i want program custom keyboard textfield. background of keyboard should transparent, when try set alpha of keyboardview, alpha of subviews changes too. how can change keyboard's alpha only? don't want set [uicolor clearcolor]. keyboardview.backgroundcolor = [uicolor colorwithred:0 green:0 blue:0 alpha:0.5]; keyboardview.alpha = 0.2; keyboardview.backgroundcolor = [[uicolor clearcolor] colorwithalphacomponent]; changing view's alpha alters view , it's subviews. if want non-drawn parts of view show what's underneath, set view's opaque flag no , set background color clearcolor.

in golang struct literals? why following literal though there variable? , aren't structs literally variable, when not const? how make sense. mytype{field: var) it has variable , yet it's "literal"? also why called "struct literal" when first initialize it? programming languages use word "literal" when referring sytactic ways construct data structure. means it's not constructed creating empty 1 , adding or subtracting go. compare: mytype{field: myvariable} to var x = new(mytype) x.field = myvariable the benefit code's appearance reflects data structure in way. downside have know layout in advance , have content initialized already, not possible, if instance, you're constructing map unknown keys.

this question has answer here: why volatile qualifier used through out std::atomic? 3 answers there has been lot of debate going on concerning usefulness of volatile in multi-threaded code. people agree, principal usecases of volatile bare metal applications such device drivers , interrupt handlers, not make variable of built-in type thread-safe. in fact, volatile has lead confusion because of this. however, has been added function overloads of std::atomic<t> types, suggests there usecase this. usecases of these operations? there general usefulness volatile in sense compiler must not optimise away accesses variable. however, in case, think it's because input may volatile - in case of const , can "add" not "remove" volatile attribute passed in paramater. thus: int foo(volatile int *a) { ... } will accept: int

i've research lot on delegate means somehow understand doesn't fit explanation. tutorial: physicsworld.contactdelegate = self and explanation: "this sets physics world have no gravity, , sets scene delegate notified when 2 physics bodies collide.

(ignore gravity part, there's line of code) a delegate is protocol, called "delegate protocol". class containing quoted line of code becomes delegate , gets messages of protocol in question. physicsworld contact delegate inform of collision. if delegate methods implemented (i.e. controller conforms delegate protocol), can take appropriate action when notified. clear?

this exercise "data structure , algorithm analysis in c", exercise 3.7. assume there 2 polynomials implemented in linked list. 1 has m terms. has n terms. exercise ask me implement multiplication of 2 polynomial in o(m^2n)(assume m smaller one). how solve this? i can give idea. suppose polynomials 1+x+x^3 , 1+x^2. create linked list p using (1,1)--->(1,1)--->(1,3) create linked list q (1,1)--->(1,2) (a,b) denotes coefficient of x^b. now each node in p, multiply each node of q. how? create node res (x,y) x= p->coeff * q->coeff. and y=p->exp+q->exp . add new node polynomial contain answer. during insertion in answer polynomial have keep in mind 2 things- i) keep sorted list (sorted against exp)(increasing maybe have takem increasing here--you can take decreasing also). ii) correct position in case add new node , if node same exp value exists add coeff , delete node insert. ok! print polynomial. the comple
