WordPress XML-RPC Framework

The WordPress XML-RPC library is a lightweight XML-RPC client for iOS and OS X.

It's based on Eric Czarny's Cocoa XML-RPC Framework, but without all the networking code, and a few additions of our own.


WordPress XML-RPC uses CocoaPods for easy dependency management.

Just add this to your Podfile and run pod install:

pod 'wpxmlrpc'

Another option, if you don't use CocoaPods, is to copy the WPXMLRPC folder to your project.


WordPress XML-RPC only provides classes to encode and decode XML-RPC. You are free to use your favorite networking library.

Building a XML-RPC request

NSURL *URL = [NSURL URLWithString:@"http://example.com/xmlrpc"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:URL];
[request setHTTPMethod:@"POST"];

WPXMLRPCEncoder *encoder = [[WPXMLRPCEncoder alloc] initWithMethod:@"demo.addTwoNumbers" andParameters:@[@1, @2]];
[request setHTTPBody:[encoder dataEncodedWithError:nil]];

Building a XML-RPC request using streaming

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *directory = [paths objectAtIndex:0];
NSString *guid = [[NSProcessInfo processInfo] globallyUniqueString];
NSString *streamingCacheFilePath = [directory stringByAppendingPathComponent:guid];

NSURL *URL = [NSURL URLWithString:@"http://example.com/xmlrpc"];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] initWithURL:URL];
[request setHTTPMethod:@"POST"];

NSInputStream *fileStream = [NSInputStream inputStreamWithFileAtPath:filePath];
WPXMLRPCEncoder *encoder = [[WPXMLRPCEncoder alloc] initWithMethod:@"test.uploadFile" andParameters:@[fileStream]];	      

[encoder encodeToFile:streamingCacheFilePath error:nil];

NSError *error = nil;
NSDictionary *attributes = [[NSFileManager defaultManager] attributesOfItemAtPath:filePath error:&error];
unsigned long contentLength = [[attributes objectForKey:NSFileSize] unsignedIntegerValue];
NSInputStream * inputStream = [NSInputStream inputStreamWithFileAtPath:filePath]; 

[request setHTTPBodyStream:inputStream];
[request setValue:[NSString stringWithFormat:@"%lu", contentLength] forHTTPHeaderField:@"Content-Length"];

Parsing a XML-RPC response

NSData *responseData = …
WPXMLRPCDecoder *decoder = [[WPXMLRPCDecoder alloc] initWithData:responseData];
if ([decoder isFault]) {
	NSLog(@"XML-RPC error %@: %@", [decoder faultCode], [decoder faultString]);
} else {
	NSLog(@"XML-RPC response: %@", [decoder object]);


The Base64 encoder/decoder found in NSData+Base64 is created by Matt Gallagher.

The original Cocoa XML-RPC Framework was developed by Eric Czarny and now lives at github.com/corristo/xmlrpc
