控制響應區(qū)域可以重寫hitTest 或者 pointInside 方法
- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event {
//系統(tǒng)默認會忽略isUserInteractionEnabled設置為NO祈秕、隱藏、alpha小于等于0.01的視圖
if (!self.isUserInteractionEnabled || self.isHidden || self.alpha <= 0.01) {
return nil;
}
if ([self pointInside:point withEvent:event]) {
for (UIView *subview in [self.subviews reverseObjectEnumerator]) {
CGPoint convertedPoint = [subview convertPoint:point fromView:self];
UIView *hitTestView = [subview hitTest:convertedPoint withEvent:event];
if (hitTestView) {
return hitTestView;
}
}
return self;
}
return nil;
}
import UIKit
class HHButton: UIButton {
var tapEndgeInsets: UIEdgeInsets = .zero
override func point(inside point: CGPoint, with event: UIEvent?) -> Bool {
if self.bounds.equalTo(self.enlargedRect()) {
return super.point(inside: point, with: event)
}else {
if enlargedRect().contains(point) {
return true
}
return false
}
}
func enlargedRect() -> CGRect {
return CGRect.init(x: self.bounds.origin.x - self.tapEndgeInsets.left, y: self.bounds.origin.y - self.tapEndgeInsets.right, width: self.bounds.size.width + self.tapEndgeInsets.left + self.tapEndgeInsets.right, height: self.bounds.size.height + self.tapEndgeInsets.top + self.tapEndgeInsets.bottom)
}
}
