How to use UINib to instantiate and use custom UITableViewCells
Solution 1
- Create your xib file with a UITableViewCell as the top-level object. This is called Cell.xib
- Create a UINib object based on this file
- Register the UINib with the table view (typically in viewDidLoad of your table view controller subclass).
Steps 2 and 3 can be combined, so you would use the following line in viewDidLoad:
[self.tableView registerNib:[UINib nibWithNibName:@"Cell" bundle:nil] forCellReuseIdentifier:@"Cell"];
Then, in cellForRowAtIndexPath, if you want one of the cells from the nib, you dequeue it:
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"Cell"];
This either creates a new instance from the nib, or dequeues an existing cell.

@jrturtons answer is correct but unfortunately there's a bug in iOS 5 (fixed in iOS 6) in conjunction with VoiceOver: rdar://11549999. The following category on UITableView
fixes the issue. Just use -fixedDequeueReusableCellWithIdentifier:
instead of the normal dequeueReusableCellWithIdentifier:
. Of course, the NIB must be registered using
[self.tableView registerNib:[UINib nibWithNibName:@"Cell" bundle:nil] forCellReuseIdentifier:@"Cell"];
before (in -viewDidLoad
).
UITableView+Workaround.m:
@implementation UITableView (Workaround)
- (id)fixedDequeueReusableCellWithIdentifier:(NSString *)identifier {
id cell = [self dequeueReusableCellWithIdentifier:identifier];
if (!cell) {
// fix for rdar://11549999 (registerNib… fails on iOS 5 if VoiceOver is enabled)
cell = [[[NSBundle mainBundle] loadNibNamed:identifier owner:self options:nil] objectAtIndex:0];
}
return cell;
}

how would i use UINibs to instantiate and use a UITableViewCell for a tableview in iOS5.0. I know there is a registerNib:forCellReuseIdentifier: in iOS5.0 that also needs to be used, but am not sure how to use it
Thanks in advance for any help on this

SimplyKiwi almost 12 yearsI actually just implemented the Cell Reuse Identifier myself and it works quite nicely!

Steven Fisher over 11 yearsI've read about this bug a number of times, but have never experienced it — even on iOS 5.0 when running VoiceOver. I believe the actual issue to be far more complicated than this.

Satyam about 11 yearsOn loading the cell, I want to customize the background color programmatically (because the bg color is a pattern image). Is it possible?

jrturton about 11 years@Satyamsvv Yes, use awakeFromNib in the cell subclass. If its more complicated than that, ask a new question.
