me idea to do this. Thank You.

    Hey guys, I have a asynchronous url request within a for loop. This loop is called 20 times, each time one parameter of the webaddress is changed. Everytime the didFinishLoading method is called I want to hand over the data of this specific webadress. The problem now is that when I run the for loop, the didFinishLoading method is not called, only at the end. Any suggenstions on how to make the loop wait for complete loading the data for the specific URL? Thanks a lot.
