iOS抽奖程序
代码下载地址： http://vdisk.weibo.com/s/HKehU
我们要先写一个数据模型：Model.h
#import <Foundation/Foundation.h> @interface Model : NSObject
@property (strong,nonatomic) NSArray* ClassArray; @end
Model.m代码如下：
#import "Model.h" @implementation Model
@synthesize ClassArray = _ClassArray;
-(id)init
{
if (self = [super init]) {
self.ClassArray = [[NSArray alloc] initWithObjects:@"ddd",@"aaa",@"vvv",@"fff",nil];
}
return self;
}
@end
ViewController.h
#import <UIKit/UIKit.h>
#import "Model.h"
@interface ViewController : UIViewController @property (strong,nonatomic) UILabel* LuckyLabel;
@property (strong,nonatomic) Model* myModel;
@property (strong,nonatomic) NSTimer* TimeController;
@property (strong,nonatomic) UIButton* TimeButton;
@property (assign,nonatomic) BOOL TimeBool;
-(void)StopTime;
-(void)addLabel;
-(void)addModel;
-(void)addTime;
-(void)addButton;
@end
ViewController.m
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
TimeBool = YES; UIImageView* backImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"002.png"]]; backImageView.frame = CGRectMake(0, 0, 768, 1024);
[self.view addSubview:backImageView];
[self addLabel]; [self addButton]; }
添加标签
-(void)addLabel
{
self.LuckyLabel = [[UILabel alloc] initWithFrame:CGRectMake(300, 200, 260, 200)];
[self.LuckyLabel setFont:[UIFont fontWithName:@"Verdana" size:63]];
self.LuckyLabel.backgroundColor = [UIColor clearColor];
self.LuckyLabel.textAlignment= UITextAlignmentCenter;
[self.view addSubview:self.LuckyLabel];
UILabel* Title = [[UILabel alloc] initWithFrame:CGRectMake(200, 20, 350, 200)];
Title.backgroundColor = [UIColor clearColor];
Title.textAlignment = UITextAlignmentCenter;
[Title setFont:[UIFont fontWithName:@"Verdana" size:30]];
Title.text = @"幸运大抽奖";
[self.view addSubview:Title];
UILabel* NameLabel = [[UILabel alloc] initWithFrame:CGRectMake(40, 200, 260, 200)];
NameLabel.textAlignment = UITextAlignmentCenter;
[NameLabel setFont:[UIFont fontWithName:@"Verdana" size:50]];
NameLabel.backgroundColor = [UIColor clearColor]; NameLabel.text = @"幸运学生：";
[self.view addSubview:NameLabel]; }
添加模型数据
-(void)addModel
{
if (m_pInt ==self.myModel.ClassArray.count) {
m_pInt = 0;
} self.LuckyLabel.text = [self.myModel.ClassArray objectAtIndex:m_pInt];
m_pInt++; }
添加定时器
-(void)addTime
{
self.TimeController = [NSTimer scheduledTimerWithTimeInterval:0.01 target:self selector:@selector(addModel) userInfo:nil repeats:YES];
}
添加按钮
-(void)addButton
{
self.myModel = [[Model alloc] init];
self.TimeButton = [UIButton buttonWithType:UIButtonTypeCustom];
self.TimeButton.frame = CGRectMake(266, 800, 200, 100);
[self.TimeButton setTitle:@"开始抽奖" forState:UIControlStateNormal];
self.TimeButton.titleLabel.textAlignment = UITextAlignmentCenter;
[self.TimeButton.titleLabel setFont:[UIFont fontWithName:@"Verdana" size:35]];
[self.TimeButton addTarget:self action:@selector(StopTime) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:self.TimeButton];
}
暂停方法
-(void)StopTime
{
if (TimeBool) {
[self addTime];
TimeBool = NO;
[self.TimeButton setTitle:@"停止" forState:UIControlStateNormal]; }
else{
//Time停止
[self.TimeController invalidate];
TimeBool = YES;
[self.TimeButton setTitle:@"开始抽奖" forState:UIControlStateNormal];
}
}
