Goodmorning guys… I use this code in .ts file to take a picture:

this.camera.getPicture()
.then((imageData) => {
this.picture = ‘data:image/jpeg;base64,’ + imageData;
this.tookPicture = true;
})

I use this code in .html file to display the taken image:

This works on Android, but does not on iOS. Do you have any solution??
