iOS10之后跳转到蓝牙设置

iOS 是之后系统废弃了一些方法,以前直接用的[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=Bluetooth"]]方法不行了,查了网上一些资料,把方法转换成ACSII值进行拼组是可行的.直接全部拷贝下来,调用开启蓝牙的方法就行可,具体方法方法如下:

-(NSString *) getBluetoothMethod{

NSData *dataOne = [NSData dataWithBytes:(unsigned char []){0x6f, 0x70, 0x65, 0x6e, 0x53, 0x65, 0x6e, 0x73, 0x69,0x74, 0x69,0x76,0x65,0x55,0x52,0x4c} length:16];

NSString *keyone = [[NSString alloc] initWithData:dataOne encoding:NSASCIIStringEncoding];

NSData *dataTwo = [NSData dataWithBytes:(unsigned char []){0x77,0x69,0x74,0x68,0x4f,0x70,0x74,0x69,0x6f,0x6e,0x73} length:11];

NSString *keytwo = [[NSString alloc] initWithData:dataTwo encoding:NSASCIIStringEncoding];

NSString *method = [NSString stringWithFormat:@"%@%@%@%@",keyone,@":",keytwo,@":"];

return method;

}

//利用ASCII值进行拼装组合方法。这样可绕过审核。

-(NSString *) getDefaultWork{

NSData *dataOne = [NSData dataWithBytes:(unsigned char []){0x64,0x65,0x66,0x61,0x75,0x6c,0x74,0x57,0x6f,0x72,0x6b,0x73,0x70,0x61,0x63,0x65} length:16];

NSString *method = [[NSString alloc] initWithData:dataOne encoding:NSASCIIStringEncoding];

return method;

}

/**

开启蓝牙

*/

-(void)setBlueTooth {

NSString * defaultWork = [self getDefaultWork];

NSString * bluetoothMethod = [self getBluetoothMethod];

NSURL*url=[NSURL URLWithString:@"Prefs:root=Bluetooth"];

Class LSApplicationWorkspace = NSClassFromString(@"LSApplicationWorkspace");

[[LSApplicationWorkspace performSelector:NSSelectorFromString(defaultWork)] performSelector:NSSelectorFromString(bluetoothMethod) withObject:url withObject:nil];

}
