選択したときにカスタムボタンがテキストの色を変更しない

Question

forループを使用して3つのカスタムボタンを作成しました。しかし、ボタンを選択すると、テキストの色は変化しません。私はどのようにしますか？私は何を追加しなければならない？ここで

は、通常の状態のため

buttonText = [[NSArray alloc]initWithObjects: @"Slambook",@"Initiated",@"Collaborated",nil];  
NSInteger numControllers = [viewControllerArray count]; 

for (int i = 0; i<numControllers; i++) { 

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
    button.frame = CGRectMake(X_BUFFER+i*(self.view.frame.size.width-2*X_BUFFER)/numControllers-X_OFFSET, Y_BUFFER, (self.view.frame.size.width-2*X_BUFFER)/numControllers, HEIGHT); 
    [button setTitleColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateHighlighted]; 
    [button setTitleColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateSelected]; 
    [button setTitle:[buttonText objectAtIndex:i] forState:UIControlStateNormal]; 
    [button addTarget:self action:@selector(tapButtonAction:) forControlEvents:UIControlEventTouchUpInside]; 
    [navigationView addSubview:button]; 
}

私はダミーテキストを持つ単一のボタンのコードを試してみましたが、あなたの変更、黒のテキストの色、私のコードですタップするとボタンの色がハイライト表示されます：

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
    button.frame = CGRectMake(20, 40,50 , 35); 
//  button.frame = CGRectMake(X_BUFFER+i*(self.view.frame.size.width-2*X_BUFFER)/numControllers-X_OFFSET, Y_BUFFER, (self.view.frame.size.width-2*X_BUFFER)/numControllers, HEIGHT); 
    [button setTitle:@"Dummy" forState:UIControlStateNormal]; 
    [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal]; 
     [button setTitleColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateHighlighted]; 

     [button addTarget:self action:@selector(tapButtonAction:) forControlEvents:UIControlEventTouchUpInside]; 
     [self.view addSubview:button]; 

ボタンの色を長時間変えないで、ボタンのテキストの色を変更します。

[ボタン色： 255.0アルファ：1] forState：UIControlStateHighlighted];あなたはボタンのクリックでテキストの色を変更したい

NSInteger numControllers = [viewControllerArray count]; 

    for (int i = 0; i<numControllers; i++) { 

     UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
     button.frame = CGRectMake(X_BUFFER+i*(self.view.frame.size.width-2*X_BUFFER)/numControllers-X_OFFSET, Y_BUFFER,(self.view.frame.size.width-2*X_BUFFER)/numControllers, HEIGHT); 
    button.tag=i+200; 
     [button setTitleColor:[UIColor blackcolor] forState:UIControlStateNormal]; 
     [button setBackgroundColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1]]; 
     [button addTarget:self action:@selector(tapButtonAction:) forControlEvents:UIControlEventTouchUpInside]; 
     [navigationView addSubview:button]; 
    } 
- (IBAction)tapButtonAction:(id)sender 
{ 

    UIButton *btn = (UIButton*)sender; 

     [btn setBackgroundColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateNormal]; 
     [btn setTitleColor:[UIColor blackcolor] forState:UIControlStateNormal]; 

    for (int i = 0; i<numControllers; i++) { 
     UIButton *restBtn=[navigationView viewWithTag:i+200]; 
    if(restbtn!= btn) 
    { 
     [restBtn setBackgroundColor:[UIColor grayColor] forState: UIControlStateNormal]; 
     [restBtn setTitleColor:[UIColor blackcolor] forState:UIControlStateNormal]; 
} 

    } 
}

NSInteger numControllers = [viewControllerArray count]; 

    for (int i = 0; i<numControllers; i++) { 

     UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom]; 
     button.frame = CGRectMake(X_BUFFER+i*(self.view.frame.size.width-2*X_BUFFER)/numControllers-X_OFFSET, Y_BUFFER, (self.view.frame.size.width-2*X_BUFFER)/numControllers, HEIGHT); 
     [button setTitleColor:[UIColor blackcolor] forState:UIControlStateNormal]; 
     [button setBackgroundColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1]]; 
     [button addTarget:self action:@selector(tapButtonAction:) forControlEvents:UIControlEventTouchUpInside]; 
     [navigationView addSubview:button]; 
    } 
- (IBAction)tapButtonAction:(id)sender 
{ 

    UIButton *btn = (UIButton*)sender; 
    if ([btn isSelected]) { 
     [btn setSelected:NO]; 
     [btn setBackgroundColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateNormal]; 
     [btn setTitleColor:[UIColor blackcolor] forState:UIControlStateNormal]; 

    } 
    else 
    { 
     [btn setSelected:YES]; 
     [btn setBackgroundColor:[UIColor colorWithRed:204.0/255.0 green:24.0/255.0 blue:204.0/255.0 alpha:1] forState:UIControlStateNormal]; 
     [btn setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal]; 

    } 
} 

このコードのforループ

int x = 0; 
    for (int i = 0; i < [viewControllerArray count]; i++){ 
     //int y=2; 
     UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(x+2, 0, 40, 36)]; 

     id myArrayElement=[viewControllerArray objectAtIndex:i]; 

     [button setTitle:[NSString stringWithFormat:@"%@",myArrayElement] forState:UIControlStateNormal]; 
     [button setTitleColor:[UIColor blackcolor]]; 

     button.titleLabel.font = [UIFont systemFontOfSize:15]; 


     x += button.frame.size.width; 

     [button setBackgroundColor:[UIColor colorWithRed:137.0/255.0 green:110.0/255.0 blue:255.0/255.0 alpha:1] forState:UIControlStateNormal]; 
     [button addTarget:self action:@selector(tapButtonAction:) forControlEvents:UIControlEventTouchUpInside]; 
    }
