无法设置UIButton的标题

Question

I am new to iPhone,

    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];
}

i am able to see button but unable to see my text on the UIButton.

Any help will be appreciated.

Answer 1

Please set buttons background image.You have set buttons image. Please use this:

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

For Wrapping button title User:

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

 button.titleLabel.numberOfLines=2;

 button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;

Answer 2

You can't see the text because you have used setImage: function of button. At a time you can display image or button on text but you can add image as a background so you can see both image and tittle. In short set image as a background.

[btn setBackgroundImage:[UIImage imageNamed:@"imageName"] forState:UIControlStateNormal];

Please also remove the line of setting inset.

Answer 3

Rather then setting

[button setImage: [UIImage imageNamed:@"ibook2.png"] forState:UIControlStateNormal];   // This will not allow you to set Button title.

You have to use :

[button setBackgroundImage: [UIImage imageNamed:@"ibook2.png"] forState:UIControlStateNormal];    // This will allow you to set title along background button image.

Answer 4

如果图像太大，则仅会显示图像，并且文本会由于图像而被截断，因为文本在图像后将可见，请尝试使用setBackground图像或尝试使用小分辨率图像或setImageEdgeInsets。
