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;
}];
}
