UIPickerView UI and Functional issue in iPhone 6s plus device

Question

I have created custom TimePicker using UIPickerView, taken 3 UIPickerView.

• One for Hours
• One for Minutes
• One for AM/PM

By picking time, I am using that time to set local notification. Because my application is based on alarm functionality.

UI part and Functional part works well in iPhone 5,5s,6,6 Plus but facing issue in iPhone 6s plus device. Not getting what is going wrong! Same code works well in all other devices except iPhone 6s plus.

Below screenshot is of iPhone 6,

As you can see, ScreenShot time and PickerView time is same. It is functional part. I have written code like, catch the current time and as per that I have set the PickerView's selected index. Works perfect! Also I have set selected index fonts bigger. Which is also looks perfect in iPhone 6 device.

Below screenshot is of iPhone 6s Plus,

As you can see, ScreenShot time and PickerView time is not same. So functional part is not working in iPhone 6s plus device. Also in UI part, Fonts getting bigger for selected row in second PickerView but not in the first one.

Also when I set the local notification by picking time from time picker. It also works well (Notification gets fire on perfect time) in all other devices other than iPhone 6s plus. And in iPhone 6s plus whatever time I select from UIPickerView, notification gets fire immediately.

Don't know what is going wrong with iPhone 6s plus device. Either issue is with PickerView or something else. But why the same code works well for all other device and not only for iPhone 6s plus device.

Any help is appreciated! Badly stuck in this issue. Please help if anyone have any solution for this issue! Thanks in advance.

UPDATE :

Please have a look in to my code...

Seems like there is something wrong with the autolayout, if you are using that. Is there a constraint missing or extra? You could set the background color for the textfield to see if the font is smaller, or the whole view. – Vickievicksburg

No, I am not using autolayout. I had managed it using Auto resizing. And there is not only UI issue. Facing functional issue as well in iPhone 6s plus. – Crave

iPhone 6s plus is device or simulator? And running which ios ? And other devices or simulator which works fine are running wich ios? – Folly

Can you show your storyboard. – Chronology

No, I can't show full storyboard. – Crave

You could look at environmental factors... maybe it has something to do with the Locale of the 6s device? Did you already try another 6s device to see if it has the same issue, so you can isolate factors. – Vickievicksburg

Could also be interesting to have a look at your code anyway. Can you post the bit where you update these elements? – Vickievicksburg

Why can't you show the storyboard? Right now you're just asking a question with images and no code. It's impossible for us to know what is going on without more context. If you can't show the storyboard or any code, please post or upload a standalone MCVE or sample project which reproduces the issue. – Hixon

@JorisvanLiempdiDeveloper Please check my updated question. I have added whole code which I have written for Custom Time Picker(As in attached image) – Crave

Answer 1

This answer is for future readers, may be it will help someone somehow.

After doing a lot R & D and debugging the code, finally resolved my issue.

Code which I added in my current(check code of above question) code is as below,

NSLocale *locale = [NSLocale localeWithLocaleIdentifier:@"en_US_POSIX"];
NSDateFormatter *format = [[NSDateFormatter alloc] init];
[format setLocale:locale];
[format setTimeZone:[NSTimeZone systemTimeZone]];

Before adding above lines of code(added these lines where ever I have used NSDateFormatter) it was working fine in all other devices except iPhone 6s plus. But by setting NSLocale and TimeZone to NSDateFormatter it is working perfectly fine in ALL devices.

Thanks!
