导入 libqrencode文件，很小的 添加 #import "QRCodeGenerator.h" @property (strong , nonatomic) UIImageView* qRImageView; - (void)viewDidLoad { [super viewDidLoad]; self.qRImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 400)]; [self.view addSubview:self.qRImageView]; } -(IBAction)qrBtnPress:(id)sender { self.qRImageView.image = [QRCodeGenerator qrImageForString:@"二维码存储的字符串信息 asddsdd" imageSize:self.qRImageView.bounds.size.width]; }

//附上一段object-c解析代码 NSArray *ary = [NSArray arrayWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"ProvinceCityDistrict" ofType:@"plist"]]; for (int i = 0; i < ary.count; i ++) { NSDictionary *province = ary[i]; for(NSString *akey in province){ NSLog(@"%@",akey); NSDictionary *p0 = province[akey]; [mProvinceAry addObject:akey]; for(NSString *city in p0){ NSDictionary *citys = p0[city]; for(NSString *shen in citys){ NSLog(@"%@",shen); NSMutableArray *xians = citys[shen]; for (int y = 0; y < xians.count; y++) { NSLog(@"%@",xians[y]); } } } } }
