in my project i created a class viewTransistion
#import "viewTransition.h"
#import "quiz.h"
#import "mode.h"
#import "result.h"
#import "aboutGame.h"
#import "ViewController.h"
static UIView *cview=nil;
static quiz *quizObj=nil;
static mode *modeObj=nil;
static result *resultObj=nil;
static aboutGame *aboutGameObj=nil;
static ViewController *viewControllerObj=nil;
@implementation viewTransition
+(void) viewsTransitionCurrentView:(id)currentView toNextView:(NSString*)nextViewName
{
if(nextViewName == @"quiz")
{
quizObj = [[quiz alloc]init];
cview = quizObj.view;
NSLog(@"quizObj=%d", [quizObj retainCount]);
}
if(nextViewName == @"mode")
{
modeObj = [[mode alloc]init];
cview = modeObj.view;
NSLog(@"modeObj=%d", [modeObj retainCount]);
}
if(nextViewName == @"result")
{
resultObj = [[result alloc]init];
cview = resultObj.view;
NSLog(@"resultObj=%d", [resultObj retainCount]);
}
if(nextViewName == @"aboutGame")
{
NSLog(@"aboutGameObj=%d",[aboutGameObj retainCount]);
aboutGameObj = [[aboutGame alloc]init];
cview = aboutGameObj.view;
}
if(nextViewName == @"viewController")
{
viewControllerObj = [[ViewController alloc]init];
cview = viewControllerObj.view;
}
[UIView transitionFromView:[currentView view] toView:cview duration:2 options:UIViewAnimationOptionTransitionCurlUp completion:^(BOOL finished) {}];
[currentView release];
cview = nil;
}
@end
its purpose is to perform view transition so i don't have to write code again n again
first i created method and variables of this class as non static...
i checked on device i was getting leaks maybe because i am alloc initing and not releasing objs in if statements
if i release objs in the last i can't perform view transition because on the next view i want to go to is destroyed
......................................
to check i converted this class methods and variables to static so i can check retain counts
the reason why i converted to static...if every time new instance is created of this class i will always get retain count 1 of current instance
now for the first time i execute this it works fine but if you look at aboutGame if block the first execution prints 0 next time if i want to go again on this page the NSLog line becomes zombie???
......................................
in the last line [currentView release] is to remove root view controller ... but i didn't alloc init this i am not the owner so why i should release it.. i saw code in a book to release view controller.
......................................
which is the best way to implement this kind of situation static or non-static
i am using this class method and variable as static and its working fine no leaks no zombies no problem?????
