initWithFrame : reuseIdentifier : is deprecated

Take a look at this Apple's page

Here Red-Highlighted Functions and Properties will be Removed in Future by Apple in upcoming SDK.

so that we should avoid them while creating App.

Because we need longterm project which should run without crash.

a deprecated method means it has been replaced/retired but is still valid in current version of the language. it should be avoided and can cause problems/errors. check the documentation which should list an alternative method you can use.

Here you should use the method

 - initWithStyle:reuseIdentifier: 

Then your if loop would look like this

if (cell == nil) {    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault               reuseIdentifier:CellIdentifier] autorelease];}

This problem appears in Beginning IOS 5 Development by Mark, Nutting and La Marche. Some readers may come here from that book where the deprecated code appears on page 265. They may assume the fault is theirs!

cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: sectionsTableIdentifier] autorelease];

needs to be replaced by (as the contributors above point out)

cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier: sectionsTableIdentifier];

Notice that I have dropped the autorelease as well because Auto Reference Counting does not like it!

Hope this helps.

Use this code:

cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault                                  reuseIdentifier:CellIdentifier] autorelease];
