Continuing the answer by Dave DeLong I got it working like this......

In <code>viewDidLoad</code> i did this...

<pre><code> CGRect frame = horizontalPickerView.frame;
 frame.size.width = 50;
 frame.size.height = 216;
 frame.origin.x=90;
 frame.origin.y = 200;
 horizontalPickerView.frame = frame;

 horizontalPickerView.transform = CGAffineTransformMakeRotation(3.14159/2); 






- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
 UILabel *lbl = [[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 30, 20)] autorelease];
 lbl.transform = CGAffineTransformMakeRotation(-3.14159/2);
 lbl.text = @"hi";
 return lbl;
 }
</code></pre>

Hope this helps

blocks|key|3276126|text|您可以通过以下方式完成此操作:获取常规UIPickerView，调整其宽度(通过setFrame:)，然后应用NSAffineTransform将其旋转90度。然后，您需要将拾取器中的每个项目以另一种方式旋转90°。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3276127|正确地做这件事有点单调乏味，但它是可以做到的。|3276128|entityMap^0|14|9|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

You can do this by taking a regular UIPickerView, adjusting its width (via <code>setFrame:</code>), and then applying an NSAffineTransform to rotate it 90º. You'll then need to rotate each item in the picker 90º the other way.

It's a little tedious to do it properly, but it can be done.

blocks|key|343870|text|当我搜索水平UIPickerView时，@Madhup的代码将我引导到我想要的大致方向，但是我意识到提出的问题并没有真正得到解决，所以对于正在寻找从左到右旋转的更合适答案的人来说。我读过的答案中的代码都是为了支持从左向右滑动，导致选取器将具有较高值的标签/行推到视图的左侧。无论如何，这是我的贡献：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|343871|在viewDidLoad方法中：|343872|++++yourPickerView.frame+=+frame;

@Madhup's code lead me in the general direction I wanted when I searched for the horizontal <code>UIPickerView</code> but I then realized the question asked wasn't really addressed so for anyone who was looking for a more suitable answer to the left-to-right rotation. The code in the answers I'd read were all to enable left-to-right swiping, causing the picker to push the labels/rows with higher values to the left of the view. Any ways here's my contribution:

In the <code>viewDidLoad</code> method:

<pre><code> yourPickerView.frame = frame;
 yourPickerView.transform = CGAffineTransformMakeRotation(4.71238898); //Instead of rotating clockwise 90° we're rotating 90° counterclockwise. 4.71238898 being ≈270° in radians.
 [self.view addSubview:self.picker];
 self.yourPickerView.delegate = self;
 self.yourPickerView.dataSource = self;
 self.yourPickerView.showsSelectionIndicator = YES;
 self.yourPickerView.userInteractionEnabled = YES;
</code></pre>

The <code>pickerView</code>'s method:

<pre><code> -(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view{
 UILabel *label = [[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 20, 20)] autorelease];
 yourLabel.transform = CGAffineTransformMakeRotation(1.57079633); //Instead of rotating counterclockwise 90° we're rotating 90° clockwise 1.57079633 being ≈90° in radians.
 yourLabel.font = [UIFont fontWithName:@"System-Bold" size:18]; //Your font here.
 yourLabel.text = @"yourLabel's text"; //or like me [NSString stringWithFormat:@"%@, [yourArray objectAtIndex:row]]
 yourLabel.backgroundColor = [UIColor clearColor];
 return label;
 }
</code></pre>

blocks|key|346404|text|尝试在分页滚动视图中每页显示一个项目，如果您希望控件具有更好的图形，并且只允许水平滚动(不要使滚动视图的contentSize比实际视图的大小更高，并禁用控件上的垂直滚动反弹)，则可以在其上方覆盖图像。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|346405|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Try a paged scrollview that has the items you want on one per page, and perhaps overlay an image above it if you want nicer graphics for your control, and only allow for horizontal scrolling (don't make the contentSize of the scrollview taller than the size of the actual view, and disable vertical scroll bouncing on the control).

Try this->
Create Plain UIVew of size of UIPickerview, add picker on it.
set numberOfComponentsInPickerView = 1.
set componant width.
Then add small sub views on it to Hide rest of picker. Only rotating wheel of componant should visible.
Transform plain view to rotate it through 90 degree.

Make sure to apply tranform in:

<pre><code>-(UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component reusingView:(UIView *)view 

{

 UILabel *lbl = nil;
 if(view)
 {
 lbl = (UILabel *) [view viewWithTag:11];
 }
 else
 {
 view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 32, 32)];
 lbl = [[UILabel alloc] initWithFrame:CGRectMake(1, 0, 30, 30)];
 lbl.tag = 11;
 lbl.backgroundColor = [UIColor clearColor];
 lbl.textAlignment = UITextAlignmentCenter;
 lbl.font = [UIFont fontWithName:@"Helvetica-Bold" size:18];
 lbl.transform = CGAffineTransformRotate(lbl.transform, M_PI +M_PI/2);
 [view addSubview:lbl];
 [lbl release];
 }


 lbl.text = [dataSourceArray objectAtIndex:row];


 return view;
}
</code></pre>

Now you can add palin view as a subview for horizontal picker on any view.

You will have to create picker programitcally, so that you can create your own sized picker with <code>CGRectMake(x, y, width, height)</code> then, you will have to rotate it, but rotating it will also rotate in the Picker's dataSources methods, you will have to rotate the view inverse of picker's rotation, I am including code hopfully it will help

<pre><code>.....

 radiusDefaults = [[NSMutableArray alloc] initWithArray:arr] ;

 radiusPicker = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 0, 100, 150)];
 radiusPicker.delegate = self;
 radiusPicker.dataSource = self;
 radiusPicker.showsSelectionIndicator = NO; 

 //Resize the picker, rotate it so that it is horizontal and set its position
 CGAffineTransform rotate = CGAffineTransformMakeRotation(-1.57); 
 rotate = CGAffineTransformScale(rotate, .1, .5);
 CGAffineTransform t0 = CGAffineTransformMakeTranslation(-61, 0);
 radiusPicker.transform = CGAffineTransformConcat(rotate,t0);

// [theNavigationBar.topItem setTitleView:radiusPicker] ;

Have you ever considered taking a table view and rotating it? 

Didn't think so. Go try that. :)

I've only seen it in a VERY few iPhone apps... but it looks like a picker that rotates left/right (instead of top/bottom).

They usually put it on 1 line of a tableView... to allow the user to quickly pick between a small number of choices (like 3-10).

How is that coded?

An iphone uipickerview that rotates horizontally?

我只在很少的几个iPhone应用程序中看到过它。但它看起来像一个向左/向右旋转的选择器(而不是顶部/底部)。他们通常把它放在tableView的一行上...允许用户在少量选项(如3-10个)之间快速选择。这是怎么编码的？
