文件管理的相关操作
1.获取文件管理器
NSFileManager * fileManager = [NSFileManager defaultManager];
NSString * path = @"/Users/aplle/Desktop/test.txt";
NSError * error;
NSDictionary * dic = [fileManager attributesOfItemAtPath:path error:&error];
NSLog(@"dic %@",dic);
if (error == nil)
{
NSDate * date = [dic objectForKey:NSFileCreationDate];
NSString * size = [dic objectForKey:NSFileSize];
NSLog(@" date = %@, size = %@",date,size);
}
2、创建目录
NSFileManager * fileManager = [NSFileManager defaultManager];
NSString * path = @"/Users/aplle/Desktop/myfolder/aaa";
NSError * error;
//withIntermediateDirectories YES 逐级创建文件夹,NO表示只能够创建一级目录
BOOL isCreateSuccess = [fileManager createDirectoryAtPath:path withIntermediateDirectories:YES attributes:nil error:&error];
if (isCreateSuccess)
{
NSLog(@"创建成功");
}
else
{
NSLog(@"error %@",error);
}
3、 移动目录 移动就是剪切操作
NSFileManager * fileManager = [NSFileManager defaultManager];
NSString * path = @"/Users/aplle/Desktop/myfolder";
NSString * pathTo = @"/Users/aplle/Desktop/newmyfolder";
NSError * error ;
BOOL isMoveSuccess = [fileManager moveItemAtPath:path toPath:pathTo error:&error];
if (isMoveSuccess)
{
NSLog(@"移动成功");
}
else
{
NSLog(@"error %@",error);
}
*/
4、.删除
NSFileManager * fileManager = [NSFileManager defaultManager];
NSString * path = @"/Users/aplle/Desktop/newmyfolder";
NSError * error;
BOOL isRemoveSuccess = [fileManager removeItemAtPath:path error:&error];
if (isRemoveSuccess)
{
NSLog(@"删除成功");
}
else
{
NSLog(@"erro %@",error);
}
5、拷贝文件
NSFileManager * fileManager = [NSFileManager defaultManager];
NSString * path = @"/Users/aplle/Desktop/myfolder";
NSString * pathTo = @"/Users/aplle/Desktop/newmyfolder";
NSError * error;
BOOL isCopySuccess = [fileManager copyItemAtPath:path toPath:pathTo error:&error];
if(isCopySuccess)
{
NSLog(@"拷贝成功");
}
else
{
NSLog(@"error %@",error);
}
