1Password是啥我在这里不再赘述，不了解的话可以去官网了解一下～
1Password可以方便的存储我们的账号密码，而且生成的账号密码非常复杂，安全性非常高。如果我们的app也支持1Password，那无疑会方便用户，而且提高我们app的“bigger”
1Password开发网站在GitHub上，里面介绍比较详细，我也是刚刚看完它的readme，然后过来卖弄。
1. 集成1Password需要三个文件
图片集、头文件、实现文件
集成三个文件
2.编辑URLScheme
因为需要跳转，在iOS9系统里，需要配置URLScheme，
在工程的plist文件中，添加LSApplicationQueriesSchemes数组，并且在数组内添加一个名为org-appextension-feature-password-management的成员就可以了
plist文件编辑
3.增加1Password按键
在xib中增加一个按键，图标在1Password.xcassets上有
这个按键在有1Password服务的时候显示，否则不显示
self.onePassBtn.hidden = ![[OnePasswordExtension sharedExtension] isAppExtensionAvailable];
4. 集成1Password需要实现三种功能
下面我们就可以集成1Password了，需要集成的地方有三个：注册账号时，登陆时，修改密码时
注册账号：（保存账号密码）
- (IBAction)saveLoginTo1Password:(id)sender {
NSDictionary *newLoginDetails = @{
AppExtensionTitleKey: @"XX客户端账号",
AppExtensionUsernameKey: self.nameLabel.text ? : @"",
AppExtensionPasswordKey: self.passLabel.text ? : @"",
AppExtensionNotesKey: @"在XX客户端中保存",
};
// The password generation options are optional, but are very handy in case you have strict rules about password lengths, symbols and digits.
NSDictionary *passwordGenerationOptions = @{
// The minimum password length can be 4 or more.
AppExtensionGeneratedPasswordMinLengthKey: @(6),
// The maximum password length can be 50 or less.
AppExtensionGeneratedPasswordMaxLengthKey: @(20),
// If YES, the 1Password will guarantee that the generated password will contain at least one digit (number between 0 and 9). Passing NO will not exclude digits from the generated password.
AppExtensionGeneratedPasswordRequireDigitsKey: @(YES),
// If YES, the 1Password will guarantee that the generated password will contain at least one symbol (See the list bellow). Passing NO with will exclude symbols from the generated password.
AppExtensionGeneratedPasswordRequireSymbolsKey: @(NO),
// Here are all the symbols available in the the 1Password Password Generator:
// !@#$%^&*()_-+=|[]{}'\\";.,>?/~`
// The string for AppExtensionGeneratedPasswordForbiddenCharactersKey should contain the symbols and characters that you wish 1Password to exclude from the generated password.
AppExtensionGeneratedPasswordForbiddenCharactersKey: @"!@#$%/lIO"
};
[[OnePasswordExtension sharedExtension] storeLoginForURLString:@"XX客户端" loginDetails:newLoginDetails passwordGenerationOptions:passwordGenerationOptions forViewController:self sender:sender completion:^(NSDictionary *loginDictionary, NSError *error) {
if (loginDictionary.count == 0) {
if (error.code != AppExtensionErrorCodeCancelledByUser) {
NSLog(@"Failed to use 1Password App Extension to save a new Login: %@", error);
}
return;
}
self.nameLabel.text = loginDictionary[AppExtensionUsernameKey] ? : @"";
self.passLabel.text = loginDictionary[AppExtensionPasswordKey] ? : @"";
// retrieve any additional fields that were passed in newLoginDetails dictionary
}];
}
原理很简单，首先传入用户名和密码，如果用户在使用1Password保存账号密码之前，已经输入好了账号密码，那么就会直接带进1Password中，如果没有输入则传入为空，无论是否为空，都可以在1Password内继续修改账号密码
之后是声明对密码的限制，比如最大最小长度，是否允许特殊字符，规避的字符等
执行下面这个方法以后，会调用block内容
- (void)storeLoginForURLString:(nonnull NSString *)URLString loginDetails:(nullable NSDictionary *)loginDetailsDictionary passwordGenerationOptions:(nullable NSDictionary *)passwordGenerationOptions forViewController:(nonnull UIViewController *)viewController sender:(nullable id)sender completion:(nullable void (^)(NSDictionary * __nullable loginDictionary, NSError * __nullable error))completion ;
第一个参数URLString是我们这个应用的标志符，一般是一个网址，但是我发现用随便一个字符串也可以。
调用完成以后，会弹到1Password
弹出1Password，点击后就可以进入1Password
用户编辑完账号密码，点击完成以后，block内会对账号密码的输入框重新赋值
登陆：（获取账号密码）
- (IBAction)findLoginFrom1Password:(id)sender {
[[OnePasswordExtension sharedExtension] findLoginForURLString:@"XX客户端" forViewController:self sender:sender completion:^(NSDictionary *loginDictionary, NSError *error) {
if (loginDictionary.count == 0) {
if (error.code != AppExtensionErrorCodeCancelledByUser) {
NSLog(@"Error invoking 1Password App Extension for find login: %@", error);
}
return;
}
self.nameLabel.text = loginDictionary[AppExtensionUsernameKey];
self.passLabel.text = loginDictionary[AppExtensionPasswordKey];
}];
}
读取是最简单的，只需要带入我们的URLString就可以了
修改密码：
- (IBAction)changePasswordIn1Password:(id)sender {
NSString *changedPassword = self.anewPassLabel.text ? : @"";
NSString *oldPassword = self.passLabel.text ? : @"";
NSDictionary *loginDetails = @{
AppExtensionTitleKey: @"XX客户端账号", // Optional, used for the third schenario only
AppExtensionPasswordKey: changedPassword,
AppExtensionOldPasswordKey: oldPassword,
AppExtensionNotesKey: @"在XX客户端中保存", // Optional, used for the third schenario only
};
// The password generation options are optional, but are very handy in case you have strict rules about password lengths, symbols and digits.
NSDictionary *passwordGenerationOptions = @{
// The minimum password length can be 4 or more.
AppExtensionGeneratedPasswordMinLengthKey: @(6),
// The maximum password length can be 50 or less.
AppExtensionGeneratedPasswordMaxLengthKey: @(20),
// If YES, the 1Password will guarantee that the generated password will contain at least one digit (number between 0 and 9). Passing NO will not exclude digits from the generated password.
AppExtensionGeneratedPasswordRequireDigitsKey: @(YES),
// If YES, the 1Password will guarantee that the generated password will contain at least one symbol (See the list bellow). Passing NO with will exclude symbols from the generated password.
AppExtensionGeneratedPasswordRequireSymbolsKey: @(NO),
// Here are all the symbols available in the the 1Password Password Generator:
// !@#$%^&*()_-+=|[]{}'\\";.,>?/~`
// The string for AppExtensionGeneratedPasswordForbiddenCharactersKey should contain the symbols and characters that you wish 1Password to exclude from the generated password.
AppExtensionGeneratedPasswordForbiddenCharactersKey: @"!@#$%/lIO"
};
[[OnePasswordExtension sharedExtension] changePasswordForLoginForURLString:@"XX客户端" loginDetails:loginDetails passwordGenerationOptions:passwordGenerationOptions forViewController:self sender:sender completion:^(NSDictionary *loginDictionary, NSError *error) {
if (loginDictionary.count == 0) {
if (error.code != AppExtensionErrorCodeCancelledByUser) {
NSLog(@"Error invoking 1Password App Extension for find login: %@", error);
}
return;
}
self.passLabel.text = loginDictionary[AppExtensionOldPasswordKey];
self.anewPassLabel.text = loginDictionary[AppExtensionPasswordKey];
}];
}
跟保存类似，首先传入老、新密码（但是貌似传老密码没什么卵用，老密码采使用的是进入1Password以后，选择的账号的密码）。
然后配置密码的限制，进入1Password，设置好了以后，在完成的block中修改老、新密码的内容，老的填上次存储的，新的填刚改的
至此，1Password就集成完了。
你可以在官方GitHub上运行Demo代码看看效果。
PS：
我之前没用过1Password，但是我发现了一个不太好的地方，注册的时候，如果已经有一个叫xiaoming的账号，密码是123456，我再注册一个xiaoming，密码是qwerty，保存以后，1Password里会有两个xiaoming账号，而且密码都变成了qwerty，不知道是不是Demo代码有问题。总之官方的Demo也是这样，一直没找到原因，求指导
