Iphone 导航视图没有';第一次点击就不能工作
我有一个导航视图,当我单击时,我只显示行号 在主视图中:Iphone 导航视图没有';第一次点击就不能工作,iphone,objective-c,xcode4,Iphone,Objective C,Xcode4,我有一个导航视图,当我单击时,我只显示行号 在主视图中: -(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ if (read == nil) { readNotice *aController = [[readNotice alloc]initWithNibName:@"readNotice" bundle:nil]; self.read =
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if (read == nil) {
readNotice *aController = [[readNotice alloc]initWithNibName:@"readNotice" bundle:nil];
self.read = aController;
}
[read updateRowNumber:indexPath.row];
[[self navigationController] pushViewController:read animated:YES];
在我的readNotice
课程中:
-(void)updateRowNumber:(int)theindex {
rowNumber = theindex + 1;
message.text = [NSString stringWithFormat:@"row %i was clicked", rowNumber];
NSLog(@"view did load row = %d", rowNumber);
}
readNotice.xib仅包含一个标签
我第一次点击它时会显示“标签”,但在下面的尝试中它会起作用
我想我需要对我错过的东西进行初始化,但我找不到它
提前感谢使用-
if (self.read == nil) {
readNotice *aController = [[readNotice alloc]initWithNibName:@"readNotice" bundle:nil];
self.read = aController;
}
--------
---------
[[self navigationController] pushViewController:self.read animated:YES];
我不明白你为什么把read变量?用这个
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
readNotice *aController = [[readNotice alloc]initWithNibName:@"readNotice" bundle:nil];
[self.navigationController pushViewController:aController animated:YES];
[aController updateRowNumber:indexPath.row];
}
希望这能帮助你 试试这个,
在tableview:DidSelectRowatinex方法中
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if (read == nil) {
readNotice *aController = [[readNotice alloc]initWithNibName:@"readNotice" bundle:nil];
self.read = aController;
}
read.index = indexPath.row;
[[self navigationController] pushViewController:read animated:YES];
在readNotice
中创建一个实例变量,如下所示
@property(assign) int index;
@synthesize index;
在readNotice
viewDidLoad方法中,只需调用updateRownNumber
- (void)viewDidLoad
{
[super viewDidLoad];
[self updateRowNumber:index];
}
它将按照您的预期显示数字我只建议使用适当的视图控制器,所需的rest代码需要到位。当您单击单元格时,新的视图控制器是否打开?
