Workarounds for Cllocationmanager and Mkmapview showuserlocation failures in IOS 8

When the original Xcode 5.1.1 program was compiled with Xcode 6, it was found that the original written Cllocationmanager code and Mkmapview showuserlocation failed. Checked, XCode 6 uses the iOS 8 SDK to compile the app, you need to call Cllocationmanage's Requestalwaysauthorization method.

The procedure is as follows:

1. In the Didfinishlaunchingwithoptions: Method of Appdelegate [Self.window makekeyandvisible]; Then add the following code

    Cllocationmanager *locationmanager = [[Cllocationmanager alloc] init];    Determine if IOS 8    if ([Locationmanager respondstoselector: @selector (requestalwaysauthorization)]) {        [ Locationmanager Requestalwaysauthorization]; Perpetual authorization        [Locationmanager requestwheninuseauthorization];//Authorization in Use    }    [Locationmanager Startupdatinglocation];

2. Add in Info.plist:
Nslocationwheninusedescription, allowing GPS descriptions to be obtained at the front desk
Nslocationalwaysusagedescription, allows the description of GPs to be acquired in the background

Complete.
