objective c - Know start and end point of a CGPathAddArc -


i want know start , endpoint of arc generated cgpath method cgpathaddarc.

i want draw portion of "ring" , think combining 2 arcs different radius , drawing 2 lines connecting start , end points.

cgpathaddarc(anillo, null, centro.x, centro.y, r1, ang1, ang2, yes); cgpathaddarc(anillo, null, centro.x, centro.y, r2, ang1, ang2, yes);

geometry figure want draw

how using arctopoint instead

void cgpathaddarctopoint (   cgmutablepathref path,   const cgaffinetransform *m,   cgfloat x1,   cgfloat y1,   cgfloat x2,   cgfloat y2,   cgfloat radius );

you specify start , end points sounds want.

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .
