权限监测请求工具的封装
下面我们封装一下权限监测和请求工具,直接看代码吧。

JJAuthorizationTypeAllow //允许

}

工具的使用
下面我们就看一下该工具的使用情况,看一下测试代码。
1. ViewController.m
#import "ViewController.h"
#import "JJAuthorityManager.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor yellowColor];
//检查请求通知权限
[JJAuthorityManager jj_checkNotificationAuthorized:^(BOOL authorized) {
if (authorized) {
NSLog(@"已经授权了");
}
else {
[JJAuthorityManager jj_getNotificationAuthorization];
}
}];
sleep(3);
//检查相册权限
JJAuthorizationType type = [JJAuthorityManager jj_checkAlbumAuthorization];
if (type == JJAuthorizationTypeAllow) {
NSLog(@"相册已经授权");
}
else{
[JJAuthorityManager jj_getAlbumAuthorization:^(BOOL authorized) {
if (authorized) {
NSLog(@"相册获取授权成功");
}
else{
NSLog(@"相册获取授权失败");
}
}];
}
}
@end
下面我们看一下效果图。
可见都是先获取权限,没有请求权限弹出的这个弹窗,这里请求相册权限别忘记配置plist权限啊,否则会崩溃的。具体代码可以见刀客传奇 - Github
