Can I get 开发者_JS百科an image from image view? Please tell me what the code looks like..

UIImageView *imageview; //Assign to your image view
[imageview image];

Try This:

UIImage *setImg=[ UIImage imageNamed:@"testImg.png"];

To display the image in imageView

UIImageView *imgView=[UIImageView alloc]initWithImage:setImg];

To get Image from imageView

UIImage *getImg=imgView.image;

It really depends on what you want to do with the image, but if you just want to get a pointer to the image then you would do this.

UIImage *imageIWant = imageView.image;

I assume you have an UIImageView instance imageview.

Use the below to get the UIImage

UIImage* myImage = [imageview image];

---

UIImageView *imageView;
UIImage *img = imageView.image;

img is image from UIImageView imageView.
