The NSAlert's buttons return an integer, depending on which button is clicked, so you should use an if end if condition check like this.
Code:
NSAlert *alert = [[NSAlert alloc] init];
[alert addButtonWithTitle:@"Delete"];
[alert addButtonWithTitle:@"Cancel"];
[alert setMessageText:@"Delete the record?"];
[alert setInformativeText:@"Deleted records cannot be restored."];
[alert setAlertStyle:NSWarningAlertStyle];
if ([alert runModal] == NSAlertFirstButtonReturn) {
// Delete button clicked.
} else {
// Cancel button clicked.
}
Or.
Code:
NSAlert *alert = [[NSAlert alloc] init];
[alert addButtonWithTitle:@"Yes"];
[alert addButtonWithTitle:@"No"];
[alert addButtonWithTitle:@"Cancel"];
[alert setMessageText:@"Answer this question?"];
[alert setAlertStyle:NSWarningAlertStyle];
NSInteger result = [alert runModal];
if ( result == NSAlertFirstButtonReturn ) {
// Yes button clicked
} else if ( result == NSAlertSecondButtonReturn ) {
// No button clicked
} else if ( result == NSAlertThirdButtonReturn ) {
// Cancel button clicked
}
If you use the class method.
+ (NSAlert *)alertWithMessageText
NSString *)messageTitle defaultButton
NSString *)defaultButtonTitle alternateButton
NSString *)alternateButtonTitle otherButton
NSString *)otherButtonTitle informativeTextWithFormat
NSString *)informativeText
To create your alert panel.
Then you can check the NSAlertDefaultReturn = 1, NSAlertAlternateReturn = 0, NSAlertOtherReturn = -1, or NSAlertErrorReturn = -2 to check for an error, in the same way as the above examples.
Hope this helps.
