使用@property ivars的最佳做法 [英] Best practice on using @property ivars

问题描述

有人可以分享一些有关在init方法或指定的初始化方法中使用@property iVars的最佳实践/代码约定的知识吗?

Could someone share some knowledge on whats best practice / code convention on using @property iVars in init methods or designated initializers?

请参见我的示例:

@interface MyClass ()
@property(nonatomic,strong) nsstring *tempString;
@property(nonatomic,strong) NSMutableArray *arrItems;
@end

@implementation ViewController

- (id)init
{
    if (self = [super init]) {

        //Is this best practice / correct
        _tempString = @"";
        _arrItems = [[NSMutableArray alloc] initWithCapacity:0];
        ...
        ...

        //Or this
        self.tempString = @"";
        self.arrItems = [[NSMutableArray alloc] initWithCapacity:0];
    }
    return self;
}

@end

关于为何应使用其中一个的任何建议?

Any advice on why one or the other should be used?

谢谢...
