使用applicationDidBecomeActive使应用程序滞后和缓慢唤醒它 [英] Using applicationDidBecomeActive makes app lag and slow after awakening it

问题描述

注意：这只会发生在我使用cocos2d和spritebuilder。

NOTE: This only happens when I use cocos2d and spritebuilder. I tried the same exact code with just a single view app which worked fine.

当使用applicationDidBecomeActive发送NSLog时，应用程序变得滞后，并在重新打开时变慢。这是一个非常简单的应用程序，所以它不必与密集的图形或进程。

When using applicationDidBecomeActive to send an NSLog, the app becomes laggy and slow upon being reopened. This is an extremely simple app so it does not have to do with intensive graphics or processes.

MainScene.m

MainScene.m

#import "MainScene.h"

@implementation MainScene

int score;

-(void)digButton {
    score++;
    scoreLabel.string = [NSString stringWithFormat:@"%i", score];
}
@end

那么这是appdelegate中的方法。 p>

then this is the method in appdelegate.

-(void)applicationDidBecomeActive:(UIApplication *)application
{
    NSLog(@"hi");
}

此方法不能与cocos2d正常工作吗？

Does this method not work correctly with cocos2d or something?

推荐答案

确保调用超级实现o CCAppDelegate方法：

Make sure to call the super implementation o CCAppDelegate methods:

-(void)applicationDidBecomeActive:(UIApplication *)application
{
    NSLog(@"hi");
    [super applicationDidBecomeActive:application];
}

$ b <

Without that the default CCAppDelegate implementation won't run, which resumes the director:

-(void) applicationDidBecomeActive:(UIApplication *)application
{
    [[CCDirector sharedDirector] setNextDeltaTimeZero:YES];
    if( [navController_ visibleViewController] == [CCDirector sharedDirector] )
        [[CCDirector sharedDirector] resume];
}
