Objective c 在“台风”中创建对象时崩溃

objective-c

Objective c 在“台风”中创建对象时崩溃,objective-c,typhoon,Objective C,Typhoon,我在尝试实例化一个对象时，在typhoncomponentfactory.m中遇到一个崩溃-这一行在EXC_BAD_访问时崩溃： 279:[pool setObject:instance forKey:definition.key]; 或者有时候这个： 276:id instance = [pool objectForKey:definition.key]; 所有变量-池、实例、定义，都在调试器中查看崩溃的时间。在程序执行的早期（但不是更早，即相同的runloop），我已经设置了我的Typh

我在尝试实例化一个对象时，在typhoncomponentfactory.m中遇到一个崩溃-这一行在EXC_BAD_访问时崩溃：

279:[pool setObject:instance forKey:definition.key];

或者有时候这个：

276:id instance = [pool objectForKey:definition.key];

所有变量-池、实例、定义，都在调试器中查看崩溃的时间。在程序执行的早期（但不是更早，即相同的runloop），我已经设置了我的TyphonComponentFactory，并将其设置为默认工厂。有什么可能导致这种情况吗？我有一个模糊的理论，那就是这个工厂对来访者来说太晚了，但是。。。很弱

台风版本1.8.2。下面是大会：

        [definition setScope:TyphoonScopeSingleton];

    }];

}

堆栈跟踪，对于第276行上的崩溃：

进一步更新：

看起来Typhone默认为TyphonScopeObjectGraph，这显然不是线程安全的。我们将所有非单例都切换到了TyphonScopePrototype，现在我们在第59行的TyphonCallStack-pop中遇到崩溃。似乎是某种例外，但调试器没有吐出任何有用的东西。

无法对您的帖子发表评论（声誉不够）：

是的，如果您从不同的线程创建组件-这可能是崩溃的原因。Typhone现在不是线程安全的（在对象创建期间，我们使用的是非线程安全的NSMutableArray和NSMutableDictionary）

您可以通过将typhone调用包装到串行队列或synchronized语句中来修复它。。或者我们可以在Typhone内部完成（但这将是Typhone 2.0的功能-很难同时维护两个版本）

更新：

台风2.0现在是线程安全的

这是我们的解决方案，似乎效果不错：

#import "TyphoonComponentFactory+SwizzledObjectForDefinition.h"
#import "JRSwizzle.h"

@implementation TyphoonComponentFactory (SwizzledObjectForDefinition)

+ (void)swizzleMethods
{
    SEL objectForDefinitionSelector = sel_registerName("objectForDefinition:");
    [TyphoonComponentFactory jr_swizzleMethod: objectForDefinitionSelector
                                   withMethod: @selector(swizzledObjectForDefinition:)
                                        error: nil];
}

// Synchronize objectForDefinition
- (id)swizzledObjectForDefinition:(TyphoonDefinition *)definition
{
    @synchronized(self) {
        return [self swizzledObjectForDefinition:definition];
    }
}

@end

我们还将所有作用域声明为Singleton或Prototype。

您使用的是什么版本的Typhone？你的程序集看起来像什么？添加了程序集和版本。一些问题：当崩溃发生时，你能发布堆栈跟踪吗？（特别是台风框架部分，从坠机线到坠机地点）。

池

、

实例

和

定义

有哪些值？台风正试图建造哪些物体？你在台风中看到几条线了吗？（台风应该主要是线程安全的，但事故会发生）。添加堆栈跟踪和所有其他信息。在这个例子中，我看到主线程也在访问Typhone的东西，但情况并非总是如此。我们已经找到了问题的线索——默认情况下，所有内容都显示为TyphonScopeObjectGraph。由于这不是线程安全的，而且我们在后台做了很多事情，我们看到了很多崩溃。这是我们这边的已知问题还是配置问题？啊。好的，我们将尝试将typhoncomponentfactory-objectForDefinition:包装到@synchronized块中。将所有调用放入串行队列对我们来说不是一个好的解决方案，因为我们使用了许多创建这些对象的NSOperationQueue对象。根据您的测试，仅仅将所有作用域作为Singleton或Prototype是不够的？不，它崩溃得很厉害。
