IOS Customkeyboard。 如何在自定义键盘中设置特殊字符

我正在为iPhone 6和6Plus的自定义键盘工作。 我已经开发了Shift键active – inactive或123和abc键的逻辑。 但我也想显示自定义的符号，如苹果键盘显示。 请检查图像。

在这里输入图像说明

目前我可以将大写更改为小写，123更改为abc，但是如何设置此特殊字符。 注： – 我在github上search了很多演示，但是我无法在任何自定义键盘中看到特殊字符。

这是我的大写和ABC-123button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]; } 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 { sender.selected=!sender.selected; 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) { [key setTitleColor:[UIColor clearColor] forState:UIControlStateNormal]; if(isPortrait) { [key setBackgroundImage:[UIImage imageNamed:[arrKeyImages objectAtIndex:i]] forState:UIControlStateNormal]; } else { [key setBackgroundImage:[UIImage imageNamed:[keyIpad objectAtIndex:i]] forState:UIControlStateNormal]; } ; NSString *uppercaseString = [arrAlphabet objectAtIndex:i]; [key setTitle:uppercaseString forState:UIControlStateNormal]; [key addTarget:self action:@selector(pressKey:) forControlEvents:UIControlEventTouchUpInside]; i++; // is123selected=NO; } } }

你把它的两个数组，一个用于alphabetical和其他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在123或ABC keyBoard上。

以编程方式添加事件如下。 

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

将123更改为ABC或ABC更改为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++; } } }

输出：

我用这种方式设置了我的问题，因为我也设置了键的图像。
