Android Specifications

Usage Examples

NOTE: Android supports only a subset of the iOS features, but will return a Promise on every call:

import { TNSFancyAlert, TNSFancyAlertButton } from "nativescript-fancyalert";

// show success
TNSFancyAlert.showSuccess(
  "Success!",
  "Fancy alerts are nice.",
  "Yes they are!"
).then(() => {
  /* user pressed the button */
});

// show error
TNSFancyAlert.showError("Error!", "Something bad happened.", "Close").then(
  () => {
    /* user pressed the button */
  }
);

TNSFancyAlert - Methods

  • showSuccess(title: string, subTitle?: string, closeBtnTitle?: string): Promise<any>
  • showError(title: string, subTitle?: string, closeBtnTitle?: string): Promise<any>
  • showNotice(title: string, subTitle?: string, closeBtnTitle?: string): Promise<any>
  • showWarning(title: string, subTitle?: string, closeBtnTitle?: string): Promise<any>
  • showInfo(title: string, subTitle?: string, closeBtnTitle?: string): Promise<any>
  • showColorDialog(
      title: string,
      subTitle?: string,
      okBtnTitle?: string,
      cancelBtnTitle?: string,
      backgroundColor?: string,
      titleTextColor?: string,
      contextTextColor?: string,
      contentImage?: any
    ): Promise<any>```
    
    

TNSFancyAlertButton (iOS only)

This class can be instantiated on iOS to configure buttons in the fancy alerts.

export class TNSFancyAlertButton {
  public label: string;
  public action: Function;
  public applyStyle: (btn: any) => void;

  constructor(model?: any) {
    if (model) {
      this.label = model.label;
      this.action = model.action;
      this.applyStyle = model.applyStyle;
    }
  }
}
  • label: display text on the button
  • action: the method to invoke when the button is tapped on
  • applyStyle: a method you can configure to style the button however you'd like using iOS properties. This method will hand back an instance of SLCButton which inherits from UIButton. You can see more of what methods are available on this class here.

Here's an example of how to setup a custom background color:

new TNSFancyAlertButton({
  label: 'Ok',
  action: () => {
    // the action to take
  },
  applyStyle: (btn: UIButton) => {
    // we can use UIButton typing when using tns-platform-declarations
    // however we can cast to any since you are likely not using SLCAlertView typings (they are in this repo if you want to use them :) )
    // refer to https://github.com/dogo/SCLAlertView/blob/develop/SCLAlertView/SCLButton.m on what properties are available to customize

    (<any>btn).buttonFormatBlock = () => {
      // set a custom backgroundColor
      return new (NSDictionary as any)([new Color('#3a3939').ios], ['backgroundColor']);
    }
  }
}),

Why the TNS prefixed name?

TNS stands for Telerik NativeScript

iOS uses classes prefixed with NS (stemming from the NeXTSTEP days of old): https://developer.apple.com/library/mac/documentation/Cocoa/Reference/Foundation/Classes/NSString_Class/

To avoid confusion with iOS native classes, TNS is used instead.
