[英]draw border on UIView using uibezierpath
我需要您幫助使用uibezierpath或類似方法在UIView上繪制此邊框。
我已經提出了這個解決方案:在另一個UIView中嵌套一個UIView,但是我認為有更好的解決方案:
- (void)viewDidLayoutSubviews {
[super viewDidLayoutSubviews];
self.theView.layer.cornerRadius = self.theView.bounds.size.width/2;
self.theView.layer.masksToBounds = YES;
UIView *borderView = [[UIView alloc] initWithFrame:CGRectMake(4, 4, CGRectGetWidth(self.theView.frame) - 8, CGRectGetHeight(self.theView.frame) - 8)];
borderView.backgroundColor = [UIColor grayColor];
borderView.layer.cornerRadius = self.theView.bounds.size.width/2;
borderView.layer.masksToBounds = YES;
self.theView.layer.borderWidth = 2;
self.theView.layer.borderColor = [UIColor redColor].CGColor;
self.theView.backgroundColor = [UIColor clearColor];
[self.theView addSubview:borderView];
}
謝謝。
您可以使用兩個貝塞爾曲線路徑在一個UIView
繪制它。 子類化UIView
並將其包含在UIView
drawRect
方法中,
-(void)drawRect:(CGRect)frame
{
UIBezierPath* ovalPath = [UIBezierPath bezierPathWithOvalInRect: CGRectMake(CGRectGetMinX(frame) + 2, CGRectGetMinY(frame) + 2.5, CGRectGetWidth(frame) - 5, CGRectGetHeight(frame) - 5)];
[UIColor.redColor setStroke];
ovalPath.lineWidth = 1;
[ovalPath stroke];
UIBezierPath* oval2Path = [UIBezierPath bezierPathWithOvalInRect: CGRectMake(CGRectGetMinX(frame) + 10, CGRectGetMinY(frame) + 10, CGRectGetWidth(frame) - 20, CGRectGetHeight(frame) - 20)];
[UIColor.lightGrayColor setFill];
[oval2Path fill];
}
