What is causing this: Cannot jump from switch statement to this case label [duplicate]

Question

This is a switch statement that I am getting errors on:

        switch (transaction.transactionState) {          case SKPaymentTransactionStatePurchasing:              // show wait view here             statusLabel.text = @"Processing...";             break;          case SKPaymentTransactionStatePurchased:              [[SKPaymentQueue defaultQueue] finishTransaction:transaction];              // remove wait view and unlock iClooud Syncing             statusLabel.text = @"Done!";              NSError *error = nil;             [SFHFKeychainUtils storeUsername:@"IAPNoob01" andPassword:@"whatever" forServiceName: kStoredData updateExisting:YES error:&error];              // apply purchase action  - hide lock overlay and             [oStockLock setBackgroundImage:nil forState:UIControlStateNormal];              // do other thing to enable the features              break;          case SKPaymentTransactionStateRestored:              [[SKPaymentQueue defaultQueue] finishTransaction:transaction];              // remove wait view here             statusLabel.text = @"";             break;          case SKPaymentTransactionStateFailed:              if (transaction.error.code != SKErrorPaymentCancelled) {                 NSLog(@"Error payment cancelled");             }             [[SKPaymentQueue defaultQueue] finishTransaction:transaction];             // remove wait view here             statusLabel.text = @"Purchase Error!";             break;          default:             break;     } 

The last two cases, plus the default, are giving me the following error:

Cannot jump from switch statement to this case label

I have used the switch statement many, many times; this is the first time I have seen this. The code has been copied from a tutorial (here), which I am trying to adapt for my app. Would appreciate the help on this one. SD

C is not Swift. You'll be happier if you structure your switch statements using curly braces round all of the cases interiors, like this:

switch (tag) {     case 1: { // curly braces         // ...         break;     }     case 2: {  // curly braces         // ...         break;     }     case 3: {  // curly braces         // ...         break;     } } 

The extra level of curly braces allows you to do things you can't do otherwise.
