我有以下代碼爲CLLocationManager委託,當我在模擬器上測試它工作得很好,但是當我將它移植到我的iPad時,我得到了一個警告,應用程序凍結。爲什麼是這樣?UIAlertView設備上的問題
- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle: @"Pinging GPS"
message: [NSString stringWithFormat: @"%@, %@",newLocation.coordinate.latitude,newLocation.coordinate.longitude]
delegate: nil
cancelButtonTitle:@"OK"
otherButtonTitles:nil];
NSString * newAudioFile = [[NSBundle mainBundle] pathForResource:@"enter" ofType:@"mp3"];
AVAudioPlayer * av = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:newAudioFile] error:NULL];
[av play];
[alert show];
[alert release];
}
我得到的警告是:
warning: Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.1 (8G4)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (file not found).
如果我刪除了UIAlertView中,它工作得很好而沒有警告
事實證明,問題是我在函數中有一個stopMonitoringForRegion,但是,謝謝你指出這一點 – aherlambang 2011-04-05 04:28:22
