Hi! I have been posted content of ccna1 final exam (latest and only question.) I will post the answer and insert image on sunday. If you care, please subscribe your email an become a first person have full test content. Subcribe now Some question have not content because this question have images content. So that can you wait for me? SUNDAY 1. A user sees the command prompt: Router(config-if)# . What task can be performed at this mode? Reload the device. Perform basic tests. Configure individual interfaces. Configure individual terminal lines. 2. Refer to the exhibit. Host A attempts to establish a TCP/IP session with host C. During this attempt, a frame was captured with the source MAC address 0050.7320.D632 and the destination MAC address 0030.8517.44C4. The packet inside the captured frame has an IP source address 192.168.7.5, and the destination IP address is 192.168.219.24. At which point in the network was this packet captured? leaving host A leaving ATL leaving...
I don't think there is a nice predefined way to do this. However, this question has the code necessary to do it using line segments:

There is no prepackaged way to this, you must combine arcs in order to do this, apples quartzdemo project shows the code to do this, here is a reference Quartz Demo and here is the code they provide
ReplyDelete// As a bonus, we'll combine arcs to create a round rectangle!
// Drawing with a white stroke color
CGContextRef context=UIGraphicsGetCurrentContext()
CGContextSetRGBStrokeColor(context, 1.0, 1.0, 1.0, 1.0);
// If you were making this as a routine, you would probably accept a rectangle
// that defines its bounds, and a radius reflecting the "rounded-ness" of the rectangle.
CGRect rrect = CGRectMake(210.0, 90.0, 60.0, 60.0);
CGFloat radius = 10.0;
// NOTE: At this point you may want to verify that your radius is no more than half
// the width and height of your rectangle, as this technique degenerates for those cases.
// In order to draw a rounded rectangle, we will take advantage of the fact that
// CGContextAddArcToPoint will draw straight lines past the start and end of the arc
// in order to create the path from the current position and the destination position.
// In order to create the 4 arcs correctly, we need to know the min, mid and max positions
// on the x and y lengths of the given rectangle.
CGFloat minx = CGRectGetMinX(rrect), midx = CGRectGetMidX(rrect), maxx = CGRectGetMaxX(rrect);
CGFloat miny = CGRectGetMinY(rrect), midy = CGRectGetMidY(rrect), maxy = CGRectGetMaxY(rrect);
// Next, we will go around the rectangle in the order given by the figure below.
// minx midx maxx
// miny 2 3 4
// midy 1 9 5
// maxy 8 7 6
// Which gives us a coincident start and end point, which is incidental to this technique, but still doesn't
// form a closed path, so we still need to close the path to connect the ends correctly.
// Thus we start by moving to point 1, then adding arcs through each pair of points that follows.
// You could use a similar tecgnique to create any shape with rounded corners.
// Start at 1
CGContextMoveToPoint(context, minx, midy);
// Add an arc through 2 to 3
CGContextAddArcToPoint(context, minx, miny, midx, miny, radius);
// Add an arc through 4 to 5
CGContextAddArcToPoint(context, maxx, miny, maxx, midy, radius);
// Add an arc through 6 to 7
CGContextAddArcToPoint(context, maxx, maxy, midx, maxy, radius);
// Add an arc through 8 to 9
CGContextAddArcToPoint(context, minx, maxy, minx, midy, radius);
// Close the path
CGContextClosePath(context);
// Fill & stroke the path
CGContextDrawPath(context, kCGPathFillStroke);
Instead of making your own path out of lines and arcs, you can use
ReplyDelete[UIBezierPath bezierPathWithRoundedRect:cornerRadius:]
or
[UIBezierPath bezierPathWithRoundedRect:byRoundingCorners:cornerRadii:]
(the second one lets you specify which corners are rounded)
Available in iOS 3.2 or later.
