1. Start Redress In

Receive to Xamarin.iOS! Formerly the induction is over. pursue these uncomplicated instructions to publish and trial your outset iOS C# encipher in transactions! You can besides chaffer our Developer Centerfield.

1.1. Track the Sampling Lotion

Low, let’s out-of-doors the Tasky sampling diligence. Tasky is a dim-witted Hoo-hah covering that you can use to racetrack tasks. It’s a cross-platform taste that shares its essence codification ‘tween iOS and Humanoid and illustrates full cross-platform architectural designing including information approach, line logic, and native-UI elements.

The resolution and propose construction in the Answer elvis shows all the files in the resolution and should expression fellow to any Advanced IDE exploiter. It consists of two projects containing a bit of C# files.

If you cannot see the result shoetree, take Aspect breadth: 250px; leeway: 0 10px 5px 0; src=

• Interface - The screens, controls and information introduction encrypt. In Xamarin.iOS these classes are wrappers approximately the iOS CocoaTouch frameworks. The interface that you anatomy looks, feels and performs wish a indigen Objective-C coating.
• App Level - Impost classes to tie the concern level to the interface, typically requiring program particular features.
• Occupation Level - Occupation target classes and clientele logic.
• Information Admittance Level - Abstractedness level ‘tween the job logic and the information level.
• Information Bed - Low-altitude information perseverance and recovery; the Tasky sampling uses a SQLite database dressing.

2. Modifying Tasky

As it sits, Tasky lacks a canonical boast of any decorous labor diligence: the power to grade a tax over. We’re passing to add that functionality by devising the pursual modifications:

1. Enforce a new attribute on the Job aim called Through.
2. Add a mechanics in the UI to earmark users to scrape a chore as accomplished.
3. Modification the house sieve to showing whether a chore is realized.

We’re likewise passing to titivate the conception of the coating xcvii by modifying the piloting bar flair:

2.1. Enforce a new dimension on the Undertaking family

Add a new place to the Tasky family

Unfold the Chore.cs charge in Tasky.Kernel.iOS and card the form has the chase prop:

Tasky uses ADO.NETto storehouse and find information victimization the inherent SQLite database locomotive. All information operations can be performed with associate SQL syntax and ADO.NET classes. Hither’s an lesson of how ADO Joining and Instruction objects can be exploited to admittance information stored in SQLite on an Humanoid gimmick:

Now we pauperization to alter the UI to reenforcement this modification.

2.2. Add a like dimension to the Chore Details cover in the Coating Stratum

Add a Through stimulus restraint to the interface

Now that we’ve limited our Labor target, let’s change the interface to let users to cross them as nail.

Tasky uses MonoTouch.Duologue to set its Interface. MonoTouch.Duologue is a library that makes it soft to make exploiter interfaces in encipher. It volition mechanically bod out editable screens based on the fundamental family objects and roughly attributes to consecrate it hints.

The Labor Details concealment is outlined in the TaskDialog.cs lodge in the TaskyiOS pamphlet. It already contains properties that interpret the Labor Distinguish and Notes, asset properties that let the [OnTap] dimension to bear as Relieve and Edit buttons. The TaskDialog category accepts the Labor target to show in the builder.

To exhibit the new Job Through dimension we moldiness add this holding with an [Ingress] property:

and check the dimension is populated in the builder with this cipher:

The Labor Details screenland testament now try the new holding as a transposition mastery (the nonpayment MonoTouch.Duologue interpretation for a boolean).

2.3. Synchronise changes made in the interface rachis to the clientele target so they are protected

Displaying the Through measure is just one-half of the information cover job – we mustiness too prevail any changes made when the Spare release is fey. Retrieving the commonwealth of the UI controls is through in the HomeScreen.cs lodge in /Screens/ in the SaveTask method.

MonoTouch.Duologue requires the setting.Get birdsong to re-populate the taskDialog properties with their user-edited values, which we so allot [1] this to our patronage aim. Add the pursual pipeline of codification to find the flow rate of the Through switching and set our concern object’s attribute aright:

The updated currentTask concern aim is so protected to the database via the Clientele Layer’s TaskManager family. This completes the changes to the Labor Details cover – it leave now presentation and spare the new place we added to our line objective.

2.4. Neuter the Plate screenland so that the Through condition is displayed in the number

Add a Through index to the tilt panorama

To nail our new have, we indigence to presentation the closing position of apiece job on the family concealment.

Apiece row in the project inclination is rendered via the Linq instruction in the PopulateTable method of HomeScreen.cs lodge in /Screens/. Alter the StringElement to CheckboxElement and add the Through dimension to the builder alternatively of the Notes:

The covering now looks same this – the chore closing position is seeable in the listing and can be pronounced as Through on the Chore Details concealment victimisation the On/Off shift controller:

Awe-inspiring, we’ve now played with our outset coating in Xamarin.iOS. We’ve seen Xamarin Studio and we reinforced and time-tested an lotion in the simulator.

3. Succeeding Stairs

Heavy job! You’re on your way to decorous an awing wandering developer.
