#import <Foundation/Foundation.h>int main(int argc, const char * argv[]) {  @autoreleasepool {        //////////////////////////        //讀取檔案;    //1.本地檔案;  2.網路檔案;    //路徑類    NSString *string11 = @"http://www.baidu.com";        //網路路徑;應該根據這兩種方法去讀取;    NSURL *httpUrl = [NSURL URLWithString:string11];        //本地路徑;    NSURL *localUrl = [NSURL fileURLWithPath:string11];            NSString *httpStr = [NSString stringWithContentsOfURL:httpUrl encoding:NSUTF8StringEncoding error:nil];    NSLog(@"httpStr = %@",httpStr);        NSString *localStr = [NSString stringWithContentsOfFile:@"/Users/chenyufeng/XcodeWorkspace/NSStringDemo/NSStringDemo/readme.txt" encoding:NSUTF8StringEncoding error:nil];    NSLog(@"localStr = %@",localStr);            //寫入檔案    NSString *string12 = @"這是需要寫入的內容";    [string12 writeToFile:@"/Users/chenyufeng/XcodeWorkspace/NSStringDemo/NSStringDemo/readme.txt" atomically:true encoding:NSUTF8StringEncoding error:nil];                            return 0;  }}


以上方法就可以實現讀取檔案和寫入檔案。
