uiapplication - How to call completionHandler for performFetchWithCompletionHandler in Swift -

how can phone call completion handler background fetch in swift. following:

func application(application: uiapplication, performfetchwithcompletionhandler completionhandler: (uibackgroundfetchresult) -> void) { // completionhandler (uibackgroundfetchresultnodata) // not work :( homecoming }

can please help me? thanks,

tobi

the enum case uibackgroundfetchresult.nodata, right way is:

completionhandler (uibackgroundfetchresult.nodata)

or even:

completionhandler (.nodata)

because type can inferred closure signature

hint: when unsure function signature, or enum cases, etc., in xcode write type, in case uibackgroundfetchresult, , cmd+click go definition, or option+click popup declaration. helps lot.

assembly - What is the addressing mode for ld, add, and rjmp instructions? - hey guys know ldi (load immediate) addressing mode set immediate , st instruction addressing mode set index. however, have no thought others curious are! thanks :) the addressing modes explained in instruction set, in first few pages. in table of instructions see operands instruction determine addressing mode. mode indicated arguments assembly instruction. for example, ld had several different ways of operating, depending on arguments. 1 of them ld rd,x d number of register, such ld r3,x . ld r3,-z else (although both indirect addressing). rjmp k relative addressing, jumping pc + k + 1. add rr,rd direct register addressing. result contained in rd. assembly avr instructions
