Problem getting JSON contents with JSONValue
I am using the objective-c json framework to parse some json from the lighthouse api - http://stig.github.com/json-framework/
I've used the framework before with other apis with no issues although i seem to have come to a dead end when trying to grab the results from the lighthouse api using JSONValue.
It appears the value is being returned incorrectly:
NSArray *results = [json_string JSONValue];
for (NS开发者_JS百科Dictionary *project in results){
NSLog(@"project found");
}
This loop only runs once although i know there are atleast 7 objects for it to itterate through in the JSON string. project is also being set as a string and not a NSDictionary, i know this as calling objectForKey on project causes an error.
[NSCFString objectForKey:]: unrecognized selector sent to instance
I'm pretty stumped here and hope this isn't an issue with the string being returned from the Lighthouse api and i am just trying to get the contents incorrectly, my json string is here: http://pastie.org/1390233
The parser's behavior is correct. The dictionary results
contains only 1 key with the name projects
which is an array. To loop through each individual project, you need to enumerate this projects
property.
NSArray *projects = [results objectForKey:@"projects"];
for(NSDictionary *item in projects) {
NSDictionary *project = [item objectForKey:@"project"];
// now project should have the desired keys
}
