How to set image to the UISegmentedControl in iPhone?

问题

I am new to iPhone development. I have created UISegmentedControl having 2 segments. I want to display images for each segment instead of title. Here is my code

NSArray *itemArray = [NSArray arrayWithObjects: @"segment1", @"segment2", nil];
UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:itemArray];
segmentedControl.frame = CGRectMake(5,100,300,40);
segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.selectedSegmentIndex = 1;
[self.view addSubview:segmentedControl];
[segmentedControl release]; 

But instead of displaying the title ,segment1 and segment2 it should be replaced with the images I have.

回答1:

It is almost exactly what you had, just pass an array of UIImages instead of NSStrings.

NSArray *itemArray = [NSArray arrayWithObjects:
    [UIImage imageNamed:@"segment1.png"],
    [UIImage imageNamed:@"segment2.png"],
    nil];

回答2:

If you want to change the image during runtime, use the following method:

- (void)setImage:(UIImage *)image forSegmentAtIndex:(NSUInteger)segment

e.g.:

[segmentedControl setImage:[UIImage imageNamed:@"segment1.png"] forSegmentAtIndex:0];

It's simple to do it with Interface Builder (Attributes Inspector tab).

Also you can set one segment with image and the other one with text.

For interface builder user, set "render as" as "original image" rather than default. In my case, it will show after running. It may work. @jcpennypincher

In xcode 4.6.3 there is an option in interface builder to add an image to the segment controls.
