给你的iphone应用程序图标加上个红色徽标

1. 有些app收到post notification时会显示一个红色的微标, 很简单:

- (void)applicationWillResignActive:(UIApplication *)application {

application.applicationIconBadgeNumber = 10;

}

这样的你的图标会加上一个红色10的标志.

2. 给我们的文本弹出式菜单加上自己的内容.

UIMenuItem *item = [[UIMenuItem alloc] initWithTitle:@"Open url in safari" action:@selector(openURLInSafari:)];

[[UIMenuController sharedMenuController] setMenuItems:[NSArray arrayWithObject:item]];

[item release];

但是要注意, 我们想让用户选择了可被safari识别的链接时才打开这个链接. 这样做:

- (BOOL)canPerformAction:(SEL)action withSender:(id)sender

{

if (action == @selector(openURLInSafari:))

{

NSString *selectedString = [self._txtView.text substringWithRange:self._txtView.selectedRange];

NSURL *url = [NSURL URLWithString:selectedString];

return [[UIApplication sharedApplication] canOpenURL:url];

}

return [super canPerformAction:action withSender:sender];

}

Yes, that's it!
