Get file path and URL for file in temp directory
提问by HasgardLucian
I try to get the file path of a file called "temp.pdf" wich is located in the NSTemporaryDirectory folder (I've checked, the file exists).
我尝试获取位于 NSTemporaryDirectory 文件夹中的名为“temp.pdf”的文件的文件路径（我已经检查过，该文件存在）。
I use this :
我用这个：
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"temp" ofType:@"pdf" inDirectory:NSTemporaryDirectory()];
I've tried with :
我试过：
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"temp.pdf" ofType:@"" inDirectory:NSTemporaryDirectory()];
And :
和 ：
NSString *filePath = [[NSBundle mainBundle] pathForResource:@"temp" ofType:@"pdf"];
But it seems that it doesn't work, return value is always null.
但是好像不行，返回值总是空的。
So, i'm a little confused, someone can help me ?
所以，我有点困惑，有人可以帮助我吗？
Thank you.
谢谢你。

NSTemporaryDirectory()provides a full path to the temporary directory. Instead of using your mainBundlehave you tried
NSTemporaryDirectory()提供临时目录的完整路径。而不是使用你mainBundle有你试过
NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"temp.pdf"];
If you need a URL instead, do this:
如果您需要一个 URL，请执行以下操作：
NSURL *furl = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:@"temp.pdf"]];
