xcode - linking dictionary to custom initialiser terminating - reason: '-[__NSCFArray isFileURL]: -

please patient im nuubie @ i'm writing custom init first time, sentance01text loads fine know plist reading ok :) cant seem sentance01timing timings work ><

this method should pass sentance01timing typed user objectforkey should load relevant array audiointervals array

at moment i'm using nsstring access dictionary , pass array audiointervals seems wrong , causes error anyhelp appreciated. dont understand why worked text not this? terminating - reason: '-[__nscfarray isfileurl]:

probably im doing dumb >< please if can ps having use old mac (my nice 1 being repaired @ moment - using non arc - updating code when nice mac back, keep in mind why im not releasing objects @ moment...)

audiotimings.plist

with many trojanfoe able fix problem main problem initialised objects wernt retained if see better way of things in code please goal learn (but baby steps! pretty new!!) im doing on old mac laptop (so not arc - cant test @ moment) maybe else...

so creating textmangerclass:

@interface textmanagerwithpagenum : cclayer  { //create properties need notice underscore  //nsstring *_varname; nsstring *_background; nsstring* _text;   //mytext nsstring* _soundfile; nsstring* _audiointerval; nsstring* _currpagenumber; } 

declare @property gives access value accessor (getter) , mutator (setter)

 //@property(nonatomic, strong)nsstring* background; - in arc  @property(nonatomic, retain) nsstring* background;  @property(nonatomic, retain) nsstring* text;  @property(nonatomic, retain) nsstring* soundfile;  @property(nonatomic, retain) nsstring* audiointerval;  @property(nonatomic, retain) nsstring* currpagenumber;  

and implementation .m

//@synthesize varname = _varname; @synthesize background = _background; @synthesize text = _text; @synthesize soundfile = _soundfile; @synthesize audiointerval = _audiointerval; @synthesize currpagenumber = _currpagenumber;   -(id)initwithbackground:(nsstring *)background          textfromplist:(nsstring *)text                    soundnamed:(nsstring *)soundfile       audiointervalplist:(nsstring *)audiointerval         currentpage:(nsstring *)currpagenumber   {   self = [super init];   if(self)   {     //_varname = varname;     _text = text;     _audiointerval = audiointerval;     _soundfile = soundfile;     _currpagenumber = currpagenumber;         /*here having problem - important manually retain       , dealloc or wont able use objects created!*/        //audio interval   _audiointerval= [[mydictionary objectforkey:audiointerval]retain];//***please retain me! , dont forget dealloc! :)   nslog(@"audio intervals %@",audiointerval); 

hello world

  textmanagerwithpagenum *mypage =    [[textmanagerwithpagenum alloc]initwithbackground:@"page01bg.png"textfromplist:@"page01text"soundnamed:@"page01" audiointervalplist:@"audiotimings" currentpage:5];                                                 [self addchild:mypage]; 

//hope practicle example of stuffed helps else since more fun learn elses mistakes :p
