下面展示block 的两种调用方式

- (void)test{

    void (^block1)(int) = ^(int a){
         NSLog(@"block1 %d",a);
    };
    
    //type1
    block1(1);
    
    //type2
    //获取block类型对应的方法签名。
    NSMethodSignature *signature = aspect_blockMethodSignature(block1);
    NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature];
    [invocation setTarget:block1];
    int a=2;
    [invocation setArgument:&a atIndex:1];
    [invocation invoke];
}
