我的应用程序在模拟器上工作正常,但是当我在设计上运行时,它第一次运行然后崩溃。应用程序崩溃了这段代码:
NSDictionary *dict = [[NSDictionary alloc] initWithObjectsAndKeys:userId, @"userID", pseudoField.text, @"pseudo", birthdateField.text,@"birthdate",sex,@"sex",countryField.text,@"country",cityField.text,@"city",mail,@"mail",token,@"token",tokenExp,@"token", tokenExp,@"tokenEpr", altitude,@"altitude",longitude,@"longitude",pictureLink,@"pic", nil];
如果我删除
altitude,@"altitude",longitude,@"longitude",pictureLink,@"pic" ,
它工作正常,如果我让其中一个,这个冲突。
这是3个变量的代码。
在.h
NSString *altitude;
NSString *longitude;
NSString *pictureLink;
@property(retain,nonatomic) NSString *pictureLink;
@property(retain,nonatomic) NSString *altitude;
@property(retain,nonatomic) NSString *longitude;
in .m

答案 0 :(得分:4)
除非您非常确定自己在做什么,否则不应直接指定属性。使用self.
。一个副作用是它将保留价值。由于您没有保留该值,因此它已被取消分配,当您稍后尝试使用它时,您会崩溃。
- (void)locationUpdate:(CLLocation *)location {
self.altitude = [NSString stringWithFormat:@"%f", location.coordinate.latitude];
self.longitude = [NSString stringWithFormat:@"%f", location.coordinate.longitude];
}
