【问题描述】：
我正在为 iphone 6 和 6Plus 开发自定义键盘。我已经开发了 shift key active-inactive 或 123 和 abc key 的逻辑。但我还想显示自定义符号，如显示的苹果键盘。请查看图片。
目前我可以将大写更改为小写，将 123 更改为 abc，但我该如何设置这个特殊字符。 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。
这是我对 大写 和 ABC-123 按钮的逻辑。
-(void)UpparCase:(UIButton*)sender // To make caps or small letter
{
sender.selected=!sender.selected;
if(sender.selected)
{
if(isPortrait)
{
[self.ObjKeyLayout.btnCapKey setBackgroundImage:[UIImage imageNamed:@"upparActive.png"] forState:UIControlStateNormal];
}
else
{
[self.ObjKeyLayout.btnCapKey setBackgroundImage:[UIImage imageNamed:@"Uppar_selctd_land.png"] forState:UIControlStateNormal];
}
for(UIButton *key in self.ObjKeyLayout.ArryCharKey)
{
NSString *uppercaseString = [[key currentTitle] uppercaseString];
[key setTitle:uppercaseString forState:UIControlStateNormal];
[key addTarget:self action:@selector(pressKey:) forControlEvents:UIControlEventTouchUpInside];
}
}
else
{
if(isPortrait)
{
[self.ObjKeyLayout.btnCapKey setBackgroundImage:[UIImage imageNamed:@"UpperCase.png"] forState:UIControlStateNormal];
}

[self.ObjKeyLayout.btnCapKey setBackgroundImage:[UIImage imageNamed:@"Uppar_land.png"] forState:UIControlStateNormal];
}
for(UIButton *key in self.ObjKeyLayout.ArryCharKey)
{
NSString *uppercaseString = [[key currentTitle] lowercaseString];
[key setTitle:uppercaseString forState:UIControlStateNormal];
[key addTarget:self action:@selector(pressKey:) forControlEvents:UIControlEventTouchUpInside];
}
}
