iOS: Dynamic Creation of UISegmentedControl within UIView - ios

Question

I am wanting to create a custom UIView class that will show a dynamic number of UISegmentedControl objects depending on some input. For example, if a client has 5 products in their cart, the UIView should generate 5 UISegmentedControl objects that I will then link with each item.
The problem I am having is getting this to work in a UIView. Here is what I have done so far. I am successfully able to create a UISegmentedControl object and display it programmatically within my main UIViewController. I don't get any display when adding it to my UIView class. Here is the implementation code for the UIView class:
#import "ajdSegmentView.h"
#implementation ajdSegmentView
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
// Initialization code
NSArray *itemArray = [NSArray arrayWithObjects:#"Yes", #"No", nil];
UISegmentedControl *button = [[UISegmentedControl alloc] initWithItems:itemArray];
button.frame = CGRectMake(35,44, 120,44);
button.segmentedControlStyle = UISegmentedControlStylePlain;
button.selectedSegmentIndex = 1;
[self addSubview:button];
}
return self;
}
#end
I created a new UIView object via Storyboard and placed it inside the UIViewController scene. I made sure to set the class from the generic UIView class to my new custom class. I added and outlet for the UIView in my UIViewController class. Here is the code inside the implementation of UIViewController:
#import "ajdViewController.h"
#interface ajdViewController ()
#end
#implementation ajdViewController
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
self.segmentView = [[ajdSegmentView alloc] init];
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#end
That's all I have tried. I have been searching through a lot of pages and trying to implement this without asking here, but I seem to be looking in the wrong places.

Answer 1

First you need to check ajdSegmentView is UIVIew or UIViewController. It is fine if it is UIView. If it is type of UIViewController then you need to add this line while adding Segment.
[self.view addSubview:button];
In place of:
[self addSubview:button];
And One more thing You forget to add this View to your main after allocating so You can declare like this:
objajdSegmentView = [[ajdSegmentView alloc] init];
[self.view addSubview:objajdSegmentView.view];
I have just added this thing. i got result like this way.
Hope this will work for you.

You're initializing your custom view using the init method, but your initialization for ajdSegmentView is in your initWithFrame: method (which in your case is not getting called).
So replace:
self.segmentView = [[ajdSegmentView alloc] init];
with:
// Change the frame to what you want
self.segmentView = [[ajdSegmentView alloc] initWithFrame:CGRectMake(0,0,100,40)];
Also don't forget to add your view to the view controller's view also.
[self.view addSubview:self.segmentView];
Unless this view is being created with interface builder, in which case you will need to override initWithCoder: in your ajdSegmentView class.
I'm not familiar with Storyboard though, so maybe I'm missing something, but in a standard scenario what I said above will solve your problem.
