问题 I have a bitmap font which which doesn't have every single character, such as accented characters (é î ü etc) or symbols such as "¥" or © which I'm using to display usernames in a Highscore table for a game. Is it possible to limit the UIKit keyboard to certain characters, or only allow certain characters in the UITextField? Or will I have to roll my own input mechanism? I'm thinking and old school, Arcade style, one letter at a time "thing" would be ok. 回答1: You could try using the following

Set UIKeyboardAppearance across the whole app

由 狂风中的少年 提交于 2019-12-07 06:02:55
问题 Is there a useful property in a cocoa-touch project that would allow setting the one-and-only consistent style of keyboard appearance throughout the app? Say I want UIKeyboardAppearanceAlert on all the textFields and textViews I have in my app without directly modifying anything. Is is possible? 回答1: No, it isn't possible. The keyboardAppearance is part of the UITextInputTraits protocol and is not marked as a UIAppearance method. If it was you could do something like: [[UITextField appearance

UIKeyboard not automatically translucent in iOS7

由 你离开我真会死。 提交于 2019-12-07 05:06:20
问题 I understand that when developing in Xcode 5 with and iOS 7 project, the keyboard that pops up when interacting with a UITextField should be translucent and show through any colors in the background. This is not the case in both my projects. I have a colored & blurred background and I'm hoping for that to transpire through the keyboard; however the keyboard remains the default white/gray. This is what I have so far as a demo: UIColor *tintColor = [UIColor colorWithWhite:0.21 alpha:0.4];

UIKeyboardWillChangeFrame and iPhone X

由 爱⌒轻易说出口 提交于 2019-12-06 14:08:19
问题 Trying with simulator here, and it seems that the frame returned when listening for changes with UIKeyboardWillChangeFrame is incorrect for iPhone X. Specifically the frame seems to be a bit taller than it actually is (visibly) on screen. I'd say the returned frame is about 20 points taller. Did I forget something obvious? Some data... The iPhone X and iPhone 8 have the same width in portrait, which makes it the same height in landscape; 375 points. ( https://www.paintcodeapp.com/news
