ios - Xcode 6.3 Storyboard Autolayout Constraints -


this storyboard:

storybaord

this ipad simulator:

ipad simulator

for constraints go bottom right , click on button has triangle 2 extruding bars (it sort of looks star wars fighter triangle cockpit). scroll down section says view in view controller click on clear constraints. go same button time click add missing constraints.

why happening? how can fix it?

adding missing constraints doesn't mean "add constraint think better in project". xcode adds constraints keep in place, may (or may not) want.

to paint control in place without ambiguity need @ least 4 constraint, 2 on each axe (two x, 2 y). recommend clear constraints, , start control control, adding constraints.

some tips:

  • you can set constraints, move control, ask xcode refresh constraints new position update constraints option. update frames option opposite: given set of constraints, repaints control in right position.

update frames

  • use assistant editor split xcode view, can select preview , have while designing storyboard , see how looks. can add different devices see how fits (little + button @ bottom)

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
