Question

请耐心等待我的努力我是第一次写自定义初始化， sentance01text 加载正常，所以我知道plist正在读取确定:)但我似乎无法让我的 sentance01Timing 时间工作＆GT;＆LT;

此方法应传递用户输入的 sentance01Timing ，这是objectForKey，它应将相关数组加载到 audioIntervals数组

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anyhelp将不胜感激。我不明白为什么它适用于文本而不是这个？ 终止 - 原因：' - [__ NSCFArray isFileURL]：

可能我正在做一些非常愚蠢的事情＆gt;＆lt;如果可以的话请帮忙 ps我不得不使用我的旧Mac（我的好一个正在被修复 - 所以将使用非弧 - 然后更新代码当我得到我的漂亮的mac回来，所以请记住它这就是为什么我现在不释放任何物品......）

非常感谢trojanfoe，我能够解决这个问题主要问题是我保留了初始化对象如果你确实在代码中看到了更好的方法，请说我的目标是学习（但宝贝步骤！这一切都很新!!）我在我的旧Mac笔记本电脑上做这个（所以它不是弧 - 因为我现在无法测试它）但也许它会帮助别人...

所以创建我的textmangerclass：

@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，它允许访问值访问器（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];

//希望我填充的实际例子可以帮助别人因为别人的错误让学习更有趣：P
