验证值是否合法 Validate the value
+objectIsNilOrNull:
对象判空。(Validate the object is nil or null.)
NSObject *object; // Nil
LOG_FORMAT(@"1: %d", [EFUtils objectIsNilOrNull:object]);
object = [NSNull null]; // Null
LOG_FORMAT(@"2: %d", [EFUtils objectIsNilOrNull:object]);
object = [NSObject alloc]; // Object alloc
LOG_FORMAT(@"3: %d", [EFUtils objectIsNilOrNull:object]);
if (![EFUtils objectIsNilOrNull:object]) { // 不为空
// do some thing here
}
+stringIsNilOrNullOrEmpty:
字符串判空。(Validate the string is nil or null or empty.)
NSString *string; // Nil
LOG_FORMAT(@"1: %d", [EFUtils stringIsNilOrNullOrEmpty:string]);
string = (NSString *)[NSNull null]; // Null
LOG_FORMAT(@"2: %d", [EFUtils stringIsNilOrNullOrEmpty:string]);
string = @""; // String with a empty string
LOG_FORMAT(@"3: %d", [EFUtils stringIsNilOrNullOrEmpty:string]);
if (![EFUtils stringIsNilOrNullOrEmpty:string]) { // 不为空
// do some thing here
}
+validateString:byRegExp:
使用正则表达式验证字符串值。(Validate the string by a regular expression.)
// AppUtils
/**
检查用户名是否合法
@param userName 用户名，是一个手机号码
@return 检查结果，YES 合法 NO 不合法
*/
+ (BOOL)checkUserName:(NSString *_Nonnull)userName {
return [EFUtils validateString:userName byRegExp:@"^1\\d{10}$"];
}
// Test
LOG_FORMAT(@"1: %d", [AppUtils checkUserName:@"123456"]);
LOG_FORMAT(@"2: %d", [AppUtils checkUserName:@"01234567890"]);
LOG_FORMAT(@"3: %d", [AppUtils checkUserName:@"13678234511"]);
if (![AppUtils checkUserName:userName]) { // 不合法
LOG_FORMAT(@"用户名是一个手机号码，请检查");
return;
}
+objectValueIsNilOrNull:withKey:
字典中指定键值判空。(Validate the key value in a dictionary is nil or null.)
NSDictionary *dictionary = @{@"ID": @59,
@"name": @"James",
@"age": [NSNull null],
@"offline": @true};
LOG_FORMAT(@"1: %d", [EFUtils objectValueIsNilOrNull:dictionary withKey:@"name"]);
LOG_FORMAT(@"2: %d", [EFUtils objectValueIsNilOrNull:dictionary withKey:@"age"]);
LOG_FORMAT(@"3: %d", [EFUtils objectValueIsNilOrNull:dictionary withKey:@"nick"]);
if (![EFUtils objectValueIsNilOrNull:dictionary withKey:@"nick"]) { // 不为空
// do some thing here
}
+objectValueIsEqualTo:dictionary:withKey:
字典中指定键值是否等于指定数值。(Validate the key value in a dictionary is equal to another integer value in a NSNumber or NSString object or not.)
NSDictionary *dictionary = @{@"status": @200,
@"ID": @59,
@"name": @"James",
@"age": [NSNull null],
@"offline": @true};
LOG_FORMAT(@"1: %d", [EFUtils objectValueIsEqualTo:@"00000059" dictionary:dictionary withKey:@"ID"]);
LOG_FORMAT(@"2: %d", [EFUtils objectValueIsEqualTo:@YES dictionary:dictionary withKey:@"offline"]);
LOG_FORMAT(@"3: %d", [EFUtils objectValueIsEqualTo:@1 dictionary:dictionary withKey:@"offline"]);
if ([EFUtils objectValueIsEqualTo:@200 dictionary:dictionary withKey:@"status"]) { // 请求成功
// do some thing here
}
+validateDictionary:
字典中所有的值都不为空，注意之前 +validDictionary: 返回的值已发生反转。(Validate all values in a dictionary is all not empty, note that the returned value from +validDictionary: has been reversed.)
NSDictionary *dictionary = @{@"ID": @59,
@"name": @"James",
@"age": [NSNull null],
@"offline": @true};
LOG_FORMAT(@"%d", [EFUtils validateDictionary:dictionary]);
if ([EFUtils validateDictionary:dictionary]) { // 返回数据均不为空
// do some thing here
