UISegmentedControl in Mail app

How do I get a UISegmentedControl that is like the one开发者_Go百科 in the Mail App, so that it is the same colour as UIToolbar buttons (as if both segments were in the selected state).

I want to use the segmented control for exactly the same purpose as Mail.

(on the iPad, so a grey not blue color)

This is code from Apple Sample codes... NavBar and both the images used in the code.. you shoud be able to get exact same view as mail App.

// "Segmented" control to the right
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
                                            [NSArray arrayWithObjects:
                                                [UIImage imageNamed:@"up.png"],
                                                [UIImage imageNamed:@"down.png"],
                                             nil]];
[segmentedControl addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
segmentedControl.frame = CGRectMake(0, 0, 90, 30);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.momentary = YES;

defaultTintColor = [segmentedControl.tintColor retain];    // keep track of this for later

UIBarButtonItem *segmentBarItem = [[UIBarButtonItem alloc] initWithCustomView:segmentedControl];
[segmentedControl release];

self.navigationItem.rightBarButtonItem = segmentBarItem;
[segmentBarItem release];

You seek the tintColor property!

When you use a UISegmentedControl you can change its tint color to any color you can dream up. So, if you added the UISegmentedControl in Interface Builder then you would style it in your - (void)viewWillAppear:(BOOL)animated method as such (assuming you had it hooked up to a @synthesized ivar:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    // Set the tintColor to match the navigation bar
    self.mySegmentedControl.tintColor = [UIColor colorWithRed:.94 green:.94 blue:.94 alpha:1];

    ... do whatever else in your viewWillAppear ...
}

Now obviously you will want to play with the red, green, blue, and alpha's that I've put in the sample code above, but you can literally tint the UISegmentedController any color you would like (or make it as transparent as you would like), so it's just a matter of finding the RGBA values that look perfect to you.

Remember that per Apple's docs that the default value of this property is nil (no color). UISegmentedControl uses this property only if the style of the segmented control is UISegmentedControlStyleBar.

Good luck!

I dont know exactly what you mean.. but i believe the "UISegmentedControlStyleBar" as segmentedControlStyle could it be.

segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar

You can set this property in the IB too! (It's the property called "style")

The style I'm looking for is undocumented: it is style 4. It looks like he up/down control here: http://media.mobilemeandering.com/wp-content/uploads/2010/04/ipad-mail-message-2.png (not my image btw)

It basically makes all segments look selected, it's intended for momentary pushes, and is effectively multiple tool bar buttons pushed up together. So it can't be set in IB but must be set in code or manually in the nib/xib file, by opening the nib as a text file.

I'm not sure I exactly understand what you're trying to do, but I'll give it a shot.

The solution is not obvious, you need to use a UISearchDisplayController in order to get a matching UISearchBar and UISegmentedControl.

See the TableSearch sample code for an example.
