先在FirstViewController.h裡面呼叫

#import "FirstViewController.h"
#import "SecondViewController.h"
@interface FirstViewController ()

@end

@implementation FirstViewController


- (IBAction)pressNext:(UIButton *)sender {
//    SecondViewController * vc =[self.storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"];

    //Prepare the next page
    SecondViewController * vc =(SecondViewController*)[self.storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"];
    //Show the next page,
    //animated means show animation YES or NO?
    //completion:nil means dont's do anything.

    [self presentViewController:vc animated:YES completion:nil];

}

@end

然後再到去清除viewcontroller

//  SecondViewController.m

#import "SecondViewController.h"

@interface SecondViewController ()

@end

@implementation SecondViewController

- (IBAction)goback:(UIButton *)sender {

[self dismissViewControllerAnimated:YES completion:nil];
}
@end

//  FirstViewController.m


#import "FirstViewController.h"
#import "SecondViewController.h"
@interface FirstViewController ()

@end

@implementation FirstViewController

-(void) viewDidLoad{
    [super viewDidLoad];
    NSLog(@"第一個viewcontroller 正經歷 viewDidLoad 階段");
}

-(void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    NSLog(@"第一個viewcontroller 正經歷 viewWillAppear 階段");

}

-(void) viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];
    NSLog(@"第一個viewcontroller 正經歷 viewDidAppear 階段");

}

-(void) viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];
    NSLog(@"第一個viewcontroller 正經歷 viewWillDisappear 階段");

}

-(void) viewDidDisappear:(BOOL)animated
{
    [super viewDidDisappear:animated];
    NSLog(@"第一個viewcontroller 正經歷 viewDidDisappear 階段");
}


- (IBAction)pressNext:(UIButton *)sender {
//    SecondViewController * vc =[self.storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"];

    //Prepare the next page
    SecondViewController * vc =(SecondViewController*)[self.storyboard instantiateViewControllerWithIdentifier:@"SecondViewController"];
    //Show the next page,
    //animated means show animation YES or NO?
    //completion:nil means dont's do anything.

    [self presentViewController:vc animated:YES completion:nil];
}
