ios - Loading a nib file inside a UIViewController -

i'm experimenting on how load nib files uiviewcontroller.

i have created separate nib file called email. first noticed when view controller loaded, initwithnibname method isn't getting called. called viewdidload method manually this,

[self initwithnibname:@"email" bundle:[nsbundle mainbundle]]; 

it did not work. got warning saying expression result unused.

and searched on internet , came across this article , implemented loadview method described so,

- (void)loadview {     [super loadview];      uinib *nib = [uinib nibwithnibname:@"email" bundle:nil];     [nib instantiatewithowner:self options:nil]; } 

the method gets called still view controller empty!

can tell me i'm overlooking here , how can done?

thank you.

update:

first off, responses. voromax , svena's answers suggest should remove segues , load nibs automatically i'm not fond of. anil's answer works find , have 1 last hurdle jump.

i have multiple nib files. depending on user's selection, should load specific nib. tried was, put nibs inside array so,

- (void)loadview {     [super loadview];      nsarray *nibs = [[nsarray alloc] initwithobjects:                      [[nsbundle mainbundle] loadnibnamed:@"facsimile" owner:self options:nil],                      [[nsbundle mainbundle] loadnibnamed:@"email" owner:self options:nil],                      [[nsbundle mainbundle] loadnibnamed:@"memorandum" owner:self options:nil],                      [[nsbundle mainbundle] loadnibnamed:@"projectmemo" owner:self options:nil], nil];       self.view = [nibs objectatindex:0]; } 

and access using index self.view = [nibs objectatindex:1];. throws error *terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[__nsarraym _setviewdelegate:]: unrecognized selector sent instance 0xd56fd20'*

why error coming up? if not possible, i'm open suggestions.

thanks again. , sorry kinda dragging out bit.

use below code load view nib , use view controller's view

- (void)loadview {  [super loadview];  nsarray *nib =[[nsbundle mainbundle]loadnibnamed:@"test" owner:self options:nil]; self.view = [nib objectatindex:0]; }   

edit

load single nib according user selection. see loading of single nib

    nsarray *nib =[[nsbundle mainbundle]loadnibnamed:@"test" owner:self options:nil];   

will returns array of objects. updated question can see storing these arrays array. nib array array of 'array' objects.

 self.view = [[nibs objectatindex:0]objectatindex:0];  

will work.

but not good, load single nib according user choise
