I thought to implement an open panel on my main window and expected

// Put up the sheet for and retrieve the return value.
[panel beginSheetForDirectory:nil
file:nil
types:nil
modalForWindow:aWindow
modalDelegate:self
didEndSelector:@selector(openSheetDidEnd:returnCode:contextInfo:)
contextInfo:nil];
// If we have a file path the data will be read.
NSLog(@"directly after beginSheetForDirectory");
.....
- (void) openSheetDidEnd:(NSOpenPanel *)panel
returnCode:(int)returnCode contextInfo:(void *)contextInfo; {
NSLog(@"directly inside openSheetDidEnd");
if (NSOKButton == returnCode)
NSLog(@"chosen sheet %@", [[panel filenames] objectAtIndex:0]);
else
NSLog(@"sheet cancelled");
}
This line:
NSString *filePath = [[panel filenames] objectAtIndex:0];
should be in the openSheetDidEnd:(NSOpenPanel *)panel... method.
