For my app I need to know the type of location that I got. For example, when you go to the maps app and you click on a location it tells if it is a hotel, restaurant, retailer, pharmacy, etc. I wanted to know how to get this from a CLPlacemark object that I got earlier.

I have a CLPlacemark and need to know if it is a restaurant, hotel, pharmacy, etc. In the maps app, when you click on a location, it shows you the type of place that it is (Restaurant, retailer, transportation, etc). Is there any way to do this?
When I get the location of a user it, in most cases, return the name of a plaza and I need each individual store inside of it. Is there any way to get that?
I have 10 programmatically buttons create, they all work except for the first.for image in 1...10 {
let imageName = String("image\(String(image)).png")
let imageToDisplay = UIImage(named: imageName)
let catagoryButton = UIButton(type: UIButton.ButtonType.custom) as UIButton
catagoryButton.setBackgroundImage(imageToDisplay, for: .normal)
let xCoor = 20 + 60 * CGFloat(image - 1)
contentWidth += 60
catagoryButton.frame = CGRect(x: xCoor, y: 10, width: 40, height: 40)
catagoryButton.addTarget(self, action: #selector(buttonAction), for: .touchUpInside)
catagoryButton.tag = image
catagoryScrollView.addSubview(catagoryButton)
print("This Buttons tag is \(catagoryButton.tag)")
}
catagoryScrollView.contentSize = CGSize(width: contentWidth + 20, height: 60)
The button action works fine for all of the other buttons, but just incase it just checks for the sender.tag and does a different action depending on the sender.
@objc func buttonAction(sender: UIButton!) {
print("button number \(sender.tag)")
var showThisArray = [CreditCard]()
var showThisArrayOfValues = [Double]()
if sender.tag == 1 {
showThisArray = restaurantCards
showThisArrayOfValues = restaurantCardsValues
cardReward = "Restaurants"
}
else if sender.tag == 2 {
showThisArray = gasCards
showThisArrayOfValues = gasCardsValues
cardReward = "Gas Stations"
}
else if sender.tag == 3 {
showThisArray = hotelCards
showThisArrayOfValues = hotelCardsValues
cardReward = "Hotels"
}
else if sender.tag == 4 {
showThisArray = groceryCards
showThisArrayOfValues = groceryCardsValues
cardReward = "Grocery Stores"
}
else if sender.tag == 5 {
showThisArray = transitCards
showThisArrayOfValues = transitCardsValues
cardReward = "Transit Station"
}
else if sender.tag == 6 {
showThisArray = wholesaleCards
showThisArrayOfValues = wholesaleCardsValues
cardReward = "Wholesalers"
}
else if sender.tag == 7 {
showThisArray = drugStoreCards
showThisArrayOfValues = drugStoreCardsValues
cardReward = "Drug Stores"
}
else if sender.tag == 8 {
showThisArray = entertainmentCards
showThisArrayOfValues = entertainmentCardsValues
cardReward = "Entertainment Locations"
}
else if sender.tag == 9 {
showThisArray = supplyCards
showThisArrayOfValues = supplyCardsValues
cardReward = "Supply Stores"
}
else if sender.tag == 10 {
showThisArray = departmentCards
showThisArrayOfValues = departmentCardsValues
cardReward = "Department Stores"
}
else if sender.tag == 11 {
showThisArray = otherCards
showThisArrayOfValues = otherCardValues
cardReward = "Other Categories"
}
// More code that is not important
}
I cannot figure out the root of the problem and I need all of the buttons to work
I am trying to get json data from a site that I created and no matter what I do it says...
"The data couldn’t be read because it isn’t in the correct format"
The JSON is...
{
	"creditCards": [
		{
		"issuer": "american express",
		"name": "gold card",
		"numericCode": "3717",
		"image": "",
		"rewards": [
		{
				"value": "4.0",
				"reward": "restaurants"
		},
		{
				"value": "4.0",
				"reward": "grocery stores"
		}
		]
		},
		{ "issuer": "american express",
		"name": "cash magnet",
		"numericCode": "",
		"image": "",
		"rewards": [
		{
				"value": "1.5",
				"reward": "all"
		}
		]
		},
		
		{ "issuer": "american express",
		"name": "green card",
		"numericCode": "",
		"image": "",
		"rewards": [
		{
				"value": "3.0",
				"reward": "restaurants"
		},
		{
				"value": "3.0",
				"reward": "transit"
		}
		]
		},
		
		{ "issuer": "american express",
		"name": "blue cash everyday",
		"numericCode": "375987",
		"image": "",
		"rewards": [
		{
				"value": "3.0",
				"reward": "grocery stores"
		},
		{
				"value": "2.0",
				"reward": "gas stations"
		}
/* More credit cards that have the same JSON syntax */
]
}
And my code for getting the JSON is...
guard let url = URL(string: "my_url_that_works") else {
print("URL Failed")
return
}
print("url (\(url)) passed!")
var request = URLRequest(url: url)
request.httpMethod = "GET"
URLSession.shared.dataTask(with: request) { (data, response, error) in
if let err = error {
print(err.localizedDescription)
return
}
print("data: \(data!)")
print("response: \(response!)")
do {
print("Time to get JSON")
guard let json = try JSONSerialization.jsonObject(with: data!, options: []) as? [NSDictionary] else {
print("error: \(error?.localizedDescription)")
return
}
print(json["creditCards"]) /* This prints the error above */
} catch {
print(error.localizedDescription)
}
}.resume()
I have done a lot of research into how to solve this and none of the things I do seem to work. I would really appreciate some yelp.
Hi! I am trying to create a DropDownMenu class, but when I try to call addTarget to a UIButton this error comes up...
'unrecognized selector sent to instance 0x7fd167f06120' terminating with uncaught exception of type NSException'
I have been looking for the answer for hours now, and even on Stack Overflow, no one seems to have the answer. Any help is appreciated!
Here is the code for my DropDownMenu class...class DropDownMenu: UIView {
var main: UIButton! = UIButton(frame: CGRect(x: 0, y: 0, width: 46, height: 30))
var view: UIView!
	var buttonTitles: [String]! = [""]
var titleColor: UIColor! = UIColor.black
var font: UIFont! = UIFont.systemFont(ofSize: 18)
var buttonsBorderWidth: CGFloat! = 0
var buttonsBorderColor: UIColor? = UIColor.white
var buttonsCornerRadius: CGFloat! = 0
var color: UIColor! = UIColor.clear
var buttonsImageEdgeInsets: UIEdgeInsets? = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
var images: [UIImage]? = nil
var target: UIViewController!
private var currentSelected: String? = nil
private var optionsStack = UIStackView()
init(main: UIButton) {
self.main = main
super.init(frame: CGRect())
}
func createDropDownMenu() {
main.addTarget(target, action: #selector(DropDownMenu.openDropdown(:)), for: .touchUpInside)
print("Button Target?: \(main.allTargets), self.target: \(String(describing: target))")
let mainFrame = main.frame
optionsStack.frame = CGRect(x: mainFrame.minX, y: mainFrame.maxY, width: mainFrame.width, height: CGFloat(buttonTitles.count) * mainFrame.height)
optionsStack.axis = .vertical
view.addSubview(optionsStack)
var y: CGFloat! = 0
for title in buttonTitles {
let button = UIButton(frame: CGRect(x: 0, y: y, width: mainFrame.width, height: mainFrame.height))
button.setTitle(title, for: .normal)
button.setTitleColor(titleColor, for: .normal)
button.backgroundColor = color
button.titleLabel?.font = font
button.addTarget(target, action: #selector(DropDownMenu.onclick), for: .touchUpInside)
y += mainFrame.height
optionsStack.addArrangedSubview(button)
}
for button in optionsStack.arrangedSubviews {
button.isHidden = true
button.alpha = 0
}
}
@objc private func openDropdown( sender: UIButton) {
print("sender: \(String(describing: sender))")
optionsStack.arrangedSubviews.forEach { (button) in
UIView.animate(withDuration: 0.7) {
button.isHidden = !button.isHidden
button.alpha = button.alpha == 0 ? 1 : 0
self.view.layoutIfNeeded()
}
}
}
@objc private func onclick(_ sender: UIButton) {
let title = sender.titleLabel!.text
print(title as Any)
main.setTitle(title, for: .normal)
optionsStack.arrangedSubviews.forEach { (button) in
UIView.animate(withDuration: 0.7) {
button.isHidden = true
button.alpha = 0
}
}
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
Here is the code for the creation of the object in ViewContorller...
let main = UIButton(frame: CGRect(x: 50, y: 300, width: 80, height: 30))
main.layer.borderWidth = 1
main.setTitle("Grade", for: .normal)
main.titleLabel?.font = UIFont.boldSystemFont(ofSize: 20)
main.setTitleColor(UIColor.black, for: .normal)
let gradeDP = DropDownMenu(main: main)
gradeDP.buttonTitles = ["Title 1", "Title 2", "Title 3"]
gradeDP.color = UIColor.gray
gradeDP.target = self
gradeDP.titleColor = UIColor.white
gradeDP.view = infoBox
This is all of my code...
