Because the text of bar button item cannot be changed, replace it with a label,

Label does not receive click events, so it can be passed back to the button to process click events

Is a part of version 87 deleted now? Why do I feel a part is missing each time? The more sad you are, the more likely you are to delete the plot.

I also think many of them have been deleted ~

For ios custom tableviewcell, how does one use the multiple-choice delete function provided by the system?

1. Create the TableViewCell class and inherit the parent class as UITableViewCell.

1.1
"TableCell. h"

# Import
<UIKit/UIKit. h>

/**

*
Room Table Display Structure

*
/

@ Interface
TableCell: UITableViewCell {

　　　
UILabel
* TableNoLable; // table number

　　　
UIImageView
* TableImageView; // table Image

　　
UIImageView
* TableStateImageView; // Table Status Image

}

@ Property
(Nonatomic, retain) IBOutlet UILabel * tableNoLable; // table number

@ Property
(Nonatomic, retain) IBOutlet UIImageView * tableImageView; // table Image

@ Property
(Nonatomic, retain) IBOutlet UIImageView * tableStateImageView; // Table Status picture

1.2
TableCell.
M

# Import
"TableCell. h"

@ Implementation
TableCell

@ Synthesize
TableNoLable; // table number

@ Synthesize
TableImageView; // table Image

@ Synthesize
TableStateImageView; // Table Status picture

-
(Id) initWithStyle :( UITableViewCellStyle) style reuseIdentifier :( NSString
*) ReuseIdentifier {

If (self = [super initWithStyle: style reuseIdentifier: reuseIdentifier]) {

// Initialization code

}

Return self;

}

-
(Void) setSelected :( BOOL) selected animated :( BOOL) animated {

[Super setSelected: selected animated: animated];

// Configure the view for the selected state

}

-
(Void) dealloc {

[TableNoLable
Release];

[TableImageView
Release];

[Hand3ImageView
Release];

[Super dealloc];

}

@ End

1.3
Layout layout file (
Xib
File) specifies

For your own
Tabelcellview

A new Empty Xib file, which does not contain view,
Drag a UITableCell to the two icons in libriary, double-click cellview, specify the class as the cell. m file, and start editing.
