The Map Kit Framework is what you use to add a map to your application. There are a number of classes found within the framework that let you provide a rich experience for your users. Today we will look at two of the basic ones. Adding a map to your app is done through the MKMapView class.
Put simply, the class allows an object to be created which provides an embeddable map interface.Cpc mcqs
Dragging a map on to a View Controller on the storyboard is enough to initialise this object and display an interactive map on the screen which you can pinch and zoom as well as pan around.
Adding more functions such as showing your current location, showing a different map type as well as other options can either be done through the attributes inspector or programatically. A number of methods and properties exist within the MKMapView class.
Properties include a mapType, zoomEnabled, scrollEnabled as well as a delegate property. Several other properties exist which we will cover over the course of the next few weeks as we expand the app to be more functional.
As you can see, the list is quite comprehensive and way more than we can cover in a single post. For that reason we will look at the first four of these and as we come to use other classes in later posts, we will look at overlays, annotations etc…. Just like the CLLocationManagerDelegatethis protocol defines the rules on how certain updates are received.
There are a number of methods found within the delegate protocol which allow you to respond to map position changes, load map data, track user location as well as manage annotation views to name a few. As we are not touching on annotations or user locations in this tutorial, today we will focus on just a small amount of these methods.
As usual, lets start with a Single View Application.
When done, add the MapKit. When done, go to ViewController. When you have added these to your app you should be able to run the app without errors. You will also notice that you can manipulate the map by panning and zooming. Lets move to the next part of the tutorial and start implementing some of the available methods.
We have two ways we can make changes to the map. The first is by using the attributes inspector. To do that, click on the MapView and on the right sidebar of Xcode, select the attributes inspector. Here you can enable and disable certain aspects of the map such as switching off zooming or showing current location.
Instead of working with just the attributes inspector, we will do this programatically as it provides far more power and is relatively simple to do.
The next step is to connect up your map as an IBOutlet. I called my map mapView and then clicked the Connect button to set up the property. The MKMapView is now a property that we can set and get information from.Posted by: admin December 20, Leave a comment.
The requests should not be handled by the html, but rather by the iOS code. I then check for the host and take the appropriate action.
This code works fine on iOS 7. But the web views appear blank on iOS 8 bug? The web views now render fine and amazingly faster! The when initialising your WKWebViewyou need to configure it with a script message handler. Name it whatever you want, but to me it seems like naming it for your app makes sense.

How do I know when I should be putting stuff in AppDelegate versus a custom class? Is there a rule or any type of analogy with another programming language like Python or PHP that uses an AppDelegate like pattern? A delegate object is an object that gets notified when the object to which it is connected reaches certain events or states. In this case, the Application Delegate is an object which receives notifications when the UIApplication object reaches certain states.
In many respects, it is a specialized one-to-one Observer pattern. The most important of these are:. Such other functionality includes:. Many people lump these things into their AppDelegate because they are lazy or they think the AppDelegate controls the whole program.
Your application delegate is the heart of your application. The Application Delegate is the class that receives application-level messages, including the applicationDidFinishLaunching message most commonly used to initiate the creation of other views. Programmers new to this language always have the same question — does the program start from a main method? Yes, you are right in this case; IOS apps also start from a main method.Orange mucus
Your main class calls the below function:. Our application needs content so objective-c uses a delegate to handle this. We implement some of the optional methods of that delegate and it behaves accordingly.
From what I understand of appDelegateis close to what an Application is in Android. Every application has a life cycle, from launching to interruptions from calls coming in, to notifications showing up. If you need your code to do something special when these system events occur then you need to write code the methods.
In Android we use onPauseonDestroyonCreate kinda callback methods to handle such system events. February 24, Ios Leave a comment. This leaves It would take 2 or more tries to make my taps register.

Shivam, thanks. GetTokens: what is the purpose of the oldCookieToken parameter? Why is the top portion of my UISegmentedControl not tappable?The UISegmented Control object automatically resizes segments to fit proportionally within their superview unless they have a specific width set. When you add and remove segments, you can request that the action be animated with sliding and fading effects.
You register the target-action methods for a segmented control using the value Changed constant as shown below. In iOS 5 and later, you can customize the appearance of segmented controls using the methods listed in Customizing Appearance. You can customize the appearance of all segmented controls using the appearance proxy for example, [UISegmented Control appearance]or just of a single control.
Similarly, when a property is dependent on the bar metrics on the iPhone in landscape orientation, bars have a different height from standardyou should make sure you specify a value for UIBar Metrics.
In the case of the segmented control, appearance properties for landscape Phone are only respected for segmented controls in the smaller navigation and toolbars that are used in landscape orientation on the iPhone. Returns the divider image used for a given combination of left and right segment states and bar metrics.

If you are bored with using the default UISegmentedControlthis might save your day. SJFluidSegmentedControl is a customizable segmented control with an interactive transition, written in Swift 3.
To run the example project, clone the repo, and run pod install from the Example directory first. Please reach out to me! CocoaPods is a dependency manager for Cocoa projects. You can install it with the following command:. SJFluidSegmentedControl can also be installed manually by simply dragging and dropping the files located in the Classes folder.
For customizing other of the available properties, create an IBOutlet of the segmented control and access them via code. It's very similar to using Interface Builder, instead you just setup the custom view in code. There are several methods to do this, here's an example:. You must implement the required data source method that returns the number of segments:. Return the titles for the segments of the segmented control, and take advantage of the NSAttributedString features to customize the text appearance using the following data source methods:.
If necessary, you can set the titles for the selected state of the segments with the help of the following data source methods:. You can also set the title color for the selected state of the segments using this data source method:. In addition, you can set a color or an array of colors to form a gradient for each segment, as well as colors for the left and right bounces with the help of the following data source methods:.
If you need a more complex layout for each segment, you can return a custom view instead with these data source methods:.

Additionaly, if you need to take control over the transitions between the segments, you can use the following delegate methods:.Hi, I would like when the number of segment is greater than 3, the user could scroll the segmentedControl. Is this posible with this framework? How could I do this?
Hi Buk, The framework itself doesn't support scrolling. Something like: scrollView. Cheers, Si. Hi there, It's a bit hard to tell with just these two lines. Mind sending more code to my email address?
Hi, Firstly thank you for this wonderful custom segmented control. However, I have two questions in mind. Is there a way to work around this?
Thanks in advance! SegmentOrganiseVertical cant. This is what I did in the sample, and it worked fine to me: self. SegmentOrganiseVertical I couldn't tell more without seeing more of your code, I'm afraid. Hi, I want to customize segment size, here we have 3 segments with same size but i want to change the size. Hi there, I'm afraid this framework doesn't support multi-sized segments.
However, I am having an Objective C project, and after installing it through Cocoa Pods, I cannot find any header files. Is the framework compatible with Objective C as well? Hi Erwin, Sorry for the late reply.
What is the AppDelegate for and how do I know when to use it?
Is there a way to add a badge counter to each of these segment views? Also, need the flexibility to place the badge counter right after the text and not on the top right corner.
Not at the moment, I'm afraid. I'll see if I can add this feature into the next version. How can we do that in new version? Is it possible to put buttons under first segment and table under second? You will also learn how easy it is to expand this framework a little bit. Besides of the traditional horizontal look, it also allows you to arrange your segments in a vertical way.
You can change the attributes of the text and segment as well. Now let start building something. Then, create a new Xcode project with the Single View Application template. Name the project whatever you like, but in this tutorial, let's use SegmentedControlSample.
Choose Swift as the language and iPhone as the devices. Now drag the SMSegmentView folder inside the framework to your project and tick "Copy items if needed". And we are now ready to create our very customised segmented control. Pretty easy, huh?
