for (int i = 0; i < ABMultiValueGetCount(emails) ; i++)
{
CFStringRef email = ABMultiValueCopyValueAtIndex(emails, i);
//CFStringRef emailType = ABMultiValueCopyLabelAtIndex(emails, i);
emailString = (NSString *)email;
//emailTypeString = (NSString *)emailType;
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(15, 320 - x, 290, 40);
[button setTitle:emailString forState:UIControlStateNormal];
button.titleLabel.font = [UIFont fontWithName:@"Helvetica Bold" size:18];
[button addTarget:self action:@selector(OnEmailIdSelection:) forControlEvents:UIControlEventTouchUpInside];
[self.selectEmailId addSubview:button];
x = x+70;
}
}

试试这个:
-(void) OnEmailIdSelection:(id)sender
{
if ([sender isKindOfClass:[UIButton class]])
{
UIButton *button = (UIButton*)sender;
NSString *title = button.currentTitle;
// do whatever you want with title
}
}

-(void) OnEmailIdSelection:(id)sender {
UIButton* button = (UIButton*)sender;
NSString* title = [button titleForState: UIControlStateNormal];
}
