Question

I get the data from an XML file and I am storing it in NSData object. I want to convert that NSData into an NSDictionary and store that data in a plist.

My code is as follows:

NSURL *url = [NSURL URLWithString:@"http://www.fubar.com/sample.xml"];
    NSData *data = [NSData dataWithContentsOfURL:url]; 
    NSLog(@"%@", data);

To convert the data, I am using:

- (NSDictionary *)downloadPlist:(NSString *)url {
    NSMutableURLRequest *request  = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:url] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:10]; 
    NSURLResponse *resp = nil;
    NSError *err = nil;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&resp error:&err];

    if (!err) {
        NSString *errorDescription = nil;
        NSPropertyListFormat format;
        NSDictionary *samplePlist = [NSPropertyListSerialization propertyListFromData:responseData mutabilityOption:NSPropertyListImmutable format:&format errorDescription:&errorDescription];

        if (!errorDescription)
            return samplePlist;

        [errorDescription release];              
    }

    return nil;
}

Can anyone please tell me how to do that?

Try this code:

NSString *newStr1 = [[NSString alloc] initWithData:theData1 encoding:NSUTF8StringEncoding];
NSString *newStr2 = [[NSString alloc] initWithData:theData2 encoding:NSUTF8StringEncoding];
NSString *newStr3 = [[NSString alloc] initWithData:theData3 encoding:NSUTF8StringEncoding];

NSArray *keys = [NSArray arrayWithObjects:@"key1", @"key2", @"key3", nil];
NSArray *objects = [NSArray arrayWithObjects:newStr1 , newStr2 , newStr3 , nil];
NSDictionary *dictionary = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

for (id key in dictionary) {
    NSLog(@"key: %@, value: %@", key, [dictionary objectForKey:key]);
}

NSString *path = [[NSBundle mainBundle] pathForResource:@"Login" ofType:@"plist"]; 
[dictionary writeToFile:path  atomically:YES];
//here Login is the plist name.

Happy coding
