initWithFrame:reuseIdentifier:
Initializes and returns a table cell object.
Declaration
- (id) initWithFrame:(CGRect) frame reuseIdentifier:(NSString *) reuseIdentifier;Parameters
- frame:
The frame rectangle of the cell. Because the table view automatically positions the cell and makes it the optimal size, you can pass in
CGRectZeroin most cases. However, if you have a custom cell with multiple subviews, each with its own autoresizing mask, you must specify a non-zero frame rectangle; this allows the table view to position the subviews automatically as the cell changes size. - reuseIdentifier:
A string used to identify the cell object if it is to be reused for drawing multiple rows of a table view. Pass
nilif the cell object is not to be reused.
Return Value
An initialized UITableViewCell object or nil if the object could not be created.
Discussion
This method is the designated initializer for the class. The reuse identifier is associated with those cells (rows) of a table view that have the same general configuration, minus cell content. In its implementation of tableView(_:cellForRowAt:), the table view’s delegate calls the UITableView method dequeueReusableCell(withIdentifier:), passing in a reuse identifier, to obtain the cell object to use as the basis for the current row.
