这就是我的课程中写的内容

settingViewController.h 

@class settingViewController;

@protocol settingViewDelegate <NSObject>

- (void)modalDoneDel :(settingViewController *)controller;

@end

@interface settingViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> 

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

- (IBAction)modalDone:(id)sender;

@end

settingViewController.m 

@synthesize delegate;

- (IBAction)modalDone:(id)sender {

[self.delegate modalDoneDel:self];

}

leftViewController.h 

#import "settingViewController.h"

@interface leftViewController : UIViewController <UITableViewDataSource,        UITableViewDelegate, settingViewDelegate> 

@property (strong, nonatomic) IBOutlet UIView *menuView;

- (IBAction)test:(id)sender;

@end

leftViewController.m 

#import "leftViewController.h"

@interface leftViewController ()

@implementation leftViewController


-(void)modalDoneDel:(settingViewController *)controller{

NSLog(@"ss");
}

为什么没有出现在控制台“ss”上？哪里有错误？

可能的问题

您需要将委托分配给您的课程对象。如果你忘了这个，你的委托方法将不会被调用。

所以你必须在某处调用settingViewController。

SettingViewController * settingViewController = [settingViewController alloc]init];
settingViewController.delegate = self; // VERY IMP
