是否有可能在MPMovieplayercontroller中添加點線.. 如果是，那麼how..Becoz因爲可以在視圖上繪製線條。然後MPMovieplayerconteoler也是僅用於視圖..是否有可能在MPMoviePlayerController上繪製任何圖案
- (void)drawSquiggle:(Squiggle *)squiggle inContext:(CGContextRef)context
{
// set the drawing color to the squiggle's color
UIColor *squiggleColor = squiggle.strokeColor; // get squiggle's color
CGColorRef colorRef = [squiggleColor CGColor]; // get the CGColor
CGContextSetStrokeColorWithColor(context, colorRef);
// set the line width to the squiggle's line width
CGContextSetLineWidth(context, squiggle.lineWidth);
NSMutableArray *points = [squiggle points]; // get points from squiggle
// retrieve the NSValue object and store the value in firstPoint
CGPoint firstPoint; // declare a CGPoint
[[points objectAtIndex:0] getValue:&firstPoint];
// move to the point
CGContextMoveToPoint(context, firstPoint.x, firstPoint.y);
// draw a line from each point to the next in order
for (int i = 1; i < [points count]; i++)
{
NSValue *value = [points objectAtIndex:i]; // get the next value
CGPoint point; // declare a new point
[value getValue:&point]; // store the value in point
// draw a line to the new point
CGContextAddLineToPoint(context, point.x, point.y);
} // end for
CGContextStrokePath(context);
} // end method drawSquiggle:inContext:
端方法的touchesBegan：withEvent：方法
這是我已經使用的代碼.. mpPlayer是mpvideoplayer對象
但它不是能夠得出指向mpvideoplayer .. 有沒有任何出路。請幫助我..
