Answer 1

我在你的代码中添加了两行并修改了一行，希望它对你有帮助..

UIImageView *newView =[[UIImageView alloc]initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 150.0f)];
[newView setImage:[UIImage imageNamed:@"3.png"]];//Modified line
[self.view addSubview:newView];//New added line

UILabel *newLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 150.0f, 150.0f)];
newLabel.translatesAutoresizingMaskIntoConstraints = NO;
newLabel.textAlignment = NSTextAlignmentCenter;
newLabel.lineBreakMode = NSLineBreakByClipping;
newLabel.adjustsFontSizeToFitWidth = YES;
newLabel.text = @"labelText";
newLabel.backgroundColor = [UIColor clearColor];
[newView addSubview:newLabel];

如果你的newLabel文字很长，你可以添加它..

newLabel.numberOfLines = 3;//New added line
