如何为 UIButton 获取标题，它被按下时

Answer 1

// 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);

}

解决方法 :
在您的操作：
- (void) buttonPressed:(UIButton*) sender {
NSLog(@"The button title is %@",sender.titleLabel.text);
}
