Question

我被要求制作一个应用程序，随机提供关于他们的猫的标题。我有2个问题，我一步一步地遵循教程，没有任何效果。 1.当拍摄或选择一张照片时，它不会出现在UIImageView中，所有的东西都在故事板中被欣赏，我只是不明白。此外，我有一个IBAction制作随机标题，它按下按钮时工作正常，无论如何，当拍摄或选择图片时标题将自动显示？这是.M文件中的代码。我是一个初学者，在制作应用程序时。

#import "Generator.h"

@interface Generator ()

@end

@implementation Generator

-(IBAction)TakePhoto{
    picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    [picker setSourceType:UIImagePickerControllerSourceTypeCamera];
    [self presentViewController:picker animated:YES completion:NULL];

}
-(IBAction)ChooseExisting{
    picker2 = [[UIImagePickerController alloc] init];
    picker2.delegate = self;
    [picker2 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
    [self presentViewController:picker2 animated:YES completion:NULL];

}
-(void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    image = [info objectForKey:UIImagePickerControllerOriginalImage];
    [self dismissViewControllerAnimated:YES completion:NULL];
}

-(void) imagePickerControllerDidCancel:(UIImagePickerController *)picker {
    [self dismissViewControllerAnimated:YES completion:NULL];
}

-(IBAction)Back{
    [self dismissViewControllerAnimated:YES completion:NULL];
}

-(IBAction)random {
    int text = rand() % 10;
    switch (text) {
        case 0:
            textview.text = @"I'd Say About Average";
            break;
        case 1:
            textview.text = @"Happy but Hideous";
            break;
        case 2:
            textview.text = @"Furrific";
            break;
        case 3:
            textview.text = @"Cuddly";
            break;
        case 4:
            textview.text = @"Abby Normal";
            break;
        case 5:
            textview.text = @"Purrty";
            break;
        case 6:
            textview.text = @"Yuck";
            break;
        case 7:
            textview.text = @"Glowing";
            break;
        case 8:
            textview.text = @"AWWWWWW";
            break;
        case 9:
            textview.text = @"The Cutest";
            break;
        default:
            break;
    }
}



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

- (void)viewDidLoad
{

    [super viewDidLoad];
    // Do any additional setup after loading the view.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

任何帮助都可以。我的SDK是iOS 6.1

Answer 1

图片已自动释放。在imageView超出范围之前设置它，或保留它。如果你把它连接到任何东西，它应该留在记忆中并显示。

iPhone标题相机，imageview不显示拍摄的照片
