iPhone - 无法将 int 放入 UIButton
<p><p>我假设这只是因为我很累..但由于某种原因，我无法让我的 <strong>UIBUTTONS</strong> 填满生成的数字。除答案外，数字是随机生成的。我相信这很简单。谢谢!</p>
<pre><code>- (void)determineQ {
first = arc4random() % 1000;
second = arc4random() % 1000;
wrong1 = arc4random() % 1000;
wrong2 = arc4random() % 1000;
wrong3 = arc4random() % 1000;
while (first < second) {
first = arc4random() % 1000;
}
];
answer = first - second;
NSLog(@"%d - %d = %d", first, second, answer);
correctLetter = arc4random() % 100;
if (correctLetter <= 25) {
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
NSLog(@"The answer is A");
} else if (correctLetter <= 50) {
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
NSLog(@"The answer is B");
} else if (correctLetter <= 75) {
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
NSLog(@"The answer is C");
} else if (correctLetter <= 100) {
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
forState:UIControlEventAllEvents];
NSLog(@"The answer is D");
}
}
</code></pre>
<p>编辑:对不起，我不小心放了 UILabel，我的意思是 UIButtons。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>Arcrandom 生成 float 或 double，尝试将每个转换为 int，如下所示:</p>
<pre><code> forState:UIControlEventAllEvents];
</code></pre></p>
