<UIPickerViewDataSource,UIPickerViewDelegate>

實現方法

//創建 UITextField 設置setInputAccessoryView 為自己定義Toolbar 而且將鍵盤樣式更改為鍵盤選擇器
-(void)creatTextField{
    UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(10, 64, [UIScreen mainScreen].bounds.size
 
.width - 20, 44)];
    [textField setInputAccessoryView:self.kbToolbar];

    //自己定義鍵盤選擇器
    UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 50, kScreenWidth, 320)];
    [pickerView setDataSource:self];
    [pickerView setDelegate:self];
    //選擇指示器
    [pickerView setShowsSelectionIndicator:YES
 
];
    //鍵盤類型自己定義
    [self.sourceFD setInputView:pickerView];

    [textField setInputView:pickerView];
    [self.view addSubview:textField];
}

實現數據源和代理方法

#pragma mark - UIPickerViewDelegate 和 UIPickerViewDataSource
//必須實現
// returns the number of ‘columns‘ to display. ->選擇器一共同擁有多少列!
- (NSInteger
 
)numberOfComponentsInPickerView:(UIPickerView *)pickerView{
    return 1;
}

// returns the # of rows in each component.. -> 選擇器每列有多少行!
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component{
    return 5;
}

//選擇器每行名稱
-(NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component{
    if (row == 0) {
        return @"人民幣(RMB)";
    }else if (row == 1){
        return @"美元(USD)";
    }else if (row == 2){
        return @"英鎊(GBP)";
    }else if (row == 3){
        return @"日元(JPY)";
    }else if (row == 4){
        return @"歐元(EUR)";
    }else{
        return @"..";
    }
}
