• CorePlot linker errors after upgrading iOS SDK

  - by JustinXXVII

  This seems like it's happened before but somehow ended up working itself out. It's happened again and I can't seem to get this fixed. I use the CorePlot Cocoa Touch framework. Everything was fine until I upgraded to the new 4.3 beta. Now my project won't compile, and is giving me linker errors for unknown symbols having to do with CorePlot. I've become a pro at adding the framework to my project, and I've checked and rechecked the instructions trying to do it again. Is there a button I can click or anything to just make this work again? I've used these instructions to try to re-add the framework, to no avail EDIT: By the way, this compiles just fine for simulator and runs graphs no problem. Compiling for the device gives me the linker errors, as follows: "_OBJC_CLASS_$_CPPlotRange", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPXYGraph", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPTextStyle", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPLineStyle", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPScatterPlot", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPAxisLabel", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPPlotSymbol", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPColor", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPFill", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_CPDecimalFromFloat", referenced from: -[GraphStatsWindow setNewGraph] in GraphStatsWindow.o -[iPadGraphView viewDidLoad] in iPadGraphView.o -[GraphTrendView setNewGraph] in GraphTrendView.o "_kCPPlainWhiteTheme", referenced from: -[GraphStatsWindow setNewGraph] in GraphStatsWindow.o -[iPadGraphView viewDidLoad] in iPadGraphView.o -[GraphTrendView setNewGraph] in GraphTrendView.o "_OBJC_CLASS_$_CPTheme", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o ld: symbol(s) not found for architecture armv7

• Adding AllowPartiallyTrustedCallersAttribute To Paypal ASP.NET SDK

  - by snwr

  Currently, I cannot use Paypal Pro on my host (GoDaddy) because it requires Full trust level. After digging in Google, it seems a workaround is possible by adding AllowPartiallyTrustedCallersAttribute to the Paypal assembly. I have seen code samples that use AllowPartiallyTrustedCallersAttribute in their AssemblyInfo.cs file, however, I've yet to run into a code example that also happens to be using PayPal. My question is where should the AllowPartiallyTrustedCallersAttribute be added in my project if my objective is to make the PayPal assembly work? I have tried adding it to my AssemblyInfo.cs for the project that contains the entire website, but I have not been successful. At this point, any insight or shot in the dark would be greatly appreciated. Even if someone could point me in the general direction of some documentation I would be grateful. AllowPartiallyTrustedCallersAttribute Reference: http://msdn.microsoft.com/en-us/library/system.security.allowpartiallytrustedcallersattribute.aspx

• iPhone SDK: Orientation (Landscape and Portrait views)

  - by domness

  Okay, I've got my normal app which is in portrait mode. I can force my app to go to landscape mode for a view (using navigationcontroller and viewcontroller) like this: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeRight]; } But then when I go back to the main menu (tableview) it goes straight back to portrait. I try this code: - (void)viewWillAppear:(BOOL)animated { [[UIDevice currentDevice] setOrientation:UIInterfaceOrientationPortrait]; } But that doesn't work.. Any ideas?

• Problem in encoding and decoding the string in Iphone sdk

  - by monish

  HI Guys, Here I am having a problem In encoding/decoding the strings. Actually I had a string which I am encoding it using the base64.which was working fine. And now I need to decode the string that was encoded before and want to print it. I code I written as: I imported the base64.h and base64.m files into my application which contains the methods as: + (NSData *) dataWithBase64EncodedString:(NSString *) string; - (id) initWithBase64EncodedString:(NSString *) string; - (NSString *) base64EncodingWithLineLength:(unsigned int) lineLength; And the code in my view controller where I encode the String is: - (id)init { if (self = [super init]) { // Custom initialization userName = @"Sekhar"; password = @"Bethalam"; } return self; } -(void)reloadView { NSString *authStr = [NSString stringWithFormat:@"%@:%@",userName,password]; NSData *authData = [authStr dataUsingEncoding:NSASCIIStringEncoding]; NSString *authValue = [NSString stringWithFormat:@"%@", [authData base64EncodingWithLineLength:30]]; NSLog(authValue); //const char *str = authValue; //NSString *decStr = [StringEncryption DecryptString:authValue]; //NSLog(decStr); //NSData *decodeData = [NSData decode:authValue]; //NSString *decStr = [NSString stringWithFormat:@"%@",decodeData]; //NSStr //NSLog(decStr); } -(void)viewWillAppear:(BOOL)animated { [self reloadView]; } and now I want to decode the String that I encoded. But I dont know How to do that.can anyone suggest me with code how to get it. Anyone's help will be much appreciated. Thank you, Monish.

• Having trouble with event creation using the events.create API with the iPhone SDK

  - by MahatmaManic

  I'm using the FBConnect library in my iPhone app, and I'm trying to create Facebook events. After getting a valid session and verifying permissions, I'm using events.create and getting what looks like a valid event ID back from FB in a success response. Oddly the event isn't showing up on my account's Events page either in current or in past events. I thought the problem might be that the event might not include me as an attendee so I followed the successful events.create call with an events.rsvp call to set my status to "attending". That also gets back success from FB, but I'm still not seeing anything show up. Am I missing a step? Is there something other than Create and then RSVP that I need to do, or is there an error with the api/Facebook? I don't think I'm missing any of the required fields for event creation (name and start_time) and I am populating a lot of the other fields in event_info...

• Import csv data (SDK iphone)

  - by Ni

  I am new to cocoa. I have been working on these stuff for a few days. For the following code, i can read all the data in the string, and successfully get the data for plot. NSMutableArray *contentArray = [NSMutableArray array]; NSString *filePath = @"995,995,995,995,995,995,995,995,1000,997,995,994,992,993,992,989,988,987,990,993,989"; NSArray *myText = [filePath componentsSeparatedByString:@","]; NSInteger idx; for (idx = 0; idx < myText.count; idx++) { NSString *data =[myText objectAtIndex:idx]; NSLog(@"%@", data); id x = [NSNumber numberWithFloat:0+idx*0.002777778]; id y = [NSDecimalNumber decimalNumberWithString:data]; [contentArray addObject: [NSMutableDictionary dictionaryWithObjectsAndKeys:x, @"x", y, @"y", nil]]; } self.dataForPlot = contentArray; then, i try to load the data from csv file. the data in Data.csv file has the same value and the same format as 995,995,995,995,995,995,995,995,1000,997,995,994,992,993,992,989,988,987,990,993,989. I run the code, it is supposed to give the same graph output. however, it seems that the data is not loaded from csv file successfully. i can not figure out what's wrong with my code. NSMutableArray *contentArray = [NSMutableArray array]; NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"csv"]; NSString *Data = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil ]; if (Data) { NSArray *myText = [Data componentsSeparatedByString:@","]; NSInteger idx; for (idx = 0; idx < myText.count; idx++) { NSString *data =[myText objectAtIndex:idx]; NSLog(@"%@", data); id x = [NSNumber numberWithFloat:0+idx*0.002777778]; id y = [NSDecimalNumber decimalNumberWithString:data]; [contentArray addObject: [NSMutableDictionary dictionaryWithObjectsAndKeys:x, @"x", y, @"y",nil]]; } self.dataForPlot = contentArray; } The only difference is NSString *filePath = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"csv"]; NSString *Data = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil ]; if (data){ } did i do anything wrong here?? Thanks for your help!!!!

• iPhone SDK - CGBitmapContextCreate

  - by nax_

  Hi, I would like to create an image of my own. I already know its width (320*2 = 640) and height (427). So I have some raw data : unsigned char *rawImg = malloc(height * width * 4 *2 ); Then, I will fill it :) Then, I have to do something like that to get a bitmap and return a (UIImage *) : ctx = CGBitmapContextCreate(rawImg,width*2,height,8, ???, ???, kCGImageAlphaPremultipliedLast); UIImage * imgFinal = [UIImage imageWithCGImage:CGBitmapContextCreateImage(ctx)]; CGContextRelease(ctx); return imgFinal; But I don't know how to create my context ctx, as you can see with the "???", even tough I read the documentation... Please help ! Thanks :)

• Drawing individual pixels with iphone sdk.

  - by blob8108

  Hi, I've been trying to figure out how to make a powder toy style game on the iPhone. My problem is how to draw pixels to the screen. From what I've read, OpenGL is better for games as it is faster/hardware accelerated, but there is no method to draw pixels directly to the screen. Apparently drawing pixels to an off-screen frame buffer is the way to go, but how do I then pass this to OpenGL? Do I use a texture? (this is assuming I have no previous knowledge of iPhone graphics programming). Thanks!

• xstream and ibm j9 sdk incompatibilities on linux

  - by Yoni

  I encountered an incompatibility with xstream and IBM J9 jdk (the 32bits version). Everything worked fine when I used sun jdk but fails on IBM jdk (on linux only. on windows it's ok with both jdks). When debugging, the error appears to be that xstream uses a java.util.TreeSet internally but the set's iterator returns elements in the wrong order (I know this sounds very strange, but this is the behavior that I saw). Googling for related bugs didn't give any meaningful results I tried upgrading pretty much any component possible but no luck. I tried the following configurations: ibm jdk 1.6 SR 7 (bundled with WebSphere 7.0.0.9), xstream 1.2.2 ibm jdk 1.6 SR 8, xstream 1.2.2 ibm jdk 1.6 SR 8, xstream 1.3.1 (I tried those both with tomcat and with WebSphere server, so actually there are 6 configurations using IBM jdk). The code in question is in class com.thoughtworks.xstream.core.DefaultConverterLookup, around line 44. It uses an iterator from class com.thoughtworks.xstream.core.util.PrioritizedList, which uses a custom comparator, but all the comparator does is compare integers (the priorities). Has anyone seen this before? Any idea what can I do or change?

• iPhoneOS SDK - Remove Corner Rounding from views (iPad problem)

  - by norskben

  Hi Guys This might be a little bit picky, but in the iPad SplitViewController setup, there are 2 views. Each of the views has a very small black corner rounding. (This is probably the same with iPhone apps too). This rounding is visible in the image below. What I would like to do is remove the black rounding, so the UI doesnt get these two little bumps along the bottom. Has anyone done this, or know how to? -Its surely possible. Hopefully some one has seen this before. Thanks Image Link Mirror

• GData API works in Android 2.0 SDK & up?

  I used GData API to pull in Calender info. It works fine if I use 1.6. But the same code, if I change to Android 2.0 & up, it would throw AuthenticationException. Below is my code for ur ref: CalendarService myService = new CalendarService("My Application"); myService.setUserCredentials(args[0],args[1]); // Set up the URL and the object that will handle the connection: URL feedUrl = new URL("http://www.google.com/calendar/feeds/"+args[0]+"/private/full"); args[0] & args[1] are the credentials. AuthenticationException will be thrown when calling myService.setUserCredentials(). Anybody has any clue?

• iPhone SDK - How is data shared in a universal app

  - by norskben

  Stack overflow I want to make a universal version of my app available, but I am wondering how is data managed between the iPad and the iPhone versions? -Are they completely independent? or if I have a plist in the iPad app, does it also appear in the iPhone app. If so, is there any syncing etc etc. I have a few months experience with single iPad or iPhone apps, but never a universal. Thanks again. UPDATE: I was interested in the files in the /Documents folder, does this automatically update on itunes syncing at all?

• iPhone SDK allow touches to affect multiple views

  - by Parad0x13

  I have a main view that has has two buttons on it that control methods to display the next image and display the previous image. In this case the 'Image' is a class that inherits from UIImageView and has multiple pictures on it that you can interact with, and I call this class a 'Pane'. The pane itself handles all the user interaction itself while the main view controls the display of next and previous panes with the buttons. Here is my dilemma, because the pane fully covers the main view it wont allow for the user to tap the buttons on the main view! So once a pane pops up you cannot change it via the buttons! Is there a way to allow touches through transparent parts of a view, or if not how in the world do I achieve this?! I cannot pass touchesBegan or any of those methods from the pane to the superview because all of the button touch methods are created in the xib file. I cannot insert the pane under the control panel because then you wouldn't be able to interact with the pane. And as far as I know theres no way to pass touch events to every single pane within the paneHoldingArray that belongs to the main view I cannot add the command buttons inside of the pane because I want to be able to replace the command button's image with a thumbprint render of the next/previous pane. I've been stuck on this for a very long time, please somebody help me out with a fix action or a new way to re-engineer the code so that it will work!

• Facebook Graph API With iPhone SDK

  - by Tom G

  Hi, Has anyone been able to implement Facebooks Graph API in a native iPhone Application? The documentation is pretty sparse when it comes to iPhone integration, but the calls to get users information looks a lot more light weight than the previous method of using FBConnect. So i would like to use it. I have seen a few posts about but none explain you you would implement the login button as we did previously with FBConnect? If any one has achieved this or can offer me any pointers that would be brilliant Thanks Tom

• implementing stretchable dialog borders in iphone sdk

  - by Joey

  Hi, I want to implement dialog borders that scale to the size I require the dialog to be. Perhaps there is a better more conventional name for this sort of thing. If there is, if someone would edit the title, that'd be great. Anyhow, I'd like to do this so I can have dialogs of any size without the visual artifacts that come with scaling border art to small, large, or wacky unproportional dimentions. I have a few ideas on how this is done, but am not sure which is better for iphone. I have a few questions. 1) Should I make a containing view object that basically overloads its drawRect method and draws the images where they should be at their appropriate scale when the method is called, or should I main a containing view object that simply contains 8 UIImageViews? I suspect the latter approach won't work if I need to actively scale the resulting dialog class like in an animation. 1b) If overloading drawRect is the way to go, does someone have some sample code or a link to an example that demonstrates drawing an image directly from drawRect()? 2) Is it generally better to create a) a 3 x 3 image where the segments are in their appropriate 1x1 grid of the image? If so, is it simple to draw from a portion of this image onto my target view in drawRect (if the former assumption is correct that I should use drawRect)? b) The pieces separately in 8 different files?

• using crypto++ on iphone sdk with pycrypto on app engine

  - by Joey

  Hi, I'm trying to encrypt http requests using crypto++ and decrypt them with pycrypto on the app engine server end. Using Arc4 encryption, I can successfully encrypt and decrypt on the iphone end but when I try decrypting on app engine, the result is garbled. I thought maybe it has something to do with the encoding of the NSString but am not certain. It's not clear to me if I need to call encode() on the cipher on the server end before decrypting, although that does seem to resolve a failure to decrypt involving ascii values. I have a separate post that delves a bit into this. Can anyone offer some advice? http://stackoverflow.com/questions/2794942/crypto-pycrypto-with-google-app-engine
