BlockLeaksKiller
新增两个宏，从编译期间避免block的循环引用
#define ZbWeakBlock(obj, block) ({__weak typeof(obj) weak##obj = obj; __weak typeof(weak##obj) obj = weak##obj; block;})
#define ZbWeakSelfBlock(block) ZbWeakBlock(self, block)
self.block = ZbWeakSelfBlock(^{
NSLog(@"访问self也不会循环引用：%@ - %@", self, weakself);
});
self.block();Example
以demo为例：
当发生内存泄漏时，会有弹窗提示
这时请看控制台的输出：
复制内存泄漏对象地址：
打开Xcode内存图功能：
粘贴内存泄漏对象地址进行查找过滤：
鼠标右键箭头所指向的block->点击Print Description：
查看控制台的输出：
复制红线命令，粘贴至lldb：
红框部分就是block导致循环引用的代码定义处，请自行跳转代码进行修复.
