resignFirstResponder预期标识符

如果用户按回车键，我想隐藏键盘！这是.h文件

#import <UIKit/UIKit.h>


@interface ViewController : UIViewController <UITextFieldDelegate>;


@property (weak, nonatomic) IBOutlet UITextField *testItHere;

@end

和.m

    @implementation ViewController
@synthesize testItHere;
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField;
{
    [self.testItHere.resignFirstResponder]
    return YES
}

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [self updateTestKeyboard:self.interfaceOrientation];
}

- (void)viewDidLoad {
    [super viewDidLoad];

self.testItHere.delegate=self;
}

但是错误提示：期望的标识符，此代码有什么问题？
