iphone - ARC Semantic Issue: No Visible @Interface for 'UIViewController' declares the selector 'loginResult:' -

i have made lot of googling title above not solutions want. have project arc uses static library service calls. when click login button credentials passed library , gets response login view controller, problems occurs. not able pass data view controller send request. here code error occurs:

- (void)loginresult:(logindata *)logdata {    [viewctrl loginresult:logdata]; ->no visible @interface 'uiviewcontroller' declares selector 'loginresult:' } 

in .h (static library class)

#import <uikit/uikit.h> @interface mobilewebmethods : nsobject {     uiviewcontroller *viewctrl; } @property (nonatomic, retain) uiviewcontroller *viewctrl; - (void)loginresult:(logindata *)logdata; 

apologies didn't notice nsobject class, there logical error here in doing.

you have created class mobilewebmethods, of type nsobject, not uiviewcontroller. need inside separate viewcontroller import file , create instance of it:

mobilewebmethods *webmethods = [[mobilewebmethods alloc] init]; 

then call:

[webmethods loginresult: ... ];
