今天遇到一个问题，就是很多文件都是DB格式的，我们iOS开发需要将这个文件转化成我们需要的文件，首先如果你是苹果本下载SQLPro forSQLite软件，然后你就会打开一切DB文件，不需要任何辅助就能以json的格式导出，这样我们就可以用了，但是如果还觉得不够爽的话，就根据代码吧json转化成plist文件简单么
NSString *dataPath = [[NSBundle mainBundle] pathForResource:@"cityaddres2" ofType:@"json"];
NSData *data = [[NSFileManager defaultManager] contentsAtPath:dataPath];
NSError *error;
NSArray *questionnaireArr = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&error];
NSMutableDictionary *dic1 = [NSMutableDictionary dictionaryWithCapacity:10];
for (int i = 0; i < questionnaireArr.count; i ++) {
NSMutableDictionary *dic2 = [NSMutableDictionary dictionaryWithCapacity:10];
NSMutableArray *dataArr = [NSMutableArray arrayWithCapacity:10];
for (int j = 0; j < [questionnaireArr[i][@"city"] count]; j ++) {
[dic2 setObject:questionnaireArr[i][@"city"][j][@"area"] forKey:questionnaireArr[i][@"city"][j][@"name"]];
}
[dataArr addObject:dic2];
[dic1 setObject:dataArr forKey:questionnaireArr[i][@"name"]];
}
NSString *cachePatch = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)[0];
NSString *filePath = [cachePatch stringByAppendingPathComponent:@"newCity.plist"];
