mac 自定义NSTableCellView

---

1新建空项目,参考:http://blog.youkuaiyun.com/zfphp/article/details/51153144
2 选中MainWindowController.xib,在window上添加NSTableView控件，选中NSTableView，设置Content Mode为View Based.

3创建一个empty的xib文件命名为CustomCellView.xib
4往CustomCellView中拖入tablecellview，可以去掉不需要的控件，添加上自己需要的控件,将cell的identifier改为customCell

5创建一个CustomCell类，继承NSTableCellView,将xib内cell的Class改为CustomCell，然后就可以连线了.

这样cell的工作就完成了

6将TableView自身与TableView的datasource和delegate都连接到appdelegate里面.注意一共需要连三条线

7 MainWindowController.m代码如下:

#import "MainWindowController.h"
#import "CustomCell.h"
@interface MainWindowController ()

@end

@implementation MainWindowController

- (void)windowDidLoad {
    [super windowDidLoad];

    // Implement this method to handle any initialization after your window controller's window has been loaded from its nib file.


    self.contents = [NSMutableArray arrayWithObjects:@"a",@"b", nil];
}

-(NSString *)windowNibName{
    return @"MainWindowController";
}
-(void)awakeFromNib{
    [self.tableView registerNib:[[NSNib alloc] initWithNibNamed:@"CustomCellView" bundle:nil] forIdentifier:@"customCell"];
}


#pragma mark table datasource
-(NSInteger)numberOfRowsInTableView:(NSTableView *)tableView{
    return self.contents.count;
}

-(id)tableView:(NSTableView *)tableView objectValueForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row{
    return [self.contents objectAtIndex:row];
}

#pragma mark table delegate
-(NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row{
    /*
    if(!_nib){
        _nib = [[NSNib alloc] initWithNibNamed:@"CustomCellView" bundle:nil];
        [tableView registerNib:_nib forIdentifier:@"customCell"];
    }*/
    CustomCell *cellView = [tableView makeViewWithIdentifier:@"customCell" owner:self];

    cellView.title.stringValue = @"aaa";
    cellView.subTitle.stringValue = @"bbb";
    return cellView;
}
@end
