這是我的代碼。
- (void)viewDidLoad {
[super viewDidLoad];
helpButton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
helpButton.frame= CGRectMake(5, 370, 90, 30);
[helpButton setTitle:[NSString stringWithFormat:@"Help"] forState:UIControlStateNormal];
[helpButton addTarget:self action:@selector(btnClicked:) forControlEvents:UIControlEventTouchUpInside];
helpButton.tag=1;
[self.view addSubview:helpButton];
}
