UIButton 电话活动没有奏效
原标题:UIButton Touch event is not working
menuView= [[UIImageView alloc] initWithFrame:CGRectMake(0,411, 320,49)];

UIButton *test = [UIButton buttonWithType:UIButtonTypeCustom ];
test.frame = CGRectMake(0, 0, 80, 49);

[test addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];

[menuView addSubview:test];

[self.view addSubview:menuView];

我在(测试)纽特州内部联系。 但没有工作。 为什么?

最佳回答

或许请参看<代码>buttonPressed: with buttonPressed

如果你采用类似方法,

- (void)buttonPressed
{
}

你们需要使用

[test addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];

http://www.ohchr.org。

但是,根据你所做的工作,你需要采用一种类似方法。

- (void)buttonPressed:(id)sender
{
}
