在IOS中怎么拿到自己相册中得图片-创新互联
//说明：法1：获取本地相册图片 法2：摄像头拍照设为图片
//步骤：一、声明代理
//二、声明两个私有的button 和 一个 UIImageView 分别为：1、获取手机本地相册图片btnLocalLibrary 2、获取拍照图片btnCamera 3、 p_w_picpathHead
//三、对声明的控件初始化
//四、实现两个GetLocalPhoto.m里面的三个函数 1、-(void)btnSelect1 2、-(void)btnSelect2 3、-(void)p_w_picpathPickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
