iOS开发中几个常用的工具类的简单封装

一.UILabel，UIButton, UIImageView ,UIAlertController的封装

新建一个类，.h文件代码如下：

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface ZlmUI : NSObject
//UILabel
+(UILabel*)createLabelWithFram:(CGRect)cg andFont:(CGFloat)font andTextalignment:(NSInteger)alignment andTextColor:(UIColor *)color andText:(NSString *)text;
//UIImageView
+(UIImageView *)createImageViewWithFram:(CGRect)cg andImageName:(NSString *)name;
//UIButton
+(UIButton *)createButtonWithFram:(CGRect)cg andTarget:(id)target andSelector:(SEL)sel andTitleColor:(UIColor *)color andBackGroundImage:(NSString *)name andTitle:(NSString *)text;
// 弹框提示信息 自定义弹框
+(void)alertWithTitle:(NSString *)title message:(NSString *)message buttonTitle:(NSArray *)buttonTitle confirm:(void(^)(void))ok cancel:(void(^)(void))cancel inController:(UIViewController *)controller;
@end

.m文件代码如下

#import "ZlmUI.h"

@implementation ZlmUI
+(UILabel*)createLabelWithFram:(CGRect)cg andFont:(CGFloat)font andTextalignment:(NSInteger)alignment andTextColor:(UIColor *)color andText:(NSString *)text{
    UILabel *lable=[[UILabel alloc]init];
    lable.frame=cg;
    lable.font=[UIFont systemFontOfSize:font];
    lable.userInteractionEnabled=YES;
    lable.textAlignment=alignment;
    lable.textColor=color;
    lable.text=text;
    return lable;
}
+(UIImageView *)createImageViewWithFram:(CGRect)cg andImageName:(NSString *)name{
    UIImageView *imageV=[[UIImageView alloc]initWithFrame:cg];
    imageV.userInteractionEnabled=YES;
    imageV.image=[UIImage imageNamed:name];
    return imageV;
}
+(UIButton *)createButtonWithFram:(CGRect)cg andTarget:(id)target andSelector:(SEL)sel andTitleColor:(UIColor *)color andBackGroundImage:(NSString *)name andTitle:(NSString *)text{
    UIButton *bt = [UIButton buttonWithType:UIButtonTypeCustom];
    [bt addTarget:target action:sel forControlEvents:UIControlEventTouchUpInside];
    [bt setTitle:text forState:UIControlStateNormal];
    [bt setTitleColor:color forState:UIControlStateNormal];
    [bt setBackgroundImage:[UIImage imageNamed:name] forState:UIControlStateNormal];
    bt.frame=cg;
    return bt;
    
}
+(void)alertWithTitle:(NSString *)title message:(NSString *)message buttonTitle:(NSArray *)buttonTitle confirm:(void (^)(void))ok cancel:(void (^)(void))cancel inController:(UIViewController *)controller{
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:title message:message preferredStyle:UIAlertControllerStyleAlert];
    
    NSString *str = buttonTitle[0];
    UIAlertAction *action = [UIAlertAction actionWithTitle:str style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        if (ok) {
            ok();//处理
        }
    }];
    [alertController addAction:action];
    
    str = buttonTitle[1];
    action = [UIAlertAction actionWithTitle:str style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        if (cancel) {
            cancel();//处理
        }
    }];
    [alertController addAction:action];
    
    
    [controller presentViewController:alertController animated:YES completion:nil];
}

@end

二.OC AFNetworking3.0的封装

新建一个类，.h文件代码如下：

#import <Foundation/Foundation.h>
#import "MJExtension.h"
#import "NetworkConstant.h"

typedef NS_ENUM(NSInteger, XSRequestType) {
    XSRequestTypeForm = 0,
    XSRequestTypeJSON = 1
};

typedef void (^SuccessAPIBlock)(id responseObject);//请求成功回调
typedef void (^FailureAPIBlock)(NSError *error);//请求失败回调
typedef void (^FormDataBlock)(id AFMultipartFormData);
@interface XSAPIManager : NSObject

+ (instancetype)manager;

// GET方法请求
- (void)GET:(NSString *)URLString parameters:(id)parameters success:(SuccessAPIBlock)success failure:(FailureAPIBlock)failure;

// POST方法请求
- (void)POST:(NSString *)URLString requestType:(XSRequestType)type parameters:(id)parameters success:(SuccessAPIBlock)success failure:(FailureAPIBlock)failure;

// DELETE
- (void)DELETE:(NSString *)URLString parameters:(id)parameters success:(SuccessAPIBlock)success failure:(FailureAPIBlock)failure;

//上传图片
- (void)MemberPOST:(NSString *)URLString requestType:(XSRequestType)type parameters:(id)parameters constructingBodyWithBlock:(FormDataBlock)block success:(SuccessAPIBlock)success failure:(FailureAPIBlock)failure;
@end

.m文件代码如下

#import "XSAPIManager.h"

#import "AFNetworking.h"

static XSAPIManager * _instance = nil;

@interface XSAPIManager ()
@property (strong, nonatomic, readonly) AFHTTPSessionManager *httpRequestManager;
@end

@implementation XSAPIManager

@synthesize httpRequestManager = _httpRequestManager;

#pragma mark - init
+ (instancetype)manager {
    return [[self alloc] init];
}
