OC_省市区字典

(一). 省市字典

1.创建文件接收路径.NSString *path = @"/Users/dlios/Desktop/新OC/OC08_字典/OC08_字典/area(省市版).txt";2.根据文件路径产生相应字符串.NSError *error = nil;NSString *str = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&error];// 判断如果错误出现,error不为空,打印错误信息.if(error) {    NSLog(@"%@", error);}NSLog(@"%@", str)3.将字符串切割成小的字符串放入数组中.NSArray *array = [str componentsSeparatedByString:"@\n"];4.创建省数组.NSMutableArray *provinceArray = [NSMutableArray array];5.遍历数组,找到符合条件的省名.for (NSString *tempStr in array) {    // 如果前缀没有空格.    if (![tempStr hasPrefix:@" "])    // 创建省字典.    NSMutableDictionary *provinceDictionary = [NSMutableDictionary dictionary];    // 把找到的省名放入省字典(用key值标记:forKey:@"provinceName").    [provinceDictionary setObject:tempStr forKey:@"provinceName"];    // 创建市数组.    NSMutableArray *cityArray = [NSMutableArray array];    // 把市数组放入省字典(用key值标记:forKey:@"cityArray").    [provinceDictionary setObject:cityArray forKey:@"cityArray"];    // 把省字典放入省数组.    [provinceArray addObject:provinceDictionary];} else {    // 找到省字典(省数组的最有一个位置).    NSMutableDictionary *provinceDictionaty = provinceArray.lastObject;    // 找到市数组(省字典中forKey:@"cityArray").    NSMutableArray *cityArray = provinceDictionary[@"cityArray"];    // 将市名添加到市数组.    [cityArray addObject:tempStr];    }}// 打印省数组.NSLog(@"%@", provinceArray);
