为了确保我拥有正确的所有代码,这是我的头文件:

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController <UIImagePickerControllerDelegate,UINavigationControllerDelegate> {

    IBOutlet UIImageView *imageView;
    IBOutlet UIButton *choosePhoto;
    IBOutlet UIButton *takePhoto;

}

@property(nonatomic, retain) UIButton *choosePhoto;

@property(nonatomic, retain) UIButton *takePhoto;

@property(nonatomic, retain) UIImageView *imageView;

-(IBAction)getPhoto:(id)sender;
-(IBAction)takePhoto:(id)sender;

@end

然后这是我的实现:

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

@synthesize imageView,choosePhoto,takePhoto;

- (void)viewDidLoad
{
    [super viewDidLoad];

}

-(IBAction)getPhoto:(id)sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeSavedPhotosAlbum;
    [self presentViewController:picker animated:YES completion:nil];
}

-(IBAction)takePhoto:(id)sender {

    UIImagePickerController *picker2 = [[UIImagePickerController alloc] init];
    picker2.delegate = …
