1、Return按扭收起键盘
- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
return [textField resignFirstResponder];
}
2、调用resignFirstResponder
[self.textF resignFirstResponder]
3、任何地方加上这句代码，统一收起键盘
[[[UIApplication sharedApplication] keyWindow] endEditing:YES];
或者这句统一回收键盘
[[UIApplication sharedApplication] sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];
