其实说白了，就是将系统的return 键换成搜索，然后对renturn 事件作处理

通过红色的设置，就可以在系统键盘（系统键盘或者搜狗输入法）上显示“搜索”字段了。

 UIImageView *_seachView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"search"]];_seachView.frame = CGRectMake(15, 50, 10, 10);_searchTextField = [self generateTextField];_searchTextField.placeholder = @"  请输入司机的卡号或手机号";[_searchTextField setFrame:CGRectMake(15, 0, kDEVICEWIDTH - 100, 30)];_searchTextField.leftView = _seachView;_searchTextField.layer.borderColor = ([[CHUtil colorWithHexString:@"c7c7c9"]CGColor]);[_searchTextField setValue:[CHUtil colorWithHexString:@"c5c5c5"] forKeyPath:@"_placeholderLabel.textColor"];[_searchTextField addTarget:self action:@selector(searchTextFieldChangeAction:)forControlEvents:UIControlEventEditingChanged];<span style="color:#ff0000;"> _searchTextField.returnKeyType = UIReturnKeySearch; //设置按键类型_searchTextField.enablesReturnKeyAutomatically = YES; //这里设置为无文字就灰色不可点</span>[_contentView addSubview:_searchTextField];

获取搜索的点击事件：红色就是处理搜索点击的事件。

#pragma mark -- UITextFieldDelegate method
-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{[self resignTextResponder];
}<span style="color:#ff0000;">- (BOOL)textFieldShouldReturn:(UITextField *)textField
{[self resignTextResponder];if(textField.returnKeyType==UIReturnKeySearch){if ([_searchTextField.text length] > 0){[self dealWithSearchText:_searchTextField.text];}}return YES;
}</span>- (void)resignTextResponder
{if ([_searchTextField isFirstResponder]){[_searchTextField resignFirstResponder];}
}
