Scalling UIImage on the screen size - iphone

Question

I have implemented a small method that imports an picture on the
iPhone screen, but the picture is a little bit to big for the screen.
This is the Method:
- (void)ladeImage {
id path = #"http://172.23.1.63:8080/RestfulJava/pics";
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data];
UIImageView *imgView = [[UIImageView alloc] initWithImage:img];
[self.view addSubview:imgView];
}
But is there any method to scale the picture on the iPhone screen?
Edit1:
Ok thank for your helping, but this method doesn't work, when I switch the iPhone to landscape, her is the code with your tipp:
- (void)ladeImage {
id path = #"http://172.23.1.63:8080/RestfulJava/pics";
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data];
UIImageView *imgView = [[UIImageView alloc] initWithImage:img];
[imgView setContentMode:UIViewContentModeScaleToFill];
imgView.frame = self.view.frame;
[self.view addSubview:imgView];
}
Edit2:
look this is my class:
- (void)viewDidLoad {
[self ladeImage];
[super viewDidLoad];
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
if(toOrientation == UIInterfaceOrientationPortrait || toOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
ImgMainPhoto.frame = CGRectMake(0, 0, 320, 480);
[self PortraitMode];
} else if((toOrientation == UIInterfaceOrientationLandscapeLeft ) || (toOrientation == UIInterfaceOrientationLandscapeRight)) {
ImgMainPhoto.frame = CGRectMake(0, 0, 480, 320);
[self LendscapreMode];
}
}
- (void)ladeImage {
id path = #"http://172.23.1.63:8080/RestfulJava/pics";
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data];
UIImageView *imgView = [[UIImageView alloc] initWithImage:img];
imgView.frame = self.view.frame;
imgView.contentMode = UIViewContentModeScaleToFill;
[self.view addSubview:imgView];
}

Answer 1

you should insert following code before inserting imageview to the view.
[imgView setContentMode:UIViewContentModeScaleToFill]
Also you can set/change from ScaleToFill to AspectFill or as you needed.
and problem will be soved.

Answer 2

Just change the frame to the screen size, i.e. imgView.frame = self.view.frame

Answer 3

look this is my class:
- (void)viewDidLoad {
[self ladeImage];
[super viewDidLoad];
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
// Return YES for supported orientations
if(toOrientation == UIInterfaceOrientationPortrait || toOrientation == UIInterfaceOrientationPortraitUpsideDown)
{
ImgMainPhoto.frame = CGRectMake(0, 0, 320, 480);
[self PortraitMode];
} else if((toOrientation == UIInterfaceOrientationLandscapeLeft ) || (toOrientation == UIInterfaceOrientationLandscapeRight)) {
ImgMainPhoto.frame = CGRectMake(0, 0, 480, 320);
[self LendscapreMode];
}
}
- (void)ladeImage {
id path = #"http://172.23.1.63:8080/RestfulJava/pics";
NSURL *url = [NSURL URLWithString:path];
NSData *data = [NSData dataWithContentsOfURL:url];
UIImage *img = [[UIImage alloc] initWithData:data];
UIImageView *imgView = [[UIImageView alloc] initWithImage:img];
imgView.frame = self.view.frame;
imgView.contentMode = UIViewContentModeScaleToFill;
[self.view addSubview:imgView];
}
