如何获取文件目录内部的目录URL路径

如何获取特定的目录URL路径？

比如Document/Art/

代码：

- (NSURL *)localRoot {
if (_localRoot != nil) {
    return _localRoot;
}

NSArray * paths = [[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask];

_localRoot = [paths objectAtIndex:0];
return _localRoot;
}

上面的代码可以获取Documents目录的路径，但是怎么获取ART的路径？

试试这个：

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *appFile_a = [documentsDirectory stringByAppendingPathComponent:@"/Art"];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *yourArtPath = [documentsDirectory stringByAppendingPathComponent:@"/Art"];

根据上面的回答
有一种简单的返回目录方法：

+ (NSString *) pathFor : (NSString *) directoryName{
    return [[NSSearchPathForDirectoriesInDomains(NSDocumentationDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:directoryName];
}

需要在ClassName.m中实现并且调用:

NSString *pathForDirectory = [ClassName pathFor:dirName]; //@"Art" in your case
