不多说了,直接贴代码了,可以直接引用。
.h 文件
#import <Foundation/Foundation.h>
@interface LTImageToolMethod : NSObject
/**
*
@brief 浏览头像
*
*
@param oldImageView 头像所在的imageView
*/
+(void)showImage:(UIImageView*)avatarImageView;
@end
.m中的实现:
#import "LTImageToolMethod.h"
static
CGRect oldframe;
@implementation LTImageToolMethod
+(void)showImage:(UIImageView
*)avatarImageView{
UIImage
*image=avatarImageView.image;
UIWindow
*window=[UIApplication sharedApplication].keyWindow;
UIView
*backgroundView=[[UIView alloc]initWithFrame:CGRectMake(0,
0,
[UIScreen mainScreen].bounds.size.width, [UIScreen mainScreen].bounds.size.height)];
oldframe=[avatarImageView
convertRect:avatarImageView.bounds toView:window];
backgroundView.backgroundColor=[UIColor
blackColor];
backgroundView.alpha=0;
UIImageView
*imageView=[[UIImageView alloc]initWithFrame:oldframe];
imageView.image=image;
imageView.tag=1;
[backgroundView
addSubview:imageView];
[window
addSubview:backgroundView];
UITapGestureRecognizer
*tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(hideImage:)];
[backgroundView
addGestureRecognizer: tap];
[UIView
animateWithDuration:0.3
animations:^{
imageView.frame=CGRectMake(0,([UIScreen
mainScreen].bounds.size.height-image.size.height*[UIScreen mainScreen].bounds.size.width/image.size.width)/2,
[UIScreen mainScreen].bounds.size.width, image.size.height*[UIScreen mainScreen].bounds.size.width/image.size.width);
backgroundView.alpha=1;
}
completion:^(BOOL finished) {
}];
}
+(void)hideImage:(UITapGestureRecognizer*)tap{
UIView
*backgroundView=tap.view;
UIImageView
*imageView=(UIImageView*)[tap.view viewWithTag:1];
[UIView
animateWithDuration:0.3
animations:^{
imageView.frame=oldframe;
backgroundView.alpha=0;
}
completion:^(BOOL finished) {
[backgroundView
removeFromSuperview];
}];
}
@end
OK ,以上就是一个工具就建好了,
在图片点击的方法中直接调用
[LTImageToolMethod showImage: 图片的imageview];
就可以了。
