如何更改我的个人资料图片图像，当我单击第二个屏幕中的完成按钮时，第一个屏幕图像应与第二个屏幕图像一起更改。我正在从图库中选择图像，该图像出现在我的第二个屏幕中，当我单击完成按钮时，如何在第一个屏幕视图控制器中设置此图像。

这是 MprofileViewController.h

    #import <UIKit/UIKit.h>
#import "AddProfileViewController.h"
@class MProfileViewController;

@interface MProfileViewController : UIViewController<UIImagePickerControllerDelegate,UITableViewDataSource,UITableViewDelegate,ImageSelectionDelegate>
{    
    NSMutableArray* titles;
    IBOutlet UITableView *mainTableView;
    IBOutlet  UIImageView *image2;
}
@property(strong,nonatomic)IBOutlet UIImageView *image2;


@property(nonatomic, retain) NSMutableArray *titles;
@property(strong,nonatomic)UITableView *mainTableView;

-(IBAction) clickEventOnImage:(id) sender;

@end

MprofileViewController.m

  #import "MProfileViewController.h"

@interface MProfileViewController ()
@end

@implementation MProfileViewController

@synthesize titles,mainTableView;
@synthesize image2;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    titles=[[NSMutableArray alloc]init];

    self.navigationItem.title = @"View Profile";
 image2.image=[UIImage imageNamed:@"hariku-indah.jpg"];
}

    // Use image
}

    // Dispose of any resources that can be recreated.
}

-(IBAction) clickEventOnImage:(id) sender{

    Avc.delegate=self;
    [self.navigationController pushViewController:Avc animated:YES];
}
- (void)viewWillAppear:(BOOL)animated
{
    [self.navigationController setNavigationBarHidden:NO];

}
@end

AddProfileViewController.h

    #import <UIKit/UIKit.h>

@protocol ImageSelectionDelegate <NSObject>
- (void) imageSelected:(UIImage*)image;
@end

@interface AddProfileViewController : UIViewController<UIImagePickerControllerDelegate, UINavigationControllerDelegate, UIActionSheetDelegate>{

// if([_delegate respondsToSelector:@selector(imageSelected:)]) { // [self.delegate imageSelected:imageView]; }

此代码在技术上是正确的。但是您忘记在 AddprofileViewController 中合成您的委托
