获取文件各项属性方法
刚总结了下:
-(NSData *)applicationDataFromFile:(NSString *)fileName
{
NSArray *paths =NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);
NSString *documentsDirectory =[paths objectAtIndex:0];
NSString *appFile =[documentsDirectory stringByAppendingPathComponent:fileName];
NSData *data =[[[NSData alloc]initWithContentsOfFile:appFile]autorelease];
return data;
}
-(void)getFileAttributes
{
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *path = @"/1ct.rtf";
NSDictionary *fileAttributes = [fileManager fileAttributesAtPath:path traverseLink:YES];
NSLog(@"@@");
if (fileAttributes != nil) {
NSNumber *fileSize;
NSString *fileOwner, *creationDate;
NSDate *fileModDate;
//NSString *NSFileCreationDate
if (fileSize = [fileAttributes objectForKey:NSFileSize]) {
NSLog(@"File size: %qi\n", [fileSize unsignedLongLongValue]);
}
if (creationDate = [fileAttributes objectForKey:NSFileCreationDate]) {
NSLog(@"File creationDate: %@\n", creationDate);
//textField.text=NSFileCreationDate;
}
if (fileOwner = [fileAttributes objectForKey:NSFileOwnerAccountName]) {
NSLog(@"Owner: %@\n", fileOwner);
}
if (fileModDate = [fileAttributes objectForKey:NSFileModificationDate]) {
NSLog(@"Modification date: %@\n", fileModDate);
}
}
else {
NSLog(@"Path (%@) is invalid.", path);
}
}
