POiPhone SDK - instance variable out of scope issue
text
Body
copied!<p>I am getting crazy over this error. Compiler is saying out of scope for an instance NSSString variable. Never had this thing before and used thousands of NSString instance variables!</p> <p>Here is my class .h file</p> <pre><code>#import <UIKit/UIKit.h> #import <AVFoundation/AVFoundation.h> #import <CoreAudio/CoreAudioTypes.h> #import "Snapshot.h" @interface RecordAudioViewController : UIViewController <AVAudioRecorderDelegate, AVAudioPlayerDelegate> { NSString *filename; } @property (nonatomic, retain) NSString *filename; - (IBAction) recordAudio; - (IBAction) playAudio; @end </code></pre> <p>Variable is synthesized properly. I initalize filename variable in viewDidLoad method. I want to use it in IBAction method recordAudio, but compiler always says out of scope? Why is that, is this a bug or something?</p> <p>Here is .m code. viewDidLoad method where I set the filename instance variable:</p> <pre><code>- (void)viewDidLoad { [super viewDidLoad]; </code></pre> <p>NSString *tmpDir = NSTemporaryDirectory(); filename = [NSString stringWithFormat: @"%.0f.%@", [NSDate timeIntervalSinceReferenceDate] * 1000.0, @"caf"]; NSLog(filename); }</p> <p>And the IBAction method</p> <pre><code>- (IBAction) recordAudio { NSLog(filename); // here I get out of scope message when moving over with mouse cursor and when steping over this line EXC_BAD_ACCESS } </code></pre> <p>The entire .m file can be seen here: <a href="http://pastie.org/1021993" rel="nofollow noreferrer">http://pastie.org/1021993</a></p>
