ボタンに単純な問題があります。タイトルが表示されません。私のコードは次のとおりです。
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setImage:[UIImage imageNamed:[NSString stringWithFormat:@"ikonki%d.png",i]] forState:UIControlStateNormal];
[button setTitle:@"Normal" forState:UIControlStateNormal];
[button setTitleColor: [UIColor whiteColor] forState: UIControlStateNormal];
[button setEnabled:YES];
[button addTarget:self
action:@selector(buttonHandler:)
forControlEvents:UIControlEventTouchUpInside];
button.tag = i;
button.frame = CGRectMake(10. + 77. * i, 125., 68 , 68);
[self.view addSubview:button];
