ios - UIImage not clipped by clipping path -


i have uiview subclass contains uiimageview. want image appear circular, did this:

- (void)drawrect:(cgrect)rect {     cgcontextref ctx = uigraphicsgetcurrentcontext();     cgcontextsavegstate(ctx);     cgpathref clippath = [uibezierpath bezierpathwithroundedrect:rect cornerradius:17].cgpath;     cgcontextaddpath(ctx, clippath);     cgcontextclip(ctx);     [self.imageview.image drawinrect:rect];     cgcontextrestoregstate(ctx); }

however, images not circular, regular rectangles. what's issue?

ac couple options have either breate cornerradius on uiimageview appears circular or remove uiimageview uiview's subviews.

in first case don't need have custom drawing since circle picture want drawn in uiimageview cornerradius (and clipstobounds enabled).

in second don't need uiimageview @ all, uiimage. uiimageview way display uiimage on screen, , if that's taken care of in custom drawing of view don't need uiimageview.

given these options believe uiimageview cornerradius efficient. custom drawing takes bit of processor time uiimageview take care of you.

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 edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is)..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 .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
