int main(int argc,
const char * argv[]) {

//准备工作

NSString *path =
@"/Users/dllo/Desktop/OC学习/oc06
－－
省市区字典/oc06 －－
省市区字典/area.txt";

// 根据路径产生相应的字符串.

NSString *str = [NSString
stringWithContentsOfFile:path encoding:NSUTF8StringEncoding
error:nil];

//对字符串进行切割.

NSArray *strArr = [str
componentsSeparatedByString:@"\n"];

//
创建一个省数组

NSMutableArray *proArr = [NSMutableArray
array];

for (NSString *temp
in strArr) {

if (![temp hasPrefix:@" "]) {

//
创建一个可变的省字典

NSMutableDictionary *proDic = [NSMutableDictionary
dictionary];

// 给省字典添加键值对

// 第一对:省名
[proDic
setObject:temp forKey:@"proName"];

//
第二对: 市数组创建一个市数组

NSMutableArray *cityArr = [NSMutableArray
array];
[proDic
setObject:cityArr
forKey:@"cityArr"];

//
把省字典添加到省数组中.
[proArr
addObject:proDic];

}else
if([temp hasPrefix:@" "] && ![temp
hasPrefix:@" "]){

// 创建一个市字典.

NSMutableDictionary *cityDic = [NSMutableDictionary
dictionary];

// 第一对 :市名
[cityDic
setObject:temp forKey:@"cityName"];

// 第二对:
区数组

NSMutableArray *zoneArr = [NSMutableArray
array];
[cityDic
setObject:zoneArr
forKey:@"zoneArr"];

//
找到对应位置添加到市数组.

//
先找到对应的省字典.

NSMutableDictionary *prodic = [proArr
lastObject];

// 再找对应的市数组.

NSMutableArray *cityArr = prodic[@"cityArr"];

//
最后把字典放在市数组中.
[cityArr
addObject:cityDic];
}else {

//
找到对应位置添加到区数组.

//
先找到对应的省字典.

NSMutableDictionary *prodic = [proArr
lastObject];

// 再找对应的市数组.

NSMutableArray *cityArr = prodic[@"cityArr"];

//
再找到对应的市字典.

NSMutableDictionary *cityDic = [cityArr
lastObject];

// 再找到区数组

NSMutableArray *zonearr = cityDic[@"zoneArr"];

// 再把temp放入
[zonearr
addObject:temp];
}
}

// fotin
遍历.
