Question

Answer 1

Better you can use PickerView Frame like this,

    Pickerview.frame = CGRectMake(30,100,170,200);

Answer 2

You can not. UIPickerViewcan display 5 lines or 3 lines, depending on the height of the frame that you pass to the method -setFrame:. When I need a short one UIPickerView, I will pass a height of 100. The code in UIKit will adjust this height as the closest possible value.

:

UIView 170 55.

subviews = YES

UIPickerView UIView. 0, -80.5.

UIImageView 170, 55 UIView. , .

(You can resize the image and make it stretch to resize it horizontally)

The final result:

Answer 4

Have you tried to implement numberOfRowsInComponent:? If this does not change the size, have you tried to set the selection frame?

ps: I agree with @Ritheesh @BoltClock, one line is not a good idea
