iphone - MainWindow-iPad.xib in xcode 4.6.3 -


now reading book head first iphone , ipad development 2nd edition(dan pilone, tracey pilone). , when, according exercise in book , need change program iphone universal in book xcode making mainwindow-ipad.xib automatically, xcode doesn't. beginning program in book has file mainwindow.xib, don't. should now? if change masterviewcontroller.xib (navigation template) changes in iphone simulator version.

rephrasing question per comment:

if smb want make universal program , xibs need different on ipad , on iphone, do?

you in appdelegate:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     self.window = [[uiwindow alloc] initwithframe:[[uiscreen mainscreen] bounds]];     // override point customization after application launch.     if ([[uidevice currentdevice] userinterfaceidiom] == uiuserinterfaceidiomphone) {         self.viewcontroller = [[hwviewcontroller alloc] initwithnibname:@"hwviewcontroller_iphone" bundle:nil];     } else {         self.viewcontroller = [[hwviewcontroller alloc] initwithnibname:@"hwviewcontroller_ipad" bundle:nil];     }     self.window.rootviewcontroller = self.viewcontroller;     [self.window makekeyandvisible];     return yes; }

that code taken straight single view template in xcode - code valid or without template.

it assumes have 2 separate xib files, 1 called "hwviewcontroller_iphone.xib" , other called "hwviewcontroller_ipad.xib". names don't matter long agree initwithnibname: string in code (you leave out '.xib' in code).

you can make xib files in xcode new > file > user interface > view

this question has answer here: illegal use of register in indirect addressing 1 answer i writing 8086 assembly program needs compile through tasm v3.1. running error can not seem fix. my data segment has following set purposes of keyboard input: parao label byte maxo db 5 acto db ? datao db 5 dup('$') what trying first character entered, first byte of datao: lea dx, datao mov bl, [dx] however, when attempt compile, error: **error** h5.asm(152) illegal indexing mode line 152 "mov bl, [dx]" any appreciated. if matters, running tasm through dosbox (my laptop running 64-bit win7) google hasn't come helpful answers. can post entirety of code if necessary. pretty sure reason can't use dx register pointer. try instead using [si], [di] or [bx]: lea bx, data0 mov al, [bx]
