iphone - UILabel 中心内容

Question

这是我的代码:

UILabel *myLabel;
myLabel = [[UILabel alloc] initWithFrame:CGRectMake(20, 0, 300, 480)];
myLabel.lineBreakMode = UILineBreakModeWordWrap;
myLabel.numberOfLines = 2; // 2 lines ; 0 - dynamical number of lines
myLabel.text = @"Please select at least one image category!";
myLabel.font = [UIFont fontWithName:@"Arial-BoldMT" size: 24.0];
myLabel.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height/2);
myLabel.backgroundColor = [UIColor clearColor];
[self.view addSubview:myLabel];
[myLabel release];

我想知道是否可以将换行的文本居中，因为它排在左侧:

Answer 1

myLabel.textAlignment=UITextAlignmentCenter;
