I had a problem with UITableView Lagging on Scroll when there were long non-English (Persian) text in the cell (list with more than 40000 items and text with more than 1500 chars wont lag if they are English ) so I came up with this only solution that worked for me to keep the cells in an Array (just the non-English Ones) and reuse them myself instead of dequeuing again (will use normal pattern with other cell types) it works just perfect when the data is already added for the first time , adding a new Data no matter of what type messes up the table. here's the code :

func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {


            if(dataIndex[indexPath.row].cell == nil)
            {
                let cell = tableView.dequeueReusableCell(withIdentifier: "ChatRightTextCell", for: indexPath) as! ChatRightTextCell


                cell.configureCell(indexPath: indexPath)
                dataIndex[indexPath.row].cell = cell
                return cell
            }
            else
            {
                let cell = dataIndex[indexPath.row].cell
                cell.configureCell(indexPath: indexPath)
                return cell
            }

        }

note that the Table and the cells are transformed by 180 degree so the cells are stacked from bottom , so adding a new Item to the table be like :

dataIndex.insert(newData,at:0)
tableview.reloadData()


at ViewController start there's a 'for' …

Thanks for taking the time to read this. I'm confused on how to insert a comment using the YouTube API. I'm fairly new to using APIs, so I don't quite get what they are saying to do in their documentation.

I've authenticated the user using Google Sign-In for iOS with the scope

    "https://www.googleapis.com/auth/youtube.force-ssl"

Select all Open in new window

which is required to insert a comment. But now, I have to actually insert the comment and (like I've said) I don't understand how to do that. I'm using Alamofire for the request and Swift 4 as my language. I would highly appreciate it if someone could help me.

While uploading an iOS Application,Xcode Shows Application uploaded Successfully.but it is not Shown in iTunesConnect. Is there any solution?

Can someone tell me why, when viewed landscape on a mobile device (iPhone in particular), this page has the ads over the top of part of the results but when viewed portrait (or on a pc) it does not?  http://www.gopherstateevents.com/results/fitness_events/results.asp?event_type=5&event_id=745&race_id=1306

I need to integrate Apple Pays decrypted Payment Token Format into a Stripe Rest API call. This does not require any Stripe SDK's or JS files. The raw apple pay token information has already been decrypted ready for stripe to process via 'Source', 'Token', 'Charge' etc. Stripe support will not disclose the solution but acknowledge its possible, why, i am not sure? Spreedly does exactly as i am describing with Stripe, passing in the information below, but how is it correctly structured?

This is the what a decrypted Apple Pay payment token format looks like:

{"applicationPrimaryAccountNumber":"4xxxxxxxxxxxxxxx","applicationExpirationDate":"211130","currencyCode":"840","transactionAmount":1000,"deviceManufacturerIdentifier":"000000000000","paymentDataType":"3DSecure","paymentData":{"onlinePaymentCryptogram":"/random+stuff=","eciIndicator":"7"}}

Is it possible to know when other app opens?  I have an app A, and would like to get notified if someone opens other app such as Photo or any other app opens.

I'm trying to use a WebView to open a URL, everything works fine if I use "http://www.ups.com"

If I try use "http://www.ups.com/WebTracking/processInputRequest?tracknum=1Zxxxxxxxxxx"
Then i get "Error 405--Method Not Allowed"

If simply paste the above url into a browser it works just fine.

Why does WebView throw the error?

Hi, I have a UIPickerView with 2 images in each row, I would like to animate one of the images when it is selected ...I have been able to animate the whole pickerview when the selection changes (in didSelectRow), but I want to just animate one of the images

with the code below ...in the didSelectRow function how would I reference the selected "firstImage" image to apply the animation?

Instead of memoryPicker.transform I've tried...

pickerView.firstImage.transform -  which gives error: Value of type 'UIPickerView' has no member 'firstImage'
And
view.firstimage.transform -  gives error: Value of type 'UIView' has no member 'firstImage'
Thanks

[code]@IBOutlet weak var memoryPicker: UIPickerView!

func numberOfComponents(in pickerView: UIPickerView) -> Int {
    return 1
}

// The number of rows of data
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {

    return objectsToRemember.count
}

func pickerView(_ pickerView: UIPickerView, rowHeightForComponent component: Int) -> CGFloat {
    return 100
}

func pickerView(_ pickerView: UIPickerView, viewForRow row: Int, forComponent component: Int, reusing view: UIView?) -> UIView {

    let view = UIView(frame: CGRect(x: 0, y:0, width: 250, height: 100))

    let firstImage = UIImageView()
        firstImage.image = UIImage(named:objectsToRemember[row])
        firstImage.frame = CGRect(x: 0, y: 0, width: 100, height: 100)

I am very new to writing iOS apps - in fact this is the first app I am writing.  In general it is working, but on first load it is very slow to load the data (which is gets from a web service).  I added some timers to sections of the script and believe I have narrowed down the area that is slow.

Briefly the process is:

1. Get the article data (in JSON) and save it to an Article object and update table cell
2. For each article check if it has an image, if so access the image JSON to get the URL
3. Download the image and save to Article Object and update table cell
4. Display table and use placeholder image if article does not contain an image

It appears to be point 3 that causes the 'freeze'.  In subsequent uses of the app it checks the saved array of Article Objects and loads data from there, and then only adds new / updated articles and deletes old articles and therefore is much quicker.

While it is useable I would like to load the table with the text as soon as it is available and then load images in the background, save it to the object and refresh the cell once it is available.  While there are articles online with code I cannot seem to get them to work.  Either I am left with the app waiting for all the images to load, or just getting the placeholder image for all articles.

My code (for this) is currently in a couple of places.  Loading the JSON is in the TableViewController viewDidLoad() and the image …
