我现在面临一个非常奇怪的问题.获取[[self view] bounds] .size.width总是320它根据设备没有改变. iPhone 5,6& 6加上所有的方法返回320.000000.
- (void)viewDidLoad
{
[super viewDidLoad];
NSLog(@"%f",[[self view] bounds].size.width);
}
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
NSLog(@"%f",[[self view] bounds].size.width);
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
NSLog(@"%f",[[self view] bounds].size.width);
}

即使是启动画面也在那里.
如何获得视图的实际大小？
解决方法
使用
NSLog(@"%f",[[UIScreen mainScreen] bounds].size.width);
代替
NSLog(@"%f",[[self view] bounds].size.width);
它给你预期的w / h.
