Objective-C UIButton网格生成 [英] Objective-C UIButton Grid Generation

问题描述

可可领主-我需要帮助！

我正在编写我的第一个应用程序（游戏），并且试图在核心框架和UIKit。我的游戏包含一个由我手动创建的UIButtons制成的5 x 8木板（！）。当我更改行为时，将更新大量的PItA。我曾经尝试过使用可变数组和UIButton生成器，但我仍然对此感到非常恐惧，而且在使事情正常进行方面一直做不到很大的努力。

该按钮存储其状态，价值，所有者和原点。我目前有A，B，C，D，E重新表示列，对行表示1-8。这些按钮为62x62，在网格的两侧具有1像素的边距，在按钮之间具有2像素的缓冲区和边距。

有人可以帮助我从一个我为每个按钮指定标签，值等...并以编程方式吐出网格的类中得到一个漂亮的小数组生成器吗？ / p>

按钮示例：

 -（IBAction）按钮A1：（id）发件人{
 UIButton * theButton =（UIButton *）sender; 
 theButton.titleLabel.font = [UIFont fontWithName：@ Gotham Rounded size：22]; 
 NSString * Title = theButton.titleLabel.text; 
 
 if（tapA1！= 1）{
 
 [theButton setAlpha：1.0]; 
 
 tapSum ++; 
 tapA1 = 1; 
 
 [theButton setTitle：@ A1 forState：UIControlStateNormal]; 
 NSLog（@从％@：\n\nSum收到的新闻是％i.\n，标题，tapSum）； 
 [theButton setBackgroundImage：[UIImage imageNamed：@ red-dot.png] forState：UIControlStateNormal]; 
 
 
 
} 
否则，如果（tapA1 == 1）
 {
 [theButton setAlpha：0.3]; 
 
 tapA1 = 0; 
 tapSum--; 
 
 NSLog（@从％@：\n\nSum收到的新闻是％i.\n，标题，tapSum）； 
} 
  

谢谢！

解决方案

您可以像这样创建GRID：-

  #define WIDTH 62 
＃定义高度62 
＃定义填充3 
＃定义NUMBEROFBUTTONSINAROW 8 
＃定义X 100 
＃定义Y 100 
＃定义总数40 
 
 NSMutableArray * array = [[NSMutableArray alloc] init]; 
 
 for（int i = 0; i< TOTALBUTTONS; i ++）
 {
 UIButton * btnClick = [UIButton buttonWithType：UIButtonTypeCustom]; 
 [btnClick setImage：[UIImage imageNamed：@ ship.jpg] forState：UIControlStateNormal]; 
 [btnClick setFrame：CGRectMake（X +（（WIDTH + PADDING）*（i％NUMBEROFBUTTONSINAROW）），Y +（HEIGHT + PADDING）*（i / NUMBEROFBUTTONSINAROW），WIDTH，HEIGHT）]； 
 [btnClick addTarget：self操作：@selector（btnTapped :) forControlEvents：UIControlEventTouchUpInside]; 
 btnClick.tag = i +1; 
 [self.view addSubview：btnClick]; 
 
 [array addObject：btnClick]; 
} 
  

最后是按钮动作：-

 -（void）btnTapped：（id）sender 
 {
 
 NSLog（@ Button Clicked％d，（（ UIButton *）sender）.tag）; 
} 
  

您可以按标记值访问按钮。该数组不是必需的。
如果需要，可以按数组访问它。

或者，您可以创建一个将所有按钮自定义与之关联的类，并将该类对象存储在Array中，只有稍后才能访问。在这种情况下，按钮实现将在类中。

Lords of Cocoa - I need assistance!

I'm coding up my first app (a game) and I'm trying to do the entire thing in the Core Frameworks and UIKit. My game involves a 5 x 8 board made from UIButtons that I've been creating manually (!). A massive PItA to update when I change the behaviour of one. I've tried using a mutable array and a UIButton generator but I'm terrible at this stuff still and I have been very unsuccesful in getting thing working.

The button stores it's state, a worth, an owner, and an origin. I currently have A,B,C,D,E reoresenting the columns and 1-8 for the rows. The buttons are 62x62 with a 1 pixel margin on either side of the grid and 2 pixel buffer and margin between the buttons.

Can someone help me get a nice little array generator from a class where I specify the tags, values etc... for each button and spit out the grid programatically?

Button Sample:

    -(IBAction) buttonA1:(id)sender {
UIButton *theButton = (UIButton *)sender;
theButton.titleLabel.font = [UIFont fontWithName:@"Gotham Rounded" size:22];
NSString *Title = theButton.titleLabel.text;

if (tapA1 != 1) {

    [theButton  setAlpha:1.0];

    tapSum++;
    tapA1 = 1;

    [theButton setTitle: @"A1" forState: UIControlStateNormal];
    NSLog(@"Press recieved from %@:\n\nSum is %i.\n", Title, tapSum);
    [theButton setBackgroundImage:[UIImage imageNamed:@"red-dot.png"] forState:UIControlStateNormal];



}
else if (tapA1 == 1)
{
    [theButton  setAlpha:0.3];

    tapA1 = 0;
    tapSum--;

    NSLog(@"Press recieved from %@:\n\nSum is %i.\n", Title, tapSum);
}

Thanks in advance!

解决方案

Well You Can Create a GRID Like this:-

#define WIDTH 62
#define HEIGHT 62
#define PADDING 3
#define NUMBEROFBUTTONSINAROW 8
#define X 100
#define Y 100
#define TOTALBUTTONS 40

NSMutableArray *array = [[NSMutableArray alloc] init];

    for(int i=0 ; i<TOTALBUTTONS;i++)
    {
        UIButton *btnClick = [UIButton buttonWithType:UIButtonTypeCustom];
        [btnClick setImage:[UIImage imageNamed:@"ship.jpg"] forState:UIControlStateNormal];
        [btnClick setFrame:CGRectMake(X+((WIDTH + PADDING) * (i%NUMBEROFBUTTONSINAROW)), Y + (HEIGHT + PADDING)*(i/NUMBEROFBUTTONSINAROW), WIDTH, HEIGHT)];
        [btnClick addTarget:self action:@selector(btnTapped:) forControlEvents:UIControlEventTouchUpInside];
        btnClick.tag=i + 1;
        [self.view addSubview:btnClick];

        [array addObject:btnClick];
    }

and finally the button action :-

-(void)btnTapped:(id)sender
{

    NSLog(@"Button Clicked %d",((UIButton *)sender).tag);
}

you can access the button by tag value . The array is not required. WELL BUT if you like , access it by array.

Alternatively You can create a class associating all the button customizations with it and store the class object in Array , only to access it later on.In , this case the button implementation will be in the class.
