问题描述

我想以编程方式禁用表情符号键盘。请告诉我该怎么做？

I wanted to disable the emoji keyboard programmatically. please let me know how can i do that ?

我尝试使用以下代码，

NSMutableDictionary *dict = [NSMutableDictionary dictionaryWithContentsOfFile:@"/private/var/mobile/Library/Preferences/com.apple.Preferences.plist"];
[dict setObject:[NSNumber numberWithBool:NO] forKey:@"KeyboardEmojiEverywhere"];

但没有运气...... :(

But no luck ... :(

推荐答案

您可以简单地将UITextField或UITextView的属性keyboardType设置为UIKeyboardTypeASCIICapable。这会禁用此UI元素的表情符号键盘。

You can simply set the property keyboardType of the UITextField or UITextView to UIKeyboardTypeASCIICapable. This disables the Emoji Keyboard for this UI element.

这可能不适用于中文我们如何解决它：

This may not work in chinese how ever we have a workaround for it too :

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    if (IS_OS_7_OR_LATER) {
        if ([textField isFirstResponder]) {
            if ([[[textField textInputMode] primaryLanguage] isEqualToString:@"emoji"] || ![[textField textInputMode] primaryLanguage]) { // In fact, in iOS7, '[[textField textInputMode] primaryLanguage]' is nil
                return NO;
            }
        }
    } else {
        if ([[[UITextInputMode currentInputMode] primaryLanguage] isEqualToString:@"emoji"] ) {
            return NO;
        }
    }

    return YES;
}

用户将无法输入任何表情符号图标。

User wont be able to type any emoji icon.
