我的UIButton在模拟器中运行完美,但在iOS4的iPhone上运行
picButton = [[UIButton alloc] initWithFrame:CGRectMake(165, 80, 90, 150)];
[picButton addTarget:self action:@selector(mailIt:) forControlEvents:UIControlEventTouchUpInside];
[picButton setBackgroundImage:[UIImage imageNamed:@"save_2.png"] forState:UIControlStateNormal];
[picButton setBackgroundImage:[UIImage imageNamed:@"save_2.png"] forState:UIControlStateSelected];
在iPhone上按钮显示正确,看起来已按下,但动作未启动。
稍后编辑: 这是mailIt:
的代码-(IBAction) mailIt : (id)delegate{
MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];
picker.mailComposeDelegate = self;
[picker setSubject:@"title!"];
NSString *emailBody = [NSString stringWithFormat:@"messagestring", imagename];
[picker setMessageBody:emailBody isHTML:YES];
[self presentModalViewController:picker animated:YES];
[picker release];
}

我认为您应该检查您的设备是否配置为发送邮件,因为您使用的是MFMailComposeViewController,但是您没有检查代码是否能够使用canSendMail方法显示视图。
要将设备配置为发送邮件,您需要启动邮件应用并设置电子邮件。

picker.mailComposeDelegate = self;
应该是
picker.mailComposeDelegate = camera;
