ios - [UIScreen mainScreen].bounds is changing its size at startup on iPhone 6 -


this question has answer here:

i put breakpoint in 

int main(int argc, char *argv[]) {   int retval = uiapplicationmain(argc, argv, nil, nil);

and put break point in 

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {

i checked bounds twice , got different size.

(lldb) po [uiscreen mainscreen].bounds (origin = (x = 0, y = 0), size = (width = 375, height = 667))  (lldb) po [uiscreen mainscreen].bounds (origin = (x = 0, y = 0), size = (width = 568, height = 320))

what may change it? comparability mode iphone 5 ?

also graphics looks pixelated on iphone 6 on non retina screen. iphone 5 looks good.

it gl app , loads high res images.

something switches app in glitchy mode.

any ideas may force mode on iphone 6 in mode?

iphone 6 , iphone 5 both run same ios 10.2.1

the have designed view in ib or storyboard. first bounds represents bounds of view in storyboard. second on real device after reaching viewdidappear respect orientation.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
