Question

我正在尝试将图片从一个UIViewController传递到另一个UIViewController。但我没有成功。我的代码如下。

  PostGameViewController *v1=[[PostGameViewController alloc]initWithNibName:@ "PostGameViewController" bundle:nil];
  v1.theImg = imgPicture;
  [self.navigationController pushViewController:v1 animated:YES];

//“.h”

@interface PostGameViewController : UIViewController{
UIImage *img;
UIImageView *theImg;

}
@property(nonatomic,retain)IBOutlet UIImageView *theImg;

@property(nonatomic,retain)UIImage *img;

-(IBAction)clickFacebook:(id)sender;

//在“.m”

中

- (void)viewDidLoad
{
[super viewDidLoad];
[theImg setImage:img];
}

Answer 1

尝试这样，

PostGameViewController *v1=[[PostGameViewController alloc]initWithNibName:@ "PostGameViewController" bundle:nil];
        v1.theImg.image =[UIImage imageNamed:@"imagename.png"];
        [self.navigationController pushViewController:v1 animated:YES];

Answer 2

这里我在另一个视图中传递String变量，就像你可以用于图像一样。

MainView Controller中的

：

UserDetailsViewController *userDetailsViewController = [[UserDetailsViewController alloc] initWithNibName:@"UserDetailsViewController" bundle:nil];
    userDetailsViewController.ID = idUser;
    [self.navigationController pushViewController:userDetailsViewController animated:YES];

UserDetailsViewController

中的

<。>文件中的

@property(nonatomic) NSString *ID;

<。>在.m文件中（如何使用ID）

NSLog(@"ID---->%@",self.ID);

for image

UserDetailsViewController *userDetailsViewController = [[UserDetailsViewController alloc] initWithNibName:@"UserDetailsViewController" bundle:nil];
        userDetailsViewController.img = [UIImage imageNamed:@"abc.png"];
        [self.navigationController pushViewController:userDetailsViewController animated:YES];

<。>文件中的

@property(nonatomic) UIImage *img;

Answer 3

应该是

PostGameViewController *v1=[[PostGameViewController alloc]initWithNibName:@ "PostGameViewController" bundle:nil];
v1.theImg.image = imgPicture;   
[self.navigationController pushViewController:v1 animated:YES];
