//步驟：一、聲明代理

//二、聲明兩個私有的button 和 一個 UIImageView 分別為：1、獲取手機(jī)本地相冊圖片btnLocalLibrary 2、獲取拍照圖片btnCamera 3、 p_w_picpathHead

//三、對聲明的控件初始化

//四、實現(xiàn)兩個GetLocalPhoto.m里面的三個函數(shù) 1、-(void)btnSelect1  2、-(void)btnSelect2  3、-(void)p_w_picpathPickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
