【iOS】Object-C 检测属性修饰符是否使用正确

通过以下脚本，可以部分检测出代码中的属性修饰符是否使用正确，目前的检测只加了5道，可继续扩展。

## 检查带*号的指针变量是否使用了assign
def check1(name,type,modifier):
    if "*" in name and "assign" in modifier:
        return False
    return True
## 检查block是否使用过assign
def check2(name,type,modifier):
    if type == "Block" and "assign" in modifier:
        return False
    return True
## 检查代理是否使用过assign或strong或copy
def check3(name,type,modifier):
    if type.startswith("id<") and ("assign" in modifier):
        return False
    return True
### 检查是否用了retain
def check4(name,type,modifier):
    if "retain" in modifier:
        return False
    return True

## 检查可变数组可变字符串等是否正确使用了修饰符
def check5(name,type,modifier):
    if (type.startswith("NSMutable") or type.startswith("LHSafeMutable")) and ("copy" in modifier or "assign" in modifier):
        return False
    return True
