Q : __weak typeof(self) weakSelf = self 是什么意思？
A : block对于其变量都会形成strong reference，对于self也会形成strong reference ，
而如果self本身对block也是 strong reference 的话，就会形成 strong reference 循环，造成内存泄露，
为了防止这种情况发生，在block外部应该创建一个weak（__block） reference
所以在block内如果有self的话，一般都会在block外面加一句 __weaktypeof(self) weakSelf =self;
