オブジェクトをインスタンス化しようとすると、TyphoonComponentFactory.m でクラッシュが発生します - この行は EXC_BAD_ACCESS でクラッシュします:

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

または時々これ：

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

すべての変数 (プール、インスタンス、定義) は、デバッガーでクラッシュ時に正しく表示されます。プログラムの実行の早い段階で (ただし、それほど前ではなく、つまり同じ実行ループ)、TyphoonComponentFactory をセットアップし、それをデフォルトのファクトリにしました。これを引き起こしている可能性のあるものはありますか？ファクトリの作成が発信者にとって遅すぎるという漠然とした理論がありましたが...かなり弱いです。

さらに更新:

Typhoon はデフォルトで TyphoonScopeObjectGraph に設定されているようですが、これは明らかにスレッドセーフではありません。すべての非シングルトンを TyphoonScopePrototype に切り替え、59 行目の TyphoonCallStack -pop でクラッシュが発生するようになりました[_storage removeLastObject]。ある種の例外のようですが、デバッガーは有用なものを何も吐き出しません。

これが私たちの解決策です。これはかなりうまくいくようです：

#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

また、すべてのスコープを Singleton または Prototype として宣言します。
