代码使用

将CXImageEditTool拖入项目中
示例ViewController代码
ViewController.h

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController


@end

ViewController.m

#import "ViewController.h"
#import "Masonry.h"
#import "CXImageEditView.h"

@interface ViewController ()
@property(nonatomic, strong) UIImageView *editIgv;
@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor blackColor];
    
    _editIgv = [UIImageView new];
    _editIgv.image = [UIImage imageNamed:@"zuo.jpg"];
    _editIgv.contentMode = UIViewContentModeScaleAspectFit;
    _editIgv.userInteractionEnabled = YES;
    [self.view addSubview:_editIgv];
    [_editIgv mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.right.top.bottom.mas_equalTo(0);
    }];
    
    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(tapImage)];
    [_editIgv addGestureRecognizer:tap];
}

//进入图片编辑功能
- (void)tapImage {
    CXImageEditView *editVi = [[CXImageEditView alloc]initWithEditImage:[UIImage imageNamed:@"zuo.jpg"]];
    __weak typeof(self) weakSelf = self;
    __weak typeof(editVi) weakEditVi = editVi;
    editVi.completeEdit = ^(UIImage * _Nonnull resultImg) {
        weakSelf.editIgv.image = resultImg;
        [weakEditVi removeFromSuperview];
    };
    [self.view addSubview:editVi];
    [editVi mas_makeConstraints:^(MASConstraintMaker *make) {
        make.left.right.top.bottom.mas_equalTo(0);
    }];
}
@end
