查找文件路径

//查找文件path:路径。 bundle：捆绑  mainBundle:主要包  pathForResource:路径是  ofType:类型//注意本地是initWithContentsOfFile  网络的是initWithContentsOfURL    NSString *path=[[NSBundle mainBundle]pathForResource:@"file"                                                      ofType:@"text"];        NSString *strContent=[[NSString alloc]initWithContentsOfFile:path                                                        encoding:NSUTF8StringEncoding                                                           error:nil];    NSLog(@"strContent =%@",strContent);    /*        NSLog(@"path=%@",path);//输出路径    NSURL *fileURL=[NSURL fileURLWithPath:path];//字符串转换成URL        NSError *error;//声明一个错误对象    //    NSString*strContent=[[NSString alloc]initWithContentsOfURL:fileURL                                                        encoding:NSUTF8StringEncoding                                                                       error:&error];    if (!strContent)//判断    {        NSLog(@"error:%@",[error localizedDescription]);    }                  NSLog(@"strConten =%@",strContent);//输出文本内容        NSString *httpPath=@"http://www.duowan.com";    NSURL * httpURL=[NSURL URLWithString:httpPath];    NSError *error2;//声明一个错误对象。    NSString *httpStr=[[NSString alloc]initWithContentsOfURL:httpURL                                                    encoding:NSUTF8StringEncoding                                                       error:&error2];    if (!httpStr)    {        NSLog(@"http : %@",[error2 localizedDescription]);            }    NSLog(@"strConten =%@",httpStr);
