How to read data from UITextField located in custom UITableView - ios

Question

First of all I know there are several more titles looks like same. I have checked them but what I ask is a specific problem.
What I want to do: Created Login table which includes email and password. UITextfields in UITableView. Just want to take those data into some NSString variable pointers for further process.
I have a Custom Cell Class named CustomCell, as below:
#import "CustomCell.h"
#import "QuartzCore/QuartzCore.h"
#implementation CustomCell
#synthesize textfield;
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
textfield = [[UITextField alloc] initWithFrame:CGRectMake(5, 7, 160, 20)];
textfield.textColor = [UIColor blackColor];
textfield.font = [UIFont systemFontOfSize:14];
[self.contentView addSubview:textfield];
}
return self;
}
- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
[super setSelected:NO animated:NO];
// Configure the view for the selected state.
}
- (void)dealloc {
[super dealloc];
}
#end
And I have ViewController where I use the custom table below you may see my tableView cellForRowAtIndex method.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
[tableView.layer setCornerRadius:10.0];
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];}
switch (indexPath.row) {
case 0:
cell.textfield.placeholder = #"Email";
break;
case 1:
cell.textfield.placeholder = #"Password";
cell.textfield.tag = 0;
break;
}
return cell;
}
And lastly below in same class I am trying to read email & password with
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection:0];
CustomCell *cell = [tableView cellForRowAtIndexPath:indexPath]; // ERROR!!!
NSString *userpassword = cell.textfield.text;
Error: Unknown receiver type tableView:
Attention in same line:
ClassMethod +cellforrowatindexpath not found return type defaults to id.
Did you see what I am doing wrong?

Answer 1

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection:0];
CustomCell *cell = (CustomCell *)[tableView cellForRowAtIndexPath:indexPath]; // Add This instead
NSString *userpassword = cell.textfield.text;

Answer 2

Yu can't use tableView outside the datasource and delegate methods. What's the name of your tableview in your interface definition? Use that one.

Answer 3

Is your ViewController inheriting UIView or UITableViewController? This is assuming you are calling tableView on the same controller as the Table View.
