Selected segment of UISegmentedControl

I开发者_高级运维 am using an UISegmentedControl with two sections: the first is Don't Remember Password and the second is Remember Password. If they select Remember Password, I use NSUserDefaults to remember this. On startup, how do I make Remember Password selected if NSUserDefaults is YES?

if ([[NSUserDefaults standardUserDefaults] setBool:YES forKey:@"Remember password"] == YES)
{

    //Make the second segment (segment 1 as it would be called, since first is segment 0) selected
}

It is as simple as setting selectedSegmentIndex inside of viewDidLoad to ensure that the segment is not nil.

-(void)viewDidLoad
{
    [super viewDidLoad];

    if([[NSUserDefaults standardUserDefaults] boolForKey:@"Remember Password"])
    {
        segment.selectedSegmentIndex = 1;
    }
    else
    {
        segment.selectedSegmentIndex = 0;
    }
}

Also why not use a UISwitch and set the on value directly to the stored value?

When dealing with a boolean setting I would recommend using a UISwitch instead of a segmented control. The switch would either activate or de-activate the remember password.

The way you set the value is correct, to get the value back you use:

[[NSUserDefaults standardUserDefaults] boolForKey:@"Remember password"];

So if you use a UISwitch you could do:

switch.on = [[NSUserDefaults standardUserDefaults] boolForKey:@"Remember password"];

If you do want to use a UISegmentedControl it is a bit longer but just as simple:

if ([[NSUserDefaults standardUserDefaults] boolForKey:@"Remember password"]) {
        segmentedControl.selectedSegmentIndex = 1;
    }
    else{
        segmentedControl.selectedSegmentIndex = 0;
    }

Just remember that a UISwitch makes more senese to the user when dealing with a boolean setting.

Update:

To set the value using a switch you simply do:

[[NSUserDefaults standardUserDefaults] setBool:switch.on forKey:@"Remember password"];

It is a lot simpler than using a UISegmentedControl.
