第一个Mac程序——倒计时v1&v2

先放效果图:

这是我第一次尝试在Mac平台下编程,之前学过几天IOS开发,一直在等MJ老师更新。闲下来不编程不舒服,给自己,也给老婆编了这个以提醒自己好好学习。v2版加入了各种倒计时。改进了界面。把倒计时计算抽成了一个类,提高程序的复用性。



-概览

首先放上xib界面图

-改界面名字

建项目的过程中一开始不小心取了个没有远见的名字“考研倒计时”,后来改成了倒计时。怎么改呢?我是这样改的:(比如程序的window,上面的menuitem类同)

顺手把Resize的钩钩去掉

把Full Screen改成Primary Window蛮有意思的。(试试把Resize勾上再全屏)

 

 

-拖入控件

这里我一开始只拖进去这5句话(NSTextField),双击控件先把文字改个样子做个效果。在右边顺便把字体改了。

后来如图又加入了一个NSImageView 以作背景

在Attribute Inspector中改成我事先找好的图,并把Scaling改成AxesIndependently 这样图片就可以适当的放缩了。

 

 

-代码&优化

一开始我的代码是这样的,后来又加了纪念日、软考等,代码是直接“拷贝”复用的。

#pragma mark - 设置 -
NSDateComponents *components=[[NSDateComponents alloc]init];//创建组件
  
#pragma mark 考研
      [components setMonth:1];
      [components setDay:4];
      [components setYear:2015];
      [components setHour:7];
      NSDate *targetDate = [[NSCalendar currentCalendar] dateFromComponents:components];
      NSTimeInterval targetInteval = [targetDate timeIntervalSinceNow];
    // NSLog(@"%f",KYinteval);
    NSLog(@"%d",(int)targetInteval/60/60/24);
    [_KYLabel setStringValue:[NSString stringWithFormat:@"距离考研还有%d天!",(int)targetInteval/60/60/24]];


v2版把倒计时计算抽成了一个类,提高程序的复用性。

用法如下:(使用了Delegate思想和静态实例化思想)

ZZYDateCounter*dc=[ZZYDateCounter CounterWithTargetYear:2015mounth:1day:4hour:7andSentence:@"距离考研还有%d天!"];
    dc.textDelegate=_KYLabel;
    [dc say];

ZZYDateCounter源代码如下:(提供了使用NSDate初始化和直接使用年月日小时直接初始化的两个接口,为以后的扩展预留接口)

    return [counter initWithYear:y mounth:m day:d hour:h andSentence:targetSentence];
     }
@end

 

在AppDelegate中添加下面两个方法:

//关闭Window后退出程序
-(BOOL)applicationShouldTerminateAfterLastWindowClosed:(NSApplication *)sender{
    NSLog(@"ttt");
    returnYES;
}
 //当然少不了彩蛋了!
- (IBAction)onAboutClicked:(NSMenuItem *)sender {
    NSAlert *alert = [NSAlertalertWithMessageText:@"关于这个软件"defaultButton:@"我也爱你" alternateButton:nilotherButton:nilinformativeTextWithFormat:@"为我家亲爱的编写,祝我们都能考上好研究生,一辈子在一起!\n永远爱我家文儿!"];
    [alert beginSheetModalForWindow:_windowcompletionHandler:nil];
 
}

最后,别忘了Screen Shot 2014 03 14 at 5 08 58 PM

设置为开机自启:)

 

 

心得体会:

Mac下开发果然特别舒服,和IOS一脉相承。了解了NSImageView和NSTextView和NSWindow 等控件。

计划以后继续深入了解如:

改变部分字体颜色和文字大小、

改进NSWindow的外观、

使用快捷键进出全屏

等。

还有,感觉排版很渣。。。MarsEdit还不是很熟。。继续努力!
