ios - How to show viewcontroller from the view? -

i searched answers get uiviewcontroller uiview? , couple of other answers not successful.

my issue have button in uiview lets class1 , when click on button want load view class2 uiviewcontroller, , don't navigationcontroller in class1 unable load class2 view.

please me this.

thanks, in advance.

in general uiviews should not contain logic triggers flow of app. job of uiviewcontrollers. it's way of making design of code better , more organized.

one way use use delegate pattern in custom uiviews. here s simple setup:

in mycustomview .h file:

@class mycustomview;  @protocol mycustomviewdelegate <nsobject> @optional - (void)myviewdidtaponbutton:(mycustomview)mycustomview; @end   @interface mycustomview : uiview  @property (weak, nonatomic) id <mycustomviewdelegate> delegate;  @end 

in mycustomview .m file:

- (ibaction)didtapmybutton:(id)sender {      if ([self.delegate respondstoselector:@selector(myviewdidtaponbutton:)]) {         [self.delegate myviewdidtaponbutton:self];     } } 

then in viewcontroller, presenting view:

interface:

@interface myviewcontroller ()<mycustomviewdelegate>  @property (weak, nonatomic) iboutlet uiview *mycustomview; 

and implementation:

- (void)viewdidload {     [super viewdidload];      self.mycustomview.delegate = self; }  - (void)myviewdidtaponbutton:(mycustomview)mycustomview {     ... code presenting viewcontroller ... } 

note: if dont use parameter mycustomview sent in method, common pattern , habit send sender of delegate first parameter.

this used lot apple, e.g. in

- (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath;
