iphone - 在iphone中获取文档目录文件日期修改时间

Question

NSArray *documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *currDircetory = [documentPath objectAtIndex:0];
NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:currDircetory  error:nil];
for (NSString *s in filePathsArray){
        NSLog(@"file %@", s);
}

现在我使用上面的代码从文档目录中获取文件列表现在我想知道如何获取文档目录中文件的修改时间。

你可以使用这个:

NSArray *documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *currDircetory = [documentPath objectAtIndex:0];
NSArray *filePathsArray = [[NSFileManager defaultManager] subpathsOfDirectoryAtPath:currDircetory  error:nil];

for (NSString *s in filePathsArray){

    NSString *filestring = [currDircetory stringByAppendingFormat:@"/%@",s];
    NSDictionary *filePathsArray1 = [[NSFileManager defaultManager] attributesOfItemAtPath:filestring error:nil];
    NSLog(@"Modified Day : %@", [filePathsArray1 objectForKey:NSFileModificationDate]);
}
