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。。。
