我想让imageView Position垂直倒置

Question

In the Below image there are two imageViews one is body imageView and another one is black tattoo imageview , Now i am getting the tatoo imageView position with the below code

appDelegate.xFloat= self.imgView.frame.origin.x;
appDelegate.yFloat= self.imgView.frame.origin.y;
appDelegate.widthFloat= self.imgView.frame.size.width;
appDelegate.heightFloat= self.imgView.frame.size.height;

Now i need to put the tattoo image in another view controller as we are seeing in the image(Here Car is in reverse position), But with the help of ( appDelegate.xFloat , appDelegate.yFloat , appDelegate.widthFloat , appDelegate.heightFloat ) these I am setting the tattooimageview frame. But i am getting the image as shown below in another view

I need to place the car image in reverse as we seen in first image. Please Guide Me

My requirement is not only rotation.. The image may be in any position like below

Answer 1

you must contructor appDelegate before use it. by:

appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate];

Answer 2

It is strange that one image is not rotating and the other one is rotating. I am assuming that one of the images is a background image or what ever, but you can use transform properties to change the rotation. Some thing similar to the code below should show you the same image in two orientations.

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

UIImageView *iv1 =[[UIImageView alloc] initWithImage:image];

[self.view addSubview:iv1];

UIImageView *iv2 = [[UIImageView alloc] initWithImage:image];

[iv2 setFrame:CGRectMake(100,100,image.size.width,image.size.height)];

[iv2 setTransform:CGAffineTransformMakeRotation(-M_PI)];

[self.view addSubview:iv2];

Answer 3

Babul, Looks like you are trying to create an image. For that you need to use some thing called ImageContext. I have given some code, where you draw an image in a context and then get the image out.

UIGraphicsBeginImageContext(CGSizeMake(300,300));

UIImage *image = [UIImage imageNamed:@"breakpoint place.png"];

[image drawAtPoint:CGPointMake(0,0)];

UIImage *image2 = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();

UIImageView *iv = [[UIImageView alloc] initWithImage:image2];

[iv setFrame:CGRectMake(100,100,image2.size.width,image2.size.height)];

[self.view addSubview:iv];
