我有一个带有3个UIButton的NSMutableArray和带有50个UIButtons的第二个NSMutableArray。我想把这3个UIButtons标题按字符分配给SecondArray的每个UIButton.but这50个UIButtons of Second Array中的每一个都已经有单个Character.My Basics的目的是首先我要检查每个的长度。我的第一个数组的uibutton标题,然后通过索引将其分配给第二个数组中的UIButton。(对于Exp,如果我的第一个Button有标题“stack”,第二个“结束”和第三个“流”没有我想要分配索引的UIButtons在第二个数组中0-5,13-16,35-38)。我的第一个数组有3个UIBttons。有代码。

NSMutableArray *buttons = [NSMutableArray arrayWithObjects:btn1, btn2, btn3, nil];
            [btn1 setTitle:@"stack" forState:UIControlStateNormal]; 
            [btn2 setTitle:@"over" forState:UIControlStateNormal]; 
            [btn3 setTitle:@"flow" forState:UIControlStateNormal]; 

这是我的代码。要创建50个UIButtons。

 -(void)button:(id)sender {
  saveBtn = [[NSMutableArray alloc] init];
  arr=[[NSArray alloc]
  initWithObjects:@"A",@"B",@"C",@"D",@"E",@"F",@"G",@"H",@"I",@"J",@"K",@"L",
     @"M",@"N",@"O",@"P",@"Q",@"R",@"S",@"T",@"U",@"V",@"W",@"X",@"Y",@"Z",nil];

    for (int i=0; i<50; i++) {
            btn = [UIButton   buttonWithType:UIButtonTypeRoundedRect];
            btn.frame = CGRectMake(spacex, spacey, 30.0, 30.0);
            int idx;
            idx = arc4random()%[arr count];
            NSString* titre = [arr objectAtIndex:idx];
            [btn setTitle:titre forState:UIControlStateNormal];   
            spacex = spacex + 30;
            [saveBtn addObject:btn];
            [self.view addSubview:btn];

        }


            }

任何人指导我如何将我的UIButton标题分配给特定索引上的这些UIButton。感谢名单

Thanx帮助每个人..但我在这里完成的是代码。我可以帮助其他人。

 - (void)getbuttontitle {
   for(int i = 0;i<[buttons count];i++)
  {
     if(i == 0)
    {
     UIButton *b1 = [buttons objectAtIndex:0];
      a = (NSString *)[[b1 titleLabel] text];
        [storewords addObject:a];
        NSLog(@"b=%@",a);
        }
    else if(i == 1)
    {

    }
    else if(i == 2)
    { 

    }
 }
}

    for (NSString *str in storewords) {
        if (str==a) {
            int j = 0;
            int randn= (arc4random()%5)+1 ;
            NSLog(@"n=%d",randn);
            for (int i=randn; i<[a length]+randn; i++) {
                NSLog(@"a=%@",a);
                NSString *ichar  = [NSString stringWithFormat:@"%c", [a characterAtIndex:j]];
                UIButton*  b = [saveBtn objectAtIndex:i];
                NSLog(@"a=%@",ichar);
                j++;
                [b setTitle:ichar forState:UIControlStateNormal]; 
            }   
        }

        if (str==c) {


        }   

        if (str==d) {

        }       
    }
