[英]adding notification badge to Navigation bar in iOS
I'm trying to add a badge to the navigation bar of my iOS app,more precisely to the Menu button which triggers my side menu. 我正在尝试将徽章添加到我的iOS应用程序的导航栏中,更确切地说是添加到触发我的侧菜单的“菜单”按钮。 I'm using this code 我正在使用此代码
// add badge to the menu button
if (!self.numberBadge) {
self.numberBadge = [[MLPAccessoryBadgeEmboss alloc] initWithFrame:CGRectZero];
}
numberBadge.center = CGPointMake(30.0, 6);
numberBadge.badgeMinimumSize = CGSizeMake(1.0, 1.0);
numberBadge.backgroundColor = [UIColor redColor];
numberBadge.shadowAlpha = 0.9;
numberBadge.cornerRadius = 5.0f;
numberBadge.strokeColor = [UIColor whiteColor];
[self.navigationController.navigationBar addSubview:numberBadge];
[numberBadge setTextWithIntegerValue:9];
as result, the badge gets displayed like that: 结果,徽章显示为:
now I've been trying both modifying the frame and the centre of the badge uiview but, no matter what I do, it will stick to the upper-left corner of the navigation bar. 现在,我一直在尝试同时修改框架和徽章uiview的中心,但是,不管我做什么,它都将粘贴在导航栏的左上角。 It's currently impossible for me to move it. 我目前无法移动它。
Any suggestions? 有什么建议么?
It looks like your badge is always positioned at (0, 0) in the navigation bar. 您的徽章似乎始终位于导航栏中的(0,0)。
I assume that when you assign self.numberBadge, you are assigning it to an instance variable called numberBadge, otherwise you would had to use self.numberBadge instead. 我假设当您分配self.numberBadge时,是将其分配给一个名为numberBadge的实例变量,否则您将不得不使用self.numberBadge。
I would try these things: 我会尝试这些事情:
If it still doesn't work, can you try adding the badge to a plain UIView and check if it works there? 如果仍然无法使用,您可以尝试将徽章添加到普通的UIView并检查它是否可以在那里工作吗?
