However, since these are initialised with the -initWithBool: method they round-trip back to JSON properly. In other words, they won't silently suddenly become 0 or 1; they'll be represented as 'true' and 'false' again. As an optimisation integers up to 19 digits in length (the max length for signed long long integers) turn into NSNumber instances, while complex ones turn into NSDecimalNumber instances. We can thus avoid any loss of precision as JSON allows ridiculously large numbers. @page objc2json Objective-C to JSON Objective-C types are mapped to JSON types in the following way: @li NSNull -> null @li NSString -> string @li NSArray -> array @li NSDictionary -> object @li NSNumber's -initWithBool:YES -> true @li NSNumber's -initWithBool:NO -> false @li NSNumber -> number @note In JSON the keys of an object must be strings. NSDictionary keys need not be, but attempting to convert an NSDictionary with non-string keys into JSON will throw an exception. NSNumber instances created with the -numberWithBool: method are converted into the JSON boolean "true" and "false" values, and vice versa. Any other NSNumber instances are converted to a JSON number the way you would expect. */ #import "SBJsonParser.h" #import "SBJsonWriter.h" #import "SBJsonStreamParser.h" #import "SBJsonStreamParserAdapter.h" #import "SBJsonStreamWriter.h" #import "NSObject+SBJson.h"
