1)首先得遵守協議UITextFieldDelegate @interface userInfoViewController()<UITextFieldDelegate> 2)設置代理(下麵的self都是輸入框所在的父view) textField.delegate = self; 3)實現UITextFieldDelegate的三個方法即可： - (BOOL)textFieldShouldReturn:(UITextField *)textField {
[textField resignFirstResponder];
return YES;
} /***下麵是全屏的一個view, view上有子控制項 textField的使用方法***/ - (void)textFieldDidBeginEditing:(UITextField *)textField { CGRect frame = textField.frame; int offset = frame.origin.y + 32 - (self.frame.size.height - 256.0);//鍵盤高度256, textField高度32
NSTimeInterval animationDuration = 0.30f;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
//將視圖的Y坐標向上移動offset個單位，以使下麵騰出地方用於軟鍵盤的顯示
if(offset > 0)
self.frame = CGRectMake(0.0f, -offset, self.frame.size.width, self.frame.size.height);
[UIView commitAnimations]; } - (void)textFieldDidEndEditing:(UITextField *)textField { self.frame =CGRectMake(0, 0, self.frame.size.width, self.frame.size.height); } /***下麵是全屏的一個view, view上有tableView, 每個tableViewCell有子控制項 textField的使用方法***/ - (void)textFieldDidBeginEditing:(UITextField *)textField
{
CGRect frame = textField.frame;
int index = (int)(textField.tag - 0x1000);
//30為textField的高度, (index - 1)為前面有幾個cell, 90為tableView的y,即輸入框底部距self.view的高度減去鍵盤的頂部距self.view的高度
int offset = frame.origin.y + (index - 1) * 50 + 30 + 90 - (self.view.frame.size.height - 256.0);//鍵盤高度256
NSTimeInterval animationDuration = 0.30f;
[UIView beginAnimations:@"ResizeForKeyboard" context:nil];
[UIView setAnimationDuration:animationDuration];
//將視圖的Y坐標向上移動offset個單位，以使下麵騰出地方用於軟鍵盤的顯示
if(offset > 0)
self.infoList.frame = CGRectMake(10.0f, 90 - offset, self.infoList.frame.size.width, self.infoList.frame.size.height);
[UIView commitAnimations];
}
- (void)textFieldDidEndEditing:(UITextField *)textField
{
self.infoList.frame =CGRectMake(10, 90, [UIScreen mainScreen].bounds.size.width - 20, 300); } 效果截圖:
