【问题描述】:
我有这段代码:
- (IBAction)registerAction:(id)sender {
[NSThread detachNewThreadSelector:@selector(registerThread) toTarget:self withObject:nil];
}
- (void)registerThread {
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
MyDelegate *delegate = (MyDelegate *)[[UIApplication sharedApplication] delegate];
NSInteger locationID = [delegate.api checkCoordinate:[NSString stringWithFormat:@"%f,%f",
location.coordinate.latitude, location.coordinate.longitude]];
NSNumber *status = [api registerWithUsername:usernameField.text
password:passwordField.text email:emailField.text andLocation:locationID];
[self performSelectorOnMainThread:@selector(registrationDoneWithStatus:) withObject:[NSNumber numberWithInt:1] waitUntilDone:NO];
[pool release];
}
效果很好,但有时我会收到此错误:
void _WebThreadLockFromAnyThread(bool), 0x6157e30: Obtaining the web lock from a thread other than the main thread or the web thread. UIKit should not be called from a secondary thread.
而且似乎只使用委托我得到这个错误,我不知道如何解决。
提前致谢:)
