获取临时目录中文件的文件路径和URL

Question

我尝试获取名为"temp.pdf"的文件的文件路径,该文件位于NSTemporaryDirectory文件夹中(我已检查过,文件存在).

我用这个:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"temp" ofType:@"pdf" inDirectory:NSTemporaryDirectory()];

我尝试过:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"temp.pdf" ofType:@"" inDirectory:NSTemporaryDirectory()];

而且:

NSString *filePath = [[NSBundle mainBundle] pathForResource:@"temp" ofType:@"pdf"];

但似乎它不起作用,返回值始终为null.

所以,我有点困惑,有人可以帮助我吗？

谢谢.

Answer 1

NSTemporaryDirectory()提供临时目录的完整路径.而不是使用mainBundle你的尝试

NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"temp.pdf"];

如果您需要URL,请执行以下操作:

NSURL *furl = [NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:@"temp.pdf"]];

Answer 2

Swift 2.0

let tmpDirURL = NSURL.fileURLWithPath(NSTemporaryDirectory(),isDirectory: true)
let fileURL = tmpDirURL.URLByAppendingPathComponent("stuff").URLByAppendingPathExtension("gif")
print("FilePath: \(fileURL.path)")
