如果有客观的档案,检查
原标题:check if a file exists objective-c

我使用了以下代码,以核实档案是否存在。

bool b=[[NSFileManager defaultManager] fileExistsAtPath:filePath];

守则涉及国际海洋观测系统。

...... 我把它迁移到ma湖X,

But I found whether the file exists on disk with filePath, b always returns 0, which means the file does not exists.

我想知道,奥塞斯与马科斯克斯之间是否有差别。

Welcome any comment

我想你用<条码>tilde重新使用。

http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSFileManager_Class/Reference/Reference.html#//apple_ref/occ/instm/NSFileManager/fileExistsAtPath:isDirectory:

<>12>

档案或目录。 如果开端是斜线(~),首先必须扩大这条路,以扼杀ByExpandingTildeInPath,或者这种方法将归还诺。

可通过打电话NS Carlo(@"%@”)查询;,如果存档的话。 途径是类型NSString
