mac OS开发Label控件使用及显示

1  设置Label自动换行：在中将layout选项设置为wraps

2  label显示字符串,  使用stringValue实现

 @property (strong) IBOutletNSTextField *DeviceVerNum;

self.DeviceVerNum.stringValue = @"Please connect your headset to yourcomputer";

显示字符串+数字：使用NSString stringWithFormat

NSString* DeviceVersionStr;

 

 DeviceVersionStr=[NSString stringWithFormat:@"The device version is:%s,it will update to:%s",DeviceVersion,HexVersion];

 [_DeviceVerNum setStringValue:(DeviceVersionStr)];

#import <Foundation/Foundation.h>

 

int main(){

   NSString* str;

   str = [NSString stringWithFormat:@"your height is %d feet, %d inches.",5,11];

//   NSLog(@"%@",str);

   NSLog(@"%@",str);

   

   NSString* str1 ;

   str1 = @"MAC";

   //指定NSString的实例来创建字符串

   NSString* str2 ;

   str2 = [NSString stringWithFormat:@"%@ PRO",str1];

   NSLog(@"%@",str2);

   

   //指定整数，创建字符串

   int i = 80;

   NSString* str3;

   str3 = [NSString stringWithFormat:@"%d %%",i];

   NSLog(@"%@",str3);//这样str3就变为80%

   

   NSString* str4;

   str4 = [NSString stringWithFormat:@"0x%x",i];

   NSLog(@"%@",str4);

   

   return 0;
