本文介绍了如何在iOS应用中实现文本框在编辑和结束编辑时的动画效果，包括平移动画和键盘消失的处理。

我发这篇的初衷很简单, 就是我用到得时候直接copy的, 完全没有技术难点什么的

#pragma mark ----编辑不被遮挡
// textField上移动画
- (void)textFieldAnimate:(UITextField*)textField isUp:(BOOL)isUp{
    int movementDistance =140;
    // 根据需要调整平移距离
    float movementDuration = 0.3f;
    int movement = (isUp ? -movementDistance : movementDistance);
    [UIViewbeginAnimations:@"textFieldAnimation" context:nil];
    [UIViewsetAnimationBeginsFromCurrentState:YES];
    [UIViewsetAnimationDuration:movementDuration];
    self.view.frame= CGRectOffset(self.view.frame,0, movement);
    [UIViewcommitAnimations];
}
#pragma mark- TextField Delegate
- (void)textFieldDidBeginEditing:(UITextField*)textField{
    [selftextFieldAnimate:textFieldisUp:YES];
}

- (void)textFieldDidEndEditing:(UITextField*)textField{
        [selftextFieldAnimate:textFieldisUp:NO];
}

#pragma mark ----键盘消失
- (void)resignKeyboard
{
    [_communityTFresignFirstResponder];
}

-(void)touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event
{
    [_communityTFresignFirstResponder];

}

#pragma mark ----修改placeholder的字体颜色、大小

textField.placeholder = @"username is in here!";
[textField setValue:[UIColor redColor] forKeyPath:@"_placeholderLabel.textColor"];
[textField setValue:[UIFont boldSystemFontOfSize:16] forKeyPath:@"_placeholderLabel.font"];
