Iphone 如何更改我的个人资料图片当我点击“完成”按钮时，图片将在第一视图中更改？

如何更改我的个人资料图片图像，当我在第二个屏幕上单击“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Gallery中选择图像，该图像出现在我的第二个屏幕上。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该图像

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

    #import <UIKit/UIKit.h>

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

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

    IBOutlet UIImageView *imageView;
    NSData *dataImage;
}

// Delegate property
@property (nonatomic,assign) id<ImageSelectionDelegate> delegate;

@property (strong, nonatomic) IBOutlet UIImageView *imageView;
-(IBAction)back:(id)sender;
-(IBAction)done:(id)sender;

@end

AddProfileViewController.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

    #import <UIKit/UIKit.h>

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

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

    IBOutlet UIImageView *imageView;
    NSData *dataImage;
}

// Delegate property
@property (nonatomic,assign) id<ImageSelectionDelegate> delegate;

@property (strong, nonatomic) IBOutlet UIImageView *imageView;
-(IBAction)back:(id)sender;
-(IBAction)done:(id)sender;

@end

//如果[\u代表响应选择器：@selectorimageSelected:]{ //[self.delegate imageSelected:imageView]；}

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