我试图找出在以下代码中按下 UIButton 的 UIButton 标题是什么。
在 viewDidLoad 上,按钮标题使用以下命令输出到控制台:
NSLog(@"The button title is %@ ", btn.titleLabel.text);
我想在按下按钮时获得这个标题。
谢谢你的帮助

// Create buttons for the sliding category menu.
NSMutableArray* buttonArray = [NSMutableArray array];
NSArray * myImages = [NSArray arrayWithObjects:@"category-cafe-unsel.png", @"category-food-unsel.png", @"category-clothing-unsel.png", @"category-health-unsel.png", @"category-tech-unsel_phone.png" , @"category-tech2-unsel.png", @"catefory-theatre-unsel.png", @"category-travel-unsel.png", nil];
// only create the amount of buttons based on the image array count
for(int i = 0;i < [myImages count]; i++)
{
// Custom UIButton
btn = [UIButton buttonWithType:UIButtonTypeCustom];
[btn setFrame:CGRectMake(0.0f, 20.0f, 52.0f, 52.0f)];
[btn setTitle:[NSString stringWithFormat:@"Button %d", i] forState:UIControlStateNormal];
[btn setImage:[UIImage imageNamed:[myImages objectAtIndex:i]] forState:UIControlStateNormal];
NSLog(@"The button title is %@ ", btn.titleLabel.text);
[btn addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[buttonArray addObject:btn];
NSLog(@"Button tag is: %d",btn.tag);
}
