Got the following xcode: http://stackoverflow.com/questions/8482678/case-in-protected-switch But when i try to put something in case 1 (or empty) it's giving me an error? Weird problem because i dont know what a protected switch is and how i should fix it. Does anyone has a solution or clue to fix this? Weird.. - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UIViewController *controller; switch(indexPath.row) { case 0: NSLog(@"0"); //create instance of EKEventStore EKEventStore *eventStore = [[EKEventStore alloc] init]; //creating instance of EKEvent EKEvent *event = [EKEvent eventWithEventStore:eventStore]; //setting the appropriate properties of the new event event.title = @"Woow"; //event.startDate = [[NSDate alloc] init]; NSDateComponents *myDate2 = [[NSDateComponents alloc] init]; [myDate2 setDay:13]; [myDate2 setMonth:12]; [myDate2 setYear:2011]; [myDate2 setHour:00]; [myDate2 setMinute:34]; event.startDate = [[NSCalendar currentCalendar] dateFromComponents:myDate2]; event.endDate = [[NSDate alloc] initWithTimeInterval:3600 sinceDate:event.startDate]; event.location = @"game2"; event.notes = @" game"; event.alarms = [NSArray arrayWithObject:[EKAlarm alarmWithAbsoluteDate:event.startDate]]; [event setCalendar:[eventStore defaultCalendarForNewEvents]]; NSError *error; [eventStore saveEvent:event span:EKSpanThisEvent error:&error]; break; case 1: NSLog(@"1"); break; } { self.EKController.title = [self.EKList objectAtIndex:[indexPath row]]; } } @end But an error

In C++ you can declare protected scope variables pretty much anywhere (and declaring them close to first use is obviously a good thing) but the following still won't work: switch (val) { case VAL: // This won't work int newVal = 42; break; case ANOTHER_VAL: ... break; } The above gives me the following error (MSC): initialization of 'newVal' is skipped by 'case' label This seems to be a limitation in other languages too.

This means the compiler will interpret this as a jump directly to the label. In C++, the problem here is one of scope. Your curly brackets define the scope as everything inside the 'switch' statement. This means that you are left with a scope where a jump will be performed further into the code skipping the initialization. The correct way to handle this is to define a scope specific to that case statement and define your variable within it. switch (val) { case VAL: { // This will work int newVal = 42; break; } case ANOTHER_VAL: ... break; } share|improve this answer edited Sep 12 '14 at 4:35 M.M 71.9k662131 answered Sep 18 '08 at 13:17 Thomas 11k52429 75 Relative to opening a new scope - favor readability and consistency in the code.
