DIY iPad Horizontal Stand for $3




I figured out a way to adapt an existing iPad dock to allow horizontal viewing. Target, Walmart, and other places sell these great wall hooks... http://solutions.3m.com/wps/portal/3M/en_US/Command/home/

I bought a set of the small wire hooks for $2.94 from Target. Adjusted the angle of the hook to match the ipad dock angle and attached them to the back of my iPad dock.

They work great! Plus its not permanent! Check out the pics and leave a comment if you end up using this.

Cheers!

Drupal for iPhone app Update - Upload Images to Drupal from iPhone

This one took a while to figure out...

Step 1) Create the File.Save Service
Drupal will accept your image encoded as base64 and dump into an actual file.
http://drupal.org/node/376226

Step 2) The iPhone will take a picture and then encode it as base64. I figured out that although the CocoaXMLRPC library will send the XMLRPC response with < base64 > tags, drupal doesn't know what to do with the info in those tags. This created a lot of 0 byte files.
The solution is to comment out the < base64 > tag in the CocoaXMLRPC and substitute < string > tag.

If everything works, you'll get a File ID (fid) back.

So construct your XMLRPC Request like you would with a text content type. Then set your Imagedata as one of the PostParams with the forkey 'file' and the method file.save.

Drupal for iPhone app Update - NSSCanner no more

I figured out that the Cocoa XMLRPC library was already doing the work of parsing out the XMLRPC responses. Basically after you get the XMLRPC response, create a NSDictionary and retrieve the key/value pair. Here's some sample code

//So you could put this in the - (void)viewDidLoad
//URL
NSString *drupalurl = @"http://www.drupalwebsite.com/services/xmlrpc";

//XMLRPC request
XMLRPCRequest *reqUserInfo = [[XMLRPCRequest alloc] initWithHost:[NSURL URLWithString:drupalurl]];
[reqUserInfo setMethod:@"system.connect" withObjects:[NSArray arrayWithObjects: nil]];
XMLRPCResponse *Response = [XMLRPCConnection sendSynchronousXMLRPCRequest:reqUserInfo];

//Whole XMLRPC response dumped into dictionary.
NSMutableDictionary *dict = [Response object];

//Anonymous sessid retrieved from the dictionary
NSString *anonsessid = [dict objectForKey:@"sessid"];

VOILA!!
