Reading downloaded file objective-c - iphone

Question

I am trying to read text file downloaded from my server.
-(void)downloadFile
{
NSURLRequest request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://myserver.com/website/file.txt"]];
AFURLConnectionOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:#"file.txt"];
operation.outputStream = [NSOutputStream outputStreamToFileAtPath:filePath append:NO];
[operation setCompletionBlock:^{
NSLog(#"downloadComplete!");
NSString *path;
path = [[NSBundle mainBundle] pathForResource: #"file" ofType: #"txt"];
NSString *data = [self readFile: path];
NSLog(#"%#",data);
}];
[operation start];
}
-(NSString *)readFile:(NSString *)fileName
{
NSLog(#"readFile");
NSString *appFile = fileName;
NSFileManager *fileManager=[NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:appFile])
{
NSError *error= NULL;
NSString *resultData = [NSString stringWithContentsOfFile: appFile encoding: NSUTF8StringEncoding error: &error];
if (error == NULL)
return resultData;
}
return NULL;
}
It downloads the file successfully but I can't read file. Returns null. Probably I can't set file path correctly. I want to read file from device disk, not project bundle.

Answer 1

Change
path = [[NSBundle mainBundle] pathForResource: #"file" ofType: #"txt"];
to
path = filePath;

Answer 2

I made your stuff work, i dont know if you still need it
-(void)downloadFile
{
CNMRouter *routext;
routext = ((LDAppDelegate *)[UIApplication sharedApplication].delegate).router;
[[[Singleton sharedClient]httpClient] setParameterEncoding:AFFormURLParameterEncoding];
NSMutableURLRequest *request;
if([routext postOrGet]){
request = [[[Singleton sharedClient]httpClient] requestWithMethod:#"GET"
path:[routext getLoginURLPath:#"admin" andPassword:#"admin"]
parameters:nil];
}else{
request = [[[Singleton sharedClient]httpClient] requestWithMethod:#"POST"
path:[routext getBackupUrl]
parameters:[routext getBackupURLPath]];
}
// NSURLRequest request = [NSURLRequest requestWithURL:[NSURL URLWithString:#"http://myserver.com/website/file.txt"]];
AFURLConnectionOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];
[operation setCompletionBlock:^{
NSLog(#"downloadComplete!");
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"%#", [paths objectAtIndex:0]);
NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:#"file.txt"];
// operation.outputStream = [NSOutputStream outputStreamToFileAtPath:filePath append:NO];
NSString *path;
// path = [[NSBundle mainBundle] pathForResource: #"file" ofType: #"txt"];
path = filePath;
NSString *data = [self readFile: path];
NSLog(#"%#",data);
}];
[operation start];
}
I moved some stuf from its place but basicaly you were trying to get your file before it was even downloaded so i just put some stuff inside the succes block. Its working for me, thank you!
