模态视图在ios开发中用处非常广

ios开发中。在当前视图上再弹出一个视图(模态视图)。实现一个简单的多视图应用,以下给大家写个demo

一 。

//
//  AppDelegate.h
//  模态视图
//

#import <UIKit/UIKit.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate>

@property (strong, nonatomic) UIWindow *window;


@end

//
//  AppDelegate.m
//  模态视图


#import "AppDelegate.h"

@interface AppDelegate ()

@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    return YES;
}

- (void)applicationWillResignActive:(UIApplication *)application {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

- (void)applicationDidEnterBackground:(UIApplication *)application {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

- (void)applicationWillEnterForeground:(UIApplication *)application {
    // Called as part of the transition from the background to the inactive state; here you can undo many of the changes made on entering the background.
}

- (void)applicationDidBecomeActive:(UIApplication *)application {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

- (void)applicationWillTerminate:(UIApplication *)application {
    // Called when the application is about to terminate. Save data if appropriate. See also applicationDidEnterBackground:.
}

@end

//
//  ViewController.h
//  模态视图


#import <UIKit/UIKit.h>

@interface ViewController : UIViewController


@end

//
//  ViewController.m
//  模态视图
//


#import "ViewController.h"
#import "ModalViewController.h"
@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    self.view.backgroundColor = [UIColor groupTableViewBackgroundColor];
    
    //加入弹出模态视图按钮
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    btn.frame = CGRectMake(120, 220, 80, 40);
    [btn setTitle:@"模态视图" forState:UIControlStateNormal];
    [btn addTarget:self action:@selector(btnTouch) forControlEvents:UIControlEventTouchUpInside];
    
    [self.view addSubview:btn];
    // Do any additional setup after loading the view, typically from a nib.
}

-(void)btnTouch
{
    ModalViewController *modalView = [[ModalViewController alloc]init];
    modalView.modalPresentationStyle = UIModalTransitionStyleCoverVertical;
    [self presentViewController:modalView animated:YES completion:^{
      
    }];
    
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

//
//  ModalViewController.h
//  模态视图


#import <UIKit/UIKit.h>

@interface ModalViewController : UIViewController

@end

//
//  ModalViewController.m
//  模态视图
//
/

#import "ModalViewController.h"

@interface ModalViewController ()

@end

@implementation ModalViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    
    self.view.backgroundColor = [UIColor purpleColor];
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    btn.frame = CGRectMake(130, 50, 60, 20);
    
    [btn setTitle:@"返回" forState:UIControlStateNormal];
    
    [btn addTarget:self action:@selector(btnTouchBack) forControlEvents:UIControlEventTouchUpInside];
    
    [self.view addSubview:btn];
    
    // Do any additional setup after loading the view.
}


-(void)btnTouchBack
{
    [self dismissViewControllerAnimated:YES completion:^{
        
    }];
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

/*
#pragma mark - Navigation

// In a storyboard-based application, you will often want to do a little preparation before navigation
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
    // Get the new view controller using [segue destinationViewController].
    // Pass the selected object to the new view controller.
}
*/

@end
