如何更改UINavigationBar的标签位置（框架）？

Question

我需要它左对齐。或者没有办法，我需要添加自定义标签？

Answer 1

我发现我自己的解决方案：

float offset = 210.0f; 

UIToolbar* tools = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 0, offset, 44.01)]; 

self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:tools]; 

[tools release]; 

Answer 2

您需要自定义视图添加到导航栏的-titleView

self.navigationItem.titleView = someLabel; 

Answer 3

将它添加到左边的按钮项：

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]; 

Answer 4

我想你可以使用UIBarButtonSystemItemFixedSpace提供增加的一种方式导航栏中的固定填充：

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]; 

This will righ t缩进“取消”按钮50分。
