要将pdf保存在文档目录中，请使用以下代码。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:@"data.pdf"];

        NSData *thedata = [NSData dataWithContentsOfURL:[NSURL URLWithString:`ADD URL OF PDF DATA`]];

        [thedata writeToFile:localFilePath atomically:YES];

用于检索代码下面的pdf用法。

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
            NSString *documentsDirectory = [paths objectAtIndex:0];
            NSString *localFilePath = [documentsDirectory stringByAppendingPathComponent:@"data.pdf"];
if ( [[NSFileManager defaultManager] fileExistsAtPath:localFilePath] ) {
            NSData *data = [NSData dataWithContentsOfFile:localFilePath];
        }
