将规整的字符串转化为字典型

#import "NSString+JSON.h"

#import <Foundation/Foundation.h>

@interface NSString (JSON)

+(NSDictionary *)parseJSONStringToNSDictionary:(NSString *)JSONString;

@end

@implementation NSString (JSON)

+(NSDictionary *)parseJSONStringToNSDictionary:(NSString *)JSONString {
    NSData *JSONData = [JSONString dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *responseJSON = [NSJSONSerialization JSONObjectWithData:JSONData options:NSJSONReadingMutableLeaves error:nil];
    return responseJSON;
}

@end

使用NSData，利用NSJSONSerialization将规整的类型转换为NSDictionary类型
