Question

我需要将我的观点的所有颜色添加到NSMuttableArray。尝试这样做，但只添加一种颜色的最后一个视图。我的数组名为colorArray。请帮帮我。

我认为它应该在一个循环中完成，但我不确切地知道它的原因在哪里以及如何描述它

这是我的ViewController

#import "ViewController.h"
#import "RandomView.h"
@interface ViewController ()

@end

@implementation ViewController

@synthesize kol;
@synthesize sdvig1;
@synthesize sdvig2;
@synthesize myTextField;
@synthesize randView;
@synthesize redButton, greenButton, blueButton;
@synthesize colorArray;


- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
       self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        kol=10;
    }
    return self;
}


-(void) viewWillAppear:(BOOL)animated
{
    myTextField.delegate = self;
    kol=[[myTextField text] intValue];
}


- (void)viewDidLoad
{
    [super viewDidLoad];

    myTextField = [[UITextField alloc] initWithFrame:CGRectMake(0, 20, self.view.frame.size.width/4, 30)];
    myTextField.backgroundColor=[UIColor yellowColor];
    [myTextField setKeyboardType:UIKeyboardTypeNumberPad];
    [self.view addSubview:myTextField];


    redButton = [[UIButton alloc] initWithFrame:CGRectMake(self.view.frame.size.width/4, 20, self.view.frame.size.width/4, 30)];
    redButton.backgroundColor=[UIColor redColor];
    [redButton addTarget: self
              action: @selector(redSort:)    forControlEvents: UIControlEventTouchUpInside];


    greenButton = [[UIButton alloc] initWithFrame:CGRectMake(self.view.frame.size.width/4*2, 20, self.view.frame.size.width/4, 30)];
    greenButton.backgroundColor=[UIColor greenColor];
    [greenButton addTarget: self
                  action: @selector(greenSort:)    forControlEvents: UIControlEventTouchUpInside];


    blueButton = [[UIButton alloc] initWithFrame:CGRectMake(self.view.frame.size.width/4*3, 20, self.view.frame.size.width/4, 30)];
    blueButton.backgroundColor=[UIColor blueColor];
    [blueButton addTarget: self
                  action: @selector(blueSort:)    forControlEvents: UIControlEventTouchUpInside];

    [self.view addSubview:redButton];
    [self.view addSubview:greenButton];
    [self.view addSubview:blueButton];

    [self createView];

每次调用createView时，都会创建一个新数组。尝试将colorArray = [[NSMutableArray alloc] init];行移动到viewDidLoad方法中。
