9 Notes November 2021
1. Cannot assign to property: 'parameters' is get-only property
#second method
If you use textfield into tableView you can use this, it scroll textField in tableViewCell
to fixing that error add "set" after {get}
//Before
var parameters: [String: Any]? { get }
//After
var parameters: [String: Any]? { get set }2. When keyboard appear textfield scroll up
when the keyboard covers the display of the textfield when it appears, here are two ways you can do
#First method
If textfield is in UIView, you can use this method

3. Failed install "zsh: command not found: fastlane"
In condition you want to run fastline command like "$fastlane match development" but you get this info "zsh: command not found: fastlane"
solution is follw this step
$xcode-select --install
$sudo gem install fastlane
In condition you want to run fastline command like "$fastlane match development" but you get this info "zsh: command not found: fastlane"

$sudo gem install fastlane
after install complete try to install this again
$fastlane match development
success like this image

| image: fastlane success |
4. Error code "awakeFromNib"
when you use func like this in the UIView file if you call data into this func

you can get this error " cannot assing of type ...
 |
| author image |
to fixing that you can remove class from that function like this

8. Set background color follow the UILabel character
When I need to set background follow the uilabel this I found in stackoverflow can help mu code
and my code look like this
label.text = " MORE LIVES "
guard let value = label.text else {return}
let attributeString = NSMutableAttributedString(string: value)
var startIndex = 0
attributeString.addAttribute(NSAttributedString.Key.backgroundColor, value: UIColor.red, range: NSRange(location: startIndex, length: value.count))
startIndex = startIndex + value.count + 1
label.attributedText = attributeString
this my example from stackoverflow, thanks for answer
label.text = """
GET
MORE LIVES
"""
label.numberOfLines = 0
let attributeString = NSMutableAttributedString(string: label.text!)
let labelText = label.text!
var lines: [String] = []
labelText.enumerateLines { line, _ in
lines.append(line)
}
print(lines)//lines in your text
var startIndex = 0
for value in lines {
//Apply background color to lines
attributeString.addAttribute(NSAttributedString.Key.backgroundColor, value: UIColor.red, range: NSRange(location: startIndex, length: value.count))
startIndex = startIndex + value.count + 1
//startIndex will locate new line's first index
}
//Assign attributedText to your label
label.attributedText = attributeString9. Marging array dictionary to single dictionary
I found error post api when I get data array [[String: Any]] and I want to change to single dictionary
like this [String: Any], and this solve my problem :)
this example use model to single [String: Any] for post API parameters
like this [String: Any], and this solve my problem :)
this example use model to single [String: Any] for post API parameters
struct ParamFormPersonal {
var key: String
var label: String
var value: String
func parameters() -> [String: Any] {
return [
key: value
]
}
}
var dataArray = [ParamFormPersonal]()
// append with model
dataArray.append(ParamFormPersonal(key: "key1", label: "hahah", value: "one"))
dataArray.append(ParamFormPersonal(key: "key2", label: "hahah", value: "two"))
dataArray.append(ParamFormPersonal(key: "key3", label: "hahah", value: "three"))
// this how to marging array dictionary
var dataIs = [String: Any]()
dataArray.forEach { data in
dataIs = dataIs.merging([data.key : data.value]) { (current, _) in current }
}
print(dataIs) //["key3": "three", "key2": "two", "key1": "one"] see thin link can help you :)
