Objective-C iPhone 应用程序与 MonoTouch 应用程序相比有多大

Objective-C是一种用于开发iPhone应用程序的编程语言，而MonoTouch是一种使用C#语言开发iPhone应用程序的工具。在本文中，我们将比较这两种方法的优劣，并探讨它们在开发iPhone应用程序方面的差异。

objective-c
#import 
@interface ViewController : UIViewController
@property (nonatomic, strong) UILabel *label;
@end
@implementation ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    
    self.label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 200, 50)];
    self.label.text = @"Hello, Objective-C!";
    self.label.textAlignment = NSTextAlignmentCenter;
    self.label.center = self.view.center;
    
    [self.view addSubview:self.label];
}
@end

csharp
using System;
using UIKit;
public class ViewController : UIViewController
{
    private UILabel label;
    public override void ViewDidLoad()
    {
        base.ViewDidLoad();
        label = new UILabel();
        label.Frame = new CoreGraphics.CGRect(0, 0, 200, 50);
        label.Text = "Hello, MonoTouch!";
        label.TextAlignment = UITextAlignment.Center;
        label.Center = View.Center;
        View.AddSubview(label);
    }
}
