如何获得一个UIButton按下时的标题
我试图发现在下面的代码中按下哪个UIButton的UIButton标题是什么。
on viewDidLoadbutton标题输出到控制台使用:
NSLog(@"The button title is %@ ", btn.titleLabel.text);
当按下button时,我想获得这个标题。
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); }
在你的行动中:
- (void) buttonPressed:(UIButton*) sender { NSLog(@"The button title is %@",sender.titleLabel.text); }
编辑 :或作为评论Iulian: sender.currentTitle
,但它可能是nil
,请参阅迈克尔的意见。
你应该有某个地方的function…
- (void)buttonPressed:(id)sender
把它放在里面
- (void)buttonPressed:(id)sender { UIButton *someButton = (UIButton*)sender; NSLog(@"The button title is %@ ", [someButton titleForState:UIControlStateNormal]); //You should also be able to use... //NSLog(@"The button title is %@ ", someButton.titleLabel.text); }
NSString * strButtonTitle = [btnButton titleForState:state];
哪里状态:
UIControlStateNormal, UIControlStateHighlighted, UIControlStateDisabled, UIControlStateSelected, UIControlStateFocused, UIControlStateApplication, UIControlStateReserved
为了您的要求
NSString * strButtonTitle = [btnButton titleForState:UIControlStateSelected];
这是在任何给定的时间在程序中获取button的不同状态的标题的方法…但基于来自Zaphod的问题答案是好的。
