关闭键盘
在UIView或UIViewController中触摸文本框的其它区域，将关闭键盘结束编辑
// 在UIView 或 UIViewController中重写touchesBegan
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
[self endEditing:YES];
}
键盘动画
// 在block中更改 frame 将跟键盘的动画同步
// kbSize 弹出键盘的具体尺寸
+ (void)animateWithKeyBoardForNotification:(NSNotification *)note block:(void (^)(CGSize kbSize))block
{
NSDictionary* userInfo = [note userInfo];
NSTimeInterval animationDuration;
UIViewAnimationCurve animationCurve;
[[userInfo objectForKey:UIKeyboardAnimationCurveUserInfoKey] getValue:&animationCurve];
[[userInfo objectForKey:UIKeyboardAnimationDurationUserInfoKey] getValue:&animationDuration];
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:animationDuration];
[UIView setAnimationCurve:animationCurve];
NSDictionary* info = [note userInfo];
CGSize kbSize = [[info objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;
block(kbSize);
[UIView commitAnimations];
}
//调用的例子
- (void)keyboardDidShow:(NSNotification *)note
{
[Global animateWithKeyBoardForNotification:note block:^(CGSize kbSize) {
self.view.center = CGPointMake(originalCenter.x, originalCenter.y-kbSize.y);
}];
}
