ios - Push View Controller - Button Action sending from one view controller to another -


i looking make action button view coontroller. when button pressed, user sent view controller.

however, when running simulator , clicking button, not going next view controller. (the next view controller dashboard).

here .h file , .m file

`//  viewcontroller.h //  shopping list // //  created seenu on 2/8/16. //  copyright © 2016. rights reserved. //  #import <uikit/uikit.h>  @interface viewcontroller : uiviewcontroller  @property (weak, nonatomic) iboutlet uilabel *login; @property (weak, nonatomic) iboutlet uitextfield *emailtextfield; @property (weak, nonatomic) iboutlet uilabel *password; @property (weak, nonatomic) iboutlet uitextfield *passwordtextfield; @property (weak, nonatomic) iboutlet uibutton *button;  - (ibaction)signin:(id)sender;   @end`//  // //  viewcontroller.m //  shopping list // //  created seenu on 2/8/16. //  copyright © 2016. rights reserved. //  #import "viewcontroller.h" #import "dashboard.h"  @interface viewcontroller ()  @end  @implementation viewcontroller  @synthesize button;  - (void)viewdidload { [super viewdidload]; // additional setup after loading view, typically nib.  } - (ibaction)signin:(id)sender { dashboard *home = [[dashboard alloc] initwithnibname:@"dashboard" bundle:nil]; [self.navigationcontroller pushviewcontroller:home animated:yes]; }  - (void)didreceivememorywarning { [super didreceivememorywarning]; // dispose of resources can recreated. }  @end

make sure view controller have navigation controller. easy way of doing create navigation controller in applicationdidfinishlaunchingwithoptions in appdelegate class. set first view controller rootviewcontroller of navigationcontroller , add window. go appdelegate class , add code on there.

- (bool)application:(uiapplication *)application  didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     // override point customization after application launch.     uiviewcontroller *rootcontroller =           [[rootviewcontroller alloc]           initwithnibname:@"rootviewcontroller" bundle:nil];      uinavigationcontroller *navigationcontroller = [[uinavigationcontroller alloc]                  initwithrootviewcontroller:rootcontroller];      self.window = [[uiwindow alloc]          initwithframe:[[uiscreen mainscreen] bounds]];     [self.window addsubview:navigationcontroller.view];     [self.window makekeyandvisible];     return yes;  }

Unlimited choices in BASH case statement -

consider simple bash snippet: case $option in 1) image=${options[0]%.tar} ;; 2) image=${options[1]%.tar} ;; 3) image=${options[2]%.tar} ;; 4) image=${options[3]%.tar} ;; *) echo "invalid option" exit 1 esac in real script numbers goes 30. makes pretty long. can somehow specify cases variable? something this: case $option in $i) image=${options[$(($i-1))]%.tar} any pointer appreciated. you can match against multiple patterns in single clause: case $option in 1|2|3: echo "$option one, 2 or three" ;; esac if still typing you, can use simple pattern matching: case $option in # following matches # - single-digit numbers 0-9 # - two-digit numbers starting either 1 or 2 # - number 30 [0-9]|[12][0-9]|30) image=${options[$(($option-1))]%.tar} ;; *) echo "invalid option" 1>&2 exit 1 esac

apache - How do I stop my index.php being run twice for every user -

we've got webapp initial html served using apache , php. i noticed index.php being run twice every request. seems caused / effected rewrite rules in our .htaccess - rewritecond %{http_host} ^(www\.|hotels\.)ourdomain\.com$ [nc,or] rewritecond %{server_name} ^(www\.|hotels\.)ourdomain\.com$ [nc] rewriterule (.*) http://ourdomain.com/$1 [r=301] rewriterule ^hotels/([^/]+)/?\??(.*)$ ?d=$1&$2 [qsa] the final rule moving parameter url path query string. i.e. http://ourdomain.com/hotels/vegas?someparam=1 becomes http://ourdomain.com?d=vegas&someparam=1 if go directly query string version index.php run once. if use url redirected, index.php run twice (i'm checking adding error_log('end of index.php') file). so example going http://ourdomain.com/hotels/paris hits file twice http://ourdomain.com?d=paris hits once. i've seen this question , had @ blog mentioned , , can't find empty string url's (i've tried using yslow process). ...
