I'm loading around 500 rows of data into a List. It was okay when I had 10 rows but now that I have 500 it's extremely slow. Is there anything I can do to help it's performance?
List {
SegmentedControl(selection: $feedType) {
ForEach(FeedType.allCases.identified(by: \.self)) { type in
Text(type.rawValue)
}
}
ForEach(store.stories) { story in
NavigationButton(destination: Text("")) {
StoryRow(story: story)
}
}
}

I have a video inside my device but I want to extract the following details of the video(In flutter/dart)-
1.When the video was taken.
2.Duration of the video
3.Type of the Video
4.When the video was taken
Currently i am using Ff-mpeg plugin but it is taking too long time before it returns metadata information.
You may need to use FFMPEG as follows
import 'package:flutter_ffmpeg/flutter_ffmpeg.dart';
class VideoDetail {
final FlutterFFmpeg _flutterFFmpeg = new FlutterFFmpeg();
VideoDetail() {
_flutterFFmpeg
.getMediaInformation("<file path or uri>")
.then((info) => print(info));
}
}
Do not forget to add dependency
flutter_ffmpeg: ^0.1.1

Just as the title says, do you know any alternative of AGPushNote for Swift ?
In order to better understand what I was searching for when I found out on SO about this, I would like to .. "detect" when push notifications are incoming and app is active so I can prevent the notifications from showing up and do some of my own stuff instead.
I just published a pod that does exactly that.
Example usage:
import CWNotificationBanner
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
let message = Message(text: "You have an alert")
NotificationBanner.showMessage(message)
let message = Message("You have an alert", displayDuration: 2)
NotificationBanner.showMessage(message)
}
override func viewWillDisappear() {
super.viewWillDisappear()
NotificationBanner.cancelMessage(message, animated: false)
NotificationBanner.cancelAllMessages()
}

In Objective C we used
if([names count]>1){
// array count is greater than one
}
The same way i tried to check in swift. But the complier shouts.
Any idea??
The correct way to write it should be:
if name.count > 1 {
// Your code here
}
Your syntax is incorrect. Brackets are used in Objective-C, not Swift.
Try this:
var shoppingList = ["Eggs", "Milk"]
if(1 < shoppingList.count) {
println( "Greater than one")
}

I've tried
StackExchange.uc.setBalance(99999999);
and it was nothing more than a visual thing.
Also, I bought the power up and now I want an inspirational answer. Because I fell that the unicorns would appreciate the going.
Q: Is there a faster way to mine unicoins or set them so I can get ALL the unicoins.
EDIT:
I feel like the unicorns aren't happy with the decision I've made of asking. They're outside my house.
Unicorn edit:
We've got him. Don't come looking, he's ours now.
go to the mining page, execute the following code in your console, just keep moving your mouse over the rocks.
$('#uc-rockcanvas').mousemove(function(event) {
for(var i = 0; i < 10; i++) {
var mousedownEvent = document.createEvent ("MouseEvent");
mousedownEvent.initMouseEvent ("mousedown", true, true, window, 0,
event.screenX, event.screenY, event.clientX, event.clientY,
event.ctrlKey, event.altKey, event.shiftKey, event.metaKey,
0, null);
event.target.dispatchEvent (mousedownEvent);
}
});

I have set the placeholder text(e.g. Under 18s) of a text field(homeTeam) in storyboard. Now i want to check the condition something like below.
- (BOOL)textFieldShouldBeginEditing:(UITextField *) textField
{
if ([_homeTeam.text isEqualToString:#"e.g. Under 18s"]) { // e.g. Under18s
[_homeTeam setPlaceholder:#""];
}
}
But the condition is never getting true. What am i missing here? _homeTeam.text is blank when i used NSlog to trace. Why is it so?
Please suggest.
change your if condition, it should be _homeTeam.placeholder not _homeTeam.text because you set placeholder text not a text of UITextField.
- (BOOL)textFieldShouldBeginEditing:(UITextField *) textField
{
if ([_homeTeam.placeholder isEqualToString:#"e.g. Under 18s"]) { // e.g. Under18s
[_homeTeam setPlaceholder:#""];
}
}
You actually want to compare against the placeholder property, not text (which is input by the user).
Also, I would instead refer to textField (instead of _homeTeam directly, as you might add other text fields later), as such:
- (BOOL)textFieldShouldBeginEditing:(UITextField *) textField
{
if ([textField.placeholder isEqualToString:#"e.g. Under 18s"]) { // e.g. Under18s
[textField setPlaceholder:#""];
}
}
