AppKit 一点笔记(二)

NSApplicationDelegate

实现

- (NSMenu *)applicationDockMenu:(NSApplication *)sender

{

    return _menu;

}

2 状态条菜单

  需要NSMenuDelegate protocol

@protocol NSMenuDelegate <NSObject>

@optional

- (void)menuNeedsUpdate:(NSMenu*)menu;

- (NSInteger)numberOfItemsInMenu:(NSMenu*)menu;

- (BOOL)menu:(NSMenu*)menu updateItem:(NSMenuItem*)item atIndex:(NSInteger)index shouldCancel:(BOOL)shouldCancel;

给StatusBar加Icon

- (void)activateStatusMenu:(int)status

{

    NSStatusBar *bar = [NSStatusBar systemStatusBar];

    icon = [bar statusItemWithLength:NSVariableStatusItemLength];

    [icon retain];

NSString* filePath;

switch (status) {

case 0:

filePath = [[NSBundle mainBundle] pathForResource:@"sync_complete" ofType:@"png"];

break;

case 1:

filePath = [[NSBundle mainBundle] pathForResource:@"sync_processing" ofType:@"png"];

break;

case 2:

filePath = [[NSBundle mainBundle] pathForResource:@"sync_error" ofType:@"png"];

break;

default:

break;

}

NSImage* image = [[NSImage alloc] initWithContentsOfFile:filePath];

[icon setImage:image];

[icon setHighlightMode:YES];

[icon setMenu:mainMenu];

}

关于菜单就讲这么多
