看到此等app开发从业者，也挺无语的

看到这样的代码，也不好意思说她们不是程序猿
唯一想到的是：
哦！原来北大青鸟是这么教的！
(1个弹出打开和保存文档，对话框的osx实现方法)

- (IBAction)OnBT_OpenSaveDialog:(id)sender{   // File : no 扩展名   // NSSavePanel *savePanel = [NSSavePanel savePanel];   // [savePanel runModal];    NSSavePanel*    panel = [NSSavePanel savePanel];    NSView *viewExt = [[NSView alloc] initWithFrame:NSMakeRect(0, 0, 180, 40)];    NSTextField *labExt = [[NSTextField alloc] initWithFrame:NSMakeRect(0, 10, 80, 20)];    [labExt setBordered:NO];    [labExt setDrawsBackground:NO];    labExt.stringValue = @"File type: ";    NSComboBox *cbExt = [[NSComboBox alloc] initWithFrame:NSMakeRect(80, 8, 100, 25)];    //[cbExt addItemsWithObjectValues:@[@".bmp", @".jpg", @".png", @".tif"]];    [cbExt addItemsWithObjectValues:@[@".txt"]];    cbExt.stringValue = @".txt";    [viewExt addSubview:labExt];    [viewExt addSubview:cbExt];    [panel setAccessoryView:viewExt];    NSInteger result = [panel runModal];    if (result == NSFileHandlingPanelOKButton)    {        NSString *path = [[panel URL] path];        NSLog(path);    }}//ok!- (IBAction)OnBT_OpenSelectedDialog:(id)sender{    NSOpenPanel *panel = [NSOpenPanel openPanel];    [panel setMessage:@""];    [panel setPrompt:@"OK"];    [panel setCanChooseDirectories:YES];    [panel setCanCreateDirectories:YES];    [panel setCanChooseFiles:YES];    NSString *path_all;    NSInteger result = [panel runModal];    if (result == NSFileHandlingPanelOKButton)    {        path_all = [[panel URL] path];        NSLog(path_all);    }}//test OK！

很9之前一个ios全栈程序猿和我说： mac的精髓在拖拉，和windows完全不同
不能更同意了
我觉得还有animate吧，感觉是挺优雅的，更人性
（他拥有iphone2～iphone5全系列，mac，pad, mac mini，反正就是出1个就买1个，真正用的人才更懂如何写程序）
