IOS 开发之操作图库自定义控制器

此类新建完成，在自定义控件中的应用如下：（此自定义控件是一个上传图片的scrollVIew）

新建自定义控件类编辑UIBaseScrollView.h如下

//

#import "UIBaseVIew.h" 
#import "ImageAndPhotos.h" 
 
 
@interface UIBaseScrollView : UIBaseVIew<PhotoButtonDelegate> 
 
@property (nonatomic, strong) NSMutableArray *arrayImgs; 
@property (nonatomic, strong) UIScrollView *scroll; 
@property (nonatomic, strong) ImageAndPhotos *imgChange; 
@property (nonatomic, strong) UIButton *btnImg; 
@property (nonatomic, strong) UIImageView *imgV; 
-(id)initWithFrame:(CGRect)frame CurrenContr:(UIViewController *) crtl; 
 
@end 
编辑定义控件的.m文件如下：

@implementation UIBaseScrollView 
 
-(id)initWithFrame:(CGRect)frame CurrenContr:(UIViewController *) crtl 
{ 
  if (self = [super initWithFrame:frame]) { 
    self.scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; 
     
    self.btnImg = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, frame.size.height-20, frame.size.height-20)]; 
    [self.btnImg setImage:[UIImage imageNamed:@"tizhong_photo_increase_bj"] forState:UIControlStateNormal]; 
     
    self.imgChange = [[ImageAndPhotos alloc] initWithControler:crtl AndButton:self.btnImg]; 
    self.scroll.showsHorizontalScrollIndicator = YES; 
    self.imgChange.delegate = self; 
    [self.scroll addSubview:self.btnImg]; 
    [self addSubview:self.scroll]; 
  } 
  return self; 
} 
 
-(void)setPhotoButton:(ImageAndPhotos *)imgAndP 
{ 
  NSLog(@"%@&&&&&&&&&",self.imgChange.img); 
  if (imgAndP.img) { 
    self.imgV =[[UIImageView alloc] initWithFrame: self.btnImg.frame ]; 
    self.imgV.image = imgAndP.img; 
    self.imgV.backgroundColor = [UIColor yellowColor]; 
    [self.scroll addSubview:self.imgV]; 
    self.btnImg.frame = CGRectMake(CGRectGetMaxX(self.imgV.frame)+10, self.imgV.frame.origin.y, self.imgV.frame.size.width, self.imgV.frame.size.height); 
    self.scroll.contentSize = CGSizeMake(CGRectGetMaxX(imgAndP.btn.frame)+10, 0); 
    if (CGRectGetMaxX(self.btnImg.frame)>self.scroll.frame.size.width) { 
      self.scroll.contentOffset = CGPointMake(self.btnImg.frame.origin.x-10, 0); 
    } 
  } 
 
} 
 
@end 

UIBaseScrollView *det5 = [[UIBaseScrollView alloc] initWithFrame:CGRectMake
(20, CGRectGetMaxY(det4.frame)+20, WIDTH-40, 80) CurrenContr:self];
