-(IBAction) buttonClick:(id)sender
{
UIButton *button = (UIButton *) sender;
NSString *title = [NSString stringWithFormat:
@"Button tag %d",button.tag];
NSString *message = [button currentTitle];
UIAlertView *alert = [[UIAlertView alloc] initWithFormat:title
message:message
delegate:self
cancelButtonTitle:@"OK"
otherButtonTitle:nil];
[alert show];

[alert release];

这个哪里错了，有红色感叹号
