CGPath occupying more memory
This is a very much daunting challenge I have ever faced. Im drawing lines when the finger is moved. The lines are created such that they bypass the imageviews presnt in my drawingview. I`m using below code.
Code:-
-(void) paintLinesinContext:(CGContextRef)context{
for (Line *line in lines) {
NSMutableArray *arrayOfPoints=[line getPointsArray];
CGContextBeginPath(context);
int numberofPoints=[arrayOfPoints count] ;
开发者_开发问答CGPoint points[numberofPoints];
int index=0;
CGContextSetStrokeColorWithColor(context, [[UIColor blackColor] CGColor]);
if (line==tmpline) {
float dashPhase=10;
float dashPattern[3]={5,5};
CGContextSetLineDash(context, dashPhase, dashPattern, 2);
CGContextSetStrokeColorWithColor(context, [[UIColor redColor] CGColor]);
}
for (NSValue *pointObject in arrayOfPoints) {
points[index]= [pointObject CGPointValue];
if (index==0) {
CGContextMoveToPoint(context, points[index].x,points[index].y);
}
else {
CGContextAddLineToPoint(context, points[index].x, points[index].y);
}
index++;
}
CGContextStrokePath(context);
float dashPhase=10;
float dashPattern[3]={1,0};
CGContextSetLineDash(context, dashPhase, dashPattern, 2);
}
}
My problem is, my app is getting crashed because of low memory. When I looked into it using allocations in instruments, I noticed that CGPath is occupying more memory. Believe it or not. My app is running at 48MB and jumps to 96 MB out of which 90MB is CGPath. I don know what is the reason Can anyone help me out.
