i perform these actions inside single evaluation, if possible: split string input parts according separator separator apply function fnc(string) -> string every part rejoin parts string result using same separator separator that's all. the best figure out (this in vb) result = input.split(separator).aggregate(string.empty, function(result, part) _ result & if(result = string.empty, string.empty, separator) & fnc(part)) as can see, ugly because aggregate() needs initialization in 1st parameter (if aggregate() used without first parameter, doesn't call fnc() 1st element of array) this approach forces if() usage, otherwise separator added start of result i experimented using select() , selectmany() on array created through split() , when apply string.join() on result, i'm getting cast error(!) during runtime (build works ok) , not understand why. here effective form crashes during run...

i create uilabel following code: uilabel *textlabel = [[uilabel alloc] initwithframe:cgrectzero]; textlabel.font = [uifont systemfontofsize:30]; textlabel.backgroundcolor = [uicolor redcolor]; textlabel.text = @"0"; [textlabel sizetofit]; textlabel.center = cgpointmake(100, 100); [self.view addsubview:textlabel]; and textlabel.bounds.height seems higher text font actual height. following: but because designer marks space of 2 uilabel based on real text size, can't assign value 2 uilabel use designer's mark space, need run app in simulator check it's correct. i wan know how make uilabel sizetofit real height of text, no padding between text. there room around 0 in example because label has take account entire set of metrics font, cocoanetics has nice illustration of in blog post "understanding uifont" . example, running code on machine , putting "g" next "0", can see "g" touches bottom of label: if im...

i have aceduino board similar arduino. tried making sample led , button using demo . had notice when plug usb, led flashing couple of times. just wanna ask if normal when using usb power arduino. is there way can avoid it? thank in advance. the onboard led (pin 13) flashes couple of times to indicate arduino executing bootloader . happen every time power or reset board. you can avoid modifying bootloader inside arduino board. require avr in-system programmer (a piece of hardware program microcontrollers) burn bootloader. can use arduino board special sketch avr in-system programmer. this link explains how implement both approaches burn arduino uno's bootloader (which uses same microcontroller of clone). my advice: avoid if can.
