Mac os 文件复制

第一次做mac os应用捉襟见肘，之前都是在写iOS。如果还和刚开始自学iOS的时候写HelloWorld，感觉有点low。于是从模仿开始。下面开始着手写一个文件复制的小栗子。
这里写图片描述
就是这样一个例子

首先创建项目，创建项目的时候不去勾选Use Storyboards这个选项，这时候就会创建一个不带storyboards的项目。这时候进入到MainMenu.xib中把window删掉。
创建一个继承自NSWindowController的windowController并且带xib。这时候就可以去AppDelegate中去撸代码了。
在AppDelegate中首先导入创建的windowController，并且声明一个变量。

#import <Cocoa/Cocoa.h>#import "MainWindowController.h"@interface AppDelegate : NSObject <NSApplicationDelegate>@property (nonatomic, strong)MainWindowController *mainWindow;@end

在.h中创建完之后，进入到.m文件中进行操作

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification {    // Insert code here to initialize your application    self.mainWindow = [[MainWindowController alloc]initWithWindowNibName:@"MainWindowController"];    [[self.mainWindow window]center];    [self.mainWindow.window orderFront:nil];}

这是后可以运行xcode，你可以在创建的xib中拖一个控件，这是就可以看到窗口出现了。
接下来就是自创的MainWindowController中进行文件操作，图片上的控件是拖到MainWindowController.xib上的。这是对这些控件绑定事件。

#import <Cocoa/Cocoa.h>@interface MainWindowController : NSWindowController{    NSFileManager *fm; // NSFileManager    NSMutableDictionary *dicPath; //可变字典    dispatch_semaphore_t semaphore; // 信号量控制并发}@end

#import "MainWindowController.h"#import "AFNTool.h"@interface MainWindowController ()@property (strong) IBOutlet NSTextField *userName;@property (strong) IBOutlet NSTextField *passWord;@property (strong) IBOutlet NSProgressIndicator *progress;@end@implementation MainWindowController- (void)windowDidLoad {    [super windowDidLoad];    self.window.title = @"登录";    dicPath = [NSMutableDictionary dictionaryWithCapacity:2];    semaphore=dispatch_semaphore_create(1);    self.progress.hidden = YES;}// 选取文件路径- (IBAction)LoginButton:(NSButton *)sender {    dispatch_async(dispatch_get_main_queue(), ^{        @autoreleasepool {            fm = [NSFileManager defaultManager];            NSOpenPanel *oPanel = [NSOpenPanel openPanel];            [oPanel setCanChooseDirectories:YES];            [oPanel setCanChooseFiles:YES];            if ([oPanel runModal] == NSOKButton) {                NSString *str =[[[oPanel URLs] objectAtIndex:0] path];                [dicPath setValue:str forKey:@"copyPath"];                [self.userName setStringValue:str];                NSLog(@"OK");            }else{                NSLog(@"Cancel");            }        }    });}// 存放文件路径- (IBAction)paseFile:(NSButton *)sender {    dispatch_async(dispatch_get_main_queue(), ^{        @autoreleasepool {            NSOpenPanel *oPanel = [NSOpenPanel openPanel];            [oPanel setCanChooseDirectories:YES];            [oPanel setCanChooseFiles:NO];            if ([oPanel runModal] == NSOKButton) {  //如果用户点OK                NSString *str =[[[oPanel URLs] objectAtIndex:0] path];                [dicPath setValue:str forKey:@"pastePath"];                [self.passWord setStringValue:str];                NSLog(@"OK");            }else{                NSLog(@"Cancel");            }        }    });}// 复制文件路径- (IBAction)copyButton:(NSButton *)sender {    self.progress.hidden = NO;    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT,0),^{        dispatch_semaphore_wait(semaphore,DISPATCH_TIME_FOREVER);        dispatch_async(dispatch_get_main_queue(), ^{            [self.progress startAnimation:nil];        });        [self copyFileToPath];        dispatch_semaphore_signal(semaphore);        dispatch_async(dispatch_get_main_queue(), ^{            [self.progress stopAnimation:nil];            self.progress.hidden = YES;        });    });}-(void)copyFileToPath{    NSString *str = [dicPath objectForKey:@"copyPath"];    NSArray *arrFileName =[str componentsSeparatedByString:NSLocalizedString(@"/", nil)];    NSString *pasteStr = [[[dicPath objectForKey:@"pastePath"] stringByAppendingString:@"/"] stringByAppendingString:[arrFileName lastObject]];    BOOL isDir = NO;    NSError* error=nil;    BOOL existed = [fm fileExistsAtPath:pasteStr isDirectory:&isDir];    if ( !(isDir == YES && existed == YES) )    {        [fm removeItemAtPath:pasteStr error:nil];    }    [fm copyItemAtPath:[dicPath objectForKey:@"copyPath"] toPath:pasteStr error:&error];    if (error!=nil) {        NSLog(@"%@", error);        NSLog(@"%@", [error userInfo]);    }    //    [dicPath removeAllObjects];}@end

代码可以直接粘贴过去。这时候就可以做简单的文件复制了。缺点对压缩的文件不能操作。希望大神给予指点一二。
