Hi,
from the code listed I cannot tell if you alloc'ed memory for your
NSString at all?
What is the goal you try to achieve? If you just want to store a
single file path... with a global NSString do as along the lines of:
[rawFileName release];
rawFileName = [[NSString alloc] initWithString:[[files
objectAtIndex:i] stringByStandardizingPath]]];
Of course that will give you the last of the selected files stored in
the rawFileName string object. Alternatively you can use a mutable
string and replace the contents with the selected filename.
Maybe that helps to point you in the right directions ...

Hi Folks,
I think I am missing something really basic here with NSString. I
am trying to store the path of a user-selected file (from an
NSOpenPanel) internally so other routines can act on the data within
the file. Here's the relevant section of code:
if ([oPanel runModalForDirectory:nil file:nil types:nil] ==
NSOKButton)
{
NSArray * files = [oPanel filenames];
/* Process files */
for( i = 0; i < [files count]; i++ )
{
[rawFileName initWithString: [[files objectAtIndex:i]
stringByStandardizingPath]];
NSLog(@"Logging the file name variable");
NSLog(rawFileName);
NSLog(@"Logging the called file path object directly");
NSLog([[files objectAtIndex:i] stringByStandardizingPath]);
}
}
and this is the output from that section of code:
2009-05-26 09:18:41.931 REMI[19710:807] Logging the file name variable
2009-05-26 09:18:41.932 REMI[19710:807] Logging the called file path
object directly
2009-05-26 09:18:41.932 REMI[19710:807] /Users/vinai/Desktop/
rawTestData/P04608.7
rawFileName is declared to be an NSString * in my object's header
file. So why does printing out the string returned by the
stringByStandardizingPath function work okay, but not when
initializing an NSString * variable with it ? What would I need to
rawFileName so it can be used by other methods in my object ?
Thanks much all.
