Answer : Sadly, there is currently no way in the CSS Grid spec to style grid-gap . I came up with a solution that works well though that involves just html and css: show border grid lines only between elements For instance: if one has a 5x5 grid of squares, is the only way to get colored grid lines to fill the grid with 25 elements and apply borders to those same elements? You could do that, but grid borders do not collapse the same way that table borders can with the border-collapse property, and unlike grid gaps they'll be applied to the perimeter of your grid along with the inner borders, which may not be desired. Plus, if you have a grid-gap declaration, the gaps will separate your grid item borders much like border-collapse: separate does with table borders. grid-gap is the idiomatic approach for spacing grid items, but it's not ideal since grid gaps are just that: empty space, not physical boxes. To that end, the only way to color these gaps is to apply a backgr

Answer : OnDestroy lifecycle hook is available in providers. According to the docs: Lifecycle hook that is called when a directive, pipe or service is destroyed. Here's an example: @Injectable() class Service implements OnDestroy { ngOnDestroy() { console.log('Service destroy') } } @Component({ selector: 'foo', template: `foo`, providers: [Service] }) export class Foo implements OnDestroy { constructor(service: Service) {} ngOnDestroy() { console.log('foo destroy') } } @Component({ selector: 'my-app', template: `<foo *ngIf="isFoo"></foo>`, }) export class App { isFoo = true; constructor() { setTimeout(() => { this.isFoo = false; }, 1000) } } Notice that in the code above Service is an instance that belongs to Foo component, so it can be destroyed when Foo is destroyed. For providers that belong to root injector this will happen on application destroy, t

Answer : Objective-C You can use (see NSString Class Reference) - (id)initWithData:(NSData *)data encoding:(NSStringEncoding)encoding Example: NSString *myString = [[NSString alloc] initWithData:myData encoding:NSUTF8StringEncoding]; Remark : Please notice the NSData value must be valid for the encoding specified (UTF-8 in the example above), otherwise nil will be returned: Returns nil if the initialization fails for some reason (for example if data does not represent valid data for encoding). Prior Swift 3.0 String(data: yourData, encoding: NSUTF8StringEncoding) Swift 3.0 Onwards String(data: yourData, encoding: .utf8) See String#init(data:encoding:) Reference Prior Swift 3.0 : String(data: yourData, encoding: NSUTF8StringEncoding) For Swift 4.0: String(data: yourData, encoding: .utf8) I believe your "P" as the dataWithBytes param NSData *keydata = [NSData dataWithBytes:P length:len]; should be "buf" NSData *keydata = [NSData dataWithBytes:buf length:len]; sin

Answer : You have to set the cols attribute of the mat-grid-list dynamically depending on the screen width. You'd have to decide on which width breakpoint will the mat-grid-list render the 1-column version. HTML: <mat-grid-list [cols]="breakpoint" rowHeight="2:0.5" (window:resize)="onResize($event)"> <mat-grid-tile>1</mat-grid-tile> <mat-grid-tile>2</mat-grid-tile> <mat-grid-tile>3</mat-grid-tile> <mat-grid-tile>4</mat-grid-tile> <mat-grid-tile>5</mat-grid-tile> <mat-grid-tile>6</mat-grid-tile> </mat-grid-list> TS: ngOnInit() { this.breakpoint = (window.innerWidth <= 400) ? 1 : 6; } onResize(event) { this.breakpoint = (event.target.innerWidth <= 400) ? 1 : 6; } Stackblitz demo here Hope this helps!
