方法的重复声明dismissviewdidfinish

Question

在应用程序中有two actionsheet buttons和one modalviewcontroller在mainviewcontroller。现在两个actionsheet按钮和modalviewcontroller，我可以为每个

-(void)dismissViewDidFinish:(ModalViewController *)controller 
{ 

[self dismissModalViewControllerAnimated:YES]; 

} 

-(void)dismissViewDidFinish:(Devanagari *)controller1; 
{ 

[self dismissViewControllerAnimated:completion]; 

} 

-(void)dismissViewDidFinish:(English *)controller2; 
{ 

[self dismissViewControllerAnimated:YES]; 

} 

导致多个dismissviewdidfinish method如果我加上mainviewcontroller这三种方法，我收到红色的警告信息duplicate declaration of method dismissviewdidfinish。

任何想法如何解决这种情况。

Answer 1

对于多于1个方法，您不能有相同的名称。使用单一的dismissViewDidFinish:(UIViewController *)viewController方法，然后检查看哪个viewController完成：

- (void)dismissViewDidFinish:(UIViewController *)viewController { 
    //check to see what kind of class viewController is 
    //or use tags by setting the viewcontroller.view.tag when creating it 
}
