According to the above concept, the page layout is about a 3*3 9-square grid. It is generally used to select a number exercise, and there is no special way to get it done. In the Demo implementation, the above interface is mainly composed of numbers 1, therefore, you need a method to generate a random array. The method is as follows. The general rule for generating a random and non-repeating array is to first create an array. Then, you need to disrupt the array, use a random number to randomly generate an index:-(NSArray *) getDataArray {// The array NSMutableArray * arr = [NSMutableArray array]; for (NSInteger I = 1; I <10; I ++) {[arr addObject: @ (I)] ;}nsinteger count = [arr count]; // generates a random array for (NSInteger I = 0; I <count; I ++) {NSInteger index = arc4random () % (count-I) + I; [arr exchangeObjectAtIndex: index withObjectAtIndex: I];} return arr;} assign the value in the array to the button on the page:-(void) initButtonTitle {// variable array of the instantiated result set self. resultArr = [NSMutableArray array]; NSArray * arr = [self getDataArray]; for (UIButton * button in self. visionButtons) {NSString * result = [arr [button. tag-1] stringValue]; [button setTitle: result forState: UIControlStateNormal]; // you need to reset the background and status of the button when you start again. [button setBackgroundColo R: [UIColor yellowColor]; [button setEnabled: YES];} [_ timerLabel setText: @ "00:00"]; self. timer = [NSTimer scheduledTimerWithTimeInterval: 0.1 invocation: nil repeats: YES];} call the corresponding program at viewDidLoad startup: 1 [self initButtonTitle]; this step is basically completed by the program, followed by timing. After the completion of the statistics, take a look at the specific effect, and then see the code may be better: the basic function is to set the background color of the button. Can you click, time, reset, or pop-up button to display the previously clicked results? Step by step analysis: defines the timing and storage results of member variables: @ interface ViewController () @ property NSMutableArray * re SultArr; @ property NSTimer * timer; @ property NSDate * beginDate; @ end: set the timer to self. timer = [NSTimer scheduledTimerWithTimeInterval: 0.1 invocation: nil repeats: YES]; set the background color and invisibility of the button: [button setBackgroundColor: [UIColor yellowColor]; [button setEnabled: YES]; statistical time: NSInteger allTime = [_ timer. fireDate timeIntervalSinceDate: _ beginDate]; NSString * timeFormat = [NSString stringWithFormat: @ "% 02ld: % 02ld", allTime/1000, allT Ime % 1000]; [_ timerLabel setText: timeFormat]; judge the result. If all the results are in ascending order, they are successful; otherwise, they fail: // determine whether an array is in ascending order-(BOOL) getArrayAsc :( NSArray *) originalArr {for (NSInteger I = 0; I <[originalArr count]-1; I ++) {if (originalArr [I]> originalArr [I + 1]) {return NO;} return YES;} click events for all buttons:-(IBAction) getResult :( id) sender {UIButton * button = (UIButton *) sender; // set the background color [button setBackgroundColor: [UIColor greenColor]; // button After one click, click [button setEnabled: NO]; NSInteger value = [[[button titleLabel] text] integerValue]; [self. resultArr addObject: [NSNumber numberWithInteger: value]; // click the first button and set the start time if ([self. resultArr count] = 1) {// game start time _ beginDate = [NSDate date]; // game start [_ timer fire];} NSInteger allTime = [_ timer. fireDate timeIntervalSinceDate: _ beginDate]; NSString * timeFormat = [NSString stringWithFormat: @ "% 02ld: % 02ld", al LTime/1000, allTime % 1000]; [_ timerLabel setText: timeFormat]; // call if ([self. resultArr count] = 9) {// destroy the timer [_ timer invalidate]; // The NSString * tip in the pop-up box; if ([self getArrayAsc: self. resultArr]) {tip = @ "congratulations, pass the competition";} else {tip = @ "sorry, the competition failed ";} // concatenate the clicked result with a comma.
