我的NSDocumentsDirectory中保存了一些文件,如何获取这些文件的名称,然后在uitableview中显示这些名称?
我只想将对象的名称检索为NSString,就可以将文件检索为对象,但不能检索其名称。
这是它的代码:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSError * error;
objectsAtPathArray = (NSMutableArray*)[[NSFileManager defaultManager]
contentsOfDirectoryAtPath:documentsDirectory error:&error];
[objectsAtPathArray removeObjectAtIndex:0];
最后一行是删除.DS_Store文件
最佳答案
试试这个,
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
objectsAtPathArray = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil]mutableCopy];
for(int i = 0; i < [objectsAtPathArray count]; i++)
{
if (![[objectsAtPathArray objectAtIndex:i]isEqualToString:@".DS_Store"])
{
[NewArray addObject:[objectsAtPathArray objectAtIndex:i]];
NSLog(@"NewArray=%@",[NewArray objectAtIndex:i]);
}
}
