多文本字段的自定义键盘

Question

How can I use a custom keypad I have made with multiple text fields.

So far I can do it for one but not for the others.

Following is my code for the 'C' button on my customer keypad but only works for textFieldLoanAmount

-(IBAction) clearAll:(id)sender{

currentValue = 0.0;
[stringValue setString:@""];
textFieldLoanAmount.text = @"0";
dotPressed = NO;

Any guidance will be appreciated.

也许您应该具有某种指向当前活动文本字段的属性？
