不抖动

1.设置字体样式 Courier 和字体大小
[label setFont:[UIFont fontWithName:@"Courier" size:font]];

2. 设置居中样式 NSTextAlignmentLeft
   self.labelTime = [UILabel labelWithTitle:@"00:00:00" titleFont:17 backgroundColor:RGB(50, 56, 65) textAlignment:NSTextAlignmentLeft ract:CGRectMake(x, y, w, h) numberOfLines:1];

3. 设置约束 centerY
   [self.labelTime mas_makeConstraints:^(MASConstraintMaker *make) {
   make.left.equalTo(self.mas_left).with.offset(10);
   make.centerY.equalTo(self);
   }];

抖动
// [label setFont:[UIFont systemFontOfSize:font]];
