Question

我尝试将完成的动画重定向到Google页面后，我尝试过这样做;

-(void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag
{

    [self close];
    [self.audioPlayer2 play];
    [self open];
}
-(void)close
{
    CABasicAnimation *shake1 = [CABasicAnimation animationWithKeyPath:@"position1"];
    [shake1 setDuration:1.6];
    [shake1 setRepeatCount:1];
    [shake1 setAutoreverses:YES];

    [shake1 setDelegate:self];

    firstView.frame=CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height/2);
    secondView.frame=CGRectMake(0,230 , self.view.frame.size.width, self.view.frame.size.height/2);
    [firstView.layer addAnimation:shake1 forKey:@"position1"];
    [secondView.layer addAnimation:shake1 forKey:@"position1"];

}
-(void)open
{ [[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://google.co.in"]];
}

但是我的问题是Close方法没有完成但是调用open方法。但是我需要在完成Closed方法之后然后调用Open方法

请告诉我我的代码中有什么问题

感谢高级。

我检查您的问题是否已解决后，我已更改了您的代码

-(void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag
{

    [self close];
    [self.audioPlayer2 play];

}
-(void)close
{
  [CATransaction begin];
    CABasicAnimation *shake1 = [CABasicAnimation animationWithKeyPath:@"position1"];
    [shake1 setDuration:1.6];
    [shake1 setRepeatCount:1];
    [shake1 setAutoreverses:YES];

    [shake1 setDelegate:self];

    firstView.frame=CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height/2);
    secondView.frame=CGRectMake(0,230 , self.view.frame.size.width, self.view.frame.size.height/2);
[CATransaction setCompletionBlock:^{ [self open];}];
    [firstView.layer addAnimation:shake1 forKey:@"position1"];
    [secondView.layer addAnimation:shake1 forKey:@"position1"];
 [CATransaction commit];
}
-(void)open
{ [[UIApplication sharedApplication] openURL:[NSURL URLWithString: @"http://google.co.in"]];
}

这里我使用了CATransaction，它有一个完成块处理程序。

尝试放置完成块：

-(void)close:(void(^)(void))completion
{
    CABasicAnimation *shake1 = [CABasicAnimation animationWithKeyPath:@"position1"];
    [shake1 setDuration:1.6];
    [shake1 setRepeatCount:1];
    [shake1 setAutoreverses:YES];

    [shake1 setDelegate:self];

    firstView.frame=CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height/2);
    secondView.frame=CGRectMake(0,230 , self.view.frame.size.width, self.view.frame.size.height/2);
    [firstView.layer addAnimation:shake1 forKey:@"position1"];
    [secondView.layer addAnimation:shake1 forKey:@"position1"];

    completion();
}


-(void)animationDidStop:(CAAnimation *)anim finished:(BOOL)flag
{

    [self close:^{
        [self.audioPlayer2 play];
        [self open];
    }];

}

如何在方法调用后重定向谷歌页面
