how to pass cgrect as parameter and how to get cgrect as a return type in ipad

hi all i am going to ask basic question i searched many links for my question but none of the things not given exact result.here is my question:

I want to pass rect value and returning the same type using some transformation for that i wrote one method but it is giving me the errors i know it may be syntactically wrong please correct the below code

-(void)viewDidLoad{
    CGRect testRect=getNewRect(self.view.frame);
}

m开发者_C百科y own method is here

CGRect getNewRect(CGRect normalRect){
    //some transformation
    return tranfermedrect;
}

give me your suggestion thanks in advance..

Used following line you will solve your problem.

[self yourFunction:[NSValue valueWithCGRect:rectFrame]];

Above line is the simple method call and in objective-C you can not send CGRect as a parameter. so you have to CGRect convert into NSValue.

At called function you have get GGRect from NSValue

yourView.frame = [rect CGRectValue];

I hope it will help you.

Try with below

-(void)viewDidLoad{
    CGRect testRect= [self getNewRect:self.view.frame];
}

-(CGRect) getNewRect:(CGRect) normalRect{

    //some transformation
    return tranfermedrect;
}

Add below in .h file

  -(CGRect) getNewRect:(CGRect) normalRect ;

-(void)viewDidLoad{
    CGRect testRect= [self getNewRect:self.view.frame];
    NSLog(@"New rect %@",NSStringFromCGRect(testRect));
}

-(CGRect) getNewRect:(CGRect) normalRect{

    //some transformation
    return tranformedRect;
}

see if this works
