其名称中包含在Objective-C

Question

我已经宣布在Objective-C项目自定义对象数调用自定义对象：

Student* student1 = [[Student alloc]init]; 
Student* student2 = [[Student alloc]init]; 
Student* student3 = [[Student alloc]init]; 
Student* student4 = [[Student alloc]init]; 
Student* student5 = [[Student alloc]init]; 
Student* student6 = [[Student alloc]init]; 

我怎么能叫他们在周期

for (int i=1; i<=6; i++) 
{ 
} ? 

Answer 1

你可以没有直接做到这一点。您可以使用数组（C风格或NSArray），然后迭代（使用从零开始的索引或for-in循环）。

例如：

NSArray* students = @[ [[Student alloc] init], 
         [[Student alloc] init], 
         [[Student alloc] init], 
         [[Student alloc] init], 
         [[Student alloc] init], 
         [[Student alloc] init], 
        ]; 
for (int i = 0; i < students.count; i++) 
{ 
    Student* student = students[i]; 
    // Do something with student 
} 
// Or: 
for (Student* student in students) 
{ 
    // Do something with student 
}
