Connecting the Izy Platform to iOS should be easy. In this article we discuss common problems and issues that may arise.

Using the Objective-C SDK

use the izy-iOSHost project Xcode project.

Phone Setup

Follow these steps:

• Enable developer mode

While the device is attached to computer, go in Xcode > Products > ...

• "Untrusted Developer, Your device management settings does not allow using an app from (essentially myself)... on this iPad. You can allow using these apps in Settings."

* Settings > General > Device Management > select the profile to trust

Using izy-proxy macros and functions

The SDK has syntactical parity with izy-proxy. For more information refer to izy-proxy documentation. Some of the Objective-C and CLANG features have been utilitized to simplify the workflow in the environment and achieve closer parity with Javascript environment.

CLANG Container/Collection Literals

Use NSDictionary * for representing JSON objects in conjuction with boxed literals:

monitoring.log = @{ @"key": @"service", @"msg": @{

@"action": @"start",

@"context": @{

@"key": @"value"

}

}};

See ObjectiveCLiterals reference.

CLANG property setters

Use setters to achieve better parity with js syntax and simplify function calls with single input and no return values, for example the following:

[monitoring log:@{}];

will become

monitoring.log = @{};

JS Equivalents

• split: componentsSeparatedByString
• join: componentsJoinedByString

Using Blocks as class properties to emulate js callbacks

See can-i-use-objective-c-blocks-as-properties. Note that if your dont have ARC enabled, you will need to release the block if the property was declared copy.

Using XCode Design Environment

Follow these steps:

• Place the UI component on the canvas and add the constraints
• Right-Click on the item in scenes hierarchy and drag it to the .h file to add the property and link to an outlet in the xib XML
• Add the protocol to the controller .h file (i.e. UIWebViewDelegate)

Creating a multiplatform binary framework bundle

WKWebView vs. UIWebView

We recommend using WKWebView. It supports async evaluations for hybrid applications.

ChangeLog

V7.0

• 7000006: implement loadURL for UIWebView
• 7000005: implement deviceextension.run

* refer to browser extension documentation for usage examples

* compatible with izy-proxy

• 7000004: json - implement serialization functionality
• 7000003: monitoring - implement add coupling for WKWebView

* Apple is phasing out UIWebView and is replacing UIWebView with WKWebView.

• 7000002: monitoring - extract name and action key and improve ingestion technique
• 7000001: monitoring - extract context key

V6.9

• 6900010: monitoring - fix logging filter bug
• 6900009: refactor libraries
• 6900008: string - stringConcat macro
• 6900007: asyncio - implement IZYrun macro to simplfy chain action process in ObjectiveC

NSDictionary* outcome = IZYrun(@"//inline/json?loadById", @{ @"id": @"queryObject" });

NSDictionary* queryObject = outcome[@"data"];

• 6900006: asyncio - port run and ldmod and //inline/ from izy-proxy
• 6900005: monitoring - implement log function as a property setter to simplify client code syntax
• 6900004: json/io use class method to implement the loadById functionality
• 6900003: add monitoring.log interface
• 6900002: add json/loadById interface
• 6900001: add the Objective-C SDK
