i am currently working on an application that allows the user to select a profile image.
I am able to select the image and display it on the iPhone screen. I want to make sure that the user has selected an image before saving all his information. I have have done some research around and have found that isAnimating() function can be used to check that the UIImageView is actually "animating"/"displaying" the user's image. Unfortunately, when I do the check
if profileImage.isAnimating() == true{
self.user.save()
self.performSegueWithIdentifier("moveToMainScreen", sender: self)
} else {
println("please select an image")
println(profileImage.isAnimating())
}
Even if profileImage is displaying ... isAnimating() always returns false. :(
I'm not sure if there is something faulty with this function or if we have to do something else.
Any help will be really appreciated. :(
You're using the wrong method. isAnimating returns YES when a UIImageView is, well, animating. UIImageView allows you to animate between an array of UIImages
see the docs for more details.
I think you will want to use the image
property. If its nil, then no image has been set.
if profileImage.image { // nil evaluates to false
self.user.save()
self.performSegueWithIdentifier("moveToMainScreen", sender: self)
} else {
println("please select an image")
// println(profileImage.isAnimating())
}
