## ZLAppUpdate检测升级 ##
* 1.请求APPStore上当前版本信息
* 2.自定义更新模式：强制更新，非强制更新
* 3.显示最新版本的新功能描述
* 4.支持iOS macOS
@interface ZLAppUpdate : NSObject
/** 版本更新优先级 */
```
typedef NS_ENUM(NSInteger, iVersionUpdatePriority)
{
iVersionUpdatePriorityDefault = 0,
iVersionUpdatePriorityLow = 1, //忽略
iVersionUpdatePriorityMedium = 2, //回头再说
iVersionUpdatePriorityHigh = 3 //强制更新
};
```
```
+ (ZLAppUpdate *)sharedInstance;
```

/** 好的 */
@property (nonatomic, copy) NSString *okButtonLabel;
/** 忽略 */
@property (nonatomic, copy) NSString *ignoreButtonLabel;
/** 回头再说 */

/** 如果没有本地list展示APPStore更新信息 */
@property (nonatomic, assign) BOOL useAppStoreDetailsIfNoPlistEntryFound;
/** 是否检测更新 */

@property (nonatomic, copy) NSString *localVersionsPlistPath;
/** 忽略的版本号 */
@property (nonatomic, copy) NSString *ignoredVersion;
/** 最后检测的时间 */
@property (nonatomic, strong) NSDate *lastChecked;
/** 最后忽略的时间 */
@property (nonatomic, strong) NSDate *lastReminded;
/** 更新的APP的URL */
@property (nonatomic, strong) NSURL *updateURL;
/** 是否展示版本的详细信息 */
@property (nonatomic, assign) BOOL viewedVersionDetails;
/** 代理 */
@property (nonatomic, weak_delegate) id<ZLAppUpdateDelegate> delegate;
```
### 实现方法
```
/** 是否打开APPStore中APP页面 */
- (BOOL)openAppPageInAppStore;
/** 检测新版本 */
- (void)checkIfNewVersion;
/** 新版本的详细信息 */
- (NSString *)versionDetails;
/** 是否需要检测更新 */
- (BOOL)shouldCheckForNewVersion;
/** 更新新版本 */
- (void)checkForNewVersion;
```
提示语言切换
```
