Question

I have a UITableView class that i am calling in another class

 MyPocketTableView * myPocketTableView = [[MyPocketTableView alloc]initWithFrame:CGRectMake(85, 153, 235, 250) style:UITableViewStyleGrouped]; 

However, the init method in the UITableViewClass does not let me do this.

@implementation MyPocketTableView

- (id) initWithFrame:(CGRect)frame style:(UITableViewStyle)style {
    self = [super initWithFrame:frame];
    self = [super initWithStyle:style]

    if (self) {

        //[self setFrame:CGRectMake(85, 153, 235, 250)];
        self.dataSource = self;
        self.delegate = self;

    }
    return self;
}

I cannot add style : (UITableViewStyle) style on to the init method definition, nor can i do the self = [super initWithStyle:style] because it complains saying

No visible @interface for ‘UITableView’ declares the selector initWithStyle.

The default init method that was there when the class was created was - (id) initWithFrame:(CGRect)frame. MyPocketTableView is a sub class of UITableView.

  @interface MyPocketTableView : UITableView <UITableViewDataSource,UITableViewDelegate>

You need to set the interface to UITableViewController, then use initWithStyle:.

Also, in doing the following, there is no need to set the UITableView protocol delegates

@interface MyPocketTableView : UITableViewController

Then you can call:

MyPocketTableView * myPocketTableView = [[MyPocketTableView alloc] initWithStyle:UITableViewStyleGrouped];

As well as the following:

- (id) initWithStyle:(UITableViewStyle)style 
{
    self = [super initWithStyle:style];
    if (self) {
        [self setFrame:CGRectMake(85, 153, 235, 250)];
    }
    return self;
}

You can also use the following (example) custom method: The key being you are calling:

self = [super initWithStyle:UITableViewStyleGrouped];

- (id) initWithSomeCustomMessage:(NSString*)message
{
    self = [super initWithStyle:UITableViewStyleGrouped];
    if (self) {
        [self setFrame:CGRectMake(85, 153, 235, 250)];
        self.customMessage = message;
    }
    return self;
}
