2. How to configure test target in Xcode
this example to configure target like call function in class
# Testing Pods
def test_pods
pod 'Quick'
pod 'Nimble'
end
and call in target like this
target 'QuickNimbleUnitTestingTests' do
inherit! :search_paths
# Pods for testing
test_pods
end
- This full file in "Podfile"
# Uncomment the next line to define a global platform for your project
platform :ios, '9.0'
# Testing Pods
def test_pods
pod 'Quick'
pod 'Nimble'
end
target 'QuickNimbleUnitTesting' do
# Comment the next line if you don't want to use dynamic frameworks
use_frameworks!
# Pods for QuickNimbleUnitTesting
target 'QuickNimbleUnitTestingTests' do
inherit! :search_paths
# Pods for testing
test_pods
end
target 'QuickNimbleUnitTestingUITests' do
inherit! :search_paths
# Pods for testing
end
end
3. View Background color opacity programmatically
view.backgroundColor = UIColor.black.withAlphaComponent(0.75)
view.isOpaque = false
4. How to print type data or nsdata
If you have problem to check you data type you can use this
let data: Data?
let string1 = String(data: data!, encoding: String.Encoding.utf8)
print(string1)
Or use debug area
(lldb) po String(data: data!, encoding: String.Encoding.utf8)
▿ Optional<String>
- some : "[{\"key\":\"language.preference\",\"value\":\"en-ID\"},{\"key\":\"limit.postlogin.nopin.amount\",\"value\":\"500000\"},{\"key\":\"prelogin.check.balance\",\"value\":\"true\"}]"
5. Ascending and Descending
func assendingAndDesending() {
let sortString: [String] = ["baak", "Aaak", "Cadak", "dasak"]
// Sort Ascending
print(sortString.sorted(by: { $0.uppercased() < $1.uppercased() }), "Sort Ascending ?")
let asd = sortString.sorted(by: >)
print(asd)
/*
["Aaak", "baak", "Cadak", "dasak"] Sort Ascending ?
A -> Z
*/
// Sort Descending
print(sortString.sorted(by: { $0.uppercased() > $1.uppercased() }), "Sort Descending ?")
/*
["dasak", "Cadak", "baak", "Aaak"] Sort Descending ?
Z -> A
*/
}
6. Bug UI in IOS 11
In my project found UI bug IOS 11 but in IOS 13.5 is good,
after checking code and finally found that solution
Condition from viewController add subview as (UIView)
In my project found UI bug IOS 11 but in IOS 13.5 is good,
after checking code and finally found that solution
Condition from viewController add subview as (UIView)
override func viewDidLoad() {
super.viewDidLoad()
let newSubview = SubView()
UIView.transition(with: view, duration: 1, options: .transitionCrossDissolve, animations: { [weak self] in
guard let `self` = self else { return }
self.view.addSubview(newSubview.backgroundView)
}, completion: nil)
}
7. Put "others" in last array use "sort" and "map"
import UIKit
class SortMapViewController: UIViewController {
override func viewDidLoad() {
super.viewDidLoad()
// put others in last array use sort and map
let array: [String] = ["Adam", "payment", "Money", "Bank", "just", "Circle", "Doom", "Kelints", "others"]
var newArray = [String]()
let categories = array.filter { $0 != "others" }
let models: [String] = categories.map {
let category = $0.lowercased()
return category
}
let sorted = models.sorted(by: { (category0, category1) -> Bool in
category0.lowercased() < category1.lowercased()
})
newArray.append(contentsOf: sorted)
array.forEach { trans in
if trans == "others" {
let category = trans.lowercased()
newArray.append(category)
}
}
print(newArray) //["adam", "bank", "circle", "doom", "just", "kelints", "money", "payment", "others"]
}
}
8. Use SKOverlay (Availabilly in MacOs 11+)
