docx, pdf, image, pptx 또는 인터넷에서 파일을 다운로드하는 방법

Question

인증을위한 자격 증명을 요구하는 사이트에서 docx, pdf, image, pptx 또는 파일을 다운로드하는 방법 자격 증명을 통과했지만 여전히 시도했습니다. nsdata의 데이터는 다른 것이지만 로컬에 생성 된 파일을 억지로 저장할 수 있기 때문에 모든 종류의 파일을 다운로드 할 수 있습니다. 다음과 같이

코드입니다 : 다른 파일 DownloadingFile.h

#import "MyAppDelegate.h" 

@interface DownloadingFile : NSObject 
{ 
    NSMutableData *webData; 
    NSMutableString *soapResults; 
    NSURLConnection *conn; 
    BOOL *elementFound; 
    BOOL isDoneParsing; 
    MyAppDelegate *mydelegate; 

    NSString *userCd,*passWord,*siteUrl; 

} 
@property (nonatomic ,retain) MyAppDelegate *mydelegate; 
-(void)buttonClicked; 
-(bool)getIsDone;

난 그냥 사용하여 테스트하는 간단한 응용 프로그램을 쓴 애플의 간단하고 강력한 솔루션 둘 다 NSURLConnection. 몇백 KB Word 및 PowerPoint 파일을 다운로드했습니다. 인증을 위해 .htaccess를 사용했습니다. 매력처럼 작동합니다. 다음은 관련 코드입니다. 좋은 작품 -

- (IBAction)clickedDownload:(id)sender { 
    NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://myserver.com/downloadTest/testfile.pptx"]]; 
    NSURLConnection *connection = [NSURLConnection connectionWithRequest:request delegate:self]; 
    [connection start]; 
} 

-(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { 
    // inform the user 
} 

-(void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge { 
    if ([challenge previousFailureCount] == 0) {   
     NSURLCredential *newCredential; 
     newCredential = [NSURLCredential credentialWithUser:@"theUsername" 
                password:@"thePassword" 
               persistence:NSURLCredentialPersistenceNone]; 
     [[challenge sender] useCredential:newCredential 
       forAuthenticationChallenge:challenge]; 
    } else { 
     [[challenge sender] cancelAuthenticationChallenge:challenge]; 
     // inform the user that password is incorrect 
    } 
} 

-(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response { 
    receivedData = [[NSMutableData alloc] init]; 
} 

-(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { 
    [receivedData appendData:data]; 
} 

-(void)connectionDidFinishLoading:(NSURLConnection *)connection { 
    NSURL *docDirectory = [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject]; 
    NSURL *filePath = [docDirectory URLByAppendingPathComponent:@"testfile.pptx"]; 
    [receivedData writeToURL:filePath atomically:YES]; 
    [receivedData release]; 
    connection = nil; 
}

당신은 ASIHTTPRequest에 보일 것입니다에서 호출이은 buttonClicked에 . http://allseeing-i.com/ASIHTTPRequest/How-to-use

NSURL *url = [NSURL URLWithString:@"http://abcdef.xyz.com/Docs/NewFolder/myFile.docx"]; 
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url]; 
[request setUsername:@"username"]; 
[request setPassword:@"password"]; 
[request setDidFinishSelector:@selector(requestDone:)]; 
[request setDidFailSelector:@selector(requestWentWrong:)]; 

- (void)requestDone:(ASIHTTPRequest *)request 
{ 
    NSString *response = [request responseString]; 
} 

- (void)requestWentWrong:(ASIHTTPRequest *)request 
{ 
    NSError *error = [request error]; 
}
