首先了解一下官方的API说明：
- /* Return true if
point' is contained inrect', false otherwise. */
CG_EXTERN bool CGRectContainsPoint(CGRect rect, CGPoint point)
- // individual UIGestureRecognizer subclasses may provide subclass-specific location information. see individual subclasses for details
- (CGPoint)locationInView:(nullable UIView*)view; // a generic single-point location for the gesture. usually the centroid of the touches involved
方案:通过给图片添加点击手势，区分有效范围，实现不同位置的点击响应
例子：
- (void)tap:(UIGestureRecognizer *)ges {
CGPoint location = [ges locationInView:self.view];
NSLog(@"---x:%f y:%f",location.x,location.y);
for (AreaModel *areaModel in AreaList) {
CGFloat originX = floor(self.view.width * areaModel.hotAreaX.floatValue);
CGFloat originY = floor(self.view.height * areaModel.hotAreaY.floatValue);
CGFloat width = floor(self.view.width * areaModel.hotAreaWidth.floatValue);
CGFloat height = floor(self.view.height * areaModel.hotAreaHeight.floatValue);
CGRect frame = CGRectMake(originX, originY, width, height);
if(CGRectContainsPoint(frame, location)){
NSLog(@"点中了-------------");
return;
}
}
}
