1、TZImagePickerController

TZImagePickerController是一个封装好的选择相册图片的三方库，支持多选，仿微信的选择图片。可用cocoapods直接导入

使用方法：

1、#import "TZImagePickerController.h"

2、<TZImagePickerControllerDelegate>

3、TZImagePickerController *imagePC=[[TZImagePickerController alloc]initWithMaxImagesCount:1 delegate:self];//设置多选最多支持的最大数量，设置代理

[imagePC setDidFinishPickingPhotosHandle:^(NSArray*imageArray, NSArray *array)

//点击确定后回道主界面

｝］；

[self presentViewController:imagePC animated:YES completion:nil];//跳转

2、RSKImageCropViewController

RSKImageCropViewController是一个用来对相片进行裁剪的三方库。可用cocoapods直接导入。

1、#import "RSKImageCropper.h"

2、<RSKImageCropViewControllerDelegate>

3、RSKImageCropViewController *imageCropVC = [[RSKImageCropViewController alloc] initWithImage:image cropMode:RSKImageCropModeCustom];//传入图片与裁剪框的类型

//RSKImageCropModeCustom-自定义

//RSKImageCropModeCircle-圆形

//RSKImageCropModeSquare-矩形

imageCropVC.delegate = self;

imageCropVC.dataSource=self;

[self.navigationController pushViewController:imageCropVC animated:YES];

如果cropMode为RSKImageCropModeCustom自定义类型，则需要加入RSKImageCropViewControllerDataSource进行自定义裁剪框

- (CGRect)imageCropViewControllerCustomMaskRect:(RSKImageCropViewController *)controller

//返回图片的位置

return CGRectMake(0, (SCREEN_HEIGHT-100)/2, SCREEN_WIDTH, 100);

- (UIBezierPath *)imageCropViewControllerCustomMaskPath:(RSKImageCropViewController *)controller

//返回裁剪框的位置

UIBezierPath *path=[UIBezierPath bezierPathWithRoundedRect:CGRectMake(0, (SCREEN_HEIGHT-100)/2, SCREEN_WIDTH, 100) cornerRadius:0];

return path;

3、TZImagePickerController与RSKImageCropViewController混合使用

首先设置TZImagePickerController最大选择数为1，然后在setDidFinishPickingPhotosHandle的回调中把image传给RSKImageCropViewController即可。

TZImagePickerController *imagePC=[[TZImagePickerController alloc]initWithMaxImagesCount:3 delegate:self];            [imagePC setDidFinishPickingPhotosHandle:^(NSArray*imageArray, NSArray *array)

RSKImageCropViewController *imageCropVC = [[RSKImageCropViewController alloc] initWithImage:imageArray[0] cropMode:RSKImageCropModeCustom];

imageCropVC.delegate = self;

imageCropVC.dataSource=self;

[self.navigationController pushViewController:imageCropVC animated:YES];

];

[self presentViewController:imagePC animated:YES completion:nil];
