How to retrieve the pretext before an array in iOS Objective C (parse) -


array object @ index 0---:

 <merchandise:aw9jgreryq:(null)>  {     acl = "<pfacl: 0x201b2590>\";      coverphotos = "<itemphotos:l5ln3zn5rm>\";     item = ugh;     listingprice = 356;     originalprice = "25)";     user = "<pfuser:kdrfesaja3>"; },

i have implemented ios app using parse.com

in have array of objects (array of dictionaries)

in have print 1st object of array..

i have pre text merchandise:aw9jgreryq:(null before every object / dictionary related object id

i want pretext " merchandise:aw9jgreryq:(null) " or atleast "aw9jgreryq"

how ..>?

total entire array of objects is

array-------

(     "<merchandise:aw9jgreryq:(null)>       {\n    acl = \"<pfacl: 0x201b2590>\";\n    coverphotos = \"<itemphotos:l5ln3zn5rm>\";\n    photos = \"<pfrelation: 0x201bff80>(<00000000>.(null) -> itemphotos)\";\n    brand = \"baby gap\";\n    description = \"\\nfight\";\n    item = ugh;\n    listingprice = 356;\n    originalprice = \"25)\";\n    user = \"<pfuser:kdrfesaja3>\";\n}",       "<merchandise:bmpfijerwi:(null)>       {\n    acl = \"<pfacl: 0x201a2300>\";\n    coverphotos = \"<itemphotos:4pm7vx7q26>\";\n    photos = \"<pfrelation: 0x2019a490>(<00000000>.(null) -> itemphotos)\";\n    brand = \"3 pommes\";\n    description = sett;\n    item = udder;\n    listingprice = 245;\n    originalprice = 245;\n    user = \"<pfuser:kdrfesaja3>\";\n}"  )

it seems have 2 options this. either parse each 1 out string (definitely less elegant/way uglier way). or looks more array of arrays contain string , dictionary.

if ends being second option, grab object @ index 0 twice pretext looking for. however, if thats no avail..then can go so:

//convert object nsstring nsstring *converted = (nsstring*)[yourarray objectatindex:i]; //or..your may need nsstring *converted = [nsstring stringwithformat:@"%@",[yourarray objectatindex:0]]; nsarray *firstsplitterarray = [converted componentsseparatedbystring:@"<"];//split < nsstring *partialsplit = [splitterarray objectatindex:0]; nsarray *secondsplitterarray = [partialsplit componentsseparatedbystring:@">"];//split > nsstring *yourpretext = [secondsplitterarray objectatindex:0];//final step  //now yourpretext should equal merchandise:aw9jgreryq:(null)

i wrote according first code snippet. if there leading quotation mark or something, you'll need change indexes. gives idea. print statements verify arrays @ each step , go. not cleanest, if in pinch work.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
