ARC環境でメモリリークを起こす

７つの方法

①循環参照

@interface Hoge : NSObject@property (strong, nonatomic) Hoge *hoge;@end@implementation Hoge@end

Hoge *h = [[Hoge alloc] init]; h.hoge = h;

②MEMCPY

Hoge *h = [[Hoge alloc] init]; memset(&h, 0, sizeof(id));

③OBJC_MSGSEND

Hoge *h = [[Hoge alloc] init]; objc_msgSend(h, NSSelectorFromString(@"retain"));

④CFRETAIN

Hoge *h = [[Hoge alloc] init]; CFRetain((__bridge CFTypeRef)h);

⑤__BRIDGE_RETAINED

Hoge *h = [[Hoge alloc] init]; void *p = (__bridge_retained void *)h;

⑥CLASS_REPLACEMETHOD

Hoge *h = [[Hoge alloc] init]; class_replaceMethod( [Hoge class], NSSelectorFromString(@"release"), imp_implementationWithBlock(^(){}), "");

⑦MACH_OVERRIDE

どうもC言語の関数を書き換えるらしい。面白そうだけど難しそう！誰か教えて！

タブーをあえてやるのも面白い！
