OBJECTIVE-C Foundation Framework Practice--nsstring (d) __foundation

#import <Foundation/Foundation.h> int main (int argc, const char * argv[]) {@autoreleasepool {/////////
    
    Read the file;//1. local files; 2. network file;//path class NSString *string11 = @ "http://www.baidu.com";
    
    Network path, should be read according to these two methods; Nsurl *httpurl = [Nsurl urlwithstring:string11];
    Local path;
    
    
    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);
    Write file NSString *string12 = @ "This is what needs to be written"; [String12 writetofile:@ "/users/chenyufeng/xcodeworkspace/nsstringdemo/nsstringdemo/readme.txt" atomically:true
    
    
    
Encoding:nsutf8stringencoding Error:nil];    
    
    
    return 0; }
}

The above method can be implemented to read files and write files.
