MKMapView在iOS 8中显示空白屏幕

问题描述

我遇到了在iOS 8中显示MKMapView的问题。

I am having an issue with displaying a MKMapView in iOS 8.

它在iOS 7中运行良好，现在工作正常，但仅限于模拟器。

It worked fine in iOS 7 and it is working fine now but only on simulator.

在设备上它只显示注释但没有后面的地图。

On device it shows only annotations but no map behind.

它看起来像这样：

我收到的错误：

2014-09-24 22:07:15.349 xxx[1509:265380] Stylesheet does not include style matching tree, or includes an old version.  Perhaps it was compiled by an old version of the style compiler.
2014-09-24 22:07:15.351 xxx[1509:265380] Please create a radar about this! (Check it's not a dup of rdar://16346611 first though)
2014-09-24 22:07:15.351 xxx[1509:265380] Active tile set: GEOActiveTileSet

我的代码：

    CLLocationCoordinate2D coord = CLLocationCoordinate2DMake(21.779998, 59.447816);

    MKCoordinateSpan span = MKCoordinateSpanMake(0.007, 0.007);
    MKCoordinateRegion region = {coord, span};

    MKPointAnnotation *annotation = [[MKPointAnnotation alloc] init];
    [annotation setCoordinate:coord];
    [annotation setTitle:@"yyy"];

    [self.cell.myMapView setRegion:region];
    [self.cell.myMapView addAnnotation:annotation];
    [self.cell.myMapView setDelegate:self];

提前致谢！

将CoreGraphics框架链接到您的目标。应该解决这个问题。

Link CoreGraphics framework to your target. Should fix that.
