#import "UIKit+ afnetworking. h" #import "UIKit+ afnetworking. h" #import "UIKit+ afnetworking. hCopy the code

Basic usage format:
AFHTTPSessionManager *manager = [AFHTTPSessionManager manager]; /** AFHTTPSessionManager Singleton object configuration */ Manager.securityPolicy = [AFSecurityPolicy policyWithPinningMode:AFSSLPinningModeNone]; / / said do not do the SSL pinning manager. ResponseSerializer = [AFJSONResponseSerializer serializer]; // Response type: Json type manager. ResponseSerializer. AcceptableContentTypes = [NSSet setWithObjects:@"application/json",@"text/json",@"text/javascript",@"text/html",@"text/heml", nil]; / / the type of support manager. RequestSerializer. TimeoutInterval = 6; [Manager GET:urlStr Parameters: Parameters progress:nil Success :^(NSURLSessionDataTask * _Nonnull Task, id _Nullable responseObject) { NSLog(@"JSON DATA: %@", responseObject); } failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) { NSLog(@"Error: %@", error); }];Copy the code

When reencapsulating, block can be used together! Reference: Block Use with Network Requests (AFNetworking).

Masonry

#import "Masonry.h"
Copy the code

Basic usage:

  • New constraint: – (NSArray *)mas_makeConstraints:(void(^)(MASConstraintMaker *make))block;

    [mas_makeConstraints:^(MASConstraintMaker *make) {// only make new constrains (does not exist with Autolayout)}];Copy the code

  • Clear constraint: – (NSArray *)mas_updateConstraints:(void(^)(MASConstraintMaker *make))block;

    [mas_updateConstraints:^(MASConstraintMaker *make) {// // clear all previous constraints, only the latest ones}];Copy the code

Data parsing

  • YYModel
    #import "YYModel.h"
Copy the code

    Basic usage:
    Model class UserInfoLogModel

    “UserInfoLogModel. H” definition:

    @interface UserInfoLogModel: BaseModel // inherit from the BaseModel classCopy the code

    BaseModel class BaseModel
    #import "yyModel. h" @interface BaseModel: NSObject <YYModelCopy the code

    Use of UserInfoLogModel:

    NSDictionary * jsonDict = responseObject[@"DataList"]; / / the JSON data (NSData, nsstrings, NSDictionary) is converted into a Model UserInfoLogModel * userInfoModel = [UserInfoLogModel yy_modelWithJSON:jsonDict ];Copy the code

Demonstration examples 🌰

DetailsOfDiscussModel class: The Key value of JSON is different from the attribute name of the corresponding Model (change the Model attribute name corresponding to the Key of JSON); The Model attribute contains the container type.

DetailsOfDiscussModel. H:
#import "BaseModel.h" @interface DetailsOfDiscussModel : BaseModel @property (nonatomic,strong) NSString * content; @property (nonatomic,strong) NSString * _id; //⭐ ⭐ ⭐ to change the Model attribute name of the Key of JSON ⭐ ⭐ maximal maximal @property (nonatomic,copy) NSArray * members; //⭐ ⭐ ⭐ ⭐ ⭐ @property (nonatomic,strong) NSString * topic; // subject @end @interface DiscussMemberModel: basemodel@property (nonatomic,copy) NSString * avatar; // Avatar @property(nonatomic,copy) NSString * cityCode; @property(nonatomic,copy) NSString * cityName; @property(nonatomic,copy) NSString * countyCode; @property(nonatomic,copy) NSString * countyName; @property(nonatomic,copy) NSString * mobile; @property(nonatomic,copy) NSString * userId; // User id@property (nonatomic,copy) NSString * userName; // User name @endCopy the code

DetailsOfDiscussModel. M:
#import "detailsofdiscussmodel. h" @implementation DetailsOfDiscussModel // Return a Dict with the Model attribute name and Key mapped to JSON. + (NSDictionary *) modelCustomPropertyMapper {return @ {@ "_id" : @ "id" / / ⭐ ️ ⭐ ️ ⭐ ️ change JSON Key corresponding to the Model attribute name ⭐ ️ ⭐ ️ ⭐ ️}; } // Return a Dict, The Model name and Model attribute container need to store the object type + (NSDictionary *) modelContainerPropertyGenericClass {return @{@"members":[DiscussMemberModel class]}; //⭐ ⭐ ⭐ one container type ⭐ ⭐ ⭐} @end @implementation DiscussMemberModel // only implement @endCopy the code

  • JSONModel
    #import "JSONModel.h"
Copy the code

    Basic usage:
    Model class UserInfoLogModel

    “UserInfoLogModel. H” definition:

    @interface UserInfoLogModel: JSONModel // inherited from the JSONModel classCopy the code

    Use of UserInfoLogModel:

    NSDictionary * jsonDict = responseObject[@"DataList"];
NSError* err = nil;
UserInfoLogModel * userInfoModel = [[UserInfoLogModel alloc] initWithDictionary:jsonDict error:&err];

IQKeyboardManager

#import "IQKeyboardManager.h"    
Copy the code

Basic usage:
//IQKeyboardManager singleton object IQKeyboardManager *manager = [IQKeyboardManager sharedManager]; // Disable the function by setting it to YES (default is NO) manager.enable = YES; / / click on the blank area contraction keyboard switch (the default value is NO) manager. ShouldResignOnTouchOutside = YES; / / display its own keyboard toolbar switch (the default value is YES) manager. EnableAutoToolbar = NO;Copy the code

When a particular input box (_editTF) do not need to use the bar on the keyboard: _editTF. InputAccessoryView = [[UIView alloc] init];

Events that need to disable automatic keyboard processing on a certain page:

-(void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];

    [[IQKeyboardManager sharedManager] setEnable:NO];
}

-(void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];

    [[IQKeyboardManager sharedManager] setEnable:YES];
}
Copy the code

MJRefresh

#import "MJRefresh.h"
Copy the code

Basic usage:

(mj_header, mj_footer)

Self. DiscussListTabV. Mj_header = [MJRefreshNormalHeader headerWithRefreshingBlock: ^ {/ / update the drop-down (network request) [weakSelf getDataWith:10 and:0]; }]; Self. DiscussListTabV. Mj_footer = [MJRefreshAutoNormalFooter footerWithRefreshingBlock: ^ {/ / pull refresh request (network) [weakSelf getDataWith:10 and:(int)self.dataArray.count]; }]; Self. discusslistTabv.mj_footer. hidden = NO; // Display "pull up refresh" (for the first time) self. discusslistTabv.mj_footer. hidden = NO; // Display "mj_footer" at the bottom (" pull-up refresh ")Copy the code

Hide and display the bottom “mj_footer” (” pull-up refresh “) :

// When you scroll up and down the tableView, Display (" refresh ") at the bottom of the "mj_footer" - (void) scrollViewWillBeginDragging judging: (scrollView UIScrollView *) {/ / "request to the data already??

Delay stop “chrysanthemum rotation”

  • Delay 0.6s, execute stop method!

    [SVProgressHUD showWithStatus: NSLocaString (@ "loading...")]; [self performSelector:@selector(progressDelayDismiss) withObject:nil afterDelay:0.6f]; -(void)progressDelayDismiss {// Stop "activity indicator" [SVProgressHUD dismiss]; }Copy the code

  • Hide the “SVProgressHUD” singleton class with a GCD delay of 0.6s!

    / / SVProgressHUD offset [SVProgressHUD setOffsetFromCenter: UIOffsetMake (0, 0)]; [SVProgressHUD showWithStatus: NSLocaString (@ "loading...")]; Dispatch_after (dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.6f * NSEC_PER_SEC)), ^{// Fade after 0.6 seconds [SVProgressHUD dismiss]; });Copy the code
  • MBProgressHUD
Basic usage:

  • Display text only:

    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; // Define and load the view to hud. Mode = MBProgressHUDModeText; // Mode: display text hud. Label. text = @" Cannot dial!" ; Hud. Margin = 10.f; Hud. Offset = CGPointMake(0, 0.f); / / hud offset hud. RemoveFromSuperViewOnHide = YES; [hud hideAnimated: YES afterDelay: 1.5 f]; / / 1.5 s backwards away with hud hud. UserInteractionEnabled = NO. // During hud display, the parent view is not available for user interaction!Copy the code

  • Load animation: Rotate the load circle

    MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES]; hud.mode = MBProgressHUDModeCustomView; / / custom views UIImage * image = [[UIImage imageNamed: @ "01"] imageWithRenderingMode: UIImageRenderingModeAlwaysOriginal]; UIImageView *imgView = [[UIImageView alloc] initWithImage:image]; CABasicAnimation *anima = [CABasicAnimation animationWithKeyPath:@" transform.Rotation "]; anima.toValue = @(M_PI*2); Anima. Duration = 1.0 f; anima.repeatCount = 10; [imgView.layer addAnimation:anima forKey:nil]; //layer Animation hud. CustomView = imgView; Hud. Mode = MBProgressHUDModeText; Hud. Label. text = @" loading..." ; hud.margin = 10.f; hud.offset = CGPointMake(0, -100.f); hud.removeFromSuperViewOnHide = YES; [hud hideAnimated: YES afterDelay: 1.5 f]; // Display cycleCopy the code
