前言：最近公司部門(mén)在組織團(tuán)建威兜，需要準(zhǔn)備準(zhǔn)備兩個(gè)團(tuán)建小游戲孩擂，
分別是“數(shù)字速算升級(jí)版”和“你話我猜升級(jí)版”。
小編琢磨了一下拴念，發(fā)現(xiàn)這個(gè)兩個(gè)小項(xiàng)目很適合入門(mén)iOS，故這篇文章誕生了褐缠。
本篇將介紹iOS 小游戲項(xiàng)目——數(shù)字速算升級(jí)版政鼠。
希望通過(guò)這篇文章，能夠幫助對(duì)iOS感興趣的同學(xué)快速入門(mén)iOS队魏。
效果圖如下：
效果圖
一缔俄、項(xiàng)目需求
- UI層面：
8個(gè)Label，3個(gè)Button器躏。
圖解：
UI
-
邏輯層面：
- 點(diǎn)擊出題/開(kāi)始按鈕，隨機(jī)生成三個(gè)數(shù)（兩位數(shù)及以下）和兩個(gè)運(yùn)算符（加蟹略、減登失、乘）。
- 做一個(gè)計(jì)時(shí)器挖炬，從0開(kāi)始計(jì)時(shí)揽浙，直到游戲結(jié)束，查看游戲時(shí)長(zhǎng)意敛。
- 點(diǎn)擊出題馅巷，刷新題目。
- 點(diǎn)擊結(jié)果草姻，計(jì)算出結(jié)果钓猬。
- 點(diǎn)擊開(kāi)始按鈕，出現(xiàn)一個(gè)彈窗撩独，點(diǎn)擊確定敞曹，開(kāi)始計(jì)時(shí)。
-
難題概率：
- 個(gè)位數(shù)出現(xiàn)的概率比兩位數(shù)高综膀。
- 乘法出現(xiàn)的概率比加減法低澳迫。
二、實(shí)現(xiàn)思路
- UI層面：
- 方式一：storyboard（拖控件剧劝、加約束）
- 方式二：純代碼
項(xiàng)目中橄登，我選擇的storyboard。獨(dú)立開(kāi)發(fā)時(shí)，用storyboard比較高效拢锹。
日常還是多用純代碼比較好谣妻，畢竟代碼是萬(wàn)能的~
@property (weak, nonatomic) IBOutlet UILabel *factorLabel1;
@property (weak, nonatomic) IBOutlet UILabel *factorLabel2;
@property (weak, nonatomic) IBOutlet UILabel *factorLabel3;

@property (weak, nonatomic) IBOutlet UIButton *questionButton;
@property (weak, nonatomic) IBOutlet UIButton *resultButton;
@property (weak, nonatomic) IBOutlet UIButton *startButton;
- 業(yè)務(wù)邏輯：
- 所要保存的屬性：
@property (nonatomic, strong) NSTimer *timer;//!< 計(jì)時(shí)器
- 開(kāi)始按鈕業(yè)務(wù)邏輯：
- (IBAction)startButtonClicked:(UIButton *)sender {
NSString *message = [NSString stringWithFormat:@"確定要 %@ 嗎？", sender.currentTitle];
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:nil message:message preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"取消" style:UIAlertActionStyleCancel handler:nil];
UIAlertAction *confirmAction = [UIAlertAction actionWithTitle:sender.currentTitle style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
sender.selected = !sender.selected;
self.resultButton.enabled = !self.resultButton.enabled;
if (sender.selected) {
[self resetElements];
[self startTimer];
} else {
[self stopTimer];
}
}];
[alertController addAction:cancelAction];
[alertController addAction:confirmAction];
[self.navigationController presentViewController:alertController animated:YES completion:nil];
}
- 出題按鈕業(yè)務(wù)邏輯：
- (IBAction)questionButtonClicked:(id)sender {
_questionButton.enabled = NO;
_resultButton.enabled = YES;
[self setQuestion];
if (_speechManager) {
_recordingLabel.text = @"";
_recordingLabel.layer.borderWidth = .0;
[_speechManager startRecordingWithResponse:^(NSString * _Nonnull formatString) {
self.recordingLabel.text = [formatString componentsSeparatedByString:@" "].lastObject;
}];
}
}
- 結(jié)果按鈕業(yè)務(wù)邏輯：
- (IBAction)resultButtonClicked:(id)sender {
_questionButton.enabled = YES;
_resultButton.enabled = NO;
_resultLabel.text = @([self calculate]).stringValue;
if (_speechManager) {
[_speechManager stopRecording];
_recordingLabel.layer.borderWidth = 1.0;
if ([_recordingLabel.text isEqualToString:_resultLabel.text]) {
_recordingLabel.layer.borderColor = [UIColor greenColor].CGColor;
} else {
_recordingLabel.layer.borderColor = [UIColor redColor].CGColor;
}
}
}
出題業(yè)務(wù)邏輯：
- (void)setQuestion {
_resultLabel.text = @"";
_factorLabel1.text = [self generateFactor];
_factorLabel2.text = [self generateFactor];
_factorLabel3.text = [self generateFactor];

_operatorLabel2.text = [self generateOperator];
}
//! 生成數(shù)字
- (NSString *)generateFactor {
NSUInteger r = arc4random() % 10;
NSUInteger max = r < 4? 10: r < 7? 20: r < 9? 50: 100;
NSUInteger factor = arc4random() % max;
return @(factor).stringValue;
}
//! 生成運(yùn)算符
- (NSString *)generateOperator {
NSUInteger r = arc4random() % 5;
NSString *operator = r < 2? @"+": r < 4? @"-": @"×";
return operator;
}

return result;

if ([operator isEqualToString:@"+"]) {
result += rightFactor;
} else if ([operator isEqualToString:@"-"]) {
result -= rightFactor;
} else {
result *= rightFactor;
}
return result;
}
- 重置元素邏輯：

_factorLabel1.text = @"0";
_factorLabel2.text = @"0";
_factorLabel3.text = @"0";
_operatorLabel1.text = @"+";
_operatorLabel2.text = @"+";

[_timer invalidate];
_timer = nil;
}
- (void)countUp {
NSInteger count = _recordingLabel.text.integerValue;
_recordingLabel.text = @(++count).stringValue;
}
三面褐、難點(diǎn)：難題概率

//! 生成數(shù)字
- (NSString *)generateFactor {
NSUInteger r = arc4random() % 10;
NSUInteger max = r < 4? 10: r < 7? 20: r < 9? 50: 100;
