ARC语义问题“多个方法命名为”setRotation“而只存档 [英] ARC semantic issue "multiple methods named 'setRotation' " while archiving only

问题描述

我在cocos2dv3中的项目正在抛出 ARC Sematic Issue
多个名为setRotation：的方法在结果，参数类型或属性不匹配时发现
在归档（释放模式）时。它运行良好，同时部署到模拟器/设备（调试模式）。
在发布模式下，编译器在 UIRotationGestureRecognizer 和 CCNode 中执行旋转之间混淆。
当我在 CCBAnimationManager.m 中得到错误时，我将调用选择器setRotation的对象类型化为（ CCNode *），但是错误在 CCActionInterval 中出现。我希望在cocos2d库中有比任何地方更好的解决方案。

我做错了什么？

 
  @interface CCAction：NSObject< NSCopying> {
 id __unsafe_unretained _originalTarget; 
 id __unsafe_unretained _target; 
 NSInteger _tag; 
} 
 @property（nonatomic，readonly，unsafe_unretained）id target; 
 @property（nonatomic，readonly，unsafe_unretained）id originalTarget; 
 @property（nonatomic，readwrite，assign）NSInteger标签; 
  

in

  CCAction.m 
 @synthesize tag = _tag，target = _target，originalTarget = _originalTarget; 
 
 
  - （void）startWithTarget：（id）aTarget 
 {
 _originalTarget = _target = aTarget; 
} 
 
  - （void）startWithTarget：（id）aTarget 
 {
 _originalTarget = _target = aTarget; 
} 
  

类层次

  @interface CCActionFiniteTime：CCAction< NSCopying> 
 @interface CCActionInterval：CCActionFiniteTime< NSCopying> 
 @interface CCBRotateTo：CCActionInterval< NSCopying> 
 
 CCBRotateTo.m {
 
  - （void）startWithTarget：（CCNode *）aTarget 
 {
 [super startWithTarget：aTarget]; 
 startAngle_ = [self.target rotation]; 
 diffAngle_ = dstAngle_  -  startAngle_; 
} 
 
  - （void）update：（CCTime）t 
 {
 [self.target setRotation：startAngle_ + diffAngle_ * t]; 
} 
 
} 
  

解决方案

将您的cocos2dv3更新为最新版本（目前为RC4）。

我使用Xcode 5.0和cocos2dv3 RC1没问题。
但是更新Xcode到5.1我有这个问题。
因此我将cocos2dv3更新为RC4，现在工作正常。

您可以从此处。

My project in cocos2dv3 is throwing ARC Sematic Issue Multiple methods named 'setRotation:' found with mismatched result, parameter type or attributes while archiving(release mode). It runs fine while deploying to simulator/device (debug mode). In release mode compiler gets confused between the implementation of rotation in UIRotationGestureRecognizer and CCNode. When I got the error in CCBAnimationManager.m , I typecasted the object calling the selector setRotation to (CCNode*) but then the error crept up in CCActionInterval. I'm hoping there is a better solution than typecasting everywhere in cocos2d library.

What am i doing wrong? Thankyou for your time.

EDIT

@interface CCAction : NSObject <NSCopying> {
    id          __unsafe_unretained _originalTarget;
    id          __unsafe_unretained _target;
    NSInteger   _tag;
}
@property (nonatomic,readonly,unsafe_unretained) id target;
@property (nonatomic,readonly,unsafe_unretained) id originalTarget;
@property (nonatomic,readwrite,assign) NSInteger tag;

in

CCAction.m
@synthesize tag = _tag, target = _target, originalTarget = _originalTarget;


-(void) startWithTarget:(id)aTarget
{
    _originalTarget = _target = aTarget;
}

-(void) startWithTarget:(id)aTarget
{
    _originalTarget = _target = aTarget;
}

Class Hierarchy

@interface CCActionFiniteTime : CCAction <NSCopying> 
@interface CCActionInterval: CCActionFiniteTime <NSCopying>
@interface CCBRotateTo : CCActionInterval <NSCopying>

CCBRotateTo.m {

   -(void) startWithTarget:(CCNode *)aTarget
   {
      [super startWithTarget:aTarget];
      startAngle_ = [self.target rotation];
      diffAngle_ = dstAngle_ - startAngle_;
   }

   -(void) update: (CCTime) t
   {
      [self.target setRotation: startAngle_ + diffAngle_ * t];
   }

}

解决方案

update your cocos2dv3 to latest (RC4 for now).

I was using Xcode 5.0 and cocos2dv3 RC1 with no problem. But updating Xcode to 5.1 I had this problem. So I updated the cocos2dv3 to RC4 and now it's working fine.

You can find cocos 2d latest versions from here.
