Answer 1

我以前在使用错误定义的 URL 时见过这种情况。例如:

NSString *f = [NSTemporaryDirectory() stringByAppendingPathComponent:@"tmp.txt"];

// This is an invalid file url and will fail when you try to save to it.
NSURL *invalidFileURL = [NSURL URLWithString:f];

// This URL is acceptable.
NSURL *validFileURL = [NSURL fileURLWithPath:f isDirectory:NO];
