To possition button You need to change the button's origins x and y. Look at the sample code which I wrote below and comments.
定位按钮 您需要更改按钮的原点 x 和 y。看看我在下面写的示例代码和注释。
You can do it like this:
你可以这样做：
-(void)awakeFromNib {
//Start from bottom left corner
int x = 100; //possition x
int y = 100; //possition y
int width = 130;
int height = 40;
NSButton *myButton = [[[NSButton alloc] initWithFrame:NSMakeRect(x, y, width, height)] autorelease];
[[windowOutlet contentView] addSubview: myButton];
[myButton setTitle: @"Button title!"];
[myButton setButtonType:NSMomentaryLightButton]; //Set what type button You want
[myButton setBezelStyle:NSRoundedBezelStyle]; //Set what style You want
[myButton setTarget:self];
[myButton setAction:@selector(buttonPressed)];
}
-(void)buttonPressed {
NSLog(@"Button pressed!");
//Do what You want here...
}
** WindowOutletis window so don't forget to IBOutlet it.
** WindowOutlet是窗口所以不要忘记 IBOutlet 它。

All buttons are controls and all controls are views, so see, in order:
所有按钮都是控件，所有控件都是视图，因此请按顺序查看：
