UIButton Touch事件无效

Question

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];

I touch up inside (test ) button. but is not working . why??

Answer 1

Maybe you mixed buttonPressed: with buttonPressed .

If you implement a method like

- (void)buttonPressed
{
}

You need use

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

Note : Pay attention on the colon .

But depending on what you have done, you need implement a method like

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

Answer 2

for a cleaner solution you can try HMUIButtonOnTouch

[self.myButton onTouchInside:^{
    NSLog(@"button tap");
}];
