如何适应iPhone 5的分辨率
每一个UI控件都有一个Aurosizing属性，有向上对齐，有向下对齐，也有向上和向下延伸。以上的这些属性设置好就能适应不同尺寸的界面
关键是区别设备的型号，然后使用不同的frame .我的做法是使用Category。 给UIDevice添加一个自动适配的方法
#define AUTO_RESIZE_TO_IPHONE5(r) UIAutoResizeToPhone5(r)
#define AUTO_POS_TO_IPHONE5(r) UIAutoPositionToPhone5(r)
typedef enum {
UIDeviceModelPhone,
UIDeviceModelPhone5,
UIDeviceModelPad,
} UIDeviceModelType;
@interface UIDevice (deviceModel)
- (UIDeviceModelType)deviceModel;
@end
CGRect
UIAutoResizeToPhone5(CGRect rect);
CGRect
UIAutoPositionToPhone5(CGRect rect);
在.m文件中 实现判断的方法
@implementation UIDevice (deviceModel)
- (UIDeviceModelType)deviceModel
{
if ([self userInterfaceIdiom] == UIUserInterfaceIdiomPad)
return UIDeviceModelPad;
if ([self userInterfaceIdiom] == UIUserInterfaceIdiomPhone &&
CGSizeEqualToSize(CGSizeMake(640, 1136),
[[UIScreen mainScreen] currentMode].size))
return UIDeviceModelPhone5;
return UIDeviceModelPhone;
}
@end
/* auto resize method */
CGRect
UIAutoResizeToPhone5(CGRect rect)
{
if ([[UIDevice currentDevice] deviceModel] == UIDeviceModelPhone5)
rect.size.height += 88;
return rect;
}
CGRect
UIAutoPositionToPhone5(CGRect rect)
{
if ([[UIDevice currentDevice] deviceModel] == UIDeviceModelPhone5)
rect.origin.y += 88;
return rect;
}
在使用的地方，引入这个文件
someView.frame = AUTO_RESIZE_TO_IPHONE5(CGRectMake(0, 0, 320, 480));
即可
写个宏定义
#define iPhone5 ([UIScreen instancesRespondToSelector:@selector(currentMode)] ? CGSizeEqualToSize(CGSizeMake(640, 1136), [[UIScreen mainScreen] currentMode].size) : NO)
在需要改变坐标的地方这么写：
mainView = [[UIView alloc] initWithFrame:CGRectMake(0, 86, 320, 264+(iPhone5 ? 88:0))];
希望有帮助。。。
