iPhone-将UISegmentedControl添加到导航控制器工具栏 [英] iPhone - adding a UISegmentedControl to a Navigation Controller Toolbar

问题描述

将UISegmentedControl添加到导航控制器工具栏是否是一个异端?

Is this an heresy to add a UISegmentedControl to a navigation Controller Toolbar?

我正在考虑以下代码:

UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:
                                            [NSArray arrayWithObjects:
[NSString stringWithString:NSLocalizedString(@"One", @"")],
[NSString stringWithString:NSLocalizedString(@"Two", @"")],
[NSString stringWithString:NSLocalizedString(@"Three", @"")],
[NSString stringWithString:NSLocalizedString(@"Four", @"")],
nil]];

segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
segmentedControl.tintColor = [UIColor blackColor];

[segmentedControl setSelectedSegmentIndex:0];


[segmentedControl addTarget:self action:@selector(changeSegment:) 
               forControlEvents:UIControlEventValueChanged];

[segmentedControl setFrame:[self.navigationController.toolbar bounds]];

[self.navigationController.toolbar addSubview:segmentedControl];
[segmentedControl release];

我已经尝试过此代码，并且触摸这些段似乎没有选中该段.

I have tried this code and the segments don't appear to be selected with I touch them.

这是正确的方法吗?

谢谢.

推荐答案

这很可能是由于您的tintColor是黑色的.更改颜色，您应该可以看到所选的片段.

This is most likely due to your tintColor being black. Change the color and you should see the selected segment reflected.
