如何获取文件夹中文件的数量？

Question

如何获取iOS上文件夹中的文件数量？

Answer 1

NSFileManager *filemgr = [NSFileManager defaultManager];

NSArray *filelist= [filemgr directoryContentsAtPath: yourPath];

int count = [filelist count];

NSLog ("%i",count);

Answer 2

directoryContentsAtPath: 已弃用.

如果要获取Documents文件夹的文件数.

试着这个.

NSFileManager *fm = [NSFileManager defaultManager];
NSArray *docPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSArray *filelist= [fm contentsOfDirectoryAtPath:[docPaths objectAtIndex:0] error:nil];
int filesCount = [filelist count];
NSLog(@"filesCount:%d", filesCount);

Answer 3

- (NSArray *)directoryContentsAtPath:(NSString *)path已弃用.请- (NSArray *)contentsOfDirectoryAtPath:(NSString *)path error:(NSError **)error改用.这意味着Matt S的代码将变为:

NSFileManager * filemgr = [NSFileManager defaultManager];
NSArray * filelist = [filemgr directoryContentsAtPath:yourPath error:nil];
int count = [filelist count];
NSLog("%d", count);
