Hello, I am developing a type of "note taking" App in iOS for a specific vertical market (its not just a simple note taking App, but note taking is a basic function of the App). A user will use the App to collect data (text and images) and store them in permanent storage (a data file of some sort.)

The iOS App will have a companion desktop application for the Mac, which will take the data in the "data file" collected by the iOS App and perform more analytical processes. So, the system is a two part system. One part is the iOS App. portion (the data collection part) and the second portion is the Mac desktop application part to perform more in-depth analytical functions.

It kind of looks like this  ---   iOS App >>>> (data file) <<<< Mac Application.  [The "data file can be XML, a database, etc.]

*** My question is:   How can I share the "data file" between the iOS device and the Mac portion of the system. By "share" I mean, how do I collect the data on the iOS App, put it into a permanent storage file and then send that file to the custom Mac desktop application?

Note: I am not asking how to share unassociated files between devices.

Also, if anyone has an example of how to create Apps with data storage, for use in CocoaTouch Mac applications, I would greatly appreciate it. I have not found any tutorials that show how this is done in a practical manner.

Thank you for your help.

IOS app in swift
Single view controller with a table view. Project runs as it's supposed to. My question is: How do I move my table view down the page a bit so I can add some text above the table view? I think the answer is in this extension class so I'll post that first. Thanks!

Extension.swift

import UIKit

extension UIView {
    
    func anchor (top: NSLayoutYAxisAnchor?, left: NSLayoutXAxisAnchor?, bottom: NSLayoutYAxisAnchor?, right: NSLayoutXAxisAnchor?,  paddingTop: CGFloat, paddingLeft: CGFloat, paddingBottom: CGFloat, paddingRight: CGFloat, width: CGFloat, height: CGFloat, enableInsets: Bool) {
        var topInset =  CGFloat(0)
        var bottomInset = CGFloat(0)
        
        if #available(iOS 11, *), enableInsets {
            let insets = self.safeAreaInsets
            topInset = insets.top
            bottomInset = insets.bottom
            
            print("Top: \(topInset)")
            print("bottom: \(bottomInset)")
        }
        
        translatesAutoresizingMaskIntoConstraints = false
        
        if let top = top {
           self.topAnchor.constraint(equalTo: top, constant: paddingTop+topInset).isActive = true
        }
        if let left = left {
            self.leftAnchor.constraint(equalTo: left, constant: paddingLeft).isActive = true
        }
        if let right = right {
            rightAnchor.constraint(equalTo: right, constant: -paddingRight).isActive = true
        }
        if let bottom = bottom {

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

When photo app is opened, I want get event so that I can launch my app. Is there a way to do that?

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?

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 …

Hello:

I'm considering taking an online class to learn Swift programming for creating iPhone apps.

But, my laptop has Microsoft Windows 7--not Mac's OCX operating system.

Is it possible to install some sort of "runtime" version of OCX on a Windows laptop?  Also, is it possible to do so without cost?  :)

Thank you!

Is there a way to do Xcode development and maintain the projects in such a way that if I have to switch between 2 - 3 macs I still have access to my projects.  Right now doing a course on Swift and that would be helpful

Thanks

Is Windows Xamarin the next great tool for Cross platform mobile development? What are the alternative tools available and their advantages?

Is jquery mobile another great tool for Cross platform mobile development?

Hello:

Although I have many skills outlined on my resume, I want to add another practical skill, in case my current skills become obsolete.

So, I have been toying with the idea of teaching myself Swift or some other iOS programming language in order to be able to create apps for the iPhone.

Out of the many new business skills a professional could learn, would this be the best?  

If so, how long does it take to learn and is it extraordinarily difficult?  Are there are good and free tutorials online that will successfully teach the lay person such a programming language?

Thanks!

As all "great" projects start, my wife asked me to build an app for their small teacher organisation. I'm new to development of IOS, but have worked in java, so I've made progress in getting up to speed with Swift and building up the framework of the app and getting it operational.

However, it dawned on me that I don't have an understanding of do's and don'ts when building a secure app. The books I've read focused on the UI more than the data itself. With the current project, I don't have risk that I need to worry about. But would like to use this app as a ginnie pig.  I'd like to know what are things I should be doing or adding into a iOS app to ensure it's secure and protected. I am not asking from a UI Pov (Apples KB documents provided me with that), but more on the lines of protecting the data if I was sending secure data from the app to a cloud DB (I.e. Firebase) or storing user profile or credentials in the apple "Core Data".
