iOS开发之自定义键盘(一)

这里我以两个textfield为例

//** 这里没有把键盘写成一个单独的View, 只提供一个思路
/

{    UITextField *textPhone;    UITextField *textCarNo;}

// 自定义一个View@property (nonatomic, strong) UIView *bottomView;

// textField@property (nonatomic, strong) UITextField *textField;

// 把view赋值给系统键盘 -- 在self.bottomView可以为所欲为了...self.textField.inputView = self.bottomView;

// inputButton上的点击方法---输入- (void)inputChars:(UIButton *)sender{    NSString *text = [NSString stringWithFormat:@"%@", sender.titleLabel.text];    [self changetext:text];}

- (void)changetext:(NSString *)text{// 逻辑处理    if ([textPhone isFirstResponder]) {        NSString *iphoneText = textPhone.text;        if (iphoneText.length > 10) {            return;        }        textPhone.text = [NSString stringWithFormat:@"%@%@", iphoneText, text];    }    if ([textCarNo isFirstResponder]) {        NSString *carNumber = textCarNo.text;        if (carNumber.length > 6) {            return;        }        textCarNo.text = [NSString stringWithFormat:@"%@%@", carNumber, text];    }}

// deleteButton上的点击方法---删除- (void)deleteChars:(UIButton *)sender{    if ([textPhone isFirstResponder]) {        NSString *deleteBefore = textPhone.text;        if (deleteBefore.length > 0) {            NSString *deleteAfter = [deleteBefore substringToIndex:deleteBefore.length - 1];            textPhone.text = deleteAfter;        }    }    if ([textCarNo isFirstResponder]) {        NSString *deleteBefore = textCarNo.text;        if (deleteBefore.length > 0){            NSString *deleteAfter = [deleteBefore substringToIndex:deleteBefore.length - 1];            textCarNo.text = deleteAfter;        }    }}

这样简单的自定义键盘就完成了...
