#define KBankRadius (3)

通过tag值判断tableView不同row的位置，如果是第一个，中间部分，最后一个，绘制圆角图片

CALayer *layer = self.layer;

CAShapeLayer *maskLayer = [CAShapeLayer layer];

maskLayer.path = [self maskPathWithTag:[[dictionary objectForKey:@"bank_type"]intValue]].CGPath;

layer.mask = maskLayer;

- (UIBezierPath *)maskPathWithTag:(int) tag{

//贝塞尔实例对象

UIBezierPath *maskPath = [UIBezierPath bezierPath];

[maskPath moveToPoint:CGPointMake(KBankRadius, 0)];

switch (tag) {

case 0:

{

[maskPath addLineToPoint:CGPointMake(self.bounds.size.width, 0)];

[maskPath addLineToPoint:CGPointMake(self.bounds.size.width, self.bounds.size.height)];

[maskPath addLineToPoint:CGPointMake(0, self.bounds.size.height)];

[maskPath addLineToPoint:CGPointMake(0, 0)];

}

break;

case 1:

{

[maskPath addLineToPoint:CGPointMake(self.bounds.size.width - KBankRadius, 0)];

[maskPath addArcWithCenter:CGPointMake(self.bounds.size.width - KBankRadius, KBankRadius) radius:KBankRadius startAngle:M_PI_2 endAngle:0 clockwise:YES];

[maskPath addLineToPoint:CGPointMake(self.bounds.size.width, self.bounds.size.height)];

[maskPath addLineToPoint:CGPointMake(0, self.bounds.size.height)];

[maskPath addLineToPoint:CGPointMake(0, KBankRadius)];

[maskPath addArcWithCenter:CGPointMake(KBankRadius, KBankRadius) radius:KBankRadius startAngle:M_PI endAngle:M_PI_2 clockwise:YES];

}

break;

case 2:

{

[maskPath addLineToPoint:CGPointMake(self.bounds.size.width, 0)];

[maskPath addLineToPoint:CGPointMake(self.bounds.size.width, self.bounds.size.height - KBankRadius)];

[maskPath addArcWithCenter:CGPointMake(self.bounds.size.width - KBankRadius, self.bounds.size.height - KBankRadius) radius:KBankRadius startAngle:0 endAngle:M_PI_2 clockwise:YES];

[maskPath addLineToPoint:CGPointMake(KBankRadius, self.bounds.size.height)];

[maskPath addArcWithCenter:CGPointMake(KBankRadius, self.bounds.size.height - KBankRadius) radius:KBankRadius startAngle:-M_PI_2 endAngle:-M_PI clockwise:YES];

[maskPath addLineToPoint:CGPointMake(0, 0)];

}

break;

case 3:

{

[maskPath addLineToPoint:CGPointMake(self.bounds.size.width - KBankRadius, 0)];

[maskPath addArcWithCenter:CGPointMake(KBankRadius, KBankRadius) radius:KBankRadius startAngle:M_PI endAngle:M_PI_2 clockwise:YES];

}

break;

default:

break;

}

[maskPath closePath];

return maskPath;
