Adding Older iOS SDKs to Xcode 4.1 in Lion -

-

i installed lion , xcode 4.1. how add older sdks can build , run in 4.1 or 4.2 in iphone/ipad simulator? xcode 4.1 comes ios 4.3 sdk.

does lion have sort of minimum sdk builds?

thanks,

actually is possible add older sdks long can still hands on older version of xcode older sdk. it's useful sometimes: when find out unsupported constants , methods may using during compile rather @ runtime. here's how it.

  1. get hold of older version of xcode older sdk. apple ios dev center lists 4.3 sdk xcode 3.2.6 download.

  2. mount dmg , open packages folder hidden within dmg via terminal:

    open /volumes/xcode\ and\ ios\ sdk/packages/

  3. double click pkg file sdk version want. looking iphonesdk4_3.pkg but, in addition 4.3, found packages old iphonesdk3_0.pkg. perhaps older sdks may still packaged app store download if know find (i didn't).

  4. let install in it's own folder of choice since won't able force install in applications/xcode.app/contents/developer (which developer folder now)

  5. you'll find package installed in platforms folder in volume chose. move relevant sdk on developer folder within xcode.app. you'll have use sudo:

    sudo mv /platforms/iphoneos.platform/developer/sdks/iphoneos4.3.sdk /applications/xcode.app/contents/developer/platforms/iphoneos.platform/developer/sdks/

  6. restart xcode , should see new (old) sdk listed in options base sdk. yay!

if "older sdk" you're trying add comes bundled in xcode 4.3 or later, adding sdk simple downloading xcode dev center link says "looking older version of xcode?" (currently points here), mounting dmg, copying relevant files over.

in terminal, you'd (edit appropriate sdk version number):

cp -r /volumes/xcode/xcode.app/contents/developer/platforms/iphoneos.platform/developer/sdks/iphoneos6.1.sdk /applications/xcode.app/contents/developer/platforms/iphoneos.platform/developer/sdks/

for sdks versions of xcode prior 4.3, older steps still relevant.

i found happens work getting xcode 5 gm compile builds carry old ios 6 ui when deployed on ios 7 devices. useful fixing bugs pending ui redesign. said, there's got easier way ios 6 ui on ios 7 device.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

i need sort through array , sort each individual row in array in ascending order. doesn't seem going (surprise!) keep getting hit 2 errors: a2101: cannot add 2 relocatable labels , a2026: constant expected here's sort, makes sense me, think i'm still trying implement high-lvl language techniqes assembly. there way around not being able use relative values?
