我正在研究一个有uitableview的地方,我想在每个单元格中添加一个uitextfield,以便它可以用作表单。可以有大约15个这样的uitextfields。但由于屏幕上的空间很小,一次只显示5行,而其他行则在滚动时显示。
当我尝试从所有这些uitextfields获取数据时,我只能为那些可见的人和其他人获得它。它应该因为我没有使用重用标识符。
以下是我的CellfoRrowAtIndex代码:
editContactCell *tcell = (editContactCell*) [tableView dequeueReusableCellWithIdentifier:nil];
NSArray *nib= [[NSBundle mainBundle] loadNibNamed:@"editContactCell" owner:self options:nil];
tcell = (editContactCell *)[nib objectAtIndex:0];
tcell.accessoryType = UITableViewCellAccessoryNone;
tcell.selectionStyle = UITableViewCellSelectionStyleNone;
tcell.txtDetails.tag = indexPath.row+50;
if([dictClientDetails count]>0){
if(indexPath.section==0 && indexPath.row==0){
tcell.lblTitle.text = @"Mobile:";
tcell.txtDetails.placeholder = @"Mobile:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"Mobile"];
}
}
else if(indexPath.section==0 && indexPath.row==1){
tcell.lblTitle.text = @"Work:";
tcell.txtDetails.placeholder = @"Work:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"Work_number"];
}
}
else if(indexPath.section==1 && indexPath.row==0){
tcell.lblTitle.text = @"Email:";
tcell.txtDetails.placeholder = @"Email:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"Email"];
}
}
else if(indexPath.section==2 && indexPath.row==0){
tcell.lblTitle.text = @"IM1:";
tcell.txtDetails.placeholder = @"IM1:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"IM1"];
}
}
else if(indexPath.section==2 && indexPath.row==1){
tcell.lblTitle.text = @"IM2:";
tcell.txtDetails.placeholder = @"IM2:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"IM2"];
}
}
else if(indexPath.section==3 && indexPath.row==0){
tcell.lblTitle.text = @"Based In:";
tcell.txtDetails.placeholder = @"Based In:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"Location"];
}
}
else if(indexPath.section==3 && indexPath.row==1){
tcell.lblTitle.text = @"Address:";
tcell.txtDetails.placeholder = @"Address:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"Address"];
}
}
else if(indexPath.section==4 && indexPath.row==0){
tcell.lblTitle.text = @"Division:";
tcell.txtDetails.placeholder = @"Division:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"Division"];
}
}
else if(indexPath.section==4 && indexPath.row==1){
tcell.lblTitle.text = @"Department:";
tcell.txtDetails.placeholder = @"Department:";
if([dictClientDetails count]>0){
tcell.txtDetails.text = [dictClientDetails objectForKey:@"Department"];
}
}
}
return tcell;
我正在尝试获取以下数据:
NSLog(@"1 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]]).txtDetails.text);
NSLog(@"2 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0]]).txtDetails.text);
NSLog(@"3 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:1]]).txtDetails.text);
NSLog(@"4 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:2]]).txtDetails.text);
NSLog(@"5 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:2]]).txtDetails.text);
NSLog(@"6 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:3]]).txtDetails.text);
NSLog(@"7 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:3]]).txtDetails.text);
NSLog(@"8 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:4]]).txtDetails.text);
NSLog(@"9 %@",((editContactCell*)[tblvwEditContactDetails cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:4]]).txtDetails.text);
但只有可见的行有任何文本字段,其他行返回null。

您可以在自定义单元格中实现协议,并将每个更改传递到您的tableview并手动处理:
// Cell.h
@protocol UpdateValueProtocol <NSObject>
-(void)updateValue:(id)value forKey:(NSString *)key;
@end
@interface Cell : UITableViewCell <UITextFieldDelegate>
...
@property (nonatomic, assign) UITableViewController<UpdateValueProtocol> *parent;
@end
// Cell.m
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[parent updateValue:textField.text forKey:lblTitle.text];
return YES;
}
// ParentTableView.h
@interface ParentTableView<UpdateValueProtocol>
{
NSMutableDictionary *contactDictionary;
}
// ParentTableView.m
-(void)updateValue:(id)value forKey:(NSString *)key
{
if(!contactDictionary)
contactDictionary = [NSMutableDictionary dictionary];
[contactDictionary setObject:value forKey:key];
}
不知道您dictClientDetails
的用途,但您也可以使用此代替contactDictionary
来更新值。

您还应该检查数据输入框架,例如免费的Sensible TableView框架。该框架将自动从您的数据对象生成所有单元格,并将处理从单元格读取/写入的所有数据。在我的项目中节省了大量时间。
