iOS-OC-自定义键盘

自定义键盘，用于输入一些比较机密的字符串；

上代码

- (void)createTextField3{
UITextField *textFiled = [[UITextField alloc] initWithFrame:CGRectMake(10, 50, 300, 40)];
textFiled.borderStyle = UITextBorderStyleRoundedRect;//背景色白色
textFiled.tag = 100;
view = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 1, 216)];
NSArray *array = @[@"1",@"2",@"3",@"4",@"5",@"6",@"7",@"8",@"9",@"0"];
CGFloat xSpace = (ScreenWidth-40*4)/5.0;
CGFloat ySpace = (216-40*3)/4.0;
for(int i=0;i<3;i++){
for(int j=0;j<4;j++){
UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
button.frame = CGRectMake(xSpace+j*(xSpace+40), ySpace+i*(ySpace+40), 40, 40) ;
[button setTitle:[array objectAtIndex:i*4+j] forState:UIControlStateNormal];
[button addTarget:self action:@selector(buttonClick:) forControlEvents:UIControlEventTouchUpInside];
button.titleLabel.font = [UIFont systemFontOfSize:30];
[view addSubview:button];
}
}
view.backgroundColor = [UIColor colorWithRed:0.961 green:0.961 blue:0.961 alpha:1.00];
textFiled.inputView = view;

UIView *accessoryView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 1, 25)];
accessoryView.backgroundColor = [UIColor orangeColor];
UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
[button setTitle:@"收键盘1" forState:UIControlStateNormal];
button.frame = CGRectMake(0, 0, 70, 25);
[button addTarget:self action:@selector(buttonClickTwo:) forControlEvents:UIControlEventTouchUpInside];
[accessoryView addSubview:button];
textFiled.inputAccessoryView = accessoryView;
[accessoryView release];
[self.view addSubview:textFiled];
[textFiled release];
}

- (void)buttonClickTwo:(UIButton *)button{
for (UIView *view1 in self.view.subviews){
if([view1 isMemberOfClass:[UITextField class]]){
UITextField *tf = (UITextField *)view1;
[tf resignFirstResponder];
}
}
}

- (void)buttonClick:(UIButton *)button{
UITextField * textField = (UITextField *)[self.view viewWithTag:100];
textField.text = [textField.text stringByAppendingString:button.titleLabel.text];
}
