Question

我正在为iphone 6和6Plus开发自定义键盘。我已经为shift键激活 - 非激活或123和abc键开发逻辑。但我想显示自定义符号，如显示的苹果键盘。请检入图片。

目前我可以将大写更改为小写，将123更改为abc但是如何设置此特殊字符。注意： - 我在github上搜索了很多演示，但我无法在任何自定义键盘中看到特殊字符。

以下是大写和 ABC-123 按钮的逻辑。

logicalFilter == 1

Answer 1

你需要两个数组，一个用于alphabetical，另一个用于numerical

NSArray *NumKey;

NSArray *arrAlphabet;

现在在NumKey：

NumKey=[[NSArray alloc]initWithObjects:@"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"0", @"-", @"/", @":", @";", @"(", @")", @"$", @"&", @"@", @"\"", @".", @",", @"?", @"!",@"'",@"^", nil];

和arrAlphabet：

 arrAlphabet = [[NSArray alloc]initWithObjects:@"Q", @"W", @"E", @"R", @"T", @"Y", @"U", @"I", @"O", @"P", @"A", @"S", @"D", @"F", @"G", @"H", @"J", @"K", @"L", @"Z", @"X", @"C", @"V", @"B",@"N",@"M", nil];

IBOutlet in keyBoard 123或ABC。

以编程方式添加事件，如下所示。

[self.keybard.btnNumeric addTarget:self action:@selector(action123:) forControlEvents:UIControlEventTouchUpInside];

将123更改为ABC或ABC更改为123

的方法

- (IBAction)action123:(UIButton*)sender
{

    if([self.keybard.btnNumeric.titleLabel.text isEqualToString:@"123"])
    {
        [self.keybard.btnCapital setTitle:@"#+=" forState:UIControlStateNormal];

        [self.keybard.btnNumeric setTitle:@"ABC" forState:UIControlStateNormal];
        int i=0;
        for(UIButton *key in self.keybard.keyArray)
        {
            key.layer.cornerRadius = 6.0;

            [key setTitle:[NumKey objectAtIndex:i] forState:UIControlStateNormal];

            [key addTarget:self action:@selector(pressKey:) forControlEvents:UIControlEventTouchUpInside];
            i++;
        }
    }
    else
    {
        [self.keybard.btnCapital setTitle:@"⬆️" forState:UIControlStateNormal];

        [self.keybard.btnNumeric setTitle:@"123" forState:UIControlStateNormal];

        int i=0;
        for(UIButton *key in self.keybard.keyArray)
        {

            strFirstCap = @"0";

            NSString *uppercaseString = [arrAlphabet objectAtIndex:i];

            [key setTitle:[uppercaseString lowercaseString] forState:UIControlStateNormal];

            [key addTarget:self action:@selector(pressKey:) forControlEvents:UIControlEventTouchUpInside];
            i++;
        }

    }

}

我用这种方式设置了问题，因为我也设置了按键图像。
