iOS 創建文件夾

原來的網址：http://blog.sina.com.cn/s/blog_86eee82e01018fe9.html

NSString *imageDir = [NSString stringWithFormat:@"%@/Caches/%@", NSHomeDirectory(), dirName];

BOOL isDir = NO;

NSFileManager *fileManager = [NSFileManager defaultManager];

BOOL existed = [fileManager fileExistsAtPath:imageDir isDirectory:&isDir];

if ( !(isDir == YES && existed == YES) )

{

[fileManager createDirectoryAtPath:imageDir withIntermediateDirectories:YES attributes:nilerror:nil];

}

刪除文件夾及文件級內的文件：

NSString *imageDir = [NSString stringWithFormat:@"%@/Caches/%@", NSHomeDirectory(), dirName];

NSFileManager *fileManager = [NSFileManager defaultManager];

[fileManager removeItemAtPath:imageDir error:nil];

- (void) moveAllDocs {
    NSFileManager *fileManager = [NSFileManager defaultManager];

    NSError *error = nil;

    NSString *sourceDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
    NSString *destinationDirectory = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) lastObject];

    NSArray *contents = [fileManager contentsOfDirectoryAtPath:sourceDirectory error:&error];

    for(NSString *sourceFileName in contents) {
        NSString *sourceFile = [sourceDirectory stringByAppendingPathComponent:sourceFileName];
        NSString *destFile = [destinationDirectory stringByAppendingPathComponent:sourceFileName];
        if(![fileManager moveItemAtPath:sourceFile toPath:destFile error:&error]) {
            NSLog(@"Error: %@", error);
        }
    }

}
