iphone - JSON.framework add in xcode -
i have copy json.framework in
developer/platforms/iphonesimulator.platform/developer/sdks/iphonesimulator4.0.sdk/system/library/frameworks
/developer/platforms/iphoneos.platform/developer/sdks/iphoneos4.0.sdk/system/library/frameworks
both folder , importing
#import <json/sbjsonparser.h> but when using giving me linking error error command /developer/platforms/iphonesimulator.platform/developer/usr/bin/gcc-4.2 failed exit code 1

plz tell me wrong??
i wrote json-parser myself. can use if want copying code class source.
you use in way:
nsobject *obj = [self jsontoobj:yourjsonstring]; it returns nsdictionary, nsstring or nsarray depending on input. difference between parser , others is, accepts numerical keys, not allowed in json-standard. can't guarantee there no bugs in or works json-strings. please give me feedback, if works you!
