这是来自Craig Schamp terremoto的一段代码..在模拟器(os 4.2)上工作正常,但不在设备上。iphone NSNumberFormatter在模拟器上工作不在设备操作系统4.2同时解析
self.currentEarthquake.magnitude = [formatter numberFromString:magString]; and
NSNumber *latituide = [formatter numberFromString:[comp objectAtIndex:0]];
NSNumber *longitude = [formatter numberFromString:[comp objectAtIndex:1]]
设备上是空的,而在模拟器已去所有数据....这里的所有代码....我的设备与4.2 3G是NSNumberFormatter问题???

//<title>M 5.8, Banda Sea</title>

if (components.count > 1) {
// strip the M
NSString *magString = [[[components objectAtIndex:0] componentsSeparatedByString:@" "] objectAtIndex:1];

你可以NSLog`组件吗? – 2010-12-04 21:19:07
