Did you really want to create an NSArray (non-mutable) and then pass it off as
an NSMutableArray? Since you mentioned ARC, I'm surprised the compiler didn't
flag the type mismatch. You might have better luck creating the NSMutableArray
that your completion routine seems to be expecting:
NSMutableArray *someInfo = [NSMutableArray arrayWithObjects:@"made" ,
@"it", @"across",. nil];
[holdAlert beginSheetModalForWindow:[self window] modalDelegate:self
didEndSelector:@selector(
alertDidEnd:returnCode:contextInfo: ) contextInfo:someInfo;
-(void)alertDidEnd:(NSAlert *)alert returnCode:(int)returnCode
contextInfo:(void *)contextInfo
{
NSMutableArray *holdArray = (NSMutableArray*)contextInfo;
...
}
Or, if the array doesn't really need to be mutable, use NSArray throughout. The
only reason to make it mutable would be so the completion handler could use it
to pass information back, but of course it has the delegate itself for that.
Or, use a block. That might be simpler
still._______________________________________________
