这里有一个:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button addTarget:self 
           action:@selector(aMethod:)
 forControlEvents:UIControlEventTouchUpInside];
[button setTitle:@"Show View" forState:UIControlStateNormal];
button.frame = CGRectMake(80.0, 210.0, 160.0, 40.0);
[view addSubview:button];

你可以在你的ViewDidLoad方法中实现它:

continuebtn = [[UIButton alloc]initWithFrame:CGRectMake(10, 100, view1.frame.size.width-20, 40)];
    [continuebtn setBackgroundColor:[UIColor grayColor]];
    [continuebtn setTitle:@"Continue" forState:UIControlStateNormal];
    continuebtn.layer.cornerRadius = 10;
    continuebtn.layer.borderWidth =1.0;
    continuebtn.layer.borderColor = [UIColor blackColor].CGColor;
    [continuebtn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    [continuebtn addTarget:self action:@selector(continuetonext) forControlEvents:UIControlEventTouchUpInside];
    [view1 addSubview:continuebtn];

其中continuetonext为:

-(void)continuetonext
{
    GeneratePasswordVC *u = [[GeneratePasswordVC alloc]init];
    [self.navigationController pushViewController:u animated:YES];
}

UIButton *custombutton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[custombutton addTarget:self
                 action:@selector(aMethod:)
       forControlEvents:UIControlEventTouchUpInside];
[custombutton setTitle:@"Click" forState:UIControlStateNormal];
custombutton.frame = CGRectMake(80.0, 110.0, 160.0, 40.0);
custombutton.titleLabel.textColor = [UIColor colorWithRed: 2.0f/255.0f green: 155.0f/255.0f blue: 213.0f/255.0f  alpha:1];
 [custombutton setImage:[UIImage imageNamed:@"hh.png"] forState:UIControlStateNormal];
 [view addSubview:custombutton];

UIButton *button=[UIButton buttonWithType:UIButtonTypeCustom];

[button setTitle:@"Click" forState:UIControlStateNormal];

[button setTitleColor:[UIColor blackColor]forState:UIControlStateNormal];

button.frame=CGRectMake(self.view.frame.origin.x+10,self.view.frame.size.height/2, self.view.frame.size.width-20, self.view.frame.size.height-500);

 button.titleLabel.font=[UIFont fontWithName:@"Helvetica" size:20];

[button addTarget:selfaction:@selector(aMethod)forControlEvents:UIControlEventTouchUpInside];

[button setBackgroundColor:[UIColor grayColor]];

[self.view addSubview:button];

- (void)viewDidLoad {
    [super viewDidLoad];
    [self addMyButton];   // Call add button method on view load
}

- (void)addMyButton{    // Method for creating button, with background image and other properties

    UIButton *playButton = [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
    playButton.frame = CGRectMake(110.0, 360.0, 100.0, 30.0);
    [playButton setTitle:@"Play" forState:UIControlStateNormal];
    playButton.backgroundColor = [UIColor clearColor];
    [playButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal ];
    UIImage *buttonImageNormal = [UIImage imageNamed:@"blueButton.png"];
    UIImage *strechableButtonImageNormal = [buttonImageNormal stretchableImageWithLeftCapWidth:12 topCapHeight:0];
    [playButton setBackgroundImage:strechableButtonImageNormal forState:UIControlStateNormal];
    UIImage *buttonImagePressed = [UIImage imageNamed:@"whiteButton.png"];
    UIImage *strechableButtonImagePressed = [buttonImagePressed stretchableImageWithLeftCapWidth:12 topCapHeight:0];
    [playButton setBackgroundImage:strechableButtonImagePressed forState:UIControlStateHighlighted];
    [playButton addTarget:self action:@selector(playAction:) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:playButton];  
}

如果愿意，可以将创建者实例放入循环中，并从数组中动态添加名称。
