但如果我使用分頁滾動視圖相同的代碼,它完美的我的代碼
部分:
UIButton *iButton = [UIButton buttonWithType:UIButtonTypeInfoLight];
iButton.frame = CGRectMake(269.0f, 17.0f, 18.0f, 19.0f);
iButton.backgroundColor = [UIColor clearColor];
[iButton addTarget:self action:@selector(buttonPressed)
forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:iButton];
-(void)buttonPressed{
NSLog(@"button pressed in PSV...");
}
I D不理解它,我期望它能起作用。我只是想明白爲什麼它不起作用。
靜態視圖是ViewController
頁面滾動視圖子類是UIScrollView <UIScrollViewDelegate>
感謝所有的答案的子類。
我沒有給你?你正在使用buttonPressed1或buttonPressed的選擇器是什麼?分頁滾動視圖中的 – makboney 2011-03-30 07:38:14
我在靜態視圖中使用buttonPressed我使用buttonPressed1,並且按鈕變量的名稱是iButton1 – Csabi 2011-03-30 07:49:01
您是否嘗試通過更改變量名稱以及選擇器名稱? – makboney 2011-03-30 07:56:09
