定义一个按钮连接以下方法:

- (IBAction)selectExistingPicture {
    if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) 
        {
        UIImagePickerController *picker = [[UIImagePickerController alloc] init];
        picker.delegate = self;
        picker.allowsImageEditing = YES;
        picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        [self presentModalViewController:picker animated:YES];
        [picker release];
    }
    else {
        UIAlertView *alert = [[UIAlertView alloc] 
                              initWithTitle:@"访问图片库错误" 
                              message:@"" 
                              delegate:nil 
                              cancelButtonTitle:@"OK!" 
                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }
}

再调用以下委托：


#pragma mark UIImagePickerControllerDelegate
- (void)imagePickerController:(UIImagePickerController *)picker 
        didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo 
{
        imageView.image = image;        //imageView为自己定义的UIImageView                
    [picker dismissModalViewControllerAnimated:YES];

}
