Ios 在故事板中的两个场景之间传输图像

我在主视图控制器中有一个图像，我希望此图像在新视图控制器中显示…我知道如何获取两个场景之间的字符串值，但不知道故事板中的图像…请帮助我

Is it right way to pass UIImage to another controller...

if UIImage *img1=[UIImage imageNamed:@"1.jpg"]; and UIImageView is *newimgview  for newViewController

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"imageview"])
    {
        newViewController *nvc=segue.destinationViewController;
        nvc.newimgview.image=img1;

    }
}

只需传递

UIImage

指针，就像在

performsguewithidentifier

中传递其他数据（如

NSString

）一样，如果您有图像，您可以在ViewController中调用它，无需传递它

[UIImage imageWithContentsOfFile:filePath];

或

如果最初没有图像，可以像传递字符串一样传递它的指针。请阅读此处了解更多信息：

您可以将文件路径传递到目标视图控制器，或者如果需要，也可以传递图像。添加此方法并尝试传递图像

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {

    if ([segue.identifier isEqualToString:@"yourImageTransferSegue"]) {

            YourImageTransferViewController *destViewController = segue.destinationViewController;
            destViewController.imageObject = self.imageToBeTransfered;

    }
}

---

在YourImageTransferViewController的ViewDidLoad中，或者在任何您想使用的地方，使用图像对象作为self.imageObject是的……最终我得到了它……使用此代码

In case  UIImage *imag1=[UIImage imageNamed:@"some.png"];

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"imageview"])
    {
        newViewController *nvc=segue.destinationViewController;
        nvc.imag2=imag1; //imag2 is UIImage that globally declared in newViewController
    }
}

And in newViewController under ViewDidLoad or wherever u want to use...

self.imageview2.image=imag2;

谢谢大家

In case  UIImage *imag1=[UIImage imageNamed:@"some.png"];

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([segue.identifier isEqualToString:@"imageview"])
    {
        newViewController *nvc=segue.destinationViewController;
        nvc.imag2=imag1; //imag2 is UIImage that globally declared in newViewController
    }
}

And in newViewController under ViewDidLoad or wherever u want to use...

self.imageview2.image=imag2;
