我们如何在导航栏中的UIBarButtonItem中放置两行 [英] How can we put two line in UIBarButtonItem in Navigation Bar
问题描述
正在播放"位于UIBarButtonItem中的一行中.我必须将其放在两行中,例如"Now"位于顶部,"Playing"位于底部.我编写了以下代码行:-
UIBarButtonItem *flipButton = [[UIBarButtonItem alloc]
initWithTitle:@"Now Playing"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(flipView)];
self.navigationItem.rightBarButtonItem = flipButton;
所以我想在"Now Playing"之间打入换行符.所以请帮帮我.
可以.这很简单.创建一个多行按钮并使用它. 技巧"是设置titleLabel numberOfLines属性,使其喜欢多行.
UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
button.titleLabel.numberOfLines = 0;
[button setTitle:NSLocalizedString(@"Now\nPlaying", nil) forState:UIControlStateNormal];
[button sizeToFit];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
当您指定自定义按钮类型时,它会期望您配置所有内容,选定状态等,此处未显示,以使答案集中在当前问题上.
"Now Playing" is in One line in UIBarButtonItem. I have to put it in two lines, like "Now" is ay top and "Playing" is at bottom.I have written the following line of code:-
UIBarButtonItem *flipButton = [[UIBarButtonItem alloc]
initWithTitle:@"Now Playing"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(flipView)];
self.navigationItem.rightBarButtonItem = flipButton;
So i want to pu line break in between "Now Playing". So please help me out.
Yes you can. It is fairly simple to do. Create a multiline button and use that. The "trick" is to set the titleLabel numberOfLines property so that it likes multilines.
UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom];
button.titleLabel.numberOfLines = 0;
[button setTitle:NSLocalizedString(@"Now\nPlaying", nil) forState:UIControlStateNormal];
[button sizeToFit];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:button];
When you specify a button type of custom it expects you to configure everything... selected state, etc. which is not shown here to keep the answer focused to the problem at hand.
