POPhoneGap plugin: AudioEncode success callback never called
text
Body
copied!<p>I'm using the AudioEncode plugin for PhoneGap (Cordova) on iOS. After updating a couple of lines for a newer version of Cordova, it appears to be correctly encoding wav files as m4a. In the Xcode console I see:</p> <pre><code>AVAssetExportSessionStatusCompleted doing success callback </code></pre> <p>When I look at the file system on the phone, the wav file has indeed become a m4a. However, the success callback (where I upload the file to a server) is never run. This is the relevant code in the plugin:</p> <pre><code>-(void) doSuccessCallback:(NSString*)path { NSLog(@"doing success callback"); NSString* jsCallback = [NSString stringWithFormat:@"%@(\"%@\");", self.successCallback, path]; [self writeJavascript: jsCallback]; [self.successCallback release]; } </code></pre> <p>My code in the app goes like this:</p> <pre><code>function encodeSuccess (path) { console.log('Audio encoded to M4A! Preparing to upload...') // file transfer code... } console.log('Preparing to encode audio file...') window.plugins.AudioEncode.encodeAudio(entry.fullPath, encodeSuccess, fail) </code></pre> <p>I'm assuming the <code>doSuccessCallback</code> function in the plugin needs to be updated, but I don't have experience with Objective C or PhoneGap plugins, so I'm stuck at this point. </p> <p>Any ideas?</p> <p><strong>UPDATE</strong></p> <p>In the Objective C function posted above, I tried logging <code>self.successCallback</code>, and it logged as <code><null></code>. Then I went up to the top of the main <code>encodeAudio</code> function, and the argument which is assigned to <code>self.successCallback</code> (<code>[arguments objectAtIndex:1]</code>) also logs as <code><null></code>. So, it seems to me that the callbacks are not being passed into the main function successfully. </p> <p>This is the AudioEncode.h file, maybe someone can spot the problem here:</p> <pre><code>@interface AudioEncode : CDVPlugin { NSString* successCallback; NSString* failCallback; } @property (nonatomic, retain) NSString* successCallback; @property (nonatomic, retain) NSString* failCallback; - (void)encodeAudio:(NSArray*)arguments withDict:(NSDictionary*)options; </code></pre>
