iphone - 无法设置 UIButton 的标题

Question

我是 iPhone 新手，

    xpos=30;
    ypos=40;

for(int i=0;i<[MyArray count];i++)
        {            
            if(i!=0)
            {
                if (i%4==0) 
                {                    
                    ypos+=180;
                    xpos=30;
                }
                else
                {
                    xpos+=200;
                }
            }
            
            button = [UIButton buttonWithType:UIButtonTypeCustom];
            button.frame = CGRectMake(xpos, ypos, 110.0, 130.0);
            [button setImage: [UIImage imageNamed:@"ibook2.png"] forState:UIControlStateNormal];
            [button setTitleEdgeInsets:UIEdgeInsetsMake(ypos, xpos, 0.0, 0.0)];
            [button setTitle:[NSString stringWithFormat:@"%@", [MyArray objectAtIndex:i]] forState:UIControlStateNormal];
            [button setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
            [self.view addSubview:button];
}

我可以看到按钮，但无法在 UIButton 上看到我的文字。

我们将不胜感激。

请设置按钮背景图像。您已设置按钮图像。请使用这个:

[button setBackgroundImage:[UIImage imageNamed:@"blue_button.png"]
                            forState:UIControlStateNormal];

对于包装按钮标题用户:

[button setTitle:@"Test button name 123" forState:UIControlStateNormal];

 button.titleLabel.numberOfLines=2;

 button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
