UIImageView不会移动

Question

Just silly thing.

I placed UIImageView in the left top corner. Then make a new outlet

@IBOutlet var rocket : UIImageView

In the method ViewDidLoad I try to move this UIImageView with different properties but it doesn't

rocket.image = UIImage(named: "rocket.png")
rocket.frame = CGRectMake(200,200,200,200)
rocket.bounds = CGRectMake(200,200,200,200)
rocket.center = CGPointMake(400,400)

When I start the program an image in the UIImageView appears in the top left corner without any translation.

Answer 1

I guess you did not disables AutoLayout for your viewcontroller which is having that image.

please disable your Viewcontroller's AutoLayout property and change your code with following values so you can able to see the transformed image.

[rocket setFrame:CGRectMake(50, 50, 200, 200)];
rocket.bounds = CGRectMake(200,200,200,200);
rocket.center = CGPointMake(200,200);

Answer 2

[UIView animateWithDuration:0.3f animations:^{
        rocket.image = UIImage(named: "rocket.png")
        rocket.frame = CGRectMake(200,200,200,200)
        rocket.bounds = CGRectMake(200,200,200,200)
        rocket.center = CGPointMake(400,400)
}];
