ios 從URL中截取所包含的參數,而且以字典的形式返回和參數字典轉URL

//字典轉連接（參數）

- (NSString *)keyValueStringWithDict:(NSDictionary *)dict

{ if (dict == nil) { return nil; } NSMutableString *string = [NSMutableString stringWithString:@"?"]; [dict enumerateKeysAndObjectsUsingBlock:^(id key, id obj, BOOL *stop) { [string appendFormat:@"%@=%@&",key,obj]; }]; if ([string rangeOfString:@"&"].length) { [string deleteCharactersInRange:NSMakeRange(string.length - 1, 1)]; } return string; } //連接轉字典 （參數） -(NSDictionary *)dictionaryWithUrlString:(NSString *)urlStr { if (urlStr && urlStr.length && [urlStr rangeOfString:@"?"].length == 1) { NSArray *array = [urlStr componentsSeparatedByString:@"?"]; if (array && array.count == 2) { NSString *paramsStr = array[1]; if (paramsStr.length) { NSMutableDictionary *paramsDict = [NSMutableDictionary dictionary]; NSArray *paramArray = [paramsStr componentsSeparatedByString:@"&"]; for (NSString *param in paramArray) { if (param && param.length) { NSArray *parArr = [param componentsSeparatedByString:@"="]; if (parArr.count == 2) { [paramsDict setObject:parArr[1] forKey:parArr[0]]; } } } return paramsDict; }else{ return nil; } }else{ return nil; } }else{ return nil; } }
