源码已经放在github上

左击切换状态，右击显示菜单；但是NSStatusItem没有提供右键菜单，所以要定义自己的View；若果需要直接方便使用的话，有开源框架RHStatusItemView，引入项目中就可以用了。下面是我自己实现的：

//
//  StatusItemView.h
//  awake
//
//  Created by xiaozi on 14-2-21.
//  Copyright (c) 2014年 xiaozi. All rights reserved.
//

#import <Cocoa/Cocoa.h>

@interface StatusItemView : NSControl <NSMenuDelegate>{
    NSImage *_image;
    NSImage *_alternateImage;
    NSStatusItem *_statusItem;
    BOOL _isHighlighted;
    SEL _action;
    SEL _rightAction;
    id __unsafe_unretained _target;
}

@property (nonatomic, readonly) NSStatusItem *statusItem;
@property (nonatomic, strong) NSImage *image;
@property (nonatomic, strong) NSImage *alternateImage;
@property (nonatomic, setter = setHighlighted:) BOOL isHighlighted;
@property (nonatomic) SEL action;
@property (nonatomic) SEL rightAction;
@property (nonatomic, unsafe_unretained) id target;

- (id) initWithStatusItem: (NSStatusItem *) statusItem;

@end

//
//  StatusItemView.m
//  awake
//
//  Created by xiaozi on 14-2-21.
//  Copyright (c) 2014年 xiaozi. All rights reserved.
//

#import "StatusItemView.h"

@implementation StatusItemView

- (id)initWithFrame:(NSRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        // Initialization code here.
    }
    return self;
}

- (void) drawRect:(NSRect)dirtyRect
{
    [_statusItem drawStatusBarBackgroundInRect:dirtyRect withHighlight:_isHighlighted];
    NSImage *icon = _isHighlighted ? _alternateImage : _image;
    NSSize iconSize = [icon size];
    NSRect bounds = [self bounds];
    
    CGFloat iconX = roundf((NSWidth(bounds) - iconSize.width) / 2);
    CGFloat iconY = roundf((NSHeight(bounds) - iconSize.height) / 2);
    NSPoint iconPoint = NSMakePoint(iconX, iconY);
    [icon drawAtPoint:iconPoint fromRect:bounds operation:NSCompositeSourceOver fraction:1.0];
}

- (id) initWithStatusItem: (NSStatusItem *) statusItem {
    CGFloat itemWidth = [statusItem length];
    CGFloat itemHeight = [[NSStatusBar systemStatusBar] thickness];
    NSRect itemRect = NSMakeRect(0.0, 0.0, itemWidth, itemHeight);
    self = [self initWithFrame:itemRect];
    if (self != nil)
    {
        _statusItem = statusItem;
        [_statusItem setView: self];
    }
    return self;
}

- (void)setMenu:(NSMenu *) menu {
    [menu setDelegate: self];
    [super setMenu: menu];
}

- (void)setHighlighted:(BOOL)newFlag
{
    if (_isHighlighted == newFlag) return;
    _isHighlighted = newFlag;
    [self setNeedsDisplay:YES];
}

- (void)mouseDown:(NSEvent *)theEvent
{
    [NSApp sendAction:_action to:_target from:self];
}

- (void)rightMouseDown:(NSEvent *)theEvent
{
    NSMenu *menu = [super menu];
    [_statusItem popUpStatusItemMenu:menu];
    [NSApp sendAction:_rightAction to:_target from:self];
}

- (void)menuWillOpen:(NSMenu *)menu {
    [self setHighlighted:YES];
    [self setNeedsDisplay:YES];
}

- (void)menuDidClose:(NSMenu *)menu {
    [self setHighlighted:NO];
    [self setNeedsDisplay:YES];
}

- (void)setImage:(NSImage *)newImage
{
    _image = newImage;
    [self setNeedsDisplay: YES];
}

- (void)setAlternateImage:(NSImage *)newImage
{
    _alternateImage = newImage;
    if (_isHighlighted)
        [self setNeedsDisplay:YES];
}

- (BOOL)isOpaque
{
    return YES;
}

@end

具体使用方法：

statusItem = [[NSStatusBar systemStatusBar] statusItemWithLength: 22.0];
[statusItem setHighlightMode:YES];
statusView = [[StatusItemView alloc] initWithStatusItem: statusItem];
[statusView setMenu: statusMenu];
// [statusItem setView: statusView];
[statusView setImage: [NSImage imageNamed:@"MenuIcon"]];
[statusView setAlternateImage: [NSImage imageNamed:@"MenuIconSelected"]];

[statusView setAction: @selector(clickStatusItem:)];

cocoa项目中嵌入python

添加链接库：

文件结构：

代码

main.m

#import 
#import 

int main(int argc, char *argv[]) {
    Py_Initialize();
    // 这里面自己定义一个hello函数（python的）好了
    PyRun_SimpleString("import hmac, binascii\n"
                       "from itertools import izip, cycle\n");
    int result = NSApplicationMain(argc, (const char **)argv);
    Py_Finalize();
    return result;
}

控制器里面直接使用就好了

- (IBAction)runpy:(id)sender {
    PyObject *m, *f, *a, *k;

    m = PyImport_ImportModule("__main__");
    f = PyObject_GetAttrString(m, "hello");
    a = PyTuple_Pack(1, PyString_FromString([[_email stringValue] UTF8String]));
    k = PyObject_CallObject(f, a);
    
    // NSLog(@"%@", [NSString stringWithUTF8String:PyString_AsString(k)]);
    [_keycode setStringValue:[NSString stringWithUTF8String:PyString_AsString(k)]];
    
    Py_DECREF(k);
    Py_DECREF(a);
    Py_DECREF(f);
    Py_DECREF(m);
}

写程序时遇到的几个问题，记录一下。

加到project里面的时候不能加在子目录下
编译的时候需要指定JSONKit.m的compiler flags "-fno-objc-arc"

吐槽

object-c的函数长度真心是伤不起的，截图留念！

第一次写object-c程序，写了好几个小时才写出来这么个小东西。

反编译pyc文件，查看算法
写出key生成的算法
将python嵌入Object-C，得到最终的程序

将email和生成的key写入插件目录下的sublime-setting文件。

"email": "your email",
"product_key": "the key",
