You need to change the CGFrame of that UIImageViewLike so -
您需要UIImageView像这样更改 CGFrame -
[imageView setFrame:CGRectMake(100, 100, imageView.frame.size.width, imageView.frame.size.height)];
[imageView setFrame:CGRectMake(100, 100, imageView.frame.size.width, imageView.frame.size.height)];
This changes the uiimageviewpoistion to (100, 100)while keeping the height and width same. Note that you can use the above code to not only change the (x,y)position but also the size of the view. Using the below code you can animate it too :)
这将改变uiimageview位置，(100, 100)同时保持高度和宽度相同。请注意，您不仅可以使用上面的代码更改(x,y)位置，还可以更改视图的大小。使用以下代码，您也可以为其设置动画:)
If you want to animate the position change -
如果你想动画位置变化 -
[UIView animateWithDuration:0.35
delay:0.0
options: UIViewAnimationCurveEaseOut
animations:^{
[imageView setFrame:CGRectMake(100, 100, imageView.frame.size.width, imageView.frame.size.height)];
}
completion:^(BOOL finished){
NSLog(@"Done!");
}];

self.psView.frame = CGRectMake(self.wvView.frame.origin.x, self.wvView.frame.origin.y, self.psView.frame.size.width, self.psView.frame.size.height);
