set Width & Height alone on Views in iPhone Development
提问by ChethanRao
Hey guys, I am working on an iPhone project where i need to change the width and height of a UIImageView dynamically. I have come across CGPointMake to change x & y positions alone, but what should i use for changing width & height alone??. There's something called CGSizeMake but i am not able to make it work. Can someone help...any idea abt this....???.. Thanks.

Try with this.
试试这个。
CGRect aFrame = image.frame;
aFrame.size.width = newWidth;
aFrame.size.height = newHeight;
image.frame = aFrame;
