The Radio button And check box created based local json file,I designed both button dynamically on screen.I developed all code on iOS Swift Language.
class ViewController: UIViewController,UITextFieldDelegate
{
var btnRect:CGRect!=CGRect()
var ItemArray : NSMutableArray! = NSMutableArray()
var addArray : NSMutableArray! = NSMutableArray()
var itemDic: NSDictionary!=NSDictionary()
var radioButton:RadioButton!
var checkbox:UICheckbox!
var Scrollview:UIScrollView=UIScrollView()
override func viewDidLoad()
{
super.viewDidLoad()
//MARK: - Now calling the method get from local json file
self.navigationController?.navigationBar.tintColor=UIColor.greenColor()
readDataFromFile()
self.title="Looking for Catering Services"
self.Scrollview.frame=CGRectMake(0, 66, UIScreen.mainScreen().bounds.size.width, UIScreen.mainScreen().bounds.size.height-66)
Scrollview.backgroundColor=UIColor.clearColor()
self.view.addSubview(self.Scrollview)
self.ItemArray=self.itemDic.valueForKey("post") as NSMutableArray
self.automaticallyAdjustsScrollViewInsets=false
//MARK: - Now create the RadioButton and Checkbox
for var i = 0; i < self.ItemArray.count; i++
{
var dictionaryval=self.ItemArray.objectAtIndex(i) as NSDictionary
// println(btnRect.origin.y)
var lab:UILabel!=UILabel()
// println(dictionaryval)
lab.frame=CGRectMake(0, btnRect.origin.y, self.view.bounds.size.width, 50)
// println(dictionaryval)
lab.tag=i
lab.text=dictionaryval.valueForKey("Keyname") as? String
lab.lineBreakMode = NSLineBreakMode.ByWordWrapping
lab.numberOfLines = 0
self.Scrollview.addSubview(lab)
var checkType=dictionaryval.valueForKey("Type") as? String
btnRect = CGRectMake(20, lab.frame.size.height+btnRect.origin.y, 25, 25);
if((dictionaryval.valueForKey("Type") as NSString).isEqualToString("Radio"))
{
var QAnsIdArray:NSArray=NSArray()
QAnsIdArray=dictionaryval.valueForKey("information") as NSArray
var groupid = String(i)
for var z=0;z<QAnsIdArray.count;z++
{
//radio button assign to groupId and index
radioButton=RadioButton(groupId: groupid, index: UInt(z))
radioButton.tag=z
radioButton.frame = btnRect;
var Answer=QAnsIdArray.objectAtIndex(z) as String
if((Answer as NSString).isEqualToString("Other"))
{
}
else
{
var Answerlab:UILabel!=UILabel()
Answerlab.frame=CGRectMake(59, btnRect.origin.y, self.view.bounds.size.width, 25)
Answerlab.lineBreakMode=NSLineBreakMode.ByWordWrapping
Answerlab.numberOfLines=0
Answerlab.text=Answer
Scrollview.addSubview(Answerlab)
}
Scrollview.addSubview(radioButton)
btnRect.origin.y+=40;
RadioButton.addObserverForGroupId(groupid, observer: self)
}
}
else
{
var QAnsIdArray:NSArray=NSArray()
QAnsIdArray=dictionaryval.valueForKey("information") as NSArray
for var z=0;z<QAnsIdArray.count;z++
{
var Answer=QAnsIdArray.objectAtIndex(z) as String
checkbox=UICheckbox()
checkbox.frame=btnRect
checkbox.backgroundColor=UIColor.clearColor()
checkbox.addTarget(self, action:"oncheckButtonValueChanged:", forControlEvents: UIControlEvents.TouchUpInside)
checkbox.checked=false
checkbox.disabled=false
if((Answer as NSString).isEqualToString("Other"))
{
var Othertxt:UITextField = UITextField(frame: CGRectMake(55, btnRect.origin.y, 100, 25))
Othertxt.tag=z
checkbox.tag=z
Othertxt.placeholder="Other"
Othertxt.layer.borderColor=UIColor.grayColor().CGColor
Othertxt.layer.borderWidth=1.0
Othertxt.delegate=self
Othertxt.resignFirstResponder()
Scrollview.addSubview(Othertxt)
checkbox.accessibilityHint=Answer
}
else
{
checkbox.text=Answer
checkbox.tag=z
checkbox.accessibilityHint=Answer
}
checkbox.contentHorizontalAlignment=UIControlContentHorizontalAlignment.Left
btnRect.origin.y+=40
Scrollview.addSubview(checkbox)
}
}
Scrollview.contentSize=CGSizeMake(self.view.bounds.size.width, lab.bounds.size.height+btnRect.origin.y)
}
// Do any additional setup after loading the view.
}
override func didReceiveMemoryWarning()
{
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func textFieldShouldReturn(textField: UITextField) -> Bool
{
textField.resignFirstResponder()
return true
}
//MARK: - Load the json from local Food.Json file
func readDataFromFile()
{
var url:NSURL!
url=NSBundle.mainBundle().URLForResource("Food", withExtension: "json")
var request = NSURLRequest(URL: url, cachePolicy: NSURLRequestCachePolicy.ReloadIgnoringLocalCacheData, timeoutInterval: 5)
var response : NSURLResponse?
var error : NSError?
var data:NSData!
data = NSURLConnection.sendSynchronousRequest(request, returningResponse: &response, error: &error)
//MARK: -Now create a NSDictionary from the JSON data
self.itemDic = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: &error) as NSDictionary
}
//MARK: - radioButton Selected At Index
func radioButtonSelectedAtIndex(index :Int ,inGroup:NSString)
{
println(index)
println(inGroup)
}
//MARK: - On Check Box Selected At Index
func oncheckButtonValueChanged(sender: UICheckbox)
{
var variable=sender.accessibilityHint
println(variable)
println(sender.tag)
}
