C#基本之Lambda表達式用法實例教程。本站提示廣大學習愛好者:(C#基本之Lambda表達式用法實例教程)文章只能為提供參考,不一定能成為您想要的結果。以下是C#基本之Lambda表達式用法實例教程正文
一,工程圖。

二,後果圖。

三,代碼。
RootViewController.h
#import <UIKit/UIKit.h> @interface RootViewController : UIViewController <UIGestureRecognizerDelegate> @end
RootViewController.m
#import "RootViewController.h"
@interface RootViewController ()
@end
@implementation RootViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
//增長配景圖
[self addView];
}
#pragma -mark -functions
//配景圖
-(void)addView
{
//白色的配景圖
UIView *parentView=[[UIView alloc]initWithFrame:CGRectMake(50, 100, 200, 200)];
parentView.backgroundColor=[UIColor redColor];
[self.view addSubview:parentView];
[parentView setUserInteractionEnabled:YES];
//挪動的手勢
UIPanGestureRecognizer *panRcognize=[[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(handlePan:)];
panRcognize.delegate=self;
[panRcognize setEnabled:YES];
[panRcognize delaysTouchesEnded];
[panRcognize cancelsTouchesInView];
[parentView addGestureRecognizer:panRcognize];
}
#pragma UIGestureRecognizer Handles
- (void)handlePan:(UIPanGestureRecognizer *)recognizer {
NSLog(@"--挪動的手勢-----");
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
以上代碼是有關Android法式開辟之給配景圖加上挪動的手勢的全體內容,願望對年夜家有所贊助!
