我假设这只是因为我很累..但出于某种原因,我无法让我的 UIBUTTONS 填充生成的数字。除答案外,数字是随机生成的。我相信这很简单。谢谢!
- (void)determineQ {
first = arc4random() % 1000;
second = arc4random() % 1000;
wrong1 = arc4random() % 1000;
wrong2 = arc4random() % 1000;
wrong3 = arc4random() % 1000;
while (first < second) {
first = arc4random() % 1000;
}
[question setText:[NSString stringWithFormat:@"%d - %d = ?", first, second]];
answer = first - second;
NSLog(@"%d - %d = %d", first, second, answer);
correctLetter = arc4random() % 100;
if (correctLetter <= 25) {
[ans2 setTitle:[NSString stringWithFormat:@"%d", answer] forState:UIControlEventAllEvents];
[ans2 setTitle:[NSString stringWithFormat:@"%d", wrong1] forState:UIControlEventAllEvents];
[ans3 setTitle:[NSString stringWithFormat:@"%d", wrong2] forState:UIControlEventAllEvents];
[ans4 setTitle:[NSString stringWithFormat:@"%d", wrong3] forState:UIControlEventAllEvents];
NSLog(@"The answer is A");
} else if (correctLetter <= 50) {
[ans1 setTitle:[NSString stringWithFormat:@"%d", wrong1] forState:UIControlEventAllEvents];
[ans2 setTitle:[NSString stringWithFormat:@"%d", answer] forState:UIControlEventAllEvents];
[ans3 setTitle:[NSString stringWithFormat:@"%d", wrong2] forState:UIControlEventAllEvents];
[ans4 setTitle:[NSString stringWithFormat:@"%d", wrong3] forState:UIControlEventAllEvents];
NSLog(@"The answer is B");
} else if (correctLetter <= 75) {
[ans1 setTitle:[NSString stringWithFormat:@"%d", wrong1] forState:UIControlEventAllEvents];
[ans2 setTitle:[NSString stringWithFormat:@"%d", wrong2] forState:UIControlEventAllEvents];
[ans3 setTitle:[NSString stringWithFormat:@"%d", answer] forState:UIControlEventAllEvents];
[ans4 setTitle:[NSString stringWithFormat:@"%d", wrong3] forState:UIControlEventAllEvents];
NSLog(@"The answer is C");
} else if (correctLetter <= 100) {
[ans1 setTitle:[NSString stringWithFormat:@"%d", wrong1] forState:UIControlEventAllEvents];
[ans2 setTitle:[NSString stringWithFormat:@"%d", wrong2] forState:UIControlEventAllEvents];
[ans3 setTitle:[NSString stringWithFormat:@"%d", wrong3] forState:UIControlEventAllEvents];

编辑:抱歉我不小心放了 UILabel,我的意思是 UIButtons。
最佳答案
Arcrandom 生成 float 或 double,尝试像这样将每个转换为 int:
[ans2 setTitle:[NSString stringWithFormat:@"%d", ((int)answer)] forState:UIControlEventAllEvents];
关于iPhone - 无法将 int 放入 UIButton,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/6001170/
