call function and change value of parameter
- by user262325
Hello everyone
I have constructed one object:
// info.h
#import <Foundation/Foundation.h>
@interface NSMyObject : NSObject
{
NSInteger i;
}
-(void) setI:(NSInteger)v;
@end
#import "info.h"
@implementation NSMyObject
-(void) setI:(NSInteger)v ;
{
i=v;
}
- (void)dealloc {
[super dealloc];
}
@end
Is it possible I call a function 'myFunction' with parameter temObj (NSMyObject)
myFunction(temObj);//temObj is NSMyObject
in the function I can change the content of parameter obj
-(void)myFunction:(NSMyObject*) obj;
{
[obj setI:0];
}
then I hope the content of temObj also can be changed.
But I check the operation on obj in function myFunction can not affect temObj where I call myFunction.
Welcome any comment
Thanks
