iphone中键盘的展示和隐藏

iphone中键盘的显示和隐藏

ios不比android，没返回键，需要自己隐藏键盘，下面是我常用的方法，分享给大家

textfile开始编辑事件为“Editing did Begin” ，结束事件为“Did end on exit”

方法一

- (IBAction)exitKeyboard:(id)sender {    [sender resignFirstResponder];    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];    [UIView setAnimationDuration:0.30f];    CGRect frame = self.view.frame;          frame.origin.y +=216;            frame.size. height -=216;         self.view.frame = frame;      [UIView commitAnimations];}- (IBAction)editBegin:(id)sender {    [UIView beginAnimations:@"ResizeForKeyboard" context:nil];    [UIView setAnimationDuration:0.30f];       CGRect frame = self.view.frame;      frame.origin.y -=216;      frame.size.height +=216;      self.view.frame = frame;         [UIView commitAnimations];} 

方法二

-(IBAction) slideFrameUp{    [self slideFrame:YES];}-(IBAction) slideFrameDown{    [self slideFrame:NO];}-(void) slideFrame:(BOOL) up{    const int movementDistance = 60; // tweak as needed    const float movementDuration = 0.3f; // tweak as needed        int movement = (up ? -movementDistance : movementDistance);        [UIView beginAnimations: @"anim" context: nil];    [UIView setAnimationBeginsFromCurrentState: YES];    [UIView setAnimationDuration: movementDuration];    self.view.frame = CGRectOffset(self.view.frame, 0, movement);    [UIView commitAnimations];}

注，此方法，如果用navigationViewController push到下一View的时候，需要 添加下面代码，将textfiled的状态取消，否则pop回来时候，view的未知会有问题，或者键盘不隐藏

[tfPwd resignFirstResponder]; [tfAccount resignFirstResponder];
