／＊字典转化为json字符串＊／

NSDictionary*baoJieDic=@{@"bookTime”:@“111”,@“carType”:@“222”,@“endAddress”:@“333”};

NSData *jsonData = [NSJSONSerialization dataWithJSONObject:baoJieDic options:NSJSONWritingPrettyPrinted error:nil];

NSString*str=[[NSString alloc]initWithData:jsonData encoding:NSUTF8StringEncoding];

／＊数组转化为json字符串＊／

NSMutableString *jsonString = [[NSMutableString alloc] initWithString:@"{"actorhalls":["];

for(NSArray *hall in self.dataArray){

//2. 遍历数组，取出键值对并按json格式存放

NSString *string;

string = [NSString stringWithFormat:

@"{"ownerName":"%@","ownerId":"%@","channelId":"%@","ownerType":"%@"},",hall[0],hall[1],hall[2],hall[3]];

[jsonString appendString:string];

}

// 3. 获取末尾逗号所在位置

NSUInteger location = [jsonString length]-1;

NSRange range = NSMakeRange(location, 1);

// 4. 将末尾逗号换成结束的]}

[jsonString replaceCharactersInRange:range withString:@"]}"];
