Question

我创建视图并释放所有对象。我使用了NSTimer和

//at viewdidload
NSTimer *timer = [NSTimer scheduledTimerWithTimeInterval: 15.0
                                                      target: self
                                                    selector:@selector(selectorSwitcher:)
                                                    userInfo: nil repeats:YES];
    NSRunLoop *runner = [NSRunLoop currentRunLoop];
    [runner addTimer:timer forMode: NSDefaultRunLoopMode];

-(void)selectorSwitcher:(NSTimer *)timer {
        [self viewDidLoad];
}

但myviews无法从scrollview中删除。创建更多其他人的观看次数。我该如何解决这个问题？感谢

  if (tempView.frame.origin.x > createview.frame.size.width) {


            tempLabel = [[UILabel alloc] initWithFrame:CGRectMake((lblname_marginleft + (i * widthOfView))-((i/sutun)*mview_width), lblname_margintop + ((i/sutun) * heightOfView), labelwidth, labelheight)];

            tempNumber = [[UILabel alloc] initWithFrame:CGRectMake((lblnumber_marginleft + (i* widthOfView))-((i/sutun)*mview_width), lblnumber_margintop + ((i/sutun) * heightOfView), labelwidth, labelheight)];

            tempyuzde= [[UILabel alloc] initWithFrame:CGRectMake((15 + (i*widthOfView))-((i/sutun)*mview_width), 10 + ((i/sutun) * heightOfView), labelwidth, labelheight)];

            tempView = [[UIView alloc] initWithFrame:CGRectMake((10 + (i* widthOfView)) - ((i/sutun)*mview_width), ((i/sutun) * heightOfView), widthOfView, heightOfView)];

您不应该调用viewDidLoad - 系统会在视图加载后调用它。要加载视图，只需执行以下操作：

UIView *view = self.view;

调用self.view隐式加载XIB文件。但是，系统还会在需要时自动加载视图 - 您要实现哪些功能？

此外，你不应该打电话

NSRunLoop *runner = [NSRunLoop currentRunLoop];
[runner addTimer:timer forMode: NSDefaultRunLoopMode];

由于通过调用scheduledTimerWithTimeInterval...您已经安排了计时器 - 您无需再次安排计时器。

NSTimer和UIView内存错误
