How to append arrow head to UIBezierPath - ios

Question

I need help in adding arrow head to UIBezierPath.
I have created multiple lines by using UIBezierPath, which are in different directions.
Now, I want to create arrow head at the end point of the line.
I tried to add UIImage to UILable using NSAttributedString to UILable with NSTextAttachment.
But, here problem is arrow head is always down. And I want to align arrow along the line.
Here is my code:
UIBezierPath *ShotPath = [UIBezierPath bezierPath];
NSValue *PointValue = [[[PathArray objectAtIndex:i] valueForKey:#"ShotPath"] objectAtIndex:k];
CGPoint FirstPoint; = [PointValue CGPointValue];
[ShotPath moveToPoint:FirstPoint];
CAShapeLayer *line = [CAShapeLayer layer];
line.lineWidth = 4.0;
line.path=ShotPath.CGPath;
line.fillColor = [UIColor clearColor].CGColor;
line.strokeColor = [UIColor colorWithRed:231/255.0 green:83/255.0 blue:73/255.0 alpha:1].CGColor;
[[BaseView layer] addSublayer:line];
NSValue *PointValue = [[[PathArray objectAtIndex:i] valueForKey:#"ShotPath"] objectAtIndex:[[[PathArray objectAtIndex:i] valueForKey:#"ShotPath"] count]-1];
CGPoint OtherPoint = [PointValue CGPointValue];
UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(OtherPoint.x-6, OtherPoint.y-8, 12, 12)];
lbl.backgroundColor =[UIColor clearColor];
NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
attachment.image = [UIImage imageNamed:#"DropDown_Icon"];
NSAttributedString *attachmentString = [NSAttributedString attributedStringWithAttachment:attachment];
lbl.attributedText = attachmentString;
[lbl setTextColor:[UIColor blackColor]];
lbl.font =[UIFont boldSystemFontOfSize:22.0];
[BaseView addSubview:lbl];
Here is my current output :

Answer:
- (void)viewDidLoad {
[super viewDidLoad];
UIBezierPath *path = [UIBezierPath bezierPath];
CGPoint point1 = CGPointMake(100, 100);
CGPoint point2 = CGPointMake(300, 300);
[path moveToPoint:point1];
[path addQuadCurveToPoint:point2 controlPoint:point1];
CAShapeLayer *shape = [CAShapeLayer layer];
shape.path = path.CGPath;
shape.lineWidth = 10;
shape.strokeColor = [UIColor blueColor].CGColor;
shape.fillColor = [UIColor clearColor].CGColor;
shape.frame = self.view.bounds;
[self.view.layer addSublayer:shape];
CGFloat angle = atan2f(point2.y - point1.y, point2.x - point1.x);
CGFloat distance = 15.0;
path = [UIBezierPath bezierPath];
[path moveToPoint:point2];
[path addLineToPoint:[self calculatePointFromPoint:point2 angle:angle + M_PI_2 distance:distance]]; // to the right
[path addLineToPoint:[self calculatePointFromPoint:point2 angle:angle distance:distance]]; // straight ahead
[path addLineToPoint:[self calculatePointFromPoint:point2 angle:angle - M_PI_2 distance:distance]]; // to the left
[path closePath];
shape = [CAShapeLayer layer];
shape.path = path.CGPath;
shape.lineWidth = 2;
shape.strokeColor = [UIColor redColor].CGColor;
shape.fillColor = [UIColor redColor].CGColor;
shape.frame = self.view.bounds;
[self.view.layer addSublayer:shape];
}
- (CGPoint)calculatePointFromPoint:(CGPoint)point angle:(CGFloat)angle distance:(CGFloat)distance {
return CGPointMake(point.x + cosf(angle) * distance, point.y + sinf(angle) * distance);
}
