以下是以编程方式创建单选按钮的示例代码：

//create the radio button prototype
NSButtonCell *proto = [[NSButtonCell alloc] init];
[proto setTitle:@"Options"];
[proto setButtonType: NSRadioButton];

//define the matrix size where you'll put the radio buttons
NSRect matrixRect = NSMakeRect(20.0,20.0,125.0,125.0);

//define the matrix specifying that it will contain radio buttons of
//prototype "proto" defined above, and that it will have 3 radio buttons 
//arranged on 1 column
NSMatrix *matrix = [[NSMatrix alloc] initWithRect: matrixRect
                                     mode: NSRadioModeMatrix
                                     prototype: (NSCell *)proto
                                     numberOfRows:3 numberOfColumns:1];

//this assumes that you connected the window object to an outlet
[[windowOutlet contentView] addSubview: matrix];

//set the radio buttons' titles by getting references to the matrix's cells
NSArray *cells = [matrix cells];
[[cells objectAtIndex:0] setTitle:@"Option 1"];
[[cells objectAtIndex:1] setTitle:@"Option 2"];
[[cells objectAtIndex:2] setTitle:@"Option 3"];

[proto release];
[matrix release];

玩得开心！是的，这取自此处，但我添加了一些个人评论来解释该过程。

Here's a sample code for creating radio buttons programmatically:

//create the radio button prototype
NSButtonCell *proto = [[NSButtonCell alloc] init];
[proto setTitle:@"Options"];
[proto setButtonType: NSRadioButton];

//define the matrix size where you'll put the radio buttons
NSRect matrixRect = NSMakeRect(20.0,20.0,125.0,125.0);

//define the matrix specifying that it will contain radio buttons of
//prototype "proto" defined above, and that it will have 3 radio buttons 
//arranged on 1 column
NSMatrix *matrix = [[NSMatrix alloc] initWithRect: matrixRect
                                     mode: NSRadioModeMatrix
                                     prototype: (NSCell *)proto
                                     numberOfRows:3 numberOfColumns:1];

//this assumes that you connected the window object to an outlet
[[windowOutlet contentView] addSubview: matrix];

//set the radio buttons' titles by getting references to the matrix's cells
NSArray *cells = [matrix cells];
[[cells objectAtIndex:0] setTitle:@"Option 1"];
[[cells objectAtIndex:1] setTitle:@"Option 2"];
[[cells objectAtIndex:2] setTitle:@"Option 3"];

[proto release];
[matrix release];

Have fun! Yes, this is taken from here, but i added some personal comments to explain the process.

摘自此处：

单选按钮实际上是按钮单元格的矩阵。独家的
选择性是矩阵的一个属性。

要以编程方式创建按钮单元矩阵，您可以执行完全相同的操作
IB 根据您的输入以编程方式执行操作。例如
创建一个 NSMatrix 实例，将其单元格原型设置为 NSButtonCell，设置
通过其公共方法（相同的 IB
使用），并设置原型纽扣电池和/或所有的属性
包含纽扣电池。
