  • ObjC get property name

    - by Joe Even
    Yes. I've searched a lot without success. I've looking for a way to get a property name as StringValue from inside a method. Lets say: My class has X Subviews from the Type UILabel. @property (strong, nonatomic) UILabel *firstLabel; @property (strong, nonatomic) UILabel *secondLabel; [...] and so on. Inside the method foo, the views are iterated as followed: -(void) foo { for (UIView *view in self.subviews) { if( [view isKindOfClass:[UILabel class]] ) { /* codeblock that gets the property name. */ } } } The Result should be something like that: THE propertyName(NSString) OF view(UILabel) IS "firstLabel" I've tried class_getInstanceVariable, object_getIvar and property_getName without Success. For Example, the Code for: [...] property_getName((void*)&view) [...] RETURNS: <UILabel: 0x6b768c0; frame = (65 375; 219 21); text = 'Something'; clipsToBounds = YES; opaque = NO; autoresize = RM+BM; userInteractionEnabled = NO; layer = <CALayer: 0x6b76930>> But i'm looking for this kind of result: "firstLabel" , "secondLabel" and so on. Thanks for your help! Reagrds Joé

  • How do I call an Obj-C method from Javascript?

    - by gnfti
    Hi all, I'm developing a native iPhone app using Phonegap, so everything is done in HTML and JS. I am using the Flurry SDK for analytics and want to use the [FlurryAPI logEvent:@"EVENT_NAME"]; method to track events. Is there a way to do this in Javascript? So when tracking a link I would imagine using something like <a onClick="flurryTrackEvent("Click_Rainbows")" href="#Rainbows">Rainbows</a> <a onClick="flurryTrackEvent("Click_Unicorns")" href="#Unicorns">Unicorns</a> "FlurryAPI.h" has the following: @interface FlurryAPI : NSObject { } + (void)startSession:(NSString *)apiKey; + (void)logEvent:(NSString *)eventName; + (void)logEvent:(NSString *)eventName withParameters:(NSDictionary *)parameters; + (void)logError:(NSString *)errorID message:(NSString *)message exception:(NSException *)exception; + (void)setUserID:(NSString *)userID; + (void)setEventLoggingEnabled:(BOOL)value; + (void)setServerURL:(NSString *)url; + (void)setSessionReportsOnCloseEnabled:(BOOL)sendSessionReportsOnClose; @end I'm only interested in the logEvent method(s). If it's not clear by now, I'm comfortable with JS but a recovering Obj-C noob. I've read the Apple docs but the examples described there are all for newly declared methods and I imagine this could be simpler to implement because the Obj-C method(s) are already defined. Thank you in advance for any input.

  • Problems with creating and using of delegate-protocols

    - by Flocked
    Hello, I have the problem that I have created a delegate protocol, but the necessary methods are not executed, although I have implemented the protocol in my header file. Here are the detailed explanation: I created an instance of my ViewController (TimeLineViewController), which will be displayed. This ViewController contains a UITableView, which in turn receives the individual Cells / Rows from one instance of my TableViewCell. So the ViewController creates an instance of TableCellView. The TableViewCell contains a UITextView, which contains web links. Now I want, that not safari opens the links, but my own built-in browser. Unfortunately TableViewCell can not open a new ViewController with a WebView, so I decided to create a delegate protocol. The whole thing looks like this: WebViewTableCellDelegate.h: @protocol WebViewTableCellDelegate -(void)loadWeb; @end Then I created a instance WebViewDelegate in the TableViewCell: id <WebViewTableCellDelegate> _delegate; In the .m of the TableViewCell: @interface UITextView (Override) @end @class WebView, WebFrame; @protocol WebPolicyDecisionListener; @implementation UITextView (Override) - (void)webView:(WebView *)webView decidePolicyForNavigationAction:(NSDictionary *)actionInformation request:(NSURLRequest *)request frame:(WebFrame *)frame decisionListener:(id < WebPolicyDecisionListener >)listener { NSLog(@"request: %@", request); [_delegate loadWeb]; } @end - (void)setDelegate:(id <WebViewTableCellDelegate>)delegate{ _delegate = delegate;} And in my TimeLineViewController I implemented the protocol with < and the loadWeb-metode: - (void)loadWeb{ WebViewController *web = [[WebViewController alloc] initWithNibName:nil bundle:nil]; web.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController: web animated:YES]; [web release]; } And when the instance of the TableViewCell will be created in the TimelineViewController: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *MyIdentifier = @"MyIdentifier"; MyIdentifier = @"tableCell"; TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier]; if(cell == nil) { [[NSBundle mainBundle] loadNibNamed:@"TableViewCell" owner:self options:nil]; cell = tableCell;} [cell setDelegate:self]; //… } It is the first time I created a own delegate-protocol, so maybe there are stupid mistakes. Also I´m learnung Objective-C and programming generally only for 4 weeks. Thanks for your help! EDIT: I think i found the problem, but I dont know how to resolve it. I try to use [_delegate loadWeb]; in the subclass of the UITextView (because that is the only way i can react on the weblinks) and the subclass can´t use [_delegate loadWeb];. I tried this in a other methode and it worked.

  • Call a function from another Class - Obj C

    - by AndrewDK
    I'm trying to figure out how I can call a function from another one of my classes. I'm using a RootViewController to setup one of my views as lets say AnotherViewController So in my AnotherViewController im going to add in on the .h file @class RootViewController And in the .m file im going to import the View #import "RootViewController.h" I have a function called: -(void)toggleView { //do something } And then in my AnotherViewController I have a button assigned out as: -(void)buttonAction { //} In the buttonAction I would like to be able to call the function toggleView in my RootViewController. Can someone clarify on how I do this. I've tried adding this is my buttonAction: RootViewController * returnRootObject = [[RootViewController alloc] init]; [returnRootObject toggleView]; But I dont think that's right. Thanks in advanced.

  • Mixing libraries with and without RTTI with GCC on Mac OS X?

    - by Steve the Plant
    I've been banging my head on an issue and before I continue injuring myself some more, I'd like to confirm: Is it possible to have a GCC project that uses libraries that are compiled with and without RTTI? So, for example, I have project A (compiled without RTTI) that uses library B (compiled with RTTI) and library C (compiled without RTTI). In theory, is all that supposed to compile and link with no problems?

  • How can I simply change a class variable from another class in ObjectiveC?

    - by Daniel
    I simply want to change a variable of an object from another class. I can compile without a problem, but my variable always is set to 'null'. I used the following code: Object.h: @interface Object : NSObject { //... NSString *color; //... } @property(nonatomic, retain) NSString* color; + (id)Object; - (void)setColor:(NSString*)col; - (NSString*)getColor; @end Object.m: +(id)Object{ return [[[Object alloc] init] autorelease]; } - (void)setColor:(NSString*)col { self.color = col; } - (NSString*)getColor { return self.color; } MyViewController.h #import "Object.h" @interface ClassesTestViewController : UIViewController { Object *myObject; UILabel *label1; } @property UILabel *label1; @property (assign) Object *myObject; @end MyViewController.m: #import "Object.h" @implementation MyViewController @synthesize myObject; - (void)viewDidLoad { [myObject setColor:@"red"]; NSLog(@"Color = %@", [myObject getColor]); [super viewDidLoad]; } The NSLog message is always Color = (null) I tried many different ways to solve this problem, but no success. Any help would be appreciated.

  • How to use NSArray of NSArray object in objective c?

    - by user1306926
    I declared a NSArray object in .h file as @property (nonatomic, assign) NSArray *scnArray; and in .h file under - (void)viewDidLoad I created three different NSArray objects as NSArray *obj1 = [[NSArray alloc] initWithObjects:@"1",@"0",@"0",nil]; NSArray *obj2 = [[NSArray alloc] initWithObjects:@"0",@"3",@"0",nil]; NSArray *obj3 = [[NSArray alloc] initWithObjects:@"0",@"0",@"5",nil]; scnArray = [[NSArray alloc] initWithArray:obj1]; [scnArray arrayByAddingObjectsFromArray:obj2]; [scnArray arrayByAddingObjectsFromArray:obj3]; and if I access this scnArray from any other function NSArray *caseArray = [scnArray objectAtIndex:index];//index will be 0, 1, 2... I am getting BAD_ACCESS_ERROR. What is the problem here and how can I correct to use it?

  • press button to open web page from app

    - by Lee
    I have an app that I want to interact with a web page. Basically I want to press a button and the web page will open in a new view... Sorry I wasn't clear, I am developing on a Mac for an iPhone. Currently I have a "locate me" app that displays your Latitude and Longitude. I want to use those variables to populate 2 of the blanks on a PHP web page/form I have developed. I have added a label and button to my current app, when the button is pressed the URL with the Lat and Long (as passed vars) are displayed in the label. I want those vars to appear on my web page. Hope this is clearer... Solved: I just added these lines of code I found here: NSURL *url = [ [ NSURL alloc ] initWithString: @"http://www.cnn.com" ]; [[UIApplication sharedApplication] openURL:url];

  • Objective C code to handle large amount of data processing in iPhone

    - by user167662
    I had the following code that takes in 14 mb or more of image data encoded in base4 string and converts them to jpeg before writing to a file in iphone. It crashes my program giving the following error : Program received signal: “0”. warning: check_safe_call: could not restore current frame I tweak my program and it can process a few more images before the error appear again. My coding is as follows: // parameters is an array where the fourth element contains a list of images in base64 >encoded string NSMutableArray *imageStrList = (NSMutableArray*) [parameters objectAtIndex:5]; while (imageStrList.count != 0) { NSString *imgString = [imageStrList objectAtIndex:0]; // Create a file name using my own Utility class NSString *fileName = [Utility generateFileNName]; NSData *restoredImg = [NSData decodeWebSafeBase64ForString:imgString]; UIImage *img = [UIImage imageWithData: restoredImg]; NSData *imgJPEG = UIImageJPEGRepresentation(img, 0.4f); [imgJPEG writeToFile:fileName atomically:YES]; [imageStrList removeObjectAtIndex:0]; } I tried playing around with UIImageJPEGRepresentation and found out that the lower the value, the more image it can processed but this should not be the way. I am wondering if there is anyway to free up memory of the imageStrList immediately after processing each image so that it can be used by the next one in the line.

  • How to define colors in XCodes' Interface Builder?

    - by favo
    Hi, I would like to copy colors between elements in the interface builder or define them using RGB values. I.e. copy the background color of a button to another button without duplicating the button. Or: Enter an exact RGB code using the interface builder. Currently I can do this only programmatically but the interface builder is meant to design the GUI, so there must be such possibilities. Thank you all in advance for your answers.

  • Inconsistent Frame / Bounds of UIImage and UIScrollView

    - by iFloh
    this one puzzles me. I have an Image with a width of 1600 pixels and height of 1819 pixels. I load the image as UIImageView into an UIScrollView and set the "contentsize parameter" iKarteScrollView.contentSize = CGSizeMake(iKarteImageView.bounds.size.width, iKarteImageView.bounds.size.height); NSLog(@"Frame - width %.6f, height %.6f - Bounds - width %.6f, height %.6f", myImageView.frame.size.width, myView.frame.size.height, myImageView.bounds.size.width, myImageView.bounds.size.height); NSLog(@"Content size width %.6f, height %.6f", myScrollView.contentSize.width, myScrollView.contentSize.height); The NSLog shows the following: Frame - width 1600.000000, height 1819.000000 - Bounds - width 1600.000000, height 1819.000000 Content size width 1600.000000, height 1819.000000 Now comes the miracle, in a subsequent method of the same object I call the same NSLog again. But this time the result is Frame - width 405.000000, height 411.000000 - Bounds - width 1601.510864, height 1625.236938 Content size width 404.617920, height 460.000000 Why is the frame size suddely 405 by 411 pixels? How can the Bounds be 1601 by 1625 where 1625 is roughly 200 pixels less than the original size? When Positioning a further UIImageView at the coordinates of 20 by 1625, the UIImageView is displayed an estimated 200 pixels above the bottom of the content of the UIScrollView. I'm lost ...

  • How to check for an active Internet Connection on iPhone SDK?

    - by Brock Woolf
    I would like to check to see if I have an Internet connection on the iPhone using the Cocoa Touch libraries. I came up with a way to do this using an NSUrl. The way I did it seems a bit unreliable (because even Google could one day be down and relying on a 3rd party seems bad) and while I could check to see for a response from some other websites if Google didn't respond, it does seem wasteful and an unnecessary overhead on my application. - (BOOL) connectedToInternet { NSString *URLString = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://www.google.com"]]; return ( URLString != NULL ) ? YES : NO; } Is what I have done bad? (Not to mention 'stringWithContentsOfURL' is deprecated in 3.0) And if so what is a better way to accomplish this?
