iphone - Objective-c 同一 View 中的多个委托(delegate) - ECSlidingViewController

Question

我开始测试ECSlidingViewController在我尝试访问 FirstTopViewController 后，我遇到了一个大麻烦 - 因为在 FirstToViewController 中我已经有了 ZBarReaderDelegate已实现，并且委托(delegate)的所有示例都没有触发我的委托(delegate)中的任何方法。

基本上我有这些东西:

FirstTopViewController.h

#import ...MyStuff...
#import "UnderRightViewController.h"

@interface FirstTopViewController : UIViewController <RightViewDelegate, ZBarReaderDelegate>

@property (weak, nonatomic) IBOutlet UITextView *labelTotal; 

@end

FirstTopViewController.m

#import "FirstTopViewController.h"

@implementation FirstTopViewController
- (void)setTotalViewController:(UnderRightViewController*)controller didTotalChange:(NSString*)total
{
    //labelTotal.text = total;
    NSLog(@"I'm here!!! and received %@", total);
}

从另一边我有

UnderRightViewController.h

#import <UIKit/UIKit.h>
#import "ECSlidingViewController.h"

@class UnderRightViewController;

@protocol RightViewDelegate <NSObject>

- (void)setTotalViewController:(UnderRightViewController*)controller didTotalChange:(NSString*)total;

@end

@interface UnderRightViewController : UITableViewController

@property (nonatomic, weak) id <RightViewDelegate> delegate;

@end

UnderRightViewController.m

#import "UnderRightViewController.h"

@interface UnderRightViewController ()

@end

@implementation UnderRightViewController

@synthesize delegate;

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    [delegate setTotalViewController:self didTotalChange:@"foo"];
}
@end

我一整天都在尝试解决这个难题，但我从未被 setTotalViewController 解雇。

提前致谢。

friend ，你犯了一个小错误，当你从 FirstTopViewController 导航到 UnderRightViewController 时，你需要在 FirstTopViewController.m 中执行此操作:-

 UnderRightViewController *obj = [[UnderRightViewController
                                                                  alloc] initWithNibName:@"UnderRightViewController" bundle:nil];

obj.delegate  = self; // u forget to assign protocol handler


[self.navigationController pushViewController:obj animated:YES];


[obj release];
