I am currently creating an app where I need the app to speak what the user has entered.
Example: if user entered the word cat I need the app to say cat.
I am using Xcode 5. Any help will be greatly appreciated. If you understand it would be kind of like a dictation app.
first import <AVFoundation/AVFoundation.h>
the you need an AVSpeechSynthesizer:
AVSpeechSynthesizer *synthesizer = [[AVSpeechSynthesizer alloc] init];
and can use AVSpeechUtterance to speak strings:
AVSpeechUtterance *utterance = [[AVSpeechUtterance alloc] initWithString:#"textToSpeak"];
//adjust the speed
utterance.rate = AVSpeechUtteranceDefaultSpeechRate;
//set the language
utterance.voice = [AVSpeechSynthesisVoice voiceWithLanguage:#"en-us"];
//speak it
[self.synthesizer speakUtterance:utterance];

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

I want to make an easy "game". When player start the game, it plays sound (for example dog bark) and player has to guess to which animal (musical instrument..) the sound belongs to.
I dont know how to make the "logic" of this program - how to connect image with its sound.
I was thinking about something like this:
if app plays sound1 then right image is image1, if plays sound2 then right image is image2...but what if I have 100 images?
It is not possible doing it like this. Do you have any ideas please?
You will have to map the sound files with the images.
One way, as you suggested would be to prefix them with an ID, for example:
001_img.png - 001_sound.mp3
002_img.png - 002_sound.mp3
003_img.png - 003_sound.mp3
004_img.png - 004_sound.mp3
005_img.png - 005_sound.mp3
And use a code snippet below to generate the filenames:
for (int assetIndex = 0; assetIndex < 6; assetIndex++)
{
NSString *imageFilename = [NSString stringWithFormat:#"%03i_img.png", assetIndex + 1];
NSString *soundFilename = [NSString stringWithFormat:#"%03i_sound.mp3", assetIndex + 1];
}

I'm using FatFractal for my backend in a iPhone-app. Been searching the web and FatFractal docs without any luck.
I want to retrieve the latest object in a collection from a grabbag:
NSArray *result = [[Store ff] grabBagGetAllForObj:thread grabBagName:#"messages" withQuery:#"Get the latest inserted object" error:&err];
Probably the best way to do this is to construct the full query yourself and then use the standard getArrayFromUri: method. Taking your example, this would look like:
FatFractal *ff = [Store ff];
NSString *query = [NSString stringWithFormat:
#"%#/messages?sort=createdAt desc&start=0&count=1",
[ff metaDataForObj:thread].ffUrl];
NSArray *result = [ff getArrayFromUri:query];
For more info, see http://fatfractal.com/prod/docs/queries/#sorting-and-limiting-results.

Its basically mixes the sound but I want to apply equalizer effects on my sound.

Have a look at the Audio Unit Component Services Reference documentation. Specifically:
kAudioUnitType_Effect = 'aufx',
and Effect Audio Unit Subtypes:
enum {
kAudioUnitSubType_PeakLimiter = 'lmtr',
kAudioUnitSubType_DynamicsProcessor = 'dcmp',
kAudioUnitSubType_Reverb2 = 'rvb2',
kAudioUnitSubType_LowPassFilter = 'lpas',
kAudioUnitSubType_HighPassFilter = 'hpas',
kAudioUnitSubType_BandPassFilter = 'bpas',
kAudioUnitSubType_HighShelfFilter = 'hshf',
kAudioUnitSubType_LowShelfFilter = 'lshf',
kAudioUnitSubType_ParametricEQ = 'pmeq',
kAudioUnitSubType_Delay = 'dely',
kAudioUnitSubType_Distortion = 'dist',
kAudioUnitSubType_AUiPodEQ = 'ipeq',
kAudioUnitSubType_NBandEQ = 'nbeq'

I'm trying to get a UIWebView working with the following code:
NSString *urlAddress = [NSString stringWithFormat: #"http://www.wikipedia.org/wiki/%#",recipe.name];
recipe.name is the entity and property from the core data model
I used NSLog to test the recipe.name and it is outputting correctly to the console
I tried this with just a plain URL and it works fine:
NSString *urlAddress = [NSString stringWithFormat: #"http://www.wikipedia.org/wiki/soup"];
Initialize your UIWebView.
Create an NSURL-object containing your url(using +[NSURL URLWithString:] for example).
Create an NSURLRequest-object with the created NSURL-object.
load the NSURLRequest in your webView.
Voila
:)
