iOS 扩大按钮的点击范围
-
首先要自定义一个按钮 重写方法
-(BOOL)pointInside:(CGPoint)point withEvent:(UIEvent *)event
{
CGRect bounds = self.bounds;
CGFloat widthDelta = 44.0 - bounds.size.width;
CGFloat heightDelta = 44.0 - bounds.size.height;
bounds = CGRectInset(bounds, -0.5 * widthDelta, -0.5 * heightDelta);
return CGRectContainsPoint(bounds, point);
} -
按照常理创建按钮
