IOS UI 第四篇：基本UI

ViewController 应用

 

再第一个XIB页面创建另一个XIB页面，并且通过按钮调用它

 

 

- (IBAction)GoSecond:(id)sender {
    secondViewController *secVC = [[secondViewController alloc] initWithNibName:@"secondViewController" bundle:nil];

    secVC.modalTransitionStyle = UIModalPresentationPageSheet;

    [self presentViewController:secVC animated:YES completion:^{
        NSLog(@"success ");
    }];
}

 

在第二个XIB页面创建一个按钮，按钮PRESS返回第一个页面

 

 

- (IBAction)Backfirst:(id)sender {
    [self dismissViewControllerAnimated:YES completion:^{
        NSLog(@"dismiss");
    }];
}

 

 

创造生命周期函数：

 

-(void)viewWillAppear:(BOOL)animated{
    [super viewWillAppear:animated];
    NSLog(@"view will appear");
}
-(void)viewDidAppear:(BOOL)animated{
    [super viewDidAppear:animated];
    NSLog(@"view did appear");
}
-(void)viewWillDisappear:(BOOL)animated{
    [super viewWillDisappear:animated];
    NSLog(@"view will disappear");
}
-(void)viewDidDisappear:(BOOL)animated{
    [super viewDidDisappear:animated];
    NSLog(@"view did disappear");
}

 

 

页面切换方法：

 

       secVC.modalTransitionStyle = UIModalPresentationPageSheet;

    UIModalPresentationFullScreen = 0,
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_3_2
    UIModalPresentationPageSheet,
    UIModalPresentationFormSheet,
    UIModalPresentationCurrentContext,
#endif
#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_7_0
    UIModalPresentationCustom,
    UIModalPresentationNone = -1,   

 

 

 

 

做成如下图片，类型：

 

 

 

 

主视图代码：

 

#import "UserModel.h"
@interface Xib_1 : UIViewController
@property (nonatomic, weak) UserModel *model;
-(void)sentRegistMessage:(UserModel *)user;
@end

 

 

- (IBAction)FirstButton:(id)sender {
    Xib_2 *xib2 = [[Xib_2 alloc] initWithNibName:@"Xib_2" bundle:nil];
    xib2.parentVC = self;
    xib2.modalTransitionStyle = UIModalPresentationPageSheet;
    [self presentViewController:xib2 animated:YES completion:^{
        
    }];
}

 

-(void)sentRegistMessage:(UserModel *)user{
    self.Label_1.text = [NSString stringWithFormat:@"恭喜，注册成功，用户名：%@，密码：%@，请牢记，谢谢合作。", user.name, user.pass];
    self.Label_1.numberOfLines = 0;
}

 

 

XIB2：

 

#import "Xib_1.h"

@interface Xib_2 : UIViewController
@property (nonatomic, weak) Xib_1 *parentVC;
@end

 

- (IBAction)Button_submit:(id)sender {
    UserModel *model = [[UserModel alloc] init];
    model.name = _nameLabel.text;
    model.pass = _passLabel.text;
    [self.parentVC sentRegistMessage:model];
    [self dismissViewControllerAnimated:YES completion:^{
    }];
}

 

 

UserModel:

 

@interface UserModel : NSObject
@property (nonatomic, copy)NSString *name;
@property (nonatomic, copy)NSString *pass;
@end

 

用协议可以限制权限：

 

 

 

小球移动的动画：

 

 

@implementation QFAppDelegate{
    UIView *redView;
}

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    //动画
    redView=[[UIView alloc]initWithFrame:CGRectMake(100, 100, 100, 100)];
    redView.backgroundColor=[UIColor redColor];
    [self.window addSubview:redView];
   
    UIButton *button=[UIButton buttonWithType:UIButtonTypeCustom];
    [button setTitle:@"开始动画" forState:UIControlStateNormal];
    [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [button addTarget:self action:@selector(startAnim:) forControlEvents:UIControlEventTouchUpInside];
    button.frame=CGRectMake(100, 400, 100, 44);
    [self.window addSubview:button];

    
    self.window.backgroundColor = [UIColor whiteColor];
    [self.window makeKeyAndVisible];
    return YES;
}
-(void)startAnim:(id)sender{
    [UIView animateWithDuration:1 animations:^{
        redView.frame=CGRectMake(100, 300, 150, 150);//大小位置
        redView.transform=CGAffineTransformMakeRotation(M_PI_4);//角度
    } completion:^(BOOL finished) {
        if (finished) {
            [UIView animateWithDuration:2 animations:^{
                redView.transform=CGAffineTransformIdentity;//把变形还原
                redView.frame=CGRectMake(100, 100, 100, 100);
            }];
        }
    }];
}

 

 

如图，做一个三本书旋转的动画例子：

 

 

 

通过animateWithDuration:animations方法来实现动画旋转效果，方便，快捷！

 

 

代码如下：

 

- (void)viewDidLoad
{
    
    [super viewDidLoad];
    [self begin];
    // Do any additional setup after loading the view from its nib.
}

-(void)begin
{
    imageView_3 = [[UIImageView alloc] initWithFrame:CGRectMake(30, 50, 100, 150)];
    imageView_2 = [[UIImageView alloc] initWithFrame:CGRectMake(200, 50, 100, 150)];
    imageView_1 = [[UIImageView alloc] initWithFrame:CGRectMake(80, 110, 140, 200)];

    imageView_1.image = [UIImage imageNamed:[NSString stringWithFormat:@"1.jpg"]];
    imageView_2.image = [UIImage imageNamed:[NSString stringWithFormat:@"2.jpg"]];
    imageView_3.image = [UIImage imageNamed:[NSString stringWithFormat:@"3.jpg"]];

    [_Subview addSubview:imageView_1];
    [_Subview addSubview:imageView_2];
    [_Subview addSubview:imageView_3];
    [_Subview bringSubviewToFront:imageView_1];

}
- (IBAction)PrePress:(id)sender {
    [UIView animateWithDuration:1 animations:^{
        [_Subview sendSubviewToBack:imageView_3];
        imageView_1.frame = CGRectMake(30, 50, 100, 150);
        imageView_2.frame = CGRectMake(80, 110, 140, 200);
        imageView_3.frame = CGRectMake(200, 50, 100, 150);
    }completion:^(BOOL finished) {
        //imageView_2.frame = CGRectMake(30, 50, 100, 150);
        [_Subview bringSubviewToFront:imageView_2];
        UIImageView *tmp;
        tmp = imageView_1;
        imageView_1 = imageView_2;
        imageView_2 = imageView_3;
        imageView_3 = tmp;
    }];

}
- (IBAction)NextPress:(id)sender {
    
    [UIView animateWithDuration:1 animations:^{
        [_Subview sendSubviewToBack:imageView_2];
        imageView_1.frame = CGRectMake(200, 50, 100, 150);
        imageView_2.frame = CGRectMake(30, 50, 100, 150);
        imageView_3.frame = CGRectMake(80, 110, 140, 200);
    }completion:^(BOOL finished) {
        imageView_2.frame = CGRectMake(30, 50, 100, 150);
        [_Subview bringSubviewToFront:imageView_3];
        UIImageView *tmp;
        tmp = imageView_1;
        imageView_1 = imageView_3;
        imageView_3 = imageView_2;
        imageView_2 = tmp;
    }];
}
