我試圖發現UIButton標題是哪個UIButton在下面的代碼中被按下。如何獲得它被按下時UIButton的標題
在viewDidLoad中的按鈕標題輸出到使用控制檯:
NSLog(@"The button title is %@ ", btn.titleLabel.text);
我想當按下按鈕,而不是得到這個稱號。
感謝您的幫助

// 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);
}
這和'sender.currentTitle'有什麼區別? –
無。你說得對,我會編輯答案。 – Zaphod
我沒有說這不是,我只是問。剛纔'currentTitle'是'nil',但'titleLabel.text'不是。 –
