 2 | JKCountDownLable,子类化UILable实现iOS倒计时Lable,天,时,分,秒
 3 | 
 4 | ## 代码方式使用
 5 |     
 6 |     JKCountDownLable *_countDownCode;
 7 |     _countDownCode = [JKCountDownLable alloc]initWithFrame: CGRectMake(81, 200, 108, 32)];
 8 |     [self.view addSubview:_countDownCode];
 9 | 
10 |      //设置最原始的text
11 |      _countDownCode.text  = @"00 : 00 : 00";
12 | 
13 |     //[_countDownCode countDownWithDate:[NSDate dateWithTimeIntervalSinceNow:864000]];
14 |     
15 |     [_countDownCode countDownWithTimeInterval:1470614888];
16 |  
17 |      [_countDownCode countDownLableChange:^NSString *(JKCountDownLable *countDownLable, NSDate *endTime, NSTimeInterval second,NSDictionary *DHMSInfo, NSString *defaultText) {
18 |         
19 |         //自己格式化
20 |         NSInteger D = [[DHMSInfo objectForKey:@"D"] integerValue];
21 |         NSInteger H = [[DHMSInfo objectForKey:@"H"] integerValue];
22 |         NSInteger M = [[DHMSInfo objectForKey:@"M"] integerValue];
23 |         NSInteger S = [[DHMSInfo objectForKey:@"S"] integerValue];
24 |         
25 |         return [NSString stringWithFormat:@"%0.2zd : %0.2zd : %0.2zd", H,M,S];
26 | 
27 |          //使用控件内的默认格式化后的文本
28 |         //return defaultText;
29 |     }];
30 |      [_countDownCode countDownLableFinished:^NSString *(JKCountDownLable *countDownLable, NSDate *endTime, NSTimeInterval seconds, NSDictionary *DHMSInfo, NSString *defaultText) {
31 |         //自定义倒计时结束标题
32 |         return @"00 : 00 : 00";
33 |         //使用控件内的默认格式化后的文本
34 |         //return defaultText;
35 |     }];
36 | 
37 | ## xib方式使用
38 | 
39 |     @property (weak, nonatomic) IBOutlet JKCountDownLable *countDownXib;
40 | 
41 |       //设置最原始的text
42 |      self.countDownXib.text  = @"00 : 00 : 00";
43 |      [self.countDownXib countDownWithDate:[NSDate dateWithTimeIntervalSinceNow:864000]];
44 |     
45 |     //[self.countDownXib countDownWithTimeInterval:1470614888];
46 |     
47 |       [self.countDownXib  countDownLableChange:^NSString *(JKCountDownLable *countDownLable, NSDate *endTime, NSTimeInterval second,NSDictionary *DHMSInfo, NSString *defaultText) {
48 |             
49 |             //自己格式化
50 |             NSInteger D = [[DHMSInfo objectForKey:@"D"] integerValue];
51 |             NSInteger H = [[DHMSInfo objectForKey:@"H"] integerValue];
52 |             NSInteger M = [[DHMSInfo objectForKey:@"M"] integerValue];
53 |             NSInteger S = [[DHMSInfo objectForKey:@"S"] integerValue];
54 |             
55 |             return [NSString stringWithFormat:@"%0.2zd : %0.2zd : %0.2zd", H,M,S];
56 | 
57 |     //        //使用控件内的默认格式化后的文本
58 |     //        return defaultText;
59 |         }];
60 |      [self.countDownXib countDownLableFinished:^NSString *(JKCountDownLable *countDownLable, NSDate *endTime, NSTimeInterval seconds, NSDictionary *DHMSInfo, NSString *defaultText) {
61 |         //自定义倒计时结束标题
62 |         return @"00 : 00 : 00";
63 |         //使用控件内的默认格式化后的文本
64 |         //return defaultText;
65 |     }];
