Early in World War I, when aircraft were first being used for military purposes, it became apparent that existing inline engines were too heavy for the amount of power needed. Aircraft designers needed an engine that was lightweight, powerful, cheap, and easy to manufacture in large quantities...
You should define custom event delegates to match the JavaScript method signatures. When a JavaScript callback on a managed event delegate occurs, the HTML Bridge marshals the JavaScript parameters by position. The first JavaScript input parameter is mapped to the first parameter on the managed metho...
Let us see one example of how to use the Objective-C model:C# نسخ bool MakeDecision () { return true; } void Setup () { var scrollView = new UIScrollView (myRect); scrollView.Delegate = new MyScrollViewDelegate (); ... } class MyScrollViewDelegate : UIScrollViewDelegate { ...
// toYAML takes an interface, marshals it to yaml, and returns a string. It will // always return a string, even on marshal error (empty string). // // This is designed to be called from a template. func toYAML(v interface{}) string { data, err := yaml.Marshal(v) if ...
