这是 Craig Schamp 的一段 terremoto 代码 .. 在模拟器 (os 4.2) 上运行良好,但在设备上运行良好。
self.currentEarthquake.magnitude = [formatter numberFromString:magString]; and
NSNumber *latituide = [formatter numberFromString:[comp objectAtIndex:0]];
NSNumber *longitude = [formatter numberFromString:[comp objectAtIndex:1]]
设备上为空,而模拟器上有所有数据....这里所有代码....我的设备是 3g 和 4.2 是 NSNumberFormatter 问题???
