iPhone: Error and error handling confusion in comparison.
- by Mr. McPepperNuts
NSArray *results = [managedObjectContext executeFetchRequest:request error:&error];
if(results == nil){
NSLog(@"No results found");
searchObj = nil;
}else{
if ([[[results objectAtIndex:0] name] caseInsensitiveCompare:passdTextToSearchFor] == 0) {
NSLog(@"results %@", [[results objectAtIndex:0] name]);
searchObj = [results objectAtIndex:0];
}else {
NSLog(@"No results found");
searchObj = nil;
}
}
The code above compares data a user enters to data pulled from a database. If I enter data which is in the database; it works. But if I enter complete gibberish it returns the error below instead of "No results found."
*** WebKit discarded an uncaught exception in the webView:shouldInsertText:replacingDOMRange:givenAction: delegate: <NSRangeException> *** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)
The results array being null should be accounted for during the checks in the above code, no?
