将表单 UIView 委托给 UIViewController

Question

I have UIView, what called Popup and poping from UIViewContorller(ParentVC) On UIView I have 4 buttons. When buttons is pressed, it needs to open new Controllers from(ParentVC). I am using Delegate, were is my mistake?

//Popup.h
@protocol PopupDelegate
@required

- (IBAction)stepOfRestoration:(id)sender;
- (IBAction)clientCall:(id)sender;
- (IBAction)readyTo:(id)sender;
- (IBAction)givePhone:(id)sender;

@end

@interface Popup : PSCustomViewFromXib

@property (nonatomic, assign) id <PopupDelegate> delegate;
@property (strong, nonatomic) IBOutlet UIView *view;

- (IBAction)stepOfRestoration:(id)sender;
- (IBAction)clientCall:(id)sender;
- (IBAction)readyTo:(id)sender;
- (IBAction)givePhone:(id)sender;

In .mi have this:

@synthesize delegate;
....
- (IBAction)stepOfRestoration:(id)sender {
 [self.delegate buttonPressed];
}

And this is Parent .m

    ...
    CGRect rect = CGRectMake(0,0,200,300);
    Popup *popup1 = [[Popup alloc] initWithFrame:rect];
    popup1.delegate = self;
   ....

-(void)buttonPressed {
[self performSegueWithIdentifier:@"infoSegue" sender:nil];
}

So were is my mistake?

Answer 1

You don't have a method called buttonPressed in your protocol, you need to call a method in your protocol, eg

Popup.m
- (IBAction)buttonPressed:(id)sender {
   [self.delegate stepOfRestoration:sender];
}

Parent.m
- (IBAction)stepOfRestoration:(id)sender {
   // some code
}

Link to long winded but hopefully helpful tutorial, good luck.

Answer 2

In your Parent .m , you must conform all the methods which are defined in protocol. In your Parent.m file, buttonPressed method is not present in protocol. So update the name of below method with buttonPressed as follow:-

Update below code at Popup.h while declaring PopupDelegate methods

---

- (IBAction)stepOfRestoration:(id)sender;

With

---

-(void)buttonPressed;

Answer 3

you shouldn't add IBAction methods in your protocol

instead add following methods corresponding each button action

//Popup.h

@protocol PopupDelegate
@required

- (Void)stepOfRestoration:(id)sender;
- (Void)clientCall:(id)sender;
- (Void)readyTo:(id)sender;
- (Void)givePhone:(id)sender;

@end

and call these protocol methods in corresponding button action methods

eg //Popup.m

- (IBAction)stepOfRestoration:(id)sender {
 [self.delegate stepOfRestoration:sender];
}

and //Parent.m

-(Void)stepOfRestoration:(id)sender{
// code here
}
