请耐心等待，我是一个新手，我第一次编写自定义初始化，sentance01text加载正常，所以我知道 plist 读取正常 :) 但我似乎无法让我的sentance01Timing计时工作><

这个方法应该传递用户输入的sentance01Timing，它是objectForKey，它应该将相关数组加载到audioIntervals数组中

目前我正在使用 NSString 访问字典并将其传递给数组audiointervals 但这似乎是错误的并导致错误任何帮助将不胜感激。我不明白为什么它对文本有效，但不是这个？ 终止 - 原因：'-[__NSCFArray isFileURL]:

可能我在做一些非常愚蠢的事情><如果你可以请帮忙 ps 我不得不使用我的旧mac（我的好那个现在正在修理 - 所以将使用非弧 - 然后在我拿回我的漂亮mac时更新代码，所以请记住它为什么我现在不释放任何对象......）

非常感谢 trojanfoe，我能够解决问题，主要问题是如果您确实在代码中看到了更好的方法，我的初始化对象不会保留，请说我的目标是学习（但小步骤！一切都很漂亮新的！！）我在我的旧 Mac 笔记本电脑上做这个（所以它不是用于 arc - 因为我目前无法测试它）但也许它会帮助其他人......

所以创建我的文本管理器类：

@interface TextManagerWithpageNum : CCLayer 
{
//create the properties you need notice the underscore 
//NSString *_varName;
NSString *_background;
NSString* _text;   //myText
NSString* _soundFile;
NSString* _audioInterval;
NSString* _currPageNumber;
}

声明@property，它可以访问值访问器（getter）和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;

和实施.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 is where I was having the problem - its important to manually retain
      and dealloc or you wont be able to use your objects created!*/

      //audio interval
  _audioInterval= [[myDictionary objectForKey:audioInterval]retain];//***please retain me! and dont forget to dealloc! :)
  NSLog(@"audio Intervals %@",audioInterval);

你好世界

  TextManagerWithpageNum *Mypage = 
  [[TextManagerWithpageNum alloc]initWithBackground:@"Page01Bg.png"textFromPlist:@"Page01Text"soundNamed:@"Page01" audioIntervalPlist:@"AudioTimings" CurrentPage:5];                                               
 [self addChild:Mypage];

//希望我在哪里塞满的实际例子可以帮助别人，因为从别人的错误中学习更有趣：P
