按钮在iOS6中隐藏文本

Question

I have a text box which has a popover. Also placed a button on top of the text box to make it clickable so that when button is clicked the popover is opened and any item selected will be shown in the text box. This is working fine in iOS7 but in iOS 6 i am able to select the item in popover but the button is hiding the text. Tried setting colour of button but didn't work.

Please help.

Answer 1

If you set the type of the button to "Custom", and you don't set an Image or a Background Image, the button will be invisible on versions prior to iOS7 too.

If you create the button programmatically:

UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];

If you change it on your interface:

Answer 2

Instead of using button, you can open popover by UITextbox itself. Just place the button's IBAction code in textbox's IBAction with EditDidBegin Event.

将iOS 6的UIbutton的按钮类型设置为UIButtonTypeCustom
