如何使用Iphone上的Objective-C在控制器中初始化自定义类/对象

#import "CustomClass.h"

CustomClass *customObject = [[CustomClass alloc] init];

[customObject performCustomAction];

// CustomClass.h
#import<Foundation/Foundation.h>

@interface CustomClass : NSObject

@property (nonatomic, strong) NSString *customProperty;

- (void)performCustomAction;

@end

// CustomClass.m
#import "CustomClass.h"

@implementation CustomClass

- (void)performCustomAction {
    NSLog(@"Custom action performed!");
}

@end

// ViewController.m
#import "ViewController.h"
#import "CustomClass.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    CustomClass *customObject = [[CustomClass alloc] init];
    customObject.customProperty = @"Hello, World!";
    [customObject performCustomAction];
}

@end
