iOS获取不同路径的方法

1.获取本地文件的路径

       NSString * location = @"/Users/qianfeng/Desktop/BB/UI/ 图片/未命名文件夹/lxl.jpg";

NSURL * url = [NSURL fileURLWithPath:location];

NSData * dadt = [NSData dataWithContentsOfURL:url];

self.imageView.image = [UIImage imageWithData:dadt];

2.获取网上的路径

        NSURL * url = [NSURL URLWithString:@"http://image.lxway.com/thumb/280x220/7/20/72080f282012a5e8e75de1117f1dcc49.jpg"];

NSData * data = [NSData dataWithContentsOfURL:url];

3.*访问网络的文本

         NSString * str = @"http://www.sina.com.cn/js/79/2013/0717/fix.js";

NSURL * url = [NSURL URLWithString:str];

NSString * data = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];

self.label.text = data;
