有些时候,我的应用程序因显示 * 而崩溃,而且在枚举时突变了。这一直发生在同一行代码中。请帮我解决这个问题。我坚持这个。应用程序在推送我的代码的视图控制器行时崩溃。但它不常见。我的错误控制台
由于未捕获的异常'NSGenericException'而终止应用程序,原因:' * 集合CALayerArray:0x1030c730在枚举时发生了变异。 “” “” “” “” “” “” “” “” “” “” “” “” “” “” “” “” “” “” )'
我的代码:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
ServiceDetails *service=[[ServiceDetails alloc] initWithNibName:@"ServiceDetails" bundle:nil];
CompanyListingForm *list=[[CompanyListingForm alloc]initWithNibName:@"CompanyListingForm" bundle:nil];
[category_company_text resignFirstResponder];
if(viewHoldingTable)
{
[viewHoldingTable removeFromSuperview];
}
if (category_clicked_flag==0) {
if (location_or_cat_com==0) {
NSMutableArray *get=[district_array objectAtIndex:indexPath.row];
locationid=[[get objectAtIndex:0]intValue];
[location_textfield resignFirstResponder];
location_textfield.text=[get objectAtIndex:1];
}
else
{
if (draggingView) {
[draggingView removeFromSuperview];
}
if (viewHoldingTable) {
[viewHoldingTable removeFromSuperview];
}
NSMutableArray *get=[company_array objectAtIndex:indexPath.row];
category_company_text.text=[get objectAtIndex:1];
service.ida=[NSString stringWithFormat:@"%d",[[get objectAtIndex:0] intValue]];
service.idloc=[NSString stringWithFormat:@"%d",locationid];
[self.navigationController pushViewController:service animated:YES];//getting error at this point.
//[emer release];
}
}
else
{
if (location_or_cat_com==0) {
NSMutableArray *get=[district_array objectAtIndex:indexPath.row];

}

}

我认为问题在于,当您要求推送视图控制器时,您正在对界面执行所有这些操作。尝试将pushViewController
行包裹在dispatch_after
块中,延迟时间为.1秒,以便对接口时间进行其他更改以便安定下来。或者以另一种方式执行:将removeFromSuperview
内容放入延迟中。更好的是,抛出某种标志,以便稍后在viewWillAppear
上删除要从superview中删除的内容。你现在不需要这样做;无论如何,你都要用推动的视图控制器来隐藏这个视图。
