You can check to see if the text field is editing:
您可以检查文本字段是否正在编辑：
if (textFieldSomething.isEditing) {
...
}
See the UITextField class referencefor details.
有关详细信息，请参阅UITextField 类参考。
回答by MBU
you can implement the textFieldDidBeginEditing function to catch the action event when the text field is being edited.
您可以实现 textFieldDidBeginEditing 函数来捕获正在编辑文本字段时的动作事件。
-(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible
//perform actions.
}
