> The above code is designed to achieve the following effects:
> Step1. When the focus in the input1, the ipad automatically display soft 
> keyboard (It's should be iOS default function, focus on the input box will 
> automatically eject the soft keyboard)
>  [The ScreenShot of Step1|https://i.stack.imgur.com/kC96b.png]
> Step2. When we enter content in input1, it will show alert warning if it 
> found that the input is not "abc" when the input1 lose focus (implemented in 
> the onblur event)
>  [The ScreenShot of Step2|https://i.stack.imgur.com/uEuSi.png]
> Step3. At the same time , the background color of the input1 will be changed 
> to red, and let the focus return to the input1 and automatically display the 
> soft keyboard again
>  [The ScreenShot of Step3|https://i.stack.imgur.com/tHqNb.png]
> Our problem is, at the Step2, we can make input1 lose focus in two ways(The 
> Pattern1 and The Pattern2):
> Pattern1. Use mouse to click input2
> Pattern2. Press the button in the lower right corner of the soft keyboard to 
> put the keyboard away
>  [The ScreenShot of the button|https://i.stack.imgur.com/NY1AN.png]
> At present, when we operate by Pattern1, there is no problem, the Step3 can 
> be expected to show the effect.
> But when we operate by Pattern2, when by calling the focus() method to make 
> input1 get the focus, soft keyboard will flash (appear, and immediately 
> disappear), tried a lot of ways to keep the soft keyboard always appear, we 
> already took 2, 3 days to try to solve the problem, are not done. Do not know 
> whether need to modify InAppBrowser's Objective-C code? Please tell us how to 
> solve the problem. Thank you very much.
