iOS 常用代码块

刚在网上看到一篇关于 CodeSnippets 的文章，发现自己好像一直也是这样做的，但是从来没整理过的，So 利用空余时间整下的。

一、直接创建

Create Code Snippet 确认

通常创建后，可以直接使用快捷键

快捷键直接使用

二、或是到相应目录下粘贴之前保存的

CodeSnippets

~/Library/Developer/Xcode/UserData/CodeSnippets

没有CodeSnippets 的时候，直接复制 CodeSnippets 就好了。

三、常用 代码块记录

• 3-1、初始化

my_init_vc

#pragma mark - Life Cycle
- (void)viewDidLoad {
    [super viewDidLoad];
    [self setupUI];
}

#pragma mark - Method

#pragma mark - Delegate

#pragma mark - SetupUI
- (void)setupUI {
    
    [self addViewConstraints];
}

}

#pragma mark - Getter

my_init_view

#pragma mark - Life Cycle
- (instancetype)initWithFrame:(CGRect)frame {
    if (self = [super initWithFrame:frame]) {
        [self setupUI];
    }
    return self;
}

#pragma mark - Method

}

my_init_cell

#pragma mark - Life Cycle
- (instancetype)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier {
    if (self = [super initWithStyle:style reuseIdentifier:reuseIdentifier]) {
        [self setupUI];
    }
    return  self;
}

- (void)awakeFromNib {
    [super awakeFromNib];
    // Initialization code
}

    if (!_<#UIView view#>) {
        _<#UIView view#> = [[UIView alloc] init];

    }
    return _<#UIView view#>;

    if (!_<#UIButton#>) {
        _<#UIButton#> = [UIButton buttonWithType:UIButtonTypeCustom];
        [_<#UIButton#> addTarget:self action:@selector(<#UIButton#>Action) forControlEvents:UIControlEventTouchUpInside];
    }
    return _<#UIButton#>;
}

- (UILabel *)<#UILabel#> {
    if (!_<#UILabel#>) {
        _<#UILabel#> = [[UILabel alloc] init];
        _<#UILabel#>.textColor = <#UIColor#>;
        _<#UILabel#>.font = <#UIFont#>;
    }
    return _<#UILabel#>;
}

• 3-3、属性

my_pro_assigin

@property (nonatomic, assign) <#type#> <#name#>;

my_pro_copy

@property (nonatomic, copy) <#type#> *<#name#>;

my_pro_strong

@property (nonatomic, strong) <#type#> *<#name#>;

my_pro_weak

@property (nonatomic, weak) <#type#> <#name#>;

• 3-4、常用 View
  my_tableView

<UITableViewDelegate, UITableViewDataSource>

// 将其移动到interface中
@property (nonatomic, strong) UITableView *tableView;

#pragma mark - UITableViewDataSource
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    return <#NSInteger number#>;
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    <#UITableViewCell cell#> *cell = [tableView dequeueReusableCellWithIdentifier:NSStringFromClass(<#UITableViewCell cell#>.self) forIndexPath:indexPath];
    return cell;
}

#pragma mark - UITableViewDelegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

}

- (UITableView *)tableView {
    if (!_tableView) {
        _tableView = [[UITableView alloc] initWithFrame:CGRectZero style:UITableViewStylePlain];
        _tableView.delegate = self;
        _tableView.dataSource = self;
        _tableView.estimatedRowHeight = 60;
        _tableView.estimatedSectionFooterHeight = 40;
        _tableView.estimatedSectionHeaderHeight = 0;
        _tableView.separatorStyle = UITableViewCellSelectionStyleNone;
        _tableView.backgroundColor = [UIColor whiteColor];
        [_tableView registerClass:[<#UITableViewCell cell#> class] forCellReuseIdentifier:NSStringFromClass(<#UITableViewCell cell#>.self)];
    }
    return _tableView;
}

my_collectionView

<UICollectionViewDelegate, UICollectionViewDataSource, UICollectionViewDelegateFlowLayout>

@property (nonatomic, strong) UICollectionView *collectionView;

#pragma mark - UICollectionViewDataSource
- (NSInteger)collectionView:(UICollectionView *)collectionView numberOfItemsInSection:(NSInteger)section {
    return <#numbers#>;
}

- (UICollectionViewCell *)collectionView:(UICollectionView *)collectionView cellForItemAtIndexPath:(NSIndexPath *)indexPath {
    <#collectionViewcell#> *cell = [collectionView dequeueReusableCellWithReuseIdentifier:NSStringFromClass(<#collectionViewcell#>.class) forIndexPath:indexPath];
    return cell;
}

#pragma mark - UICollectionViewDelegateFlowLayout
- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath {
    return CGSizeZero;
}

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout insetForSectionAtIndex:(NSInteger)section {
    return UIEdgeInsetsZero;
}

#pragma mark - UICollectionViewDelegate
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {

}

<UICollectionViewDataSource,UICollectionViewDelegate,UICollectionViewDelegateFlowLayout>

- (UICollectionView *)collectionView {
    if (!_collectionView) {
        UICollectionViewFlowLayout *layout = [[UICollectionViewFlowLayout alloc] init];
        layout.minimumLineSpacing = 0;
        layout.minimumInteritemSpacing = 0;
        _collectionView = [[UICollectionView alloc] initWithFrame:CGRectZero collectionViewLayout:layout];
        _collectionView.delegate = self;
        _collectionView.dataSource = self;
        [_collectionView registerClass:[<#collectionViewcell#> class] forCellWithReuseIdentifier:NSStringFromClass(<#collectionViewcell#>.class)];
    }
    return _collectionView;
}

• 3-5 、其他

my_make_attribute

- (NSAttributedString *)makeAttributedStringWithSubTitle :(NSString *)subTitle title:(NSString *)title {
    if (!subTitle.length || !title.length) {
        return nil;
    }
    NSString *str = [NSString stringWithFormat:@"%@%@", subTitle, title];
    NSMutableAttributedString *attribute = [[NSMutableAttributedString alloc] initWithString:str];
    [attribute addAttributes:@{NSFontAttributeName : <#UIFont#>, NSForegroundColorAttributeName : <#UIColor#><##>} range:[str rangeOfString:subTitle]];
    [attribute addAttributes:@{NSFontAttributeName : <#UIFont#>, NSForegroundColorAttributeName : <#UIColor#><##>} range:[str rangeOfString:title]];
    return [attribute copy];
}

my_make_shadow

<#view#>.layer.shadowColor = <#color#>.CGColor;
<#view#>.layer.shadowRadius = 3;
<#view#>.layer.shadowOffset = CGSizeMake(0, 2);
<#view#>.layer.shadowOpacity = 0.1;

my_safe_masonry

 if (@available(iOS 11.0, *)) {
      make.top.mas_equalTo(self.view.mas_safeAreaLayoutGuideTop);
 } else {
      make.top.mas_equalTo(self.view.mas_top);
 }

my_strongify

@strongify(self);

my_weakify

@weakify(self);

个人建议，还是可以手动写的，毕竟自己熟悉的快捷键才是自己的。
此处记录，就是怕后期没保存好或是习惯有调整，先记录此的。
