            },
            });

注意：
1.block中的self要在block外面声明成：
_ _weak typeof(self) weakSelf = self;
JS写法：var weakSelf = __weak(self);
2.for in循环改成for循环
3.多处用到实例变量的时候可以先声明再使用
如：var _homeHeaderView = weakSelf.valueForKey("_homeHeaderView");
4.获取屏幕宽度的方法：UIScreen.mainScreen().bounds().width
5.CGRectMake(0,0,5,10)写成{x:0,y:0,width:5,height:10}
