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获取文件列表现在我想知道如何在文档目录中获取文件的修改时间.

谢谢,

Answer 1

你可以用这个:

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]);
}

Answer 2

NSFileManager* filemngr = [NSFileManager defaultManager];

NSDictionary* attributes = [filemngr attributesOfItemAtPath:path error:nil];

if (attributes != nil) {

    NSDate *date = (NSDate*)[attributes objectForKey:NSFileModificationDate];
} else {

    NSLog(@"File Not found !!!");
}
