I am having a problem with my coding on Xcode. I am making an app in which a target appears, then you have to tap it, but the time allowed between each tap shortens gradually.
我在Xcode上的编码有问题。我正在创建一个目标出现的应用程序,然后你必须点击它,但每次点击之间允许的时间逐渐缩短。
MY PROBLEM: whenever I try and make a UILabel update after a tap, the target goes back to it's original position on my view controller. I have all relevant code here:
我的问题:每当我尝试在点击后进行UILabel更新时,目标会回到它在我的视图控制器上的原始位置。我在这里有所有相关的代码:
-(IBAction)startButtonPressed:(id)sender {
startButton.hidden = YES;
Text.hidden = YES;
targX = arc4random() %769;
targY = arc4random() % 925;
Target.center = CGPointMake(targX, targY);
Target.hidden = NO;
}
-(IBAction)targetTapped:(id)sender {
[Time invalidate];
targX = arc4random() %769;
targY = arc4random() % 925;
[self scoreAdd:(id)sender];
Target.center = CGPointMake(targX, targY);
timeMax = 5 - (Score * 0.05);
if (Score >= 90) {
timeMax = 0.5;
}
Time = [NSTimer scheduledTimerWithTimeInterval:timeMax target:self selector:@selector(Lose:) userInfo:nil repeats:NO];
}
-(void)Lose:(id)sender {
Target.hidden = YES;
Text.hidden = NO;
}
-(void)scoreAdd:(id)sender{
Score = Score + 1;
scoreLabel.text = [NSString stringWithFormat:@"Score: %li", Score];
}

#1
print targX = arc4random() %769; targY = arc4random() % 925;
print targX = arc4random()%769; targY = arc4random()%925;
in both methods , check whether you are getting proper points. And check generated points lies with in device screen.
在这两种方法中,检查你是否得到了正确的分数。并检查生成的点位于设备屏幕中。
