Objective-C 字符串格式化[重复]

使用Objective-C编程语言进行字符串格式化是一项非常重要的技能。字符串格式化允许我们以一种优雅的方式将变量插入到字符串中，使得输出更加灵活和易读。在本文中，我们将学习如何使用Objective-C的字符串格式化，以及一些常见的用例。

objective-c
NSString *name = @"张三";
NSString *greeting = [NSString stringWithFormat:@"你好，%@！", name];
NSLog(@"%@", greeting);

objective-c
@interface Student : NSObject
@property (nonatomic, strong) NSString *name;
@property (nonatomic, assign) float score1;
@property (nonatomic, assign) float score2;
@property (nonatomic, assign) float score3;
@end
@implementation Student
@end

objective-c
Student *student = [[Student alloc] init];
student.name = @"李四";
student.score1 = 90.5;
student.score2 = 85.0;
student.score3 = 92.3;

objective-c
float averageScore = (student.score1 + student.score2 + student.score3) / 3;
NSString *output = [NSString stringWithFormat:@"学生%@的平均成绩为%.2f分。", student.name, averageScore];
NSLog(@"%@", output);
