Question

i am building a app in which if a UIImageView hits another something happens, i am using the CGRectIntersetsRect statement, i would like to make it as accurate as i can, at the moment i have about 8 UIImageViews inside this one UIImageView and i am detecting if something hits them 8 little views, i have decided that this is not a very accurate way to go about it. The problem is that the UIImageView the other UIImageView s are in, Its a Oval, so it is complicated, i have tryed masking it, using the image.layer.radius 10.0 or whatever the code is. but this doesnt actually transform the whole frame, is there any way to actually transform the whole frame so when a UIImageView hits the Oval shape then something happens?

如果有的话,有人可以向我解释。

Thanks Harry

Answer 1

这确实很简单。综观,UIImageView具有一层,一层具有玉米特性:

imageView.layer.cornerRadius = 5.0;
imageView.layer.masksToBounds = YES;

A UIIage 观点框架是CGRect,CGRect是一条直截了当的,而一条直径没有四舍五入的特性。
