##LYModelFilter
一个提取子数组的工具，可以任意匹配数据格式，并得到结果
###1、安装
pod 'LYModelFilter'
###2、使用 ####2.1、原始数据
Student *student1 = [[Student alloc] init];
student1.name = @"boy1";
student1.age = @18;
student1.score = 80;
student1.height = 180.1f;
student1.student_id = 11111111;
Student *student2 = [[Student alloc] init];
student2.name = @"boy2";
student2.age = @17;
student2.score = 80;
student2.height = 180.1f;
student2.student_id = 22222222;
Student *student3 = [[Student alloc] init];
student3.name = @"boy3";
student3.age = @16;
student3.score = 70;
student3.height = 180.1f;
student3.student_id = 33333333;
Student *student4 = [[Student alloc] init];
student4.name = @"boy4";
student4.age = @15;
student4.score = 60;
student4.height = 145.9f;
student4.student_id = 44444444;
Student *student5 = [[Student alloc] init];
student5.name = @"boy5";
student5.age = @14;
student5.score = 50;
student5.height = 160.5f;
student5.student_id = 55555555;
Student *student6 = [[Student alloc] init];
student6.name = @"boy6";
student6.age = @13;
student6.score = 40;
student6.height = 175.9f;
student6.student_id = 66666666;
Student *student7 = [[Student alloc] init];
student7.name = @"girl1";
student7.age = @12;
student7.score = 30;
student7.height = 164;
student7.student_id = 77777777;
####2.2、获取年龄大于等于14岁的学生
id value = [aSchool.students ly_makeRules:^(LYModelFilter *filter) {
filter.ONE().property(@"age").largeOrEqualTo(@14);
}];
NSLog(@"student (age >= 14) : %@", value);
####2.3、获取年龄大于等于14岁或者分数小于等于70分的学生
// age >= 14 || score <= 70
id value = [aSchool.students ly_makeRules:^(LYModelFilter *filter) {
filter.ONE().property(@"age").largeOrEqualTo(@14);
filter.OR_ONE().property(@"score").smallOrEqualTo(@70);
}];
NSLog(@"student (age >= 14 or score <= 70) : %@", value);
####2.4、获取年龄大于等于14岁且分数小于等于70分的学生
// age >= 14 && score <= 70
id value = [aSchool.students ly_makeRules:^(LYModelFilter *filter) {
filter.ONE().property(@"age").largeOrEqualTo(@14);
filter.AND_ONE().property(@"score").smallOrEqualTo(@70);
}];
NSLog(@"student (age >= 14 and score <= 70) : %@", value);
####2.5、获取学号最大的学生
// student_id max
id value = [aSchool.students ly_makeRules:^(LYModelFilter *filter) {
filter.ONE().max(@"student_id");
}];
NSLog(@"student (student_id max) : %@", value);
####2.6、获取学号最小的学生
// student_id min
id value = [aSchool.students ly_makeRules:^(LYModelFilter *filter) {
filter.ONE().min(@"student_id");
}];
NSLog(@"student (student_id min) : %@", value);
####2.7、获取学号最小且年龄小于15的学生
// student_id min and age <= 15
id value = [aSchool.students ly_makeRules:^(LYModelFilter *filter) {
filter.ONE().min(@"student_id");
filter.AND_ONE().property(@"age").smallOrEqualTo(@15);
}];
NSLog(@"student (student_id min and age <= 15) : %@", value);
####2.8、获取数组中NSString类型，且内容是new1的数据
NSMutableArray *temp1 = [NSMutableArray arrayWithArray:aSchool.students];
[temp1 addObject:@"new1"];
[temp1 addObject:@"new2"];
[temp1 addObject:@"new3"];
id value = [temp1 ly_makeRules:^(LYModelFilter *filter) {
filter.className(@"NSString");
filter.ONE().equalTo(@"new1");
}];
NSLog(@"value in temp1 : %@", value);
####2.9、自定义匹配规则(代码为找到名字中包含boy的数组)（version 1.0.1更新）
NSArray *boys = [aSchool.students ly_makeRules:^(LYModelFilter *filter) {
LYModelFilterItemCustomBlock block = ^BOOL(id left , id right) {
if ([left rangeOfString:right].location != NSNotFound) {
return YES;
}
return NO;
};
filter.ONE().property(@"name").custom(block, @"boy");
}];
NSLog(@"boys : %@", boys);
###3.0其他功能
支持property(@"a.b.c")的方式来找到嵌套的model的属性
