目前为止,iPhone屏幕尺寸已经有四种:

3.5(inch):1/3G/3GS/4/4S

4.0(inch):5/5S/5C

4.7(inch):6

5.5(inch):6Plus

看一下iPhone4~6(+)的屏幕高宽比:

iPhone4(s):分辨率960*640,高宽比1.5 
iPhone5(s):分辨率1136*640,高宽比1.775 
iPhone6:分辨率1334*750,高宽比1.779 
iPhone6+:分辨率1920*1080,高宽比1.778

可粗略认为iPhone5(s)、6(+)的高宽比是一致的(16:9),即可以等比例缩放。因此可以按宽度适配: 
fitScreenWidth= width*(SCREEN_WIDTH/320) 
这样,共有iPhone3/4/5、6、6+三组宽度,在iPhone6、6+下将按比例横向放大,也就是说我们要适配宽、高、字号大小(如果说Android屏幕适配是地狱一般,那目前来看iPhone屏幕适配还是很美好的)

适配思路

现在产品设计稿有以iPhone5为基准的,也有以iPhone6为基准的,其实没太大影响,因为iPhone5、6、6P的屏幕尺寸比例几乎一样的,所以以iPhone5为基准标注的尺寸,那适配的方法如下:

#define kScreenWidthRatio  (kScreenWidth / 320.0)#define kScreenHeightRatio (kScreenHeight / 568.0)#define AdaptedWidthValue(x)  (ceilf((x) * kScreenWidthRatio))#define AdaptedHeightValue(x) (ceilf((x) * kScreenHeightRatio))
  • 1
  • 2
  • 3
  • 4

其实就是计算一个比例,然后iPhone6、6P等比放大,这样就保持了iPhone5、6、6P屏幕视觉效果上的一致了。 
控件尺寸思路搞定了,但仅仅控件等比例拉伸,其中的内容也要去适应,例如UILabel的字体大小适应,其实也很简单:

#define kUHSystemFontWithSize(R)     [UIFont fontWithName: kULSystemFont size: (AdaptedWidthValue(R))]

实践 
有了思路之后,实践一下看看效果,首先看一下最终目标效果图:

iOS开发~iPhone6及iPhone6P的UI适配

Demo简介:

1、利用TableView展示数据,其中TableView的headerView是滚动的广告,整体UI布局使用相对布局(Autolayout);

2、Autolayout用的是代码实现方式,借助与第三方库Masonry;

3、headerView的滚动广告实现是借助于第三方库SDCycleScrollView;

4、图片下载借助与第三方库SDWebImage;

5、UITableViewCell的自适应高度借助与第三方库UITableView+FDTemplateLayoutCell实现。

新建项目

使用Xcode新建项目后,由于使用到很多第三方,所以使用CocoPods,其中修改Podfile:

platform :ios, ‘7.0’ 
pod ‘Masonry’ 
pod ‘SDCycleScrollView’ 
pod ‘UITableView+FDTemplateLayoutCell’ 
pod ‘SDWebImage’

实现TableView 
1、创建TableView,命名为newslistView:

@property (nonatomic, strong) UITableView *newslistView;

具体实现不说了,介绍一下TableView的布局,这里TableView沾满ViewController的View: 
[self.newslistView mas_makeConstraints:^(MASConstraintMaker *make) { 
make.edges.equalTo(self.view); 
}];

2、实现TableViewHeader 
- (void) loadTableViewHeaderView { 
SDCycleScrollView * cycleScrollView = [SDCycleScrollView cycleScrollViewWithFrame:CGRectMake(0, 0, kScreenWidth, AdaptedHeightValue(SDCycleScrollViewHeight)) imageURLStringsGroup:nil]; // 模拟网络延时情景 
cycleScrollView.pageControlAliment = SDCycleScrollViewPageContolAlimentRight; 
cycleScrollView.delegate = self; 
cycleScrollView.showPageControl = YES; 
cycleScrollView.pageControlStyle = SDCycleScrollViewPageContolStyleAnimated; 
cycleScrollView.pageControlAliment = SDCycleScrollViewPageContolAlimentCenter; 
cycleScrollView.dotColor = [UIColor whiteColor]; // 自定义分页控件小圆标颜色 
cycleScrollView.placeholderImage = [UIImage imageNamed:@”detail_top”]; 
[self.view addSubview:cycleScrollView];

cycleScrollView.imageURLStringsGroup = [self.dataDictionary valueForKey:@"advertisement"];self.newslistView.tableHeaderView = cycleScrollView;

}

这里使用到了 AdaptedHeightValue(SDCycleScrollViewHeight)来适应屏幕尺寸,4/4S设备的TableViewHeader高度就小一些,6和6P的TableViewHeader高度就大一些,因为我们是已5代设备为参考实现的产品设计稿。 
3、实现TableViewCell

   }];    [self.titleLabel mas_makeConstraints:^(MASConstraintMaker *make) {        make.top.equalTo(self.contentView.mas_top).offset(AdaptedHeightValue(ULNewsListCellTitleLabelMarginTop));        make.left.equalTo(self.newsImageView.mas_right).offset(AdaptedWidthValue(ULNewsListCellTitleLabelMarginLeft));

       make.bottom.equalTo(self.lineView.mas_bottom).offset(-AdaptedHeightValue(ULNewsListCellContentLabelMarginBottom));    }];    [self.lineView mas_makeConstraints:^(MASConstraintMaker *make) {        make.bottom.equalTo(self.contentView.mas_bottom).offset(-ULNewsListCellLineViewHeight);
