我正在为 iphone 6 和 6Plus 定制键盘。我已经开发了 Shift 键活动-非活动或 123 和 abc 键的逻辑。但我还想显示自定义符号，如所示的苹果键盘。请查看图片。
目前我可以将大写更改为小写，将 123 更改为 abc，但是我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。
这是我的逻辑大写 and ABC-123 Button.
-(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];
}
else
{
[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];
}
}
}
- (IBAction)action123:(UIButton*)sender // To set 123 and ABC

if(sender.selected)
{
[self.ObjKeyLayout.btn123Key setTitle:@"ABC" forState:UIControlStateNormal];
int i=0;
for(UIButton *key in self.ObjKeyLayout.ArryCharKey)
{
[key setTitleColor:[UIColor clearColor] forState:UIControlStateNormal];
NSLog(@"\n\n123isSelected\nI-%i\tArrayCharKey.Count:-%i",i,(int)self.ObjKeyLayout.ArryCharKey.count);
if(isPortrait)
{
NSLog(@"\n\n123isSelected\nI-%i\tArrayCharKey.Count:-%i\nArraySpecialImageKey.Count-%i\n",i,(int)self.ObjKeyLayout.ArryCharKey.count,(int)arrspecialImageKey.count);
[key setBackgroundImage:[UIImage imageNamed:[arrspecialImageKey objectAtIndex:i]] forState:UIControlStateNormal];
}
else{
[key setBackgroundImage:[UIImage imageNamed:[arrSpecialIpad objectAtIndex:i]] forState:UIControlStateNormal];
}
[key setTitle:[NumKey objectAtIndex:i] forState:UIControlStateNormal];
[key addTarget:self action:@selector(pressKey:) forControlEvents:UIControlEventTouchUpInside];
i++;
}
}
else
{
[self.ObjKeyLayout.btn123Key setTitle:@"123" forState:UIControlStateNormal];
int i=0;
for(UIButton *key in self.ObjKeyLayout.ArryCharKey)

}
;
NSString *uppercaseString = [arrAlphabet objectAtIndex:i];
[key setTitle:uppercaseString forState:UIControlStateNormal];
[key addTarget:self action:@selector(pressKey:) forControlEvents:UIControlEventTouchUpInside];
i++;
// is123selected=NO;
}
}

你拿两个数组，一个用于alphabetical和其他用于numerical
NSArray *NumKey;
NSArray *arrAlphabet;
Now in NumKey :
NumKey=[[NSArray alloc]initWithObjects:@"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"0", @"-", @"/", @":", @";", @"(", @")", @"$", @"&", @"@", @"\"", @".", @",", @"?", @"!",@"'",@"^", nil];
and 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];
键盘中的 IBOutlet123 or ABC.
以编程方式添加事件，如下所示。
[self.keybard.btnNumeric addTarget:self action:@selector(action123:) forControlEvents:UIControlEventTouchUpInside];
改变方法123 to ABC or ABC to 123
- (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++;
}
}
}
output:
