Question

I have a UISegmentedControl and I want to change the selected segment programmatically by a value on another view controller. I attempted to use an NSString but it is not working. Any ideas?

Answer 1

just use NSUserDefaults.

save your string in NSUserDefaults in another view controller like

 [[NSUserDefaults standardUserDefaults] setValue:@"first" forKey:@"uniquekey"];

then make if condition in a viewcontroller which has UISegmentedcontroll like

first get nsstring from nsuserdefaults like

NSString *getstr = [[NSUserDefaults standardUserDefaults] objectForKey:@"uniquekey"];

then make if condition

if([getstr isEqualToString:@"first"]
{
    segment first
}
else
{
    segment second
}
