我需要它左对齐。或者没有办法,我需要添加自定义标签?
答案 0 :(得分:1)
将其添加到左侧按钮项目:
UIView *mCustView = [[UIView alloc] initWithFrame:CGRectMake(0,0,200,20)];
mCustView.backgroundColor = [UIColor redColor];
UILabel *mTextLabel = [[UILabel alloc] initWithFrame:CGRectMake(0,0,200,20)];
mTextLabel.backgroundColor = [UIColor blueColor];
mTextLabel.font = [UIFont systemFontOfSize:20];
mTextLabel.textColor = [UIColor blackColor];
mTextLabel.text = @"Random text tested here, so sit back and enjoy";
[mCustView addSubview:mTextLabel];
[mTextLabel release];
UIBarButtonItem *mCustomBarItem = [[UIBarButtonItem alloc] initWithCustomView:mCustView];
self.navigationItem.leftBarButtonItem = mCustomBarItem;
[mCustView release];

您需要将自定义视图添加到导航栏的-titleView
self.navigationItem.titleView = someLabel;
答案 2 :(得分:0)
我认为你可以使用UIBarButtonSystemItemFixedSpace
提供一种在导航栏中添加固定填充的方法:
UIBarButtonItem *fixedSpaceItem = [[[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace
target:nil
action:NULL]
autorelease];
fixedSpaceItem.width = 50;
UIBarButtonItem *cancelItem = [[[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemCancel
target:nil
action:NULL]
autorelease];
// vc is some view controller
vc.navigationItem.leftBarButtonItems = [NSArray arrayWithObjects:
fixedSpaceItem,
cancelItem,
nil];
这将右键缩进“取消”按钮50分。

我自己找到了解决方案:
float offset = 210.0f;
UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, offset, 44.01)];
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools];
[tools release];
