關閉或結束UIScrollView

我有一個我寫的代碼，當按下按鈕時調用UIScrollView。問題是即使按下了另一個按鈕，它仍然保留在屏幕上。我無法弄清楚如何結束或解僱這個。關閉或結束UIScrollView

（IBAction爲）onClickSize：（ID）發送方{

viewSizePrint.hidden = YES; 
scrlView.contentSize = CGSizeMake(1500, 214); 

for (int i=0; i<20; i++) { 
    UIImageView *imgView = [[UIImageView alloc] initWithFrame:CGRectMake(158*i+22, 2, 154, 210)]; 
    imgView.tag = i+10; 
    [scrlView addSubview:imgView]; 

    UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [btn setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"layout%d_thumbnail", i+1]] forState:UIControlStateNormal]; 
    btn.frame = CGRectMake(158*i+30, 10, 138, 194); 
    btn.tag = i; 
    [btn addTarget:self action:@selector(onClickTheme:) forControlEvents:UIControlEventTouchUpInside]; 
    [scrlView addSubview:btn]; 
} 

[self refreshTheme:[AppDelegate sharedAppDelegate].shrTheme]; 

}

由於亞倫。我之前有過這樣的代碼，它引發了一個異常。這裏是它說什麼int main（int argc，char * argv []） { @autoreleasepool { return UIApplicationMain（argc，argv，nil，NSStringFromClass（[AppDelegate class]））; } } 線程1：signal：SIGABRT – MagicAlbum 2013-03-21 02:55:00
