在UIViewController中收起鍵盤，除了調(diào)用相應(yīng)控件的resignFirstResponder。例：
- 利用textField的代理方法
- (BOOL)textFieldShouldReturn:(UITextField *)textField{
if (![self.textField isExclusiveTouch]) {
[self.textField resignFirstResponder];
}
return YES;
}
還有另外的三種方法：
- 重載UIViewcontroller中的touchesBegin方法，然后在里面執(zhí)行[self.view endEditing:YES]; ，這樣單擊UIViewController的任意地方就可以收起鍵盤。
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
[self.view endEditing:YES];
}
- 直接執(zhí)行[[UIApplication sharedApplication] sendAction: @selector(resignFirstResponder to:nil from:nil forEvent:nil];，用于在獲得當前UIViewController比較困難的時候用。
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
[[UIApplication sharedApplication]sendAction:@selector(resignFirstResponder) to:nil from:nil forEvent:nil];
}
- 直接執(zhí)行 [[[UIApplication sharedApplication] keyWindow] endEditing:YES];
- (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{
[[[UIApplication sharedApplication] keyWindow] endEditing:YES];
}
