all, this code does not throw errors now but the screen is blank. I am trying to create a simple calculator. user will input numbers into 3 separate UIText fields, push a button and a UILabel would give answer. I know i do not have labels yet. i first built a container to hold text fields but then my "CalculateTapped" could not see the textFields as variables.
Question. 1 why is my screen now black?
Question. 2. why could i not get CalculateTapped to read UIText fields from my lazy var "" view earlier?
If anyone has any input i would greatly appreciate it. trying to get away from storyboards.

I have created a Swift framework that creating a button programmatically, and the action of the button is showing a webView and close it, my framework works fine in Swift project but in Objective C it just create button but it is not taking action and does not show my webView,

and I have created a Objective-C and add the built framework in it and its .m file code is below :
#import "ViewController.h"
#import myFrameWork;
#import <myFrameWork/myFrameWork-Swift.h>
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
predictionButton *btn = [[predictionButton alloc] init];
[btn addButtonPredictWithView:self.view phone:#"XXXXXXX"
token:#"XXXXXXXXXXXXXXXXXXXXXXXXXXX"];
}
#end
Note: this framework works fine in Swift project
Here is working swift code:
import UIKit
import myFrameWork
import WebKit
class ViewController: UIViewController {
var button = predictionButton()
override func viewDidLoad() {
super.viewDidLoad()
button.addButtonPredict(view: self.view, phone: "XXXXXXXXXX", token: "XXXXXXXXXXXXXXXXXXXXXXXXX")
}
I created a UICollectionView named UserProfileController.
I created a UICollectionViewCell named UserProfilePhotoCell.
I created avplayer in UserProfilePhotoCell.
When you click on Avplayer the video starts.
When I click on the 1st AVPlayer on the cell,
The first, fifth, ninth cells play AVplayer.
How can I fix?

Just use this code for play video in the cell with expect index. It will help you a lot and for other also ,
class UserProfilePhotoCell: UICollectionViewCell {
#IBOutlet var viewForVideo: UIView!
#IBOutlet var btnPlayVideo: UIButton!
var blockVideoPlay : ((_ sender : UIButton)->())?
override func awakeFromNib() {
super.awakeFromNib()
removeSubLayerFromVideo()
self.setupMoviePlayer()
}
#IBAction func btnPlayVideoCLK(_ sender: UIButton) {
if blockVideoPlay != nil {
blockVideoPlay!(sender)
}
}
func removeSubLayerFromVideo() {
if let layerArray = viewForVideo.layer.sublayers, layerArray.isEmpty {
for layer in layerArray {
if layer.name == "\(viewForVideo.tag)" {
layer.removeFromSuperlayer()
}
}
}
}
func setupMoviePlayer(){
self.avPlayer = AVPlayer.init(playerItem: self.videoPlayerItem)
avPlayerLayer = AVPlayerLayer(player: avPlayer)
avPlayerLayer?.videoGravity = AVLayerVideoGravity.resizeAspect
avPlayerLayer?.name = "\(viewForVideo.tag)"
avPlayer?.volume = 3
avPlayer?.actionAtItemEnd = .none
avPlayerLayer?.frame = CGRect(x: 0, y: 0, width: UIScreen.width, height: UIScreen.height)
self.viewForVideo.backgroundColor = .clear
self.viewForVideo.layer.insertSublayer(avPlayerLayer!, at: 0)
// This notification is fired when the video ends, you can handle it in the method.
NotificationCenter.default.addObserver(self,
selector: #selector(self.playerItemDidReachEnd(notification:)),
name: NSNotification.Name.AVPlayerItemDidPlayToEndTime,
object: avPlayer?.currentItem)
}
func stopPlayback(){
if let player = self.avPlayer {
if player.isPlaying {
player.pause()
}
}
}
func startPlayback(){
self.avPlayer?.play()
}
// A notification is fired and seeker is sent to the beginning to loop the video again
#objc func playerItemDidReachEnd(notification: Notification) {
//let p: AVPlayerItem = notification.object as! AVPlayerItem
//p.seek(to: kCMTimeZero)
btnPlayVideo.isSelected = false
self.avPlayer?.currentItem?.seek(to: kCMTimeZero, completionHandler: { (success) in
if success {
self.avPlayer?.pause()
}
})
}
}
For View Controller use this code also you can post via var all data in the cell and from the cell, you can set URL path it works fine make sure when view Will Disappear you have to stop the player
class UserProfileController: UICollectionViewController, UICollectionViewDelegateFlowLayout {
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(true)
for cell in mediaListCollection.visibleCells {
if let cell = cell as? UserProfilePhotoCell {
cell.stopPlayback()
}
}
}
func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
var cell = collectionView.dequeueReusableCell(withReuseIdentifier: "cellId", for: indexPath) as! UserProfilePhotoCell
let url = URL(fileURLWithPath: path, isDirectory: true)
cell.videoPlayerItem = AVPlayerItem(url: url)
cell.viewForVideo.tag = indexPath.row+1
cell.blockVideoPlay = { (sender) -> Void in
sender.isSelected = !sender.isSelected
if sender.isSelected {
cell.startPlayback()
}
else {
cell.stopPlayback()
}
}
}
func collectionView(_ collectionView: UICollectionView, didEndDisplaying cell: UICollectionViewCell, forItemAt indexPath: IndexPath) {
if let cell = cell as? UserProfilePhotoCell {
cell.stopPlayback()
if cell.btnPlayVideo.isSelected {
cell.btnPlayVideo.isSelected = false
}
}
}
}
Also use this extension for check player is currently playing or not
extension AVPlayer {
var isPlaying: Bool {
return rate != 0 && error == nil
}
}
After upgrading the iOS 11 and swift 4(Xcode 9), I got lots of UI problem. :(
The most unsolvable problem is Navigation Problem. I put the Navigation Bar in UICollectionView Controller. Navigation bar height does not show properly and however I write the code.
I set navigation bar height "100". I write this code in ViewDidLoad().
if #available(iOS 11.0, *) {
print("IOS 11 Screen")
UINavigationBar.appearance().largeTitleTextAttributes = [
NSForegroundColorAttributeName: UIColor.white,
]
navigationItem.largeTitleDisplayMode = .never
let height: CGFloat = 100 //whatever height you want
let bounds = self.navigationController!.navigationBar.bounds
self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)
} else {
print("lower than IOS 11 Screen")
// Fallback on earlier versions
}
collectionview?.frame = CGRect(x: 0, y: 10, width: UIScreen.main.bounds.width, height: (UIScreen.main.bounds.height + 20)) <br>
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let height: CGFloat = 100 //whatever height you want
let bounds = self.navigationController!.navigationBar.bounds
self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)
}
override func viewWillAppear(_ animated: Bool) {
let height: CGFloat = 100 //whatever height you want
let bounds = self.navigationController!.navigationBar.bounds
self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)
}
However, I tried with this code. Nothing works for me.
I also tried to open the storyboard with source code view and I edit the height of Navigation bar. But, it also does not work.
Can anyone help me please? I have been trying to solve this problem since last two days.
Please check :
override func viewDidLoad() {
if #available(iOS 11.0, *) {
print("IOS 11 Screen")
UINavigationBar.appearance().largeTitleTextAttributes = [
NSForegroundColorAttributeName: UIColor.white,
]
self.navigationController?.navigationBar.prefersLargeTitles = true // added this line
navigationItem.largeTitleDisplayMode = .never
} else {
print("lower than IOS 11 Screen")
// Fallback on earlier versions
}
}
override func viewDidAppear(_ animated: Bool) {
super.viewDidAppear(animated)
let height: CGFloat = 100 //whatever height you want
let bounds = self.navigationController!.navigationBar.bounds
self.navigationController?.navigationBar.frame = CGRect(x: 0, y: 0, width: bounds.width, height: bounds.height + height)
}
I'm trying to make a tile based game similar to the board game memory. I want the tiles which are UiViews to flip when they are pressed a the picture gets show. Is it possible to do this? I've been looking but all seems to show methods for transitions between views.
You can use this class to do a flip like animation on tap.
class FlippingView : UIView
{
var frontView : UIImageView!
var backView : UIImageView!
var isAnimating : Bool = false
override init(frame: CGRect) {
super.init(frame: frame)
frontView = UIImageView(frame: CGRectMake(0, 0, frame.size.width, frame.size.height))
backView = UIImageView(frame: frontView.frame)
self.addSubview(frontView)
self.addSubview(backView)
self.backView.hidden = true
let tapRecognizer = UITapGestureRecognizer(target: self, action: "flip")
self.addGestureRecognizer(tapRecognizer)
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func flip()
{
if isAnimating {
return
}
isAnimating = true
if (backView.hidden)
{
frontView.layer.transform = CATransform3DMakeRotation(0, 0, 0, 0)
self.backView.layer.transform = CATransform3DMakeRotation(3.14/2, 0, 1, 0)
self.backView.hidden = false
UIView.animateKeyframesWithDuration(2, delay: 0, options: nil, animations: {
UIView.addKeyframeWithRelativeStartTime(0, relativeDuration: 0.5, animations: {
self.frontView.layer.transform = CATransform3DMakeRotation(3.14/2, 0, 1, 0)
})
UIView.addKeyframeWithRelativeStartTime(0.5, relativeDuration: 0.5, animations: {
self.backView.layer.transform = CATransform3DMakeRotation(3.14, 0, 1, 0)
})
}, completion: { (finished) -> Void in
self.isAnimating = false
self.frontView.hidden = true
})
}
else
{
backView.layer.transform = CATransform3DMakeRotation(3.14, 0, 1, 0)
self.frontView.layer.transform = CATransform3DMakeRotation(3.14/2, 0, 1, 0)
self.frontView.hidden = false
UIView.animateKeyframesWithDuration(2, delay: 0, options: nil, animations: {
UIView.addKeyframeWithRelativeStartTime(0, relativeDuration: 0.5, animations: {
self.backView.layer.transform = CATransform3DMakeRotation(-3.14/2, 0, 1, 0)
})
UIView.addKeyframeWithRelativeStartTime(0.5, relativeDuration: 0.5, animations: {
self.frontView.layer.transform = CATransform3DMakeRotation(0, 0, 1, 0)
})
}, completion: { (finished) -> Void in
self.isAnimating = false
self.backView.hidden = true
})
}
}
}
You can use it like this
override func viewDidLoad() {
flippingView = FlippingView(frame: CGRectMake(100, 100, 100, 100))
flippingView.frontView.image = UIImage(named: "1.png")
flippingView.backView.image = UIImage(named: "2.png")
self.view.addSubview(flippingView)
}
