1.解决工程中输出无关日志
Edit Scheme -> Run -> Arguments, 在Environment Variables里边添加 OS_ACTIVITY_MODE disable
还会出现下面这个问题5]: Class PLBuildVersion is implemented in both /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/AssetsLibraryServices.framework/AssetsLibraryServices (0x112b58910) and /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator.sdk/System/Library/PrivateFrameworks/PhotoLibraryServices.framework/PhotoLibraryServices (0x112982210). One of the two will be used. Which one is undefined.
2.注释快捷键⌘+/失效
重启电脑,如果还不能使用的话就启用命令工具(命令运行 sudo /usr/libexec/xpccachectl),然后重启电脑
3.对于插件无法使用
网上推荐的是将Xcode拷贝一份可以使用插件的Xcode(在应用程序中),但是这个Xcode不能打包上传等,建议不要使用这种方法
三方插件解决方法(fix method):让你的Xcode8继续使用插件
4.iOS10隐私权限问题
iOS10中调用相机相册等系统功能时,需要在info.plist文件中添加字段,否则会出现闪退的情况
- <!-- 相册 -->
- <key>NSPhotoLibraryUsageDescription</key>
- <string>App需要您的同意,才能访问相册</string>
- <!-- 相机 -->
- <key>NSCameraUsageDescription</key>
- <string>App需要您的同意,才能访问相机</string>
- <!-- 麦克风 -->
- <key>NSMicrophoneUsageDescription</key>
- <string>App需要您的同意,才能访问麦克风</string>
- <!-- 位置 -->
- <key>NSLocationUsageDescription</key>
- <string>App需要您的同意,才能访问位置</string>

- <string>App需要您的同意,才能访问蓝牙</string>
- <!-- 媒体资料库 -->
- <key>NSAppleMusicUsageDescription</key>
- <string>App需要您的同意,才能访问媒体资料库</string>
5.label中的文字显示不全
Xcode8与Xcode7.3的文字宽度变化(英文字母没有问题,只有汉字有问题)
6.Notification(通知)
(1)所有相关通知被统一到了UserNotifications.framework框架中
(2)增加了撤销、更新、中途还可以修改通知的内容
(3)通知不再是简单的文本,现在还可以是图片、视频,自定义通知的展示等等
(4)iOS10相对之前的通知来说更好用更易于管理,并且进行了大规模优化
(5)iOS10之后,本地与远程通知集成在一个方法中
7.ATS问题
iOS10从2017年1月1日起只能使用HTTPS,否则提交App可能会被拒绝。
8.iOS10中UICollectionView性能优化
9.iOS10 UIColor新增方法
iOS10苹果建议我们使用sRGB,因为它性能更好,色彩更丰富。
- + (UIColor *)colorWithDisplayP3Red:(CGFloat)displayP3Red green:(CGFloat)green blue:(CGFloat)blue alpha:(CGFloat)alpha NS_AVAILABLE_IOS(10_0);
- - (UIColor *)initWithDisplayP3Red:(CGFloat)displayP3Red green:(CGFloat)green blue:(CGFloat)blue alpha:(CGFloat)alpha NS_AVAILABLE_IOS(10_0);
10.iOS10 UIScrollView新增refreshControl
也就是说以后只要是继承UIScrollView就支持刷新功能
- @property (nonatomic, strong, nullable) UIRefreshControl *refreshControl NS_AVAILABLE_IOS(10_0) __TVOS_PROHIBITED;
- - (void)viewDidLoad {
- [super viewDidLoad];
- UIScrollView *scrollView = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.bounds.size.width, 500)];
- scrollView.backgroundColor = [UIColor redColor];
- scrollView.contentSize = CGSizeMake(self.view.bounds.size.width, 1000);
- [self.view addSubview:scrollView];
- UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"1"]];
- [scrollView addSubview:imageView];
- // 添加下拉刷新控件
- UIRefreshControl *ref = [[UIRefreshControl alloc] init];
- // 监听刷新方法
- [ref addTarget:self action:@selector(refresh:) forControlEvents:UIControlEventValueChanged];
- scrollView.refreshControl = ref;
- self.view.backgroundColor = [UIColor redColor];
- }
- - (void)refresh:(UIRefreshControl *)ref {
- dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(22 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
- // 结束刷新
- [ref endRefreshing];
- });
- }
11.iOS10判断系统版本
- NSLog(@"%zd %f %@",
- [[[[UIDevice currentDevice] systemVersion] substringToIndex:1] integerValue],
- [[UIDevice currentDevice] systemVersion].floatValue,
- [[UIDevice currentDevice] systemVersion]);
12.UIStatusBar的问题
在iOS10中,如果还是用以前设置UIStatusBar类型或者控制隐藏还是显示的方法,会报警告,方法过期,如下图:
要想修改UIStatusBar的样式或者状态使用下图中所示的属性或方法:
- @property(nonatomic, readonly) UIStatusBarStyle preferredStatusBarStyle NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED; // Defaults to UIStatusBarStyleDefault
- @property(nonatomic, readonly) BOOL prefersStatusBarHidden NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED; // Defaults to NO
- - (UIStatusBarStyle)preferredStatusBarStyle NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED; // Defaults to UIStatusBarStyleDefault
- - (BOOL)prefersStatusBarHidden NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED; // Defaults to NO
- // Override to return the type of animation that should be used for status bar changes for this view controller. This currently only affects changes to prefersStatusBarHidden.
- - (UIStatusBarAnimation)preferredStatusBarUpdateAnimation NS_AVAILABLE_IOS(7_0) __TVOS_PROHIBITED; // Defaults to UIStatusBarAnimationFade
13.UITextField新增字段
在iOS10中,UITextField新增了textContentType字段,是UITextContentType类型,它是一个枚举,作用是可以指定输入框的类型,以便系统可以分析出用户的语义,是电话类型就建议一些电话,是地址类型就建议一些地址。可以在#import<UIkit/UITextInputTraits.h>文件中,查看textContentType字段,有以下可以选择的类型:
- UIKIT_EXTERN UITextContentType const UITextContentTypeName NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeNamePrefix NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeGivenName NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeMiddleName NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeFamilyName NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeNameSuffix NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeNickname NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeJobTitle NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeOrganizationName NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeLocation NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeFullStreetAddress NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeStreetAddressLine1 NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeStreetAddressLine2 NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeAddressCity NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeAddressState NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeAddressCityAndState NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeSublocality NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeCountryName NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypePostalCode NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeTelephoneNumber NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeEmailAddress NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeURL NS_AVAILABLE_IOS(10_0);
- UIKIT_EXTERN UITextContentType const UITextContentTypeCreditCardNumber NS_AVAILABLE_IOS(10_0);
14.推送
所有的推送平台,不管是极光还是什么的,要想收到推送,这个必须打开
15.蓝牙相关
CBCentralManagerState废弃,使用CBManagerState替代
CBCentralManager直接继承于CBManager,里面直接声明的属性:
@property(nonatomic, assign, readonly) CBManagerState state;
16.openURL的方法被遗弃,使用其替换方法
openURL:options:completionHandler:
17.iOS10字体随着手机系统字体而改变
iOS 10提供了这样的属性adjustsFontForContentSizeCategory来设置
- UILabel *myLabel = [UILabel new];
- // UIFont 的preferredFontForTextStyle:意思是指定一个样式,并让字体大小符合用户设定的字体大小
- myLabel.font = [UIFont preferredFontForTextStyle:UIFontTextStyleHeadline];
- myLabel.adjustsFontForContentSizeCategory = YES; // 是否更新字体的变化
