总结：
/**
1. 按钮的风格：
    1）UIButtonTypeCustom-------用于自定义按钮
    2）UIButtonTypeRoundedRect-----白色圆角矩形
    3）UIButtonTypeDetailDisclosure---一种蓝色样式按钮
    4）UIButtonTypeInfoDark-------深色背景信息按钮
    5）UIButtonTypeInfoLight--------浅色背景信息按钮
    6）UIButtonTypeContactAdd------蓝色加号按钮

2.设置样式
    1）设置标题-----调用函数setTitle:(title) forState:(控件状态)
    2）设置标题颜色------btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    3）设置背景图片-----[btn setBackgroundImage:newIUmage forState:UIControlStateNormal];
    4）设置背景颜色------- btn.backgroundColor = [UIColor clearColor];
 3.添加响应
[btn  addTarget:self action:@selector(Action:) forControlEvents:UIControlEventTouchUpInside];
