我在for循环中手动添加了按钮,之后如何隐藏或更改按钮和隐藏标签?
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button.frame = CGRectMake(80.0, 170, 150.0, 30.0);
[button setTitle:@"My Button" forState:UIControlStateNormal];
[button addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:button];
UILabel *lblFileName = [[UILabel alloc] init];
lblFileName.text = [[objectArray objectAtIndex:i] valueForKey:@"fileName"];
lblFileName.textAlignment = NSTextAlignmentCenter;
[self.view addSubview:lblFileName];
-(IBAction)myAction:(id)sender
{
// hide the button or change title button and hide label
}
