YAJL-JSON-Objective-C-Parser

YAJLParserOperation is an NSOperation subclass for streaming JSON Parsing using YAJL.

To use this in your project:

1. Integrate the YAJL Library into your Objective C Project. You can find it at http://github.com/gabriel/yajl-objc
2. Copy the .h and .m files into your project.

a. Import. #import "YAJLParserOperation.h"

b. Instantiate.

YAJLParserOperation *feedParserOperation = [[YAJLParserOperation alloc] initWithURL:[NSURL URLWithString:@"http://some-url"]]; [operationQueue addOperation:feedParserOperation]; [feedParserOperation addObserver:self forKeyPath:@"isFinished" options:NSKeyValueObservingOptionNew context:NULL];

c. Observe a notification when the parsing is done.

• (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context { if ([object isKindOfClass:[YAJLParserOperation class]]) { YAJLParserOperation *feedParserOperation = (YAJLParserOperation *)object; [feedParserOperation removeObserver:self forKeyPath:@"isFinished"]; if( [feedParserOperation error] ) { NSLog(@"Failed!"); } else { NSLog(@"Success!"); YAJLDocument *document = [[feedParserOperation document] retain]; // Now process document; } } }
