1. UITextFieldDelegate的代理
開始輸入的監(jiān)聽:
// return NO to disallow editing.
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField;
輸入結(jié)束的監(jiān)聽:
- (void)textFieldDidEndEditing:(UITextField *)textField;
等等。在這些方法中,添加相應(yīng)的操作。
2.獲取UITextField輸入內(nèi)容
[self.accountText addTarget:self action:@selector(input:) forControlEvents:UIControlEventEditingChanged];
- (void) input:(UITextField*)textField {
}

[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardShow:)
name:UIKeyboardDidShowNotification
object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(keyboardWillHide:)

[[NSNotificationCenter defaultCenter] addObserver:self
