Question

I have some sources below.

- (void)Button:(UIButton *)button {

    NSString *imageName = ((UIButton *)[self.view viewWithTag:button.tag]).titleLabel.text; 

}

- (void)viewDidLoad { 

    NSMutableArray *_array = [[NSMutableArray alloc] init];

    NSInteger iCount = [_array count];

    for (i = 0; iCount > i; i++) {

        UIButton *btn = [[UIButton alloc] init];
        btn.titleLabel.text = [[_array objectAtIndex:i] objectForKey:@"FILE"];
        btn.tag = i;
        [btn addTarget:self action:@selector(Button:) forControlEvents:UIControlEventTouchUpInside];
        [self.view addSubview:btn];
        [btn release];

}

When I access Button method with 0 index tag, I get SIGABRT error.
What can I do ?

Read your console output properly, by default every view has the tag ‘0’, so it can be crashed because it is taking some other view besides of uibutton, and may be that view don’t not have the titleLabel property.Because it is the property of UIButton.
