如何水平居中 UILabel 文本

Answer 1

你应该正确设置帧： CGRectMake （pos.x、 pos.y、 宽度、 高度）
self.aboutMee = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, self.view.bounds.size.height)];
self.aboutMee.text = @"About Me";
self.aboutMee.textAlignment = NSTextAlignmentCenter;
self.aboutMee.backgroundColor = [UIColor clearColor];
self.aboutMee.font = [UIFont fontWithName:@"Helvetica" size:14];
[self.aboutMee setTextColor:[UIColor colorWithRed:0.0/255.0 green:140.0/255.0 blue:199.0/255.0 alpha:1.0]];
[self.aboutMee setFont:[UIFont fontWithName:@"HelveticaNeueLTStd-ThCn" size:35]];
[self.scrollView addSubview:self.aboutMee];
